Pipette filler bulbs have replaced unsafe mouth pipetting, by introducing a manual liquid aspiration transfer using simple squeezing and releasing action.
Use this rubber bulb pipette filler to safely fill glass and plastic pipettes. The three‐valve design allows
you to release air, draw liquid into the pipette and accurately release liquid. It works with all sizes of
Mohrs, serological, or Bulb pipettes, except for 1ml and smaller plastic pipettes.
Operation
- Insert the top of the pipette in the bottom.
- Release air from the pipette filler by squeezing valve “A” on the top while simultaneously squeezing the bulb. The amount of air you release is dependent on the size of the pipette you are using— release more air for larger volume pipettes.
- Insert the tip of the pipette into the liquid to be dispensed.
Be careful not to draw liquid into the pipette filler.
- Empty the pipette by squeezing valve “E” on the side‐tube. This allows you to release liquid at the desired rate and to the desired level.
- It works best to fill the pipette past the zero mark on step 4 (valve “S”) and then draw the level down to the zero mark on step 6 (valve “E”). Once the pipette is filled to the level desired the contents can be dispensed using valve “E”.
Description
- The rubber bulb pipette filler is used to safely draw liquids into a pipette.
- One valve releases air, another draws in liquid, and the third regulates and releases the liquid.
- Made from natural rubber material
- Will accommodate pipettes up to 50ml
- Features a 1/4-inch diameter opening
- This filler eliminates the need for dangerous mouth pipetting.
- They are available in red colour
Capacity
- 50ml
How to use:
- Insert the top of the pipette in the bottom of the pipette filler.
- Release air from the pipette filler by squeezing valve on the top of the pipette filler while simultaneously squeezing the bulb. The amount of air you release is dependent on the size of the pipette you are using-release more air for larger volume pipettes.
- Insert the tip of the pipette into the solution to be dispensed.
- Siphon solution into the pipette to the desired level by squeezing valve on the bottom of the pipette filler.
- This uses the vacuum created in the bulb to draw solution into the pipette. Avoid to draw solution into the pipette filler.
- Empty the pipette by squeezing valve on the side tube. This will help to release solution at the desired rate and to the desired level.
- It works best to fill the pipette past the zero mark on step D and then draw the level down to the zero mark on step F. Once the pipette is filled to the level desired the contents can be dispensed using the bottom valve.
