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 the GL 45 media bottle to Class A volumetric flasks, via vials and serum bottles, DWK equips R&D, quality control and pilot production. Its promise: dimensional accuracy, chemical resistance and full traceability for reproducible, safe results in modern labs. With a coherent, well-documented portfolio, the brand streamlines procurement and guarantees accessory compatibility.

A cutting-edge industry player born of three pioneers

DWK was born from the union of three pioneers: Duran Group (borosilicate glass 3.3), Wheaton (primary packaging and vials) and Kimble (volumetric glassware). With more than a century of glassmaking expertise, the company has its roots in Europe and North America while operating an international manufacturing network. The goal remains constant: to provide reliable, standard-compliant laboratory glassware designed for everyday use. From the ergonomics of the DURAN YOUTILITY bottles to the wide-neck GLS 80, practical innovation drives its development, backed by stringent quality and service standards. Bringing the brands together has harmonised standards, enabled investment in next-generation furnaces and delivered global logistics. Every batch carries a Retrace Code giving access to manufacturing data. Over the years, DWK has expanded its ranges with amber versions for light protection, safety coatings (Protect) and ready-to-use solutions for pharma and analytical applications.

Expertise and areas of specialisation

DWK stands out for its mastery of borosilicate glass 3.3 for demanding life-science, analytical and quality control applications. DURAN bottles (GL 45, GLS 80) deliver excellent thermal and chemical resistance, durable graduations and proven autoclavability. Amber variants shield light-sensitive samples, while Protect models add shatter protection. A wide range of caps and closures (PP, PBT, PTFE-liner) ensures leak-tightness and process fit.

For volumetric work, KIMBLE provides volumetric flasks, cylinders and pipettes Class A that comply with international tolerances, with batch certificates available. Long-lasting markings (fired-on enamel) and careful design ensure accuracy and readability, essential in QC and R&D.

For packaging and small-scale production, WHEATON offers vials for HPLC/GC, headspace vials and serum bottles in Type I glass for sensitive applications. Cap/septa combinations (PTFE/silicone, butyl, …) cover sealing, inertness and temperature requirements. 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 USP/EP pharmacopoeias for glass). Retrace Code traceability, dimensional consistency (threads GL 45, GLS 80) and accessory compatibility simplify lab integration. By prioritising durable, reusable materials, DWK also helps reduce the environmental footprint of operations 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 applications).

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

Are GL 45/GLS 80 caps compatible across ranges?
GL 45 and GLS 80 are standardised threads. DWK caps are compatible within these standards. However, check materials (PP, PBT, PTFE liner) and conditions of use.

What certificates can DWK provide?
Depending on the item: certificates of conformity for Class A, batch information via the Retrace Code, and material declarations (USP/EP Type I for 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 is DWK taking?
Priority to reusable products, recyclable glass, extended service life (Protect, YOUTILITY) and optimised packaging. The aim: technical performance with less impact.
