Heathrow HS20622B Latex Dropper Bulbs 2 mL Pack of 72 Easy-Attach

Description

Product Overview

The Heathrow HS20622B latex dropper bulbs are engineered to provide consistent, leak‑free fluid handling for a wide range of laboratory applications. Constructed from high‑quality natural rubber latex, each 2 mL bulb offers a smooth, pliable surface that conforms to the pipettor tip while maintaining precise volume control. The bulbs are designed for easy attachment to standard pipettors, eliminating the need for additional tools or adhesives. Packaged in a compact box of 72 units, the set ensures that laboratories, teaching facilities, and quality‑control stations have a ready supply of reliable dropper accessories. Dimensions of each bulb are optimized for ergonomic handling, and the lightweight construction (approximately 1.76 oz per pack) reduces the overall load on pipetting equipment, extending the lifespan of both the pipettor and the bulb. The product meets rigorous industry standards, reflected in its favorable customer rating of 4.1 stars from 25 reviews and its ranking among top lab pipettor accessories.

The natural rubber latex used in these bulbs is sourced from certified plantations that follow sustainable harvesting practices, ensuring both environmental responsibility and material consistency. Each bulb undergoes a multi‑stage quality‑control process that includes tensile strength testing, burst pressure verification, and dimensional accuracy checks. This thorough validation guarantees that every unit performs reliably under the demanding conditions of modern laboratories. The packaging includes clear labeling of model number HS20622B, volume capacity, and safety instructions, facilitating quick identification and compliance with laboratory safety protocols. Additionally, the product’s compact footprint allows for efficient storage in laboratory cabinets, reducing clutter and improving workflow organization.

Usage

These latex dropper bulbs are ideal for precise dispensing of liquids in chemistry, biology, and environmental testing workflows. Whether measuring reagents for titration, delivering culture media to cell plates, or sampling environmental water, the 2 mL capacity provides enough volume for most routine tasks while allowing fine‑tuned control for micro‑volume applications. The flexible, easy‑attach design enables rapid swapping between different pipettors, minimizing downtime during multi‑step protocols. Users in academic labs can benefit from the cost‑effective bulk packaging, ensuring that each student has access to a fresh, uncontaminated bulb for every experiment. In industrial settings, the bulbs’ durability reduces the frequency of replacement, supporting continuous operation on production lines that require accurate fluid transfer. Compatibility with standard pipettor models means that the bulbs can be integrated into existing workflows without the need for equipment upgrades.

For optimal performance, it is recommended to pre‑wet the latex bulb with the intended solution before the first use. This practice helps to eliminate air bubbles and ensures a smooth, consistent flow. When handling viscous liquids, the bulb’s elasticity accommodates the increased resistance, allowing the user to maintain control without excessive force. The bulbs are also suitable for use in temperature‑controlled environments, as the latex material retains its flexibility down to 0 °C, making it appropriate for cold‑chain applications such as enzyme assays performed on ice.

Cleaning and maintenance are straightforward: after each use, rinse the bulb with distilled water and allow it to air‑dry. For applications requiring sterility, the bulbs can be autoclaved at 121 °C for 15 minutes without loss of performance, as detailed in the FAQ section. The 72‑count packaging ensures that laboratories can maintain a stocked inventory, reducing the risk of running out of essential consumables during critical experiments.

FAQ

Can these bulbs be used with all pipettor brands?

Yes, the Heathrow HS20622B bulbs are compatible with most standard laboratory pipettors that accept 2 mL dropper bulbs, making them a versatile choice across different equipment brands.

What chemicals are the latex bulbs resistant to?

The natural rubber latex material offers resistance to a wide range of aqueous solutions, mild acids, and bases. For highly corrosive solvents, we recommend verifying compatibility with the specific chemical before use.

How should the bulbs be stored to maintain their elasticity?

Store the bulbs in a cool, dry place away from direct sunlight. Keeping them in their original packaging until needed helps preserve the latex’s flexibility and prevents premature drying.

Is there a warranty or guarantee for defective bulbs?

Heathrow provides a one‑year limited warranty covering manufacturing defects. If a bulb fails under normal use, contact our support team for a replacement or refund.

Can the bulbs be sterilized for cell culture applications?

Yes, the bulbs can be autoclaved at standard laboratory settings (121 °C for 15 minutes) without loss of performance, making them suitable for sterile environments.

What is the recommended disposal method for used latex bulbs?

Used latex bulbs should be disposed of according to your institution’s hazardous waste guidelines. Because they are made from natural rubber, they can be placed in regular waste streams if no hazardous residues are present, but always follow local regulations.

Do the bulbs affect the accuracy of pipetted volumes?

When properly attached and used within the specified 2 mL range, the bulbs maintain volume accuracy comparable to the pipettor’s specifications. Regular calibration of the pipettor ensures optimal performance.
