Item detailsMaterials, dimensions, what is in the box
Rubber pipette bulb construction in natural rubber gives you a hand-operated way to draw solution into a pipette. This red pipette filler uses elastic suction and three valves for laboratory liquid handling. Its molded body measures 5.1 × 2.4 × 2.4 inches, making it a separate suction accessory used with a pipette.
Squeeze the flexible body by hand and use the three valves to operate the suction mechanism. The solid-colored surface has visible molded seams and raised valve letters. This manual design is intended for drawing solutions in industrial, mineral, agricultural, food, and chemical laboratories.
Choose the red option for a single rubber suction bulb. When setting up your workspace, allow for the bulb's overall dimensions as well as the separate pipette you use with it. For storage, keep the bulb at least 59.1 inches from heat sources. The package contains one bulb for your liquid-handling setup.

What problem does it solve?
Draw solution into a pipette with a hand-operated suction accessory. This manual pipette filler gives you a flexible rubber body and three valves to operate during laboratory liquid transfer.
The problem in numbers
A historical laboratory-infection study attributed approximately 13% of infections to mouth pipetting. (Ulster Medical Journal, review of Pike's historical research, 2021)
Pike's historical analysis examined 3,921 laboratory-associated infection cases. (Ulster Medical Journal, reference to Pike's 1976 analysis, 2021)
A laboratory-biosafety review estimated that 500,000 US laboratory workers were at risk of exposure to infectious agents. (Clinical Microbiology Reviews, 1995)
These historical figures concern laboratory exposure, not household outcomes or measured performance of this bulb. A hand-operated filler provides a way to draw solution using rubber suction rather than mouth suction, within an appropriate laboratory procedure.
Why choose this one?
Choose natural rubber construction with a three-valve design and raised valve letters. This pipette suction bulb brings those concrete features together in a single red, hand-squeezed accessory.
What exactly do you get?
You receive one red rubber suction bulb measuring 5.1 × 2.4 × 2.4 inches overall. Use the filler bulb with a separate pipette to draw solution by elastic suction.
