Lenz : What glassware for the distillation, synthesis and the montages of laboratory?

Lenz designs and manufactures in Germany high-end laboratory glassware made from borosilicate 3.3 glass, built for the demands of modern labs. With DIN/ISO standard ground joints, distillation and synthesis set-ups, columns, condensers, reactors and accessories, the brand serves R&D, quality control and production in the food and beverage, chemical, pharmaceutical and environmental sectors. Robust construction, precise fit and compatibility across standards make Lenz a dependable partner day in, day out.

Glass craftsmanship that endures — made to last in the lab

Rooted in German glassmaking heritage, Lenz is built on a simple idea: turning artisan craftsmanship into industrial precision for science. Over the decades, the brand has honed its borosilicate 3.3 processing and ground-glass joint finishing to deliver components that are truly interchangeable, durable and safe. In tune with the needs of chemists and microbiologists, it evolves parts and assemblies based on real-world use: greater vacuum integrity, improved thermal stability and more ergonomic set-ups. Today, Lenz is a recognised partner to European laboratories, combining consistent quality, DIN/ISO compatibility and attentive service through specialist distributors.

Expertise and Specialisations

Lenz’s expertise covers the essential glass apparatus for chemistry and bioprocess operations. At the core of the portfolio: standard ground-glass joints (cones, sockets, adapters) that ensure leak-tight, reproducible assemblies, compatible with DIN/ISO standards. The brand offers a wide choice of condensers (Liebig, Allihn, Dimroth), columns (fractionation, absorption), distillation apparatus, extractors, flasks and jointing accessories to build robust lines for synthesis, purification and concentration.

For sample preparation and quality control, Lenz supplies filtration components and sintered glass, funnels, connectors and taps (PTFE stopcocks) that deliver fine flow regulation, including under vacuum. Glass reactors and associated components make lab scale-up straightforward, with excellent process visibility and the high chemical resistance of borosilicate glass 3.3.

Why do laboratories choose Lenz? For the machining precision of the joints, dimensional stability and thermal resistance, all critical for heat–cool cycles. The cross-compatibility of parts simplifies maintenance and gives flexibility in set-ups. Finally, the inherent durability of glass and the repairability of many items support responsible purchasing by reducing consumption and waste.

In short: reliable, standardised and long-lasting glassware, perfectly suited to regulated R&D, QC and production environments.

FAQs about the Lenz brand

What material are Lenz components made from?
From borosilicate glass 3.3, renowned for its chemical resistance and thermal shock performance, manufactured to the relevant DIN/ISO standards for laboratory apparatus.

Are Lenz ground-glass joints compatible with other brands?
Yes. The joints follow DIN/ISO dimensions for reliable interchangeability. However, check tolerances and wear before assembly.

Can these components be used under vacuum or at high temperature?
Yes, as specified for each item. Observe controlled heating/cooling rates and avoid thermal or mechanical shock to maintain seal integrity.

Does Lenz offer items geared towards distillation and synthesis?
Yes. Condensers, columns, adaptors and flasks let you build complete, modular setups for distillation, reflux, extraction and purification.

What are the best maintenance practices?
Use glass-compatible detergents, clean using non-abrasive brushes, rinse thoroughly and dry gradually. Store clean ground joints with protective caps to prevent chipping.

What about environmental impact?
Glass is durable and recyclable. The long service life of the parts and the interchangeability of components reduce replacements, supporting more responsible purchasing.
