Heathrow Scientific HS20630D Rubber Bulb for Pipette & Syringe, 60ml

Description

Product Overview

The Heathrow Scientific HS20630D rubber bulb is engineered specifically for large‑volume pipettes and syringes used in scientific and industrial laboratories. Constructed from high‑grade rubber, the bulb offers a robust 60 ml capacity while maintaining flexibility and resilience over repeated cycles of compression and release. Its contoured shape, combined with a heavy‑wall neck, creates a natural ergonomic grip that minimizes hand strain and enhances precision when dispensing or aspirating fluids. The bulb measures 2‑1/8″ outside diameter and 3‑1/4″ length, fitting seamlessly onto standard pipette and syringe fittings without the need for additional adapters.

Beyond its core functional attributes, the HS20630D model incorporates a chemically resistant surface that tolerates a wide range of laboratory reagents, including aqueous solutions, organic solvents, and mildly acidic or basic media. The rubber material is also designed to resist cracking, tearing, and permanent deformation, extending the service life of the accessory and reducing the frequency of replacement. Detailed specifications include a product weight of 1.41 ounces, a compact footprint of 4.3 x 3.3 x 3.3 inches, and compliance with industry standards for laboratory pipette accessories.

Usage

This rubber bulb excels in environments where accurate fluid handling is critical. Researchers in biochemistry, molecular biology, and analytical chemistry rely on the HS20630D to transfer precise volumes of reagents, buffers, and samples without introducing air bubbles or inconsistencies. The secure grip provided by the heavy‑wall neck is especially valuable during prolonged protocols such as titrations, serial dilutions, and enzyme assays, where steady hand control directly impacts experimental outcomes.

In addition to traditional laboratory settings, the bulb is well suited for field‑based applications, including environmental testing kits, portable diagnostic devices, and on‑site quality control stations. Its durable construction withstands the rigors of transport and variable temperature conditions, ensuring reliable performance whether used on a benchtop or in a mobile laboratory. The 60 ml capacity also makes it an ideal choice for handling larger sample volumes in cell culture media preparation, reagent mixing, and bulk solution transfers.

FAQ

What types of liquids can the HS20630D rubber bulb handle?

The bulb is compatible with most aqueous solutions, common organic solvents, and mildly acidic or basic reagents. It is not recommended for highly corrosive acids or strong bases that exceed the material’s chemical resistance specifications.

Is the bulb compatible with all pipette sizes?

The HS20630D is designed for large‑volume pipettes and syringes that accept a 1/4″ opening diameter. It fits standard laboratory pipette models from major manufacturers, but users should verify the connector size on their specific instrument.

How do I maintain the rubber bulb for optimal performance?

After each use, rinse the bulb with distilled water and allow it to air‑dry completely. Avoid exposing the bulb to extreme temperatures or direct sunlight, and store it in a clean, dry environment to prevent microbial growth.

Can I use the bulb for sterile applications?

While the bulb itself is not sterile, it can be sterilized using standard autoclave procedures if the rubber material is compatible with the chosen cycle. Always follow your laboratory’s sterility protocols and verify that the bulb’s material can withstand the sterilization method.

What is the warranty period for the HS20630D bulb?

Heathrow Scientific provides a one‑year limited warranty covering manufacturing defects. If the bulb fails due to a defect within this period, we will replace it at no additional cost.
