Cleaning and Maintenance of Bottle-Top Dispenser

The bottle-top dispenser is capable of precise, highly reproducible dispensing without wasting reagents; it provides safety to the operator and the laboratory environment when handling some corrosive liquids or solvents, in addition, it also provides Can withstand high temperature and high pressure, and chemical corrosion. It is widely used in the biological and chemical fields, as well as in clinical medicine, and industrial and commercial laboratories.

Bottle-top dispenser cleaning and maintenance:

1. Clean the glass cylinder.

2. Drain and unscrew the dispenser from the bottle and lift the dispenser up until the drain leaves the surface but is still in the bottle.

3. Carefully tap the drain tube against the inner wall of the bottle to allow the reagent to flow back into the bottle.

4. Press the piston repeatedly to drain the residue back into the bottle.

5. Place the dispenser on another bottle containing the appropriate amount of purified water and rinse the dispenser.

6. Drain the bottle, rinse the bottle, install purified water, and repeat the steps.

7. Drain the dispenser and unscrew the piston seat (A).

8. Carefully remove the piston (O) from the glass cylinder (N). (Note: This can only be done by holding the piston seat).

9. Carefully remove the deposit from the glass cylinder wall with a rag and clean the piston and cylinder with purified water.

10. Insert the piston vertically into the cylinder without tilting and tighten the piston seat.

11. Clean/replace the drain valve/inlet valve.

12. Unscrew the inlet/drain tube (remove the valve lock ring).

13. Unscrew the drain valve/inlet valve with the installation tool, remove the valve and seal the gasket, and do not leave the gasket in the valve.

14. Rinse the drain valve and the inlet valve in purified water and clean them with a soft brush. If the valve ball sticks, use a pointed tool (such as a pipette tip nozzle) to push the inlet of the valve. The valve ball returns to normal use.
