The Wincom 2 Fixed Amount Absorbs Ball (commonly known as a Fixed-Volume Rubber Suction Bulb or Pipette Filler) is a specialized liquid handling utility designed to draw and dispense precise, pre-measured amounts of fluids without manual measurement errors. Outfitted with a high-elasticity rubber chamber and dual-valve technology, it provides strong, controlled suction. This tool completely eliminates the dangerous practice of mouth-pipetting, offering a safe, hygienic, and highly efficient solution for transferring volatile chemicals, acids, and biological samples across laboratory environments.

Technical Specifications

• Equipment Type: Fixed-Volume Dual-Valve Rubber Suction Bulb

• Material Composition: High-density, natural vulcanized rubber or premium silicone alloy

• Control Valve Architecture: 2 independent mechanical valves (Air release and Suction/Dispense control)

• Volumetric Calibration: Designed for rapid connection to specific fixed-amount volumetric pipettes

• Fitting Interface: Universal tapered neck neck ring that seals tightly around standard glass or plastic pipettes

• Resiliency Metrics: Highly resistant to elastic fatigue and chemical vapor cracking

• Color Configuration: Standard laboratory high-visibility red or black safety finish

Key Features

• Precise Dual-Valve Suction Loop: Features two separate mechanical control valves that allow the operator to evacuate air from the main bulb and pull or release fluids with simple fingertip pressure.

• 100% Mouth-Pipetting Prevention: Provides a physical vacuum barrier that completely protects laboratory technicians from accidentally inhaling toxic chemical vapors, corrosive acids, or hazardous biofluids.

• High-Elasticity Heavy-Gauge Rubber: Molded from natural vulcanized rubber that snaps back to its original circular form instantly, ensuring consistent, high-power suction torque even after thousands of cycles.

• Liquid-Tight Universal Seal: The intake nozzle features a thick, highly flexible inner collar that stretches easily over various pipette diameters, creating a vacuum-tight seal that prevents fluid leaks.

• Ergonomic One-Handed Operation: The lightweight, contoured round profile fits comfortably in the palm of the hand, reducing finger fatigue during high-repetition liquid dispensing and routine analytical titrations.

Primary Applications

• Clinical Chemistry and Assays: Drawing and moving exact volumes of standard acids, bases, and buffer solutions during routine sample analysis.

• Microbiology and Media Preparation: Transferring measured amounts of sterile nutrient broths, culture liquids, and liquid reagents inside safety hoods.

• Industrial Quality Testing: Sampling raw liquid chemicals, industrial wastewater portions, and solvent mixtures safely away from skin contact.

• Educational Academic Labs: Training school and university science students on proper, safe liquid handling techniques and standard titration mechanics.
