Pipette Filler is a precision-engineered bulb-type device designed for safe, hands-free filling and dispensing of liquids with standard laboratory pipettes. It eliminates the hazards of mouth pipetting while ensuring clean, accurate, and controlled liquid handling. Widely used in research, education, QC/QA, and industrial laboratories, it provides smooth operation through its three-valve control system, making daily pipetting fast, reliable, and contamination-free.
Key Features
- Three-Valve Operation (A, S, E): Ensures controlled air release, filling, and liquid dispensing.
- Hands-Free, Safe Pipetting: Prevents direct contact with hazardous chemicals, biological samples, and corrosive reagents.
- Smooth & Consistent Flow: Stainless steel valve balls ensure precise uptake and controlled delivery.
- Ergonomic Bulb Design: Requires minimal pressure for suction and enhances comfort during repetitive tasks.
- Durable & Chemical-Resistant: Suitable for routine use in academic, industrial, and pharmaceutical environments.
- Fits Standard Pipettes: Compatible with most glass and plastic serological pipettes.
Material Specifications
Silicone Rubber (Option)
- High elasticity and excellent recovery after repeated squeezing
