GLW : What floorutions for storing and identifying the samples to ultra-low temperature?

German manufacturer, GLW designs freezer boxes, racks and sample storage accessories for demanding laboratories: biobanks, quality control, biomedical and environmental research. Its polycarbonate and polypropylene solutions deliver dimensional stability at ultra-low temperatures and through autoclaving, with alphanumeric indexing and colour coding for error-free archiving. A robust, reliable and long-lasting range, compatible with ULT freezers and everyday benchtop workflows.

A laboratory cold storage specialist that has become the benchmark

Rooted in German plastics engineering, GLW has built its reputation on a simple idea: precise containers make sample collections reliable. Over the years, the brand has broadened its portfolio of boxes and racks to keep pace with the rise of biobanks and translational medicine, while staying focused on material consistency, dimensional stability and day-to-day ergonomics. The adoption of standard formats (9×9 and 10×10 grids, standard drawer footprints) and tightly controlled manufacturing opened the doors to Europe’s laboratories. Working alongside specialist distributors such as Dutscher, GLW favours technical proximity: clear ranges, ready availability, and improvements driven by real-world practice.

Expertise and areas of specialisation

The core expertise of GLW lies in cryogenic storage and ULT solutions ready for everyday use: freezer boxes in polycarbonate (clarity, rigidity) and polypropylene (lightweight, chemical resistance), with 81-place or 100-place grids for 1–2 ml cryovials, inserts for microtubes and tall versions for 15/50 ml tubes. Clear lids with alphanumeric indexing and colour-coding options provide immediate identification, reduce errors and streamline inventory. The cold-ready design (anti-drip surfaces, drain holes, secure stackability) withstands cycles from –196 °C (vapour phase) to +121 °C (autoclaving, depending on model). These features meet the demands of biobanks, cell culture, quality control platforms and clinical laboratories, where sample integrity determines the validity of results. Consistent dimensions make drawer storage, visual traceability and series-based organisation straightforward. By relying on proven materials and careful manufacturing, GLW limits premature wear, reduces replacements and contributes to sustainability through reuse. For teams, the benefit is direct: less time spent searching, more reliable stocktakes and safer cold storage.
