All wetted components are made of PTFE,FEP, PFA and borosilicate glass and are therefore extremely resistant to chemicals. The springless PTFE valve block ensures excellent chemical resistance and leak-free operation. In addition, this enables a wiper-like movement of the piston, making it suitable for all crystalline liquids. High accuracy, fatigue-free, smooth piston movement possible without high force thanks to PTFE piston and Viton O-ring. The dosing cylinder is protected against breakage by a polypropylene sleeve. In the event of accidental breakage, the sleeve prevents the spread of glass splinters. The large volume scale printed on both sides of the dispenser body allows the volume to be read quickly, effortlessly and accurately.The adapter can be rotated 360° on the neck of the bottle so that the liquid can be dispensed in the desired direction.
