The bottle top dispenser is the instrument for measuring liquid reagents. It is widely used in the fields of biology and chemistry, as well as clinical medicine, production laboratories etc, due to its reliability in safety, convenient operation and precise calibration.
The bottle-top dispenser is fixed on the reagent bottle through a screw-top valve, closed tightly and firmly, so that the solution transfer process is in a closed system, avoiding the volatilization, splashing, and everturning of the solution, and reducing the environmental and human hazards. It is much safer than the completely open pipetting process of the measuring cylinder.
How to use bottle-top dispenser
- Insert the liquid inlet pipe and tighten the nut.
- Insert the drain tube and screw it tightly .
- Open the cap and put it under the drain tube.
- Adjust the dispensing volume from zero to the corresponding value through the rotating scale.
- Exhaust process: make sure that the cover of the drainpipe is open, lift the piston for a certain distance, then press it down, repeat this step one to two times, and stop when the bubbles are completely eliminated through the observation window.
- 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.)
- Adjust the dispensing volume through the rotating scale.
- After use, first press the piston to the bottom, and then adjust the knob to zero scales to lock the bottle dispenser.
- Pipetting process: lift the piston steadily to a higher place, and then press it to the bottom steadily, thus completing a dispensing process.
