Frequently Asked Questions
How does the three-valve design work?
Each glass ball valve controls a distinct function. Press the top valve to evacuate air, the side intake valve to aspirate liquid, and the lower valve to dispense — all manageable with one hand for steady flow control.
What pipette types does this filler fit?
The rubber nozzle accommodates standard glass and plastic serological and volumetric pipettes. Insert the pipette firmly into the bulb opening to form a secure seal before drawing liquid.
Is this pipette filler autoclavable?
Natural rubber bulbs are not recommended for repeated autoclaving, as heat degrades the elastomer and glass valves. Wipe externally with compatible disinfectant and inspect valves regularly for wear.
How is this product sold?
SKU PWY145 ships as 1/each at $28.10 per unit. Volume and institutional pricing tiers are available for departments standardizing on a single filler across multiple benches.
