Screw-Cap Tubes
The Screw-Cap Tube is commonly used in sample degasification. The vacuum quality that it can maintain is >10-4 torr. For better vacuum, please check our Pressure/Vacuum Tube and Quick Pressure Valve Tube. Each Screw-Cap Tube comes with one PTFE/Silicone Septum.
Note:
PTFE/ Rubber septums are inert to most solvents and many corrosive materials but not recommended for multiple punctures.
PTFE/Silicone septums are inert to most organic solvents and compounds but not recommended for strongly corrosive materials. The septum remains reliable after multiple punctures.
