Test Tube holder with space for Schlenk / Straus vent

This holder is made for test tubes with a diameter of about 18mm. Schlenk / Straus vents can be aligned to the top, limiting rotation as much as possible while it is mounted inside the holder. The test tube is mounted at a 45° angle. And there are “windows” made from all directions making it much easier to see what you are working with while the tube is placed. 

This version is optimal for tubes with a length of about 7.5cm from the bottom of the tube to the start of the Schlenk / Straus vent.

The mount moves the center of mass downwards, making the tube much more stable, and it is much harder for it to fall over, which is especially ideal in an environment where you have limited space or within a glovebox.
