DURAN® PURE 818665405 Amber GLS 80 Wide-Mouth Bottle - 1,000 mL, Type I Borosilicate Glass 3.3, 10/Case

DURAN® PURE 818665405 from DWK Life Sciences is a 1,000 mL (1 L) amber wide-mouth pharmaceutical and laboratory glass bottle, manufactured from Type I borosilicate glass 3.3 with a GLS 80® screw-thread finish. It is intended for qualified pharmaceutical, biotechnology, analytical, and laboratory material-handling workflows where broad access, light protection, and detailed manufacturer quality documentation are important.

The exact bottle measures 101 mm outside diameter x 218 mm manufacturer-listed height. The GLS 80 neck has a nominal 80 mm outside mouth/thread diameter, substantially wider than a GL 45 opening. The large opening can simplify filling, dispensing, and access with suitable funnels or tools, particularly when handling powders, granules, bulk intermediates, or compatible viscous preparations.

Amber protection: DWK applies the amber color to the exterior of Type I borosilicate glass and thermally fixes the finish. Its DURAN PURE technical brochure describes less than 10% light transmission from 290-450 nm. This supports evaluation for light-sensitive contents, but is not a guarantee of product-specific photostability or full-spectrum light blocking.

PURE quality controls: DWK specifies 100% visual inspection, single-lot delivery, manufacturing-process traceability, batch hydrolytic-resistance analysis aligned with EP, USP, and JP requirements, and change-control notification. Each manufacturing lot is supported by a Certificate of Analysis (CoA) and Retrace Code traceability.

DWK identifies FDA Type III Packaging Material Drug Master File (DMF) #28042 and China CDE/NMPA registration B20220000306 for DURAN PURE bottles. These references support a user's regulatory qualification process; they do not indicate FDA approval of a finished drug product or universal approval of a specific bottle-and-closure assembly.

Supplied with a protective cover only: The manufacturer explicitly lists SKU 818665405 without a functional GLS 80 screw cap and without a pouring ring. The temporary protective dust cover helps protect the interior during distribution but is not a qualified liquid-storage closure, sterile barrier, or leakproof seal. Order an appropriate GLS 80 cap and any desired pouring accessory separately.

DWK lists the glass bottle as autoclavable, but the standard DURAN PURE range is supplied non-sterile and is not automatically certified particle-free, depyrogenated, or ready for aseptic filling. Any cleaning, sterilization, or filling process must be qualified for the bottle and the separately selected closure.

The DURAN PURE range carries a five-year manufacturer shelf-life designation, with an expiration date tied to the supplied manufacturing lot. This is a bottle-inventory dating convention, not an expiry or stability guarantee for contents placed inside.

Each manufacturer case contains 10 bottles. The nominal 1 L capacity is not a certified volumetric measurement. The exact product listing identifies a marking area, but does not establish a numerical graduation interval or calibrated volume tolerance.

Ordering note: DURAN PURE 818665405 = 1 L amber Type I borosilicate 3.3, GLS 80 wide mouth, 101 x 218 mm, temporary protective dust cover, 10 bottles per case. Functional screw cap and pouring ring are NOT included. The glass bottle is autoclavable but supplied non-sterile.

GLS 80 Wide-Mouth Design

The GLS 80 wide-mouth neck provides a nominal 80 mm outer neck/thread diameter and more open access than GL 25 or GL 45 bottles. This can make it easier to transfer appropriately compatible powders, granules, larger solids, or viscous media, and to fill or empty the bottle with suitable equipment.

The 101 mm dimension refers to the body diameter, not the neck. The 218 mm height is DWK's exact bottle-height specification; installed caps and pouring accessories can change total system clearance.

Closure selection: Use a confirmed GLS 80 component. GL 45 and GLS 80 are different screw-thread systems, and similar bottle capacity does not imply cap interchangeability.

Amber Glass: Light Protection and Chemical Contact

DWK's DURAN PURE amber technology places a thermally fixed coloring layer on the exterior of Type I glass, retaining the underlying borosilicate glass contact surface. DWK documents less than 10% light transmission at 290-450 nm. The bottle can be considered when selecting packaging for appropriately characterized photosensitive materials.

The manufacturer transmission rating does not establish complete opacity, specific drug stability, or universal chemical compatibility. Type I borosilicate resists many laboratory reagents but can be attacked by hydrofluoric acid and strong alkaline conditions. Select a compatible cap and seal for the entire formulation.

DURAN PURE Quality and Traceability
  • 100% visual inspection: Quality review of every bottle.
  • Single-lot presentation: Helps maintain lot integrity for incoming inspection.
  • CoA and Retrace Code: Support manufacturing-lot documentation and traceability.
  • Hydrolytic-resistance analysis: Batch testing according to international pharmacopoeial requirements.
  • Regulatory support: Bottle-family DMF references and quality documentation.
  • Formal change control: Supports review of manufacturer specification changes.
  • Five-year manufacturer shelf life: Controlled lot-level bottle inventory dating.

These programs do not mean the bottles are sterile or certified ready for aseptic filling. Actual lot results, manufacture date, and expiry must be checked against the delivered batch documentation.

Cap and Pouring Ring: Both Sold Separately

The supplied temporary protective cover is intended to limit contamination during shipment and storage. It is not a functional screw cap or qualified liquid-tight seal. The bottle is also supplied without a pouring ring.

DWK lists DURAN PURE GLS 80 screw cap 891169109 as a separate product designed for PURE GLS 80 bottles, with a PTFE-coated silicone seal. DWK's current cap listing describes a PPSU cap body; older DWK technical literature calls the material PSU. Confirm the current polymer specification and order quantity with DWK if those details affect qualification.

Procurement distinction: One case of 818665405 provides 10 amber glass bottles with temporary protective covers. It does not include ten functional GLS 80 caps or pouring rings. Specify both accessories separately when required.

Applications and Selection Guidance
  • Pharmaceutical development and GMP-aligned material handling.
  • Qualified storage of light-sensitive APIs, intermediates, excipients, and reagents.
  • Powder, granule, and viscous-medium handling where wide-mouth access is useful.
  • Biotechnology, diagnostic, and analytical-laboratory production support.
  • Lot-controlled material storage and sample preparation.
  • Applications specifying Type I glass, amber protection, and GLS 80 access.

Transport, sterile filling, and sealed storage require the correct functional closure and any applicable container-closure integrity, packaging, chemical-compatibility, and process validation.

DURAN PURE 818665405 1,000 mL / 1 L Amber Type I Glass GLS 80 Wide Mouth 101 x 218 mm Autoclavable Glass CoA Traceable 10/Case

Technical Overview

DURAN® PURE 818665405 is a 1,000 mL amber wide-mouth bottle made from Type I borosilicate glass 3.3 for pharmaceutical, biotechnology, and analytical laboratory workflows. Its GLS 80® threaded neck allows broader access than conventional GL 45 bottles. DWK specifies 101 mm bottle outside diameter, 218 mm bottle height, and 10 bottles per case.

The manufacturer supplies a temporary protective dust cover to help protect the interior during handling and transportation. The exact product is supplied without a functional GLS 80 screw cap and without a pouring ring. Both must be selected separately if needed for the intended application.

DURAN PURE bottles combine Type I glass with 100% visual inspection, single-lot delivery, a lot-specific Certificate of Analysis (CoA), and documented manufacturing traceability. The amber finish provides manufacturer-documented attenuation over a defined wavelength range.

Exact-SKU takeaway: 818665405 = 1 L amber DURAN PURE, GLS 80, 101 x 218 mm, 10/case. Protective dust cover supplied; functional cap and pouring ring excluded. The glass bottle is autoclavable but delivered non-sterile. Any filled-container configuration requires a separately qualified closure.

Dimensional distinction: The GLS 80 thread refers to the wide neck; 101 mm is the bottle's outside body diameter. The 218 mm height does not establish total clearance with a separately fitted cap. Nominal capacity is not a calibrated dispensing volume.

What Makes GLS 80 Different from GL 45?

The GLS 80 wide mouth is designed to make filling, emptying, and access easier when compared with smaller GL necks. DWK identifies the nominal neck outside diameter as 80 mm. Wide access can be useful with appropriately compatible powders, granules, larger solids, funnels, and viscous media.

FeatureGLS 80GL 45
Nominal thread/neck diameter80 mm45 mm
AccessWider opening for filling and material accessNarrower standard bottle opening
Cap fitRequires matching GLS 80 closureRequires matching GL 45 closure
InterchangeabilityNot interchangeable with GL 45Not interchangeable with GLS 80

A wider opening does not establish a certified pour rate, lower contamination risk in every use, or compatibility with every filling fixture. The specific process and separately selected closure should be qualified.

Amber Glass Technology and Light Protection

DWK applies a thermally fixed amber coloring treatment to the exterior of the Type I borosilicate glass. This preserves the underlying borosilicate interior contact surface. Its DURAN PURE brochure documents light transmission below 10% from 290-450 nm, relevant to the selection of bottles for certain light-sensitive materials.

The optical performance is a manufacturer bottle-family statement, not a lot-specific drug stability test. UV and visible-light sensitivity varies by API, excipient, reagent, and formulation. Establish required storage conditions, light protection, and filled-product shelf life through appropriate testing.

Optical boundary: Less than 10% transmission over the specified region does not mean the glass is completely opaque at all wavelengths or that photodegradation is impossible.

Type I Borosilicate Glass 3.3: Material Properties

The bottle body is DURAN Type I borosilicate glass 3.3, a high-hydrolytic-resistance, low-expansion glass family. DWK's technical documentation identifies the base glass with ISO 3585 and ASTM E438 Type I, Class A. The approximate linear thermal-expansion coefficient is 3.3 x 10-6 K-1, a general glass-property value.

Borosilicate glass provides useful chemical durability for many laboratory substances but is not universally inert. Hydrofluoric acid, strong alkaline solutions, and some aggressive heated chemicals can attack glass. Sample compatibility must also address the separately selected closure and any pouring accessory.

Type I glass and manufacturer hydrolytic testing do not establish a universal extractables/leachables limit, pharmaceutical formulation compatibility, or a validated closure integrity result for the final filled container.

DURAN PURE Pharmaceutical Quality System

DURAN PURE provides additional manufacturing controls and documentation for pharma and biotechnology procurement. The manufacturer's statements include:

  • 100% visual inspection: Every PURE bottle is visually checked.
  • Single-lot delivery: Supports traceable receiving and lot segregation.
  • Hydrolytic-resistance testing: Manufacturing batches analyzed according to EP, USP, and JP requirements.
  • Lot-specific CoA: Documentation for manufacturing-lot quality review.
  • Retrace Code: Supports certificate lookup and production traceability.
  • Formal change control: Process and product change-management notifications.
  • Regulatory support: Type III FDA DMF #28042 and China CDE/NMPA B20220000306 for bottles.
  • Five-year dating: Manufacturer-specified expiry tied to the actual lot.

A DMF reference supports regulatory documentation; it is not FDA approval of a finished drug product. Obtain the delivered lot's current CoA and any needed additional declarations from DWK rather than treating generic statements as lot-specific test results.

Dust Cover, GLS 80 Cap, and Pouring Ring

The included protective dust cover helps limit contamination of the unfilled glass bottle during storage and distribution. It is not a qualified screw cap, sterile barrier, vapor-tight seal, or closure for transporting filled chemicals. DWK states that this exact SKU is supplied without the screw cap and without a pouring ring.

ComponentIncluded with 818665405?Purpose
1 L amber GLS 80 glass bottleYes, 10 per caseType I glass container
Temporary protective coverYesUnfilled bottle interior protection
Functional GLS 80 screw capNoQualified closure, selected separately
Pouring ringNoOptional pouring accessory, selected separately
PTFE-coated silicone sealNot part of bottle-only orderComponent of certain separately sold cap assemblies

Related cap: DURAN PURE 891169109 is DWK's separately sold GLS 80 screw cap with PTFE-coated silicone seal, listed as autoclavable. The current cap product page describes its body as polyphenylsulfone (PPSU), while older DWK brochure/flyer material describes polysulfone (PSU). Request confirmation when exact cap-body material is a regulated or chemical-compatibility requirement.

Cap pack discrepancy: DWK's current online listing displays 5 caps per pack for 891169109, while older PURE technical flyers identify 1 cap per PE bag. These may describe different packaging levels, but the reviewed sources do not reconcile them. Confirm the actual ordering unit on the quotation.

Do not confuse accessories: PURE GL 45 cap 891088679 is not a GLS 80 cap. No specific PURE GLS 80 pouring-ring part number was confirmed for this exact bottle; request a verified compatible accessory before ordering.

Sterility, Autoclavability, and Cleanroom Preparation

DWK's exact SKU designates the glass bottle as autoclavable. DURAN PURE's standard supplied presentation is nevertheless non-sterile and is not automatically certified as particle-free, depyrogenated, or ready-to-use for aseptic filling.

A glass bottle's general suitability for autoclaving does not guarantee that the protective cover, functional cap, optional pouring ring, selected seals, or filled formulation can be processed under the same conditions. The process should use validated temperature, pressure, time, loading, and appropriate venting according to the laboratory's SOP.

DWK offers additional cleaning, depyrogenation, sterilization, and packaging options through customized arrangements. Such options should not be described as included with standard SKU 818665405.

Five-Year Bottle Shelf Life and Lot Expiry

DWK assigns a five-year manufacturer shelf life to DURAN PURE bottles, with an actual expiration date based on the manufacturing lot. Verify the delivered batch label and CoA rather than assuming a new case arrives with five full years remaining.

The manufacturer dating is for controlled bottle inventory. It does not establish the stability, expiration, beyond-use date, or permitted storage period of any drug, reagent, or other substance placed in the bottle.

Chemical Compatibility and Filled-Container Qualification

An assembled GLS 80 container may include borosilicate glass, a high-performance plastic screw cap, a PTFE-coated silicone seal, and a separate pouring ring. Each component can have different compatibility with aqueous solutions, organic solvents, aggressive pH conditions, vapors, and heat.

  • APIs and intermediates: Evaluate photostability, extractables/leachables, and the complete sealing system.
  • Powders and granules: Consider filling access, moisture sensitivity, contamination control, and closure selection.
  • Aqueous media: Check pH, ionic content, closure compatibility, and cleanliness requirements.
  • Organic solvents: Verify all wetted cap, seal, and accessory materials for the specific solvent mixture.
  • Volatile contents: Establish an appropriate vapor barrier and permitted storage/transport configuration.
  • Strong alkalis / hydrofluoric acid: Assess glass attack and consider alternate containers when necessary.
  • Autoclaving: Validate both empty or filled condition and the selected assembly, with appropriate pressure management.

The bottle listing does not provide a universal solvent-compatibility certificate, numerical leak rate, vapor-tight guarantee, or pressure/vacuum rating for a finished container-closure system.
