Description
Precision Flow Control for Microscale Vacuum Applications
Upgrade your manifold or air-sensitive reaction setups with the Chemglass CG-1049-J-30 Vacuum Adapter. Expertly engineered for microscale laboratory applications, this specialized adapter seamlessly bridges standard taper glassware with threaded components while providing precise isolation and flow control.
This adapter features a 7/10 standard taper outer joint on one end and a 20-400 GPI threaded connection on the other. At the center of the adapter is a high-quality PTFE (Teflon) stopcock, which allows for the smooth, grease-free regulation of vacuum or inert gas flow. Manufactured from heavy-wall borosilicate glass, it ensures the chemical inertness and durability required for rigorous daily use in organic and Schlenk line chemistry.
Key Features & Benefits
- Grease-Free PTFE Stopcock: The chemically inert Teflon stopcock plug will not freeze and requires no vacuum grease, preventing sample contamination while offering fine control over gas or vacuum flow.
- Dual-Connection Versatility: Seamlessly connects microscale 7/10 inner joint glassware to 20-400 GPI threaded vials, tubes, or caps.
- Air-Sensitive Chemistry Ready: Ideal for isolating sensitive microscale reactions, degassing solvents, or connecting specific apparatus to a Schlenk line.
- Durable Borosilicate Construction: Crafted from high-quality, low-expansion borosilicate glass to withstand harsh chemical environments and vacuum pressures.
