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 references 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 hallmarks are dimensional accuracy, chemical resistance and traceability, delivering reproducible, safe results in modern laboratories. With a coherent, well-documented portfolio, the brand streamlines procurement and guarantees accessory compatibility.

A cutting-edge leader born of three pioneers

DWK was born from the merger of three pioneers: Duran Group (borosilicate glass 3.3), Wheaton (bottles and vials) and Kimble (volumetric glassware). With more than a century of glassmaking expertise, the company is rooted in Europe and North America while operating an international manufacturing network. The goal remains the same: to deliver reliable, standards-compliant glassware designed for everyday use. From the ergonomics of DURAN YOUTILITY bottles to the wide-neck GLS 80, practical innovation drives its development, underpinned by stringent quality and service standards. Brand consolidation has made it possible to harmonise standards, invest in next-generation furnaces and offer worldwide 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 pharmaceutical 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 workflows. DURAN bottles (GL 45, GLS 80) deliver excellent thermal and chemical resistance, durable graduations and proven autoclavability. The amber versions protect light-sensitive samples, while Protect models add a shatter-resistant safety coating. A wide range of caps and closures (PP, PBT, PTFE-liner) ensures sealing integrity and process compatibility.

For volumetric metrology, KIMBLE supplies Class A volumetric flasks, graduated cylinders and pipettes compliant with international tolerances, with batch certificates available. High-durability markings (ceramic enamel) and careful design ensure accuracy and readability, essential in QC and R&D.

On the packaging and small-scale production side, WHEATON offers vials for HPLC/GC, headspace vials and serum bottles in Type I glass for sensitive applications. Cap/septa combinations (PTFE/silicone, butyl, etc.) cover sealing, inertness and temperature-resistance needs. Pre-cleaned or ready-to-use options are available depending on the reference.

The portfolio is built on recognised standards (e.g. ISO 4796 for bottles, ASTM E438 and the USP/EP pharmacopoeias for glass). Traceability via Retrace Code, dimensional consistency (threads GL 45, GLS 80) and accessory compatibility make lab implementation straightforward. By prioritising durable, reusable materials, DWK also helps reduce the 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 (volumetric glassware, Class A) 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 validated cycles to preserve markings and mechanical integrity.

Are GL 45/GLS 80 caps compatible across references?
GL 45 and GLS 80 are standardised thread forms. DWK caps are compatible within those standards. Do check the materials (PP, PBT, PTFE liner) and intended use conditions.

What certificates can DWK provide?
Depending on the item: certificates of conformity for Class A, batch information via the 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 analytics and QC.

What sustainability actions is DWK taking?
Priority on reusables, recyclable glass, extended service life (Protect, YOUTILITY) and optimised packaging. The goal: technical performance with a smaller footprint.
