Latex Dropper Bulbs for Labs Pipet 2ml Pack of 100 by Scienfocus

Description

Product Overview

Scienfocus presents a premium set of latex dropper bulbs specifically engineered for laboratory pipetting applications. Each bulb delivers a precise 2 ml volume, ensuring consistent fluid transfer across a wide range of experimental protocols. Constructed from high‑temperature resistant latex rubber, the bulbs maintain structural integrity when exposed to hot solutions, strong acids, and alkaline environments, making them suitable for demanding chemical handling tasks. The material’s inherent elasticity provides a strong suction force, allowing users to draw liquids quickly and release them smoothly without splashing. With a pack of 100 units, laboratories can stock sufficient supplies for routine assays, high‑throughput screening, and educational demonstrations.

Key specifications include a compact size that fits standard pipette stems, a weight of approximately 5.61 ounces per pack, and compliance with industry standards for laboratory accessories. The product dimensions of 7.05 x 5.39 x 2.36 inches facilitate easy storage in drawer compartments or on bench tops. The bulbs are designed for repeated use; after thorough washing, they can be sterilized and redeployed, reducing waste and operational costs. Their soft texture enhances user comfort during prolonged pipetting sessions, minimizing hand fatigue and improving overall workflow efficiency.

Usage

These latex dropper bulbs excel in a variety of laboratory settings, from analytical chemistry labs to biology research facilities. They are ideal for transferring reagents, titrating solutions, and performing precise dilutions in protocols such as spectrophotometric assays, enzyme kinetics, and cell culture media preparation. The bulbs’ heat resistance allows them to be used with pre‑heated solutions up to 80 °C, while their chemical resistance ensures compatibility with solvents like ethanol, methanol, and dilute acids without degradation.

In educational environments, the bulbs provide a safe and reliable tool for students learning proper pipetting techniques. Their reusable nature aligns with sustainability initiatives on campus, encouraging responsible resource management. For quality control laboratories, the consistent 2 ml delivery reduces variability, supporting compliance with stringent analytical standards. The easy‑connect design enables quick attachment to both standard transfer pipettes and burettes, streamlining setup time and minimizing downtime during critical experiments.

FAQ

Can the dropper bulbs be sterilized for microbiology work?

Yes, the latex material tolerates standard autoclave cycles at 121 °C for up to 15 minutes. After autoclaving, allow the bulbs to cool before reuse to maintain elasticity.

What pipette sizes are compatible with these bulbs?

The bulbs are designed for standard 2 ml transfer pipettes and fit most common burette stems. They can also be used with larger pipette models, provided the stem diameter matches the bulb’s opening.

How many times can a bulb be reused before performance degrades?

When properly cleaned and stored, each bulb can be reused dozens of times. Performance may decline if the bulb shows visible cracks, permanent deformation, or loss of elasticity, at which point replacement is recommended.

Are the bulbs safe for use with organic solvents?

The latex formulation is compatible with many organic solvents such as ethanol and methanol. However, prolonged exposure to strong solvents like acetone may affect durability, so it is advisable to limit contact time.

What is the return policy if the product arrives damaged?

Scienfocus offers a 30‑day return window for damaged or defective items. Contact customer support with the order details and photos of the issue; a replacement or refund will be arranged promptly.
