Quick Start Manual of Hawach Bottle-Top Dispensers

Firstly, let’s divide those bottle-top dispensers into 3 groups according to their materials

A. Highly corrosion resistant materials such as PTFE, PFA, boron silicate, platinum, etc.

Application: Resistant to high-temperature sterilization (121℃), withstand most of the acid, alkali, organic and inorganic solvents; can be fine-tuned for different solvent physicochemical properties; three-function valve’s standard configuration recirculation function can avoid solution Waste, and unique wiper seal ring effectively reduces piston expansion and crystallization.

B. Made of ETFE, FEP, PFA, PP material

Applicable to general acid and alkali and low concentration of strong acid and alkali and salts, such as H3PO4, H2SO4, NaOH, KOH, etc.
Maximum pressure 500 bar, maximum viscosity 500mm2/s, maximum temperature 40°C, and maximum liquid density is 2.2g/cm3. Easy to calibrate.

C. Almighty / hydrofluoric acid dispenser

Suit for hydrofluoric acid, strong acid, nicotinic acid, alkali, solvent, and extremely dangerous liquid. Integrated PTFE structure, no spring structure in drain valve, no corrosion and metal ion contamination reagents, suitable for trace analysis. Avoid leakage of niacin/odorous chemical liquid odor with a safety valve.

We can also divide bottle-top dispensers into two big categories, one for biological laboratories and biological use. One for chemical, chemical engineering, trace analysis, and harsh environments.
