McKesson Glass Culture Tubes Borosilicate Polished Rims 250 Count

Description

Product Overview

McKesson’s glass culture tubes are engineered from high‑grade borosilicate glass, a material renowned for its exceptional chemical resistance and thermal stability. The fire‑polished rims eliminate sharp edges, reducing the risk of breakage and providing a smooth surface that resists chipping during routine handling. Each tube holds a precise 10 mL volume, calibrated to deliver consistent measurements across a wide range of experimental protocols, from microbiological cultures to chemical titrations.

Dimensions of the tubes are optimized for standard laboratory equipment, fitting comfortably into incubators, centrifuges, and rack systems. The transparent walls allow clear visual monitoring of sample growth, color changes, or precipitate formation without the need to open the tube, preserving sterility and safety. The packaging includes 250 individually sealed tubes, ensuring that each unit remains contaminant‑free until the moment of use.

Manufactured under strict quality‑control standards, these tubes meet the rigorous demands of research institutions, teaching laboratories, and industrial settings. The combination of borosilicate durability, fire‑polished rims, and precise volume capacity makes them a reliable choice for any application that requires consistent, repeatable results.

Usage

These culture tubes excel in a variety of laboratory environments. In microbiology, they provide an ideal vessel for growing bacterial, fungal, or yeast cultures, allowing researchers to observe colony morphology and perform downstream analyses such as Gram staining or DNA extraction. The chemical‑resistant glass ensures that aggressive media, solvents, or reagents do not degrade the tube walls, preserving sample integrity throughout the experiment.

In chemistry classrooms, the 10 mL capacity is perfect for small‑scale reactions, titrations, and qualitative tests. Students benefit from the clear visual cues the tubes provide, while instructors appreciate the safety afforded by the fire‑polished rims, which reduce the chance of accidental cuts during handling. The tubes also perform well in industrial quality‑control labs, where they are used for stability testing, sample storage, and routine analytical procedures.

FAQ

What makes borosilicate glass suitable for culture tubes?

Borosilicate glass has a low coefficient of thermal expansion, which means it can withstand rapid temperature changes without cracking. It also offers excellent resistance to a wide range of chemicals, making it ideal for both biological and chemical applications where durability and purity are essential.

Can these tubes be autoclaved?

Yes, the tubes are designed to tolerate standard autoclave cycles (121 °C for 15‑30 minutes). The fire‑polished rims maintain their smoothness after repeated sterilization, ensuring that the tubes remain safe and functional for multiple uses.

Are the tubes compatible with standard rack systems?

Absolutely. The dimensions of the tubes conform to industry‑standard sizes, allowing them to fit seamlessly into most laboratory racks, incubators, and centrifuge adapters. This compatibility simplifies workflow and reduces the need for additional accessories.

What is the recommended storage condition for unused tubes?

Store the unopened tubes in a cool, dry place away from direct sunlight. The sealed packaging protects the tubes from dust and contaminants, preserving their sterility until you are ready to use them.

How does McKesson handle defective or damaged tubes?

If you receive a tube that is cracked, chipped, or otherwise compromised, contact our support team within 30 days of purchase. We will arrange a replacement or refund according to our warranty policy, ensuring that your laboratory operations are not disrupted.
