OPTIFIX SOLVENT is available - for dispensing solvents and viscous media. The glass plunger of the dispenser is ground into the clear glass cylinder to give a precise fit so that liquids with a viscosity of about 100 m / s (e.g. oil) can be dispensed. No metal springs are used in the SOLVENT dispenser. The sample liquid is free of metallic ions. The finger guard of the SOLVENT is red so as to avoid mistakes. The OPTIFIX SOLVENT dispensers are offered in nine sizes from 0.4 ml up to 500 ml.
