The Lenz-Laborglas Spiral Condensers, Socket/Cone NS 29/32 Jacket L.mm 400 are designed for efficient condensation during laboratory distillation and reflux operations. Constructed from high-quality borosilicate glass, these condensers offer excellent resistance to thermal shock and chemical corrosion. The spiral design provides a large surface area for effective heat exchange, while the NS 29/32 socket and cone ensure secure and leak-free connections with other laboratory glassware. The 400 mm length offers a good balance between performance and space efficiency in lab setups.
The Lenz-Laborglas Spiral Condenser is ideal for laboratories needing efficient condensation with durable, high-performance glassware.
