Reaction/Schlenk Tube 100ml With 14/20 Outer Joint And 0-4mm High Vacuum Valve At Side Arm
Special Price $30.89 Regular Price $47.80
- DESIGN----This schlenk tube is comprised of a heavy wall cylindrical tube which is very convenient for magnetic stirrer during reaction.With 0-4mm high vacuum valve having PTFE o-ring at tip and PTFE wiper to protect the O-ring and shaft.With a standard taper joint on the top of tube attaching to lab glassware for adding ,transferring or reflux.
- USE---The schlenk flask with high vacuum valve is usually used as a storage flask or reaction flask in air-sensitive chemistry with high sealing performance.The high vacuum valve at top is not only used to control the liquid or gas flow,but also can be removed off to add or transfer materials.For a reaction setup, this flask is used to conduct reactions at elevated pressures and temperatures as a closed system.
- DIMENSIONS----This round bottom flask is designed with 0-4mm high vacuum valve on side-arm ,with 14/20 standard taper outer joint,which can be stopped by a 14/20 glass topper or 14# rubber septum.Capacity of 100mL
- HEAVY WALL ---This schlenk tube is heavy-wall designed , made by hand-blowing according to ASTM E438 ,made of high-quality borosilicate glass and annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling,durable and reusable.
This schlenk tube is with an outer ground joint on Top ,a high vacuum valve at side which can be used to exchange the atmosphere of the flask is to flush the flask out with an inert gas.and the Counter flow or sampling operations can easily be made by purging through the sidearm and removing the plug. These are great for storage or for running small reactions.
Laboy glass flasks are heavy wall designed,made by hand-blowing to ensure uniform wall thickness, made of high-quality borosilicate glass and annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.
