DURAN® PURE 818063604 Amber Glass Bottle - 250 mL, GL 45, Type I Borosilicate Glass 3.3, 10/Case
DURAN® PURE 818063604 Amber Glass Bottles from DWK Life Sciences are 250 mL pharmaceutical and laboratory containers manufactured from Type I borosilicate glass 3.3. Each bottle features an amber exterior finish, a GL 45 screw-thread neck, and a temporary protective dust cover to help protect the glass interior during storage and transportation.
Designed for demanding pharmaceutical, biotechnology, and analytical laboratory workflows, the DURAN PURE range combines the recognized chemical and thermal characteristics of DURAN glass with enhanced manufacturing controls, quality inspection, batch traceability, and regulatory documentation.
The exact 818063604 bottle has a 250 mL nominal capacity, a 70 mm outside diameter, and a 138 mm manufacturer-listed height. Its GL 45 threaded neck supports separately selected screw caps and closure systems appropriate for the intended chemical, pharmaceutical, or processing application.
Amber light protection: DWK applies a uniform, thermally fixed amber coloration to the exterior of the Type I borosilicate glass. The manufacturer documents a light transmission rate below 10% across the 290-450 nm wavelength range, helping protect suitable light-sensitive pharmaceutical ingredients, intermediates, and laboratory compounds.
Unlike glass whose color is produced throughout its bulk composition, the DURAN PURE amber treatment is applied externally. This preserves the Type I borosilicate glass interior contact surface while providing the manufacturer's documented light-protection performance. Actual formulation stability and storage life must still be established through application-specific testing.
Enhanced pharmaceutical quality: DWK specifies 100% visual inspection, single-lot delivery, 100% manufacturing-process traceability, and batch testing of hydrolytic resistance against applicable European, United States, and Japanese pharmacopoeial requirements. A lot-specific Certificate of Analysis (CoA) supports incoming quality review and regulated manufacturing documentation.
The DURAN PURE quality program also includes formal change-control management and customer notification. DWK identifies an FDA Type III Packaging Material Drug Master File, DMF #28042, for the DURAN PURE bottle range, along with China CDE/NMPA registration B20220000306. These records support regulatory documentation but do not constitute approval of a specific finished drug product or application.
Functional screw cap sold separately: DURAN PURE bottles are supplied with a temporary protective dust cover, not a functional GL 45 storage cap. The protective cover helps reduce contamination during handling and transport but should not be treated as a qualified liquid-storage, solvent-resistant, or leakproof seal.
For compatible pharmaceutical closure applications, DWK separately offers the DURAN PURE GL 45 Premium Screw Cap, SKU 891088679, manufactured from perfluoroalkoxy (PFA) with a PTFE-coated silicone seal. This accessory is supplied separately in packs of five. Appropriate closure material, sealing performance, and processing requirements should be verified for the intended contents.
The exact 818063604 glass bottle is listed as autoclavable. However, standard DURAN PURE bottles are non-sterile as delivered and are not automatically certified particle-free, depyrogenated, or ready for aseptic filling. Any required cleaning, sterilization, or further processing must follow the laboratory's approved qualification procedures.
DWK assigns a formal five-year manufacturer shelf life to DURAN PURE bottles. Each manufacturing lot has an associated expiry date documented on its label and Certificate of Analysis. This expiry applies to the bottle's controlled inventory status, not to any pharmaceutical ingredient or reagent subsequently stored inside.
WHEATON, DURAN, and other laboratory bottles may share similar nominal capacities, but the DURAN PURE Type I glass classification, exterior amber treatment, GL 45 thread, and enhanced documentation program distinguish this configuration. DWK supplies 10 bottles per case.
Ordering note: Specify DURAN PURE 818063604 for the 250 mL amber Type I borosilicate glass 3.3 bottle with GL 45 thread, measuring 70 mm in diameter and 138 mm high. Supplied 10 bottles per case with protective dust covers and lot-specific quality documentation. Functional GL 45 screw caps are not included. The glass bottle is autoclavable but supplied non-sterile.

Amber Light Protection for Pharmaceutical Materials
DWK's DURAN PURE amber coloring technology uses a thermally fixed treatment applied to the outside of the clear Type I borosilicate bottle. This results in a uniform, durable amber finish while retaining the original borosilicate glass as the interior chemical-contact material.
The manufacturer specifies less than 10% light transmission between 290 and 450 nm. This performance is relevant to pharmaceutical and biochemical materials that may degrade when exposed to ultraviolet or shorter-wavelength visible light.
The 250 mL amber configuration can be evaluated for light-sensitive APIs, drug intermediates, reference preparations, formulation-development materials, and other compatible laboratory contents. However, amber glass does not provide guaranteed protection from every wavelength or establish a finished formulation's storage stability.
Light-protection qualification: DWK's documented spectral performance supports bottle selection, but the final product's photostability, storage temperature, oxygen exposure, duration, and closure suitability must be validated separately.
What Makes DURAN PURE Different?
The DURAN PURE product family was developed for pharmaceutical and biotechnology applications where repeatable material specifications, documented manufacturing quality, and traceability are important to supplier qualification and regulated operations.
- 100% visual inspection: Each PURE bottle undergoes visual inspection.
- Single-lot delivery: Supports manufacturing-batch traceability and consistency.
- Batch hydrolytic-resistance testing: Testing aligned with European, United States, and Japanese pharmacopoeial requirements.
- Lot-specific Certificate of Analysis: Supports receiving inspection and documented quality review.
- Retrace Code: Enables connection to manufacturing-lot records.
- Enhanced in-process control: Supports consistency throughout manufacturing.
- Change-control management: Manufacturer notification of relevant changes.
- Regulatory documentation: DMF references and supporting technical records for qualification.
- Protective dust cover: Helps protect the bottle interior during storage and transport.
- Formal manufacturer dating: Five-year shelf life with lot-specific expiration information.
These controls do not mean that standard DURAN PURE bottles arrive sterile, depyrogenated, particle-free certified, or automatically qualified for direct aseptic filling. End-user processing and documentation requirements still apply.
GL 45 Closure Selection: Dust Cover vs. Functional Screw Cap
The included protective cover is not a functional screw cap. Its role is to help minimize contamination of the glass interior during storage and transport. It is not a qualified long-term storage seal or a substitute for a closure selected for the contents and operating conditions.
For filled storage or process use, select a compatible GL 45 screw cap with suitable body and seal materials. Consider chemical resistance, sample stability, vapor containment, sterilization compatibility, and any required container-closure integrity testing.
Related accessory: DURAN PURE 891088679 is a separately sold GL 45 Premium Screw Cap manufactured from PFA with a PTFE-coated silicone liner. DWK lists it as autoclavable, with a manufacturer-specified 200°C maximum temperature, supplied five per pack. These are cap-specific specifications, not additional specifications for the bottle.
Purchasing reminder: One case of 818063604 contains 10 amber bottles and temporary protective covers. A laboratory requiring one functional cap for each bottle should account for the separate closure quantity; for example, two five-packs of compatible GL 45 caps would provide ten caps.
Type I Borosilicate Glass 3.3: Material Characteristics
DURAN PURE 818063604 is manufactured from Type I borosilicate glass 3.3, a laboratory glass family associated with high hydrolytic resistance, low thermal expansion, and good chemical durability.
DWK identifies the base glass with ISO 3585 and the ASTM E438 Type I, Class A classification. The PURE manufacturing program further supports pharmaceutical quality review through actual batch hydrolytic-resistance analysis and lot-specific documentation.
Although borosilicate glass is resistant to many laboratory chemicals, it is not universally inert. Hydrofluoric acid, strong alkaline solutions, and other aggressive conditions can attack glass. Chemical compatibility must also consider the selected GL 45 cap, seal, and actual formulation.
