EISCO Pipette Filler, Rubber Bulb – 54mm Dia. Three Pinch Valves – Suitable for Noxious Solutions Labs

Description

Product Overview

The EISCO Pipette Filler Rubber Bulb is engineered for laboratories that routinely work with toxic, corrosive, or biologically hazardous liquids. Crafted from high‑grade rubber, the bulb offers a soft yet resilient feel that minimizes hand fatigue during repeated suction cycles. Its 54 mm diameter provides ample volume for rapid aspiration while maintaining a compact profile that easily attaches to standard pipettes. The three pinch‑valve system—two for controlling influx and one for efflux—delivers precise regulation of liquid movement, allowing users to draw, dispense, and vent without cross‑contamination. Detailed specifications include a 6 × 4 × 4 inch package size, a lightweight 1.28 oz net weight, and a robust construction that resists chemical degradation. The product is identified by GTIN 00849230025571 and UPC 849230025571, ensuring traceability across supply chains.

Usage

Designed for a wide range of laboratory applications, this rubber bulb excels in environments where safety and precision are paramount. Researchers handling noxious solutions, microbial suspensions, or volatile reagents benefit from the secure seal that prevents accidental leaks and exposure. The bulb’s ergonomic shape fits comfortably in the hand, making it suitable for prolonged use during titration, serial dilutions, or sample preparation. Its three‑valve configuration allows simultaneous control of multiple fluid pathways, which is especially useful in protocols that require alternating between aspiration and dispensing without removing the pipette from the workbench. The filler is compatible with most standard pipettes, including glass and plastic models, and can be integrated into automated or semi‑automated workflows where manual suction is still required.

FAQ

What types of liquids can I safely use with this rubber bulb?

The bulb is designed for a broad spectrum of laboratory liquids, including acidic, basic, organic solvents, and microbial suspensions. Its rubber composition resists most chemicals commonly encountered in research settings, but users should consult material compatibility charts for highly aggressive reagents.

How do the three pinch valves function during pipetting?

Two of the valves control the influx of liquid into the pipette, allowing you to draw samples with minimal effort. The third valve manages efflux, enabling precise dispensing or venting of air. By pinching the appropriate valve(s), you can independently regulate suction and release without removing the pipette.

Is the bulb compatible with both glass and plastic pipettes?

Yes, the bulb’s universal fitting is engineered to attach securely to standard glass and plastic pipettes. Its flexible rubber material creates a tight seal on a variety of tip diameters, ensuring consistent performance across different pipette models.

Can I replace the bulb if it becomes worn or damaged?

Absolutely. EISCO offers replacement bulbs that match the original specifications. Contact our support team with the model number CH0580A, and we will provide the appropriate part along with guidance on installation.
