The Classification of Bottle-top Dispenser
Bottle-top dispensers are mainly divided into three types: basic type, organic type, and hydrofluoric acid type.
The basic type is suitable for a wide range of reagents, including general acid-base solution, low concentration of non-oxidized strong acid-base and polar organic solvents (excluding non-polar organic solvents and halogenated hydrocarbons), such as H3PO4, HCl, H2SO4, NaOH, NaCl, etc. Zui has a high-pressure resistance of 500 Mbar, a high viscosity resistance of 500 mm2/s, high-temperature resistance of 40 and a high density of 2.2 g/cm3.
Organic type is suitable for a wide range of organic solvents and high concentration of strong acid solutions, such as chlorine-containing fluorine-containing organic solvents, trifluoroacetic acid, tetrahydrofuran, peroxide, chloroform, HNO3, etc. Zui has a high-pressure resistance of 500 Mbar, a high viscosity resistance of 500 mm2 / s and a high liquid density of 2.2 g/cm3.
Hydrofluoric acid type is only suitable for HF solution. Because HF corrodes glass, the piston of the distributor is a ceramic piston, and the suitable reagent bottle should be plastic material Zui with high pressure 500 Mbar, Zui solution with high viscosity 500 mm2/s and Zui with high liquid density 3.8 g/cm3.
