McKesson Glass Culture Tubes Borosilicate 3 mL Rims 250 Count

Description

Product Overview

McKesson delivers a premium line of glass culture tubes designed specifically for scientific and educational laboratories. Each tube is crafted from high‑quality borosilicate glass, a material renowned for its exceptional chemical resistance, low thermal expansion, and durability under repeated heating and cooling cycles. The 3 mL capacity provides a versatile volume for a wide range of applications, from small‑scale tissue culture experiments to blood bank sample storage. The tubes feature fire‑polished rims, a finishing process that smooths the glass edge to eliminate sharpness, reducing the risk of sample contamination and making them safe to handle during routine laboratory procedures.

The clear, non‑sterile tubes arrive shrink‑wrapped in a protective plastic film that keeps them particle‑free until the moment of use. This packaging approach balances cost‑effectiveness with the need for a clean environment, ensuring that researchers receive tubes that are ready for immediate deployment in their protocols. With a pack size of 250, laboratories can maintain a steady inventory, reducing the frequency of re‑ordering and minimizing downtime caused by depleted supplies.

Usage

These culture tubes are ideally suited for a broad spectrum of laboratory settings. In academic science classes, they serve as an excellent teaching tool for demonstrating basic principles of cell culture, allowing students to observe growth patterns in a controlled environment. In research laboratories, the tubes are frequently employed for cultivating microorganisms, maintaining cell lines, and storing small volumes of blood or plasma for diagnostic testing. The fire‑polished rim design facilitates easy sealing with standard caps or stoppers, ensuring a secure, leak‑proof closure that preserves sample integrity during incubation or transport.

Because borosilicate glass resists leaching of ions, it minimizes the risk of pH shifts that could affect sensitive biological samples. This property is especially valuable in applications where precise pH control is critical, such as enzyme assays or hormone studies. The round‑bottom shape promotes uniform heat distribution when tubes are placed in water baths or incubators, enhancing the consistency of experimental conditions across multiple samples.

Laboratories that handle blood products benefit from the tubes’ ability to withstand repeated autoclaving without compromising structural integrity, making them a reliable choice for routine sterilization cycles. Additionally, the clear glass allows for straightforward visual inspection of sample clarity, color changes, or microbial growth, eliminating the need for additional instrumentation in many routine checks.

FAQ

Are these tubes sterile?

No, the tubes are supplied non‑sterile but are shrink‑wrapped to keep them free from particles and contaminants until opened. Users can sterilize them in an autoclave or by other standard laboratory sterilization methods before use.

Can the tubes be autoclaved?

Yes, the borosilicate glass construction is designed to withstand repeated autoclave cycles without cracking or deforming, making them suitable for routine sterilization procedures.

What type of caps are compatible with these tubes?

The fire‑polished rim is compatible with standard laboratory caps and stoppers, including screw‑type caps and rubber or silicone plugs, allowing users to choose the sealing method that best fits their protocol.

Is the packaging recyclable?

Both the glass tubes and the protective plastic film are recyclable. McKesson encourages users to follow local recycling guidelines to responsibly dispose of packaging materials.

How does the borosilicate material benefit cell culture?

Borosilicate glass has a low coefficient of thermal expansion and does not leach ions into the culture medium, which helps maintain a stable environment for cells and reduces the risk of unwanted chemical interactions that could affect growth or viability.
