This bulb-type safety pipette filler is designed for efficient one-hand operation. Made from natural rubber for better memory and resistance to chemical attack.
Its three glass valves control the evacuation of air, liquid uptake and liquid dispensing. Expel air from the bulb by squeezing the "A" valve and the bulb at the same time. Draw liquid into the pipette by squeezing the "S" valve. To dispense liquid, squeeze the "E" valve. To deliver last drop squeeze the small bulb next to the "E" valve.
