Technical Overview
DURAN® PURE 818666307 is a 2,000 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 136 mm bottle outside diameter, 248 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: 818666307 = 2 L amber DURAN PURE, GLS 80, 136 x 248 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; 136 mm is the bottle's outside body diameter. The 248 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.
| Feature | GLS 80 | GL 45 |
|---|
| Nominal thread/neck diameter | 80 mm | 45 mm |
| Access | Wider opening for filling and material access | Narrower standard bottle opening |
| Cap fit | Requires matching GLS 80 closure | Requires matching GL 45 closure |
| Interchangeability | Not interchangeable with GL 45 | Not 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.
| Component | Included with 818666307? | Purpose |
|---|
| 2 L amber GLS 80 glass bottle | Yes, 10 per case | Type I glass container |
| Temporary protective cover | Yes | Unfilled bottle interior protection |
| Functional GLS 80 screw cap | No | Qualified closure, selected separately |
| Pouring ring | No | Optional pouring accessory, selected separately |
| PTFE-coated silicone seal | Not part of bottle-only order | Component 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 818666307.
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.
