2. Slide the moving part up against the test tube so that it is held securely and tighten the
thumb-screw.
Do not over-tighten.
3. Remove the test tube and re-insert it without adjusting the thumb screw.
The slide is locked down on only one side so it serves as a spring. If the tube is held
securely and slides in and out with ease the tension is correct. If significant force is
required to insert or remove the tube, or if the tube wobbles while in place, adjust the
position of the slide component to decrease or increase the grip tension as required.
