PIPETTE FILLER BULB TYPE

 Product Description
The Pipette Filler (Bulb Type) is a manual, rubber-based liquid handling accessory designed to provide safe and precise control over the aspiration and dispensing of liquids using pipettes. It is shaped like a bulb and typically includes one-way valves or a three-valve mechanism (Aspirate, Dispense, and Air Release) to regulate fluid movement. This tool eliminates the hazardous practice of mouth pipetting and ensures user safety when working with corrosive, toxic, or infectious substances. Compatible with both glass and plastic pipettes, the bulb-type pipette filler is widely used in educational, clinical, pharmaceutical, and analytical laboratories.

Uses
Primary Uses
Laboratory and Clinical Applications

• Drawing up and releasing accurate volumes of liquid into and from pipettes. 
• Used in titration, reagent handling, and sample preparation in chemistry labs. 
• Essential in pathology and diagnostic labs for transferring biological samples. 
• Ensures contamination-free handling of hazardous or sterile liquids. 
• Compatible with volumetric, graduated, serological, and Pasteur pipettes. 

Secondary Uses
Educational and Research Settings

• Teaching students proper, safe pipetting techniques in school and college labs. 
• Assisting in sample handling and preparation in biochemical and microbiological research. 
• Employed in research labs where precision fluid transfer is critical. 

Key Attributes
