A Natural Rubber Pipette Filler (often called a "propipette" or 3-way bulb) is a standard laboratory safety tool used to aspirate and dispense liquids without mouth contact. These bulbs are preferred for their flexibility, chemical resistance, and cost-effectiveness in routine lab work.
Key Features
- Material: Made from flexible, durable red natural rubber.
- Capacity: Universal design typically accommodates pipettes from 1 mL to 100 mL.
- Standard Configuration: Features a 3-valve "pinch-and-release" system for precise control.
- Compatibility: Fits most standard glass and plastic volumetric or graduated pipettes.
The 3-Valve System (A-S-E)
Most natural rubber fillers use the standard three-valve layout for one-handed operation:
- Valve A (Air): Located at the top; pressed while squeezing the main bulb to expel air and create a vacuum.
- Valve S (Suction): Located on the stem; pressed to draw liquid up into the pipette.
- Valve E (Empty): Located on the side arm; pressed to release or dispense liquid in a controlled manner.
Safety and Maintenance Tips
- Avoid Over-insertion: Insert the pipette only a few millimeters to form a seal; pushing too far can dislodge internal valves.
- Prevent Ingress: Never allow liquid to enter the bulb itself, as this can cause contamination or damage the rubber.
- Cleaning: Rinse with distilled water after use, especially if handling corrosive substances.
- Storage: Keep in a cool, dry place away from direct sunlight to prevent the rubber from cracking over time.
