Products from Lenz-Laborglas GmbH & Co. KG – High-Precision Laboratory Glassware for Research and Process Optimization

Lenz-Laborglas GmbH & Co. KG has been a trusted name for decades, offering premium laboratory glassware made from DURAN® glass, borosilicate glass 3.3, and advanced materials such as PTFE. At häberle LABORTECHNIK, professionals in research, quality assurance, and the chemical-pharmaceutical industry will find a comprehensive selection tailored precisely to the demands of modern laboratories.

Laboratory Glass Instruments for Analytical Precision and Process Safety

Lenz provides a wide range of glass apparatus and components known for their chemical resistance, mechanical durability, and thermal stability.

Examples include:

Dropping funnel with pressure equalizer (e.g. 50 ml, NS 19/26, PTFE stopcock )
Ground joint lid (e.g. DN 200, MH NS 45/40)

These components enable safe execution of complex chemical reactions and allow for modular system expansion.

Glass Equipment for Reactions, Distillation, and Extraction

The product range supports essential laboratory applications:

Distillation heads, bent 105°
Vacuum adapters with threaded or socket connections
Soxhlet extraction apparatus, 150 ml, NS 45/40

Specialized condensers provide optimal temperature control:

Intensive condensers with plastic olives
Coil condensers with glass olives
Allihn and Davies condensers for reflux and extraction processes

Connection Components: Adapters and Stopcocks

Flexible connection solutions include:

Bent adapters, 90°, with or without stopcock
Straight adapters
Variants with NS sockets, DURAN® tubing, or PTFE stopcocks
Stopcocks for desiccators made of borosilicate glass 3.3

These elements ensure safe, standardized integration within laboratory setups.

Technical Accessories for Advanced Reaction Systems

Special components for large-scale setups and precise measurements:

Double-blade stirrer, PTFE/steel for 30,000 ml vessels
Temperature sensor Pt 100, NS 14/23
Complete stand system for LF 200 – approx. dimensions W 1.0 × D 0.5 × H 2.0 m

These solutions support reliable control, measurement, and integration into laboratory processes.

Industry Trends: Standardization, Modularity, and Chemical Resistance

Recent developments in lab glass manufacturing are driven by:

Increased modularity for flexible laboratory workflows
Durable, chemically resistant materials like DURAN® glass and PTFE
Consistent standardization (e.g., NS 14/23, NS 29/32) for system-wide compatibility

These trends enhance safety, process efficiency, and investment value in modern laboratories.
