Description
The VWR Straight Vacuum Adapter with a 15/25 upper joint and 14/20 lower joint is a specialized piece of laboratory glassware used to connect a vacuum source to a reaction or distillation assembly.
This configuration serves as a reducing adapter, allowing you to bridge different scales of glassware—specifically connecting larger 15/25 components to smaller 14/20 “microscale” labware.
