PYREX 9mL Rimless Reusable Culture Tubes Glass Pack of 50

Description

Product Overview

The PYREX 9mL Rimless Reusable Culture Tubes are engineered from premium borosilicate glass, a material renowned for its superior thermal stability, chemical inertness, and resistance to scratching. Each tube measures 13x100mm, providing a generous 9mL volume that accommodates a broad spectrum of biological, chemical, and industrial assays. The rimless design eliminates the traditional glass lip, reducing the risk of pH alteration and contamination that can occur with soda‑lime glass alternatives. With a round bottom, the tubes promote uniform mixing and facilitate easy centrifugation, making them versatile for cell culture, microbiology, and analytical chemistry procedures. The pack contains 50 tubes, each weighing approximately 1.29 pounds for the entire set, and is packaged in dimensions of 7.2 x 5.39 x 5.35 inches for convenient storage. Manufactured by Corning Incorporated, Life Sciences, a trusted name with over a century of experience in scientific glassware, these tubes meet rigorous industry standards and are backed by a strong track record of reliability in research laboratories worldwide.

Usage

These culture tubes are perfectly suited for a variety of environments, ranging from high‑throughput research laboratories to educational settings such as high school and university biology classrooms. Their chemical resistance allows for the handling of aggressive reagents, acids, bases, and organic solvents without compromising tube integrity. In microbiology labs, the rimless architecture minimizes aerosol formation during inoculation, enhancing safety for technicians. For home science enthusiasts, the clear glass provides visual insight into reaction progress, encouraging hands‑on learning and experimentation. The tubes are also compatible with standard laboratory accessories, including tube racks, incubators, and autoclaves, ensuring seamless integration into existing workflows. Whether you are cultivating bacterial colonies, performing enzyme assays, or conducting small‑scale synthesis, the PYREX 9mL tubes deliver consistent performance and reproducible results.

FAQ

Can these tubes be autoclaved?

Yes, the PYREX 9mL culture tubes are made from borosilicate glass that tolerates standard autoclave cycles (121°C, 15 psi) without deformation or loss of clarity.

Do the tubes come with caps?

No, the product is supplied without caps to give users flexibility in choosing compatible sealing options such as silicone plugs, cotton, or specialized screw caps based on their specific experimental needs.

What is the advantage of the rimless design?

The rimless design reduces the surface area where liquid can cling, minimizing pH changes and contamination that are common with traditional glass rims, thereby improving the accuracy of sensitive assays.

Are these tubes compatible with standard tube racks?

Absolutely. The 13x100mm dimensions conform to common laboratory tube rack specifications, allowing seamless integration into existing storage and incubation setups.

How does the round bottom benefit my experiments?

The round bottom promotes even distribution of cells and reagents, facilitating better mixing and more consistent growth conditions, especially during shaking or centrifugation steps.
