DWK Life Sciences : What floorutions for laboratory glassware and packaging in the laboratory?

DWK Life Sciences brings together the DURAN, WHEATON and KIMBLE brands, global benchmarks in laboratory glassware and primary packaging. From GL 45 media bottles to Class A volumetric flasks, via vials and serum bottles, DWK equips R&D, quality control and pilot-scale production. Its ethos: dimensional accuracy, chemical resistance and traceability, for reproducible, safe results in modern laboratories. With a coherent, well-documented portfolio, the brand streamlines purchasing and ensures accessory compatibility.

An industry-leading force born of three pioneers

DWK was born from the merger of three pioneers: Duran Group (borosilicate 3.3 glass), Wheaton (containers and vials) and Kimble (volumetric glassware). Heir to more than a century of glassmaking expertise, the company has deep roots in Europe and North America while operating an international manufacturing network. The goal remains the same: to deliver reliable, standards-compliant laboratory glassware for everyday use. From the ergonomics of the DURAN YOUTILITY bottles to the wide-neck GLS 80, practical innovation drives its development, underpinned by rigorous quality and service. Consolidating the brands has harmonised standards, enabled investment in next-generation furnaces and delivered global logistics. Every batch carries a Retrace Code that provides access to manufacturing data for full traceability. Over the years, DWK has expanded its ranges with amber versions for light protection, safety coatings (Protect) and ready-to-use solutions for the pharmaceutical and analytical sectors.

Expertise and Areas of Specialisation

DWK stands out for its mastery of borosilicate glass 3.3 for the demanding needs of life sciences, analytical work and quality control. DURAN bottles (GL 45, GLS 80) offer outstanding thermal and chemical resistance, hard-wearing graduations and proven autoclavability. amber variants protect light-sensitive samples, while Protect models add anti-shatter safety. A broad range of caps and closures (PP, PBT, PTFE-liner) ensures leak-tightness and process fit.

For liquid metrology, KIMBLE supplies Class A volumetric flasks, cylinders and pipettes to international tolerances, with batch certificates available. High-durability markings (ceramic enamel) and considered design deliver accuracy and legibility, essential in QC and R&D.

For packaging and small-scale production, WHEATON offers vials for HPLC/GC, headspace bottles and serum bottles in Type I glass for sensitive applications. Cap/septa pairings (PTFE/silicone, butyl, etc.) cover requirements for seal integrity, inertness and temperature endurance. Pre-cleaned or ready-to-use versions are available depending on the reference.

The portfolio is built on recognised standards (e.g. ISO 4796 for bottles, ASTM E438 and pharmacopoeias USP/EP for glass). Retrace Code traceability, dimensional consistency (threads GL 45, GLS 80) and accessory compatibility simplify laboratory implementation. By favouring durable, reusable materials, DWK also helps reduce the operational footprint without compromising performance.

Frequently asked questions about the DWK brand

Which brands make up DWK and what do they cover?
DWK brings together DURAN (bottles and borosilicate glassware), KIMBLE (Class A volumetric glassware) and WHEATON (vials and bottles for analytical and pharma).

Is DURAN glass autoclavable?
Yes, borosilicate 3.3 withstands autoclaving (121–134 °C). Loosen caps, avoid thermal shock and follow validated cycles to preserve markings and mechanical integrity.

Are GL 45/GLS 80 caps cross-compatible?
GL 45 and GLS 80 are standardised threads. DWK caps are compatible within these standards. Still verify materials (PP, PBT, PTFE liner) and conditions of use.

Which certificates can DWK supply?
Depending on the item: certificates of conformity for Class A, batch information via Retrace Code, and material statements (USP/Ph. Eur. Type I glass) available on request.

Why choose DWK for quality control?
Tight tolerances, accurate volumes, chemical resistance and traceability. Dimensional consistency reduces variability and safeguards your methods in analytical work and QC.

What sustainability actions does DWK take?
Focus on reusable products, recyclable glass, extended service life (Protect, YOUTILITY) and optimised packaging. The goal: technical performance with less impact.
