A Physical and Chemical Research manufacturer use two types of Spanclamps Fasteners on an evaporator which extracts particular solvent from the sample liquid.
Multiple vials with liquid are set in the holder to evaporate, and the vial holder is removed from the evaporator after evaporation, but the vial holder reaches high temperatures up to 100°C. That's why they use Spanclamps Ball-Locking Push-Push for a detachable knob. Finger-operative shape and ball lock mechanism enable quick and secure changeover operation of the vial holder.
In addition, they use Spanclamps Quarter Turn to fix the plug holder that plugs into whole vials at once. Just a quarter turn of the knob enables locking/unlocking the plug holder and allows easy changeover.
The vial holders should be replaced after each experiment and the plug holders should be replaced every time the size of the vial changes, so customers are satisfied with one-touch changeover.
