Design: This schlenk tube is designed with a heavy-wall cylindrical tube with an outer ground joint on top and a high vacuum valve at the side arm. The outer joint on top can be used to attach a jointed lab glassware apparatus for adding or transferring materials. The high vacuum valve at the side arm allows for the exchange of the atmosphere of the flask with inert gas and enables counterflow or sampling operations.
Use: This schlenk tube is perfect for storage or running small reactions in air-sensitive chemistry. The high vacuum valve allows for a highly sealed system, which is essential in air-sensitive reactions. The side arm can be used to connect to a vacuum line for purging and flushing with inert gas.
Dimensions: This schlenk tube comes with a 0-4mm or 0-8mm high vacuum valve with a PTFE O-ring at the tip and PTFE wiper to protect the O-ring on the shaft. It has a capacity from 10mL to 1000mL.
Heavy wall: This schlenk tube is hand-blown according to ASTM E438 and made of high-quality borosilicate glass, which is annealed at 800 degrees Celsius. It can be heated directly in an open flame and can withstand typical laboratory thermal variations. It is durable and reusable.
