Bottle-Top Dispensers

Basically, all the solvents in the lab can use bottle-top dispensers that have the features of high safety and accurate quantification.

1. The basic bottle-top dispenser

The basic bottle-top dispenser is suitable for a wide range of reagents, including general acid, alkali and salt solutions, lower concentrations of non-oxidizing strong acids and strong bases and polar organic solvents (excluding non-polar organic solvents and halogenated hydrocarbons, etc.).

This kind of bottle-top dispensers: the maximum proof pressure 500 m bar; the maximum solution viscosity 500mm2/s; the biggest solution heat resistance 40 ℃; the maximum liquid density 2.2 g/cm3.

2. The organic bottle-top dispenser

The organic bottle-top dispenser is suitable for a wide range of organic solvents and a higher concentration of the strong acid solution. This kind of bottle-top dispensers: the maximum proof pressure 500 m bar; the maximum solution viscosity 500mm2/s; the maximum liquid density 2.2 g/cm3.

3. The hydrofluoric acid bottle-top dispenser

It is applicable to HF solution only. Ceramic pistons are used because HF corrodes the glass, and the reagent bottles should be plastic. This kind of bottle-top dispensers: the maximum proof pressure 500 m bar; the maximum solution viscosity 500mm2/s; the maximum liquid density is 3.8 g/cm3.
