360°-turn for your added safety: No matter how much you tighten LABMAX airless HF, you can always redirect the discharge tube by simply turning the valve block to the desired position. This way the label of the bottle is always visible. This feature works for all our adapters. Adapters for different bottle threads can stay on the bottle!
100% drip-free system for your safety: By turning the discharge tube at 180° all liquid flows back into the bottle. LABMAX airless HF is completely closed and no accidental discharge can occur by inadvertently moving the piston. There is absolutely no dripping possible!
Automatic air-purging:Â To ensure accurate volume it is necessary that the device is free from air before dispensing. All LABMAX airless HF models have an automatic air purging system. Air, lighter than liquid, passes off the device automatically through the special ejection channel and discharge tube. A contamination of the bottle content is not possible.
The components having direct contact with the reagent are made of chemical resistant materials: platinum spring, ceramic valve balls, PTFE piston, borosilicate glass 3.3 cylinder, borosilicate glass 3.3 valve
