Description
The Vacuum Adapter with PTFE Stopcock and Straight Connection, BORO 3.3 Glass, also known as a straight vacuum adapter, laboratory vacuum stopcock adapter or glass vacuum control adapter, is designed for connecting compatible laboratory glassware and controlling gas flow during vacuum-related procedures. Manufactured from borosilicate 3.3 glass, the adapter features a straight connection, an integrated PTFE stopcock and one male ground glass cone. Its construction supports convenient integration into compatible laboratory vacuum and gas-handling systems. The PTFE stopcock provides manual control of the connected flow path, allowing users to open, restrict or close the connection as required. PTFE offers resistance to many chemicals commonly encountered in laboratory applications.
The straight connection provides a practical configuration for incorporating the adapter into laboratory glassware assemblies where controlled gas flow or vacuum isolation is required. The adapter is available with 14/20 and 24/40 male ground glass cones, allowing users to select the appropriate joint size for their existing apparatus. Each cone must connect to a matching female ground glass socket. The BORO 3.3 glass construction provides low thermal expansion and resistance to many laboratory chemicals, making the adapter suitable for compatible research, chemical processing and gas-handling procedures. Its transparent glass body allows users to inspect the internal passage and identify visible contamination or damage before installation.
The adapter can be used in laboratory vacuum experiments, controlled gas transfer, chemical synthesis and research applications, provided the complete apparatus meets the required operating conditions. Both variations are supplied individually, with one glass vacuum adapter and integrated PTFE stopcock per pack. Safety Precautions: Inspect the glass adapter and stopcock for damage before use. Support connected apparatus with suitable clamps, verify ground joint compatibility and follow laboratory procedures for handling vacuum equipment. Vacuum Information: The manufacturer does not specify maximum vacuum pressure, stopcock bore size or verified leak-tightness performance. Confirm these requirements before using the adapter in critical vacuum applications.
LabChoice Australia supplies BORO 3.3 vacuum adapters, ground glass connections and laboratory glassware accessories for universities, research laboratories, chemical testing facilities and industrial laboratories across Australia.
