Medicine Droppers, Pipettes, and Bulbs
C211. Bulb, rubber, 1 mL capacity. Spare rubber bulbs for medicine droppers. Will also work with Pasteur pipettes but will not draw the full volume of a standard Pasteur pipette.
#C211.............$3.00 / dozen
C212. Bulb, rubber, 5 mL capacity. Pipette bulb, mainly for use with dropping pipets.
These work with the Volumetric pipettes; instead of putting the end of the pipette into the hole in the bulb, press the end to the hole to make a seal when drawing up liquid. This takes practice but makes it easier to remove the bulb quickly-- before the liquid drops below the fill line.
Hole is of a small diameter, ca. 2 mm. Even with stretching, it's too narrow for Pasteur pipettes. (When we use these ourselves in the lab, we enlarge the hole).
Color: black
Sold in quantity of 1 dozen each.
