The Use Method And Precautions Of Bottle Dispenser

Bottle-top dispensers, also known as bottle-top dispensers and bottle-top pipettes, are instruments for accurately measuring liquid medicines. Generally divided into automatic bottle-top dispensers, continuous bottle-top dispensers, glass dispensers, bottle-top dispensers, bottle-top dispensers, digital dispensers, vernier dispensers, standard dispensers , Organic type dispenser, hydrofluoric acid type dispenser. It is widely used in biological and chemical fields, as well as clinical medicine, industrial and commercial laboratories.

How to use bottle dispenser

1. Insert the liquid inlet pipe and tighten the nut.

2. Insert and tighten the drain tube.

3. Open the cap and place the removed cap under the drain tube.

4. Adjust the dispensing volume from zero to the corresponding value through the rotating scale.

5. Exhaust process: make sure that the cover of the drain pipe is open, lift the piston for a certain distance, then press it down, repeat this step 1-2 times, and stop when the bubbles are completely eliminated through the observation window.

6. After exhausting, start preparing for liquid dispensing. (Note: If the exhaust has not been completely exhausted, please check whether the suction pipe or other valves are installed correctly.)

7. Adjust the dispensing volume from zero to the corresponding value through the rotating scale.

8. After use, first press the piston to the bottom, and then adjust the knob to zero scale to lock the bottle dispenser.

9. Pipetting process: Lift the piston steadily to the highest point, and then press it to the bottom steadily, thus completing a dispensing process.

Precautions for bottle-top dispensers

1. When installing the discharge pipe and the inlet pipe, insert the pipe port straight into the valve and tighten the nut to avoid violent installation and damage the pipe port.

2. Before each use, it must be ensured that the inlet valve, the discharge pipe and all the valves are correctly installed and tightened to prevent the piston from splashing.

3. Drain the liquid so that the drain pipe is not directly facing the operator to ensure safety.

4. Control the piston to move slowly and uniformly when discharging, use a suitable container to receive it, and let the liquid fall down the wall.

5. Please stop immediately when you encounter any failure during liquid discharge, and do not operate violently to avoid further damage to the instrument.

6. After using the instrument, please buckle the safety cap of the drain tube to prevent the liquid at the drain tube mouth from dripping due to gravity or absorbing water vapor in the air.

7. After using the instrument, please rotate the scale adjustment ring to the "0" position to ensure safety.

8. Prohibited reagents: HF acid and bromine suspension. (If used, a special bottle-top dispenser is required)

9. Do not stain organic reagents on the surface of the instrument. If it does, wash it off with water in time.

10. The suitable temperature for the operation of the bottle-top dispenser is 4-50℃.
