What Lenz Laborglas does

Lenz Laborglas GmbH & Co. KG is a privately held German manufacturer of laboratory glass apparatus headquartered in Wertheim, Germany. The company was founded in 1930 and has been operating continuously for over 90 years under family ownership; Stefan Lenz and Susanne Eberhard serve as the authorized managing directors (Vertretungsberechtigte Geschäftsführer). It employs between 101 and 250 people and is structured as a German GmbH & Co. KG limited partnership, registered in the Mannheim commercial register under HRA 570191.

The company produces a catalog of over 10,000 standard laboratory glass instruments manufactured primarily from DURAN® borosilicate tubing, spanning ground joints (Schliffe), stopcocks (Hähne), flasks (Kolben), separating and dropping funnels, chromatography columns, distillation components and condensers, extraction apparatus (Soxhlet, Twisselmann, Knöfler-Böhm and others), general laboratory accessories, and complete reaction vessel systems with thermostatic jackets, vacuum jackets, flat flange lids, stirrers, stirrer bearings, and support structures. The company positions itself as a "Schliffgerätespezialist" (specialist for ground joint apparatus) and additionally offers custom manufacturing of individual solutions to customer drawings. Notable technical specifications include vacuum-tight stirrer bearings rated to 10⁻³ mbar at continuous operation up to 800 rpm.

Lenz Laborglas generates revenue through B2B direct sales of standardized and custom-manufactured laboratory glass products to enterprise customers across chemical, pharmaceutical, petrochemical, food, biotechnology, and academic/research verticals, with global reach. The company uses an enterprise field sales motion supported by trade show participation (analytica 2026 in Munich, LAB Supply 2026 in Vienna), downloadable product catalogs, and a tri-lingual (German, English, French) corporate website.
