Corning Pyrex 9820-13 9mL Rimless Borosilicate Culture Tube 72 Count

Description

Product Overview

The Corning Pyrex 9820-13 culture tube is engineered from premium borosilicate glass, a material renowned for its chemical resistance, thermal stability, and low leaching characteristics. Each tube holds 9 mL of liquid, providing ample volume for a wide range of microbiological and cell culture protocols. The round bottom design promotes uniform mixing and efficient sedimentation of cells, while the rimless opening eliminates the need for caps, allowing rapid access and easy transfer of samples. The tube dimensions—13 mm outer diameter and 100 mm length—fit standard laboratory racks and incubators, ensuring seamless integration into existing workflows. Packaged in a convenient set of 72 tubes, the product delivers consistent quality and performance for high‑throughput environments.

Usage

These culture tubes are ideal for a variety of laboratory settings, including academic research labs, biotech facilities, and quality‑control laboratories. They excel in applications such as bacterial and fungal culture, yeast propagation, and small‑scale fermentation. The rimless design simplifies inoculation, sampling, and downstream processing, making them especially useful for protocols that require frequent opening and closing of the vessel. Because the glass is non‑reactive, it maintains the integrity of sensitive media and reduces the risk of contaminant leaching, which is critical for experiments that demand precise pH control. The tubes are non‑sterile and intended for single‑use, providing a cost‑effective solution for routine assays where sterilization can be performed in‑house if required.

Why Choose Us

Choosing Corning Pyrex means selecting a brand with over a century of glass‑making expertise and a reputation for reliability in scientific research. The borosilicate composition is specifically formulated to resist thermal shock, allowing the tubes to be safely autoclaved or heated without cracking. Each tube undergoes rigorous quality control to ensure uniform wall thickness, clear visibility, and flawless surface finish, which together enhance observation of culture growth and facilitate accurate measurements. The rimless feature reduces the risk of cap‑related contamination and streamlines workflow, while the round bottom promotes even distribution of cells and nutrients. Additionally, Corning provides responsive technical support and a clear return policy, ensuring that any issues are addressed promptly and that customers receive the best possible value from their purchase.

FAQ

Can these tubes be autoclaved?

Yes, the borosilicate glass construction tolerates standard autoclave cycles (121 °C for 15‑20 minutes) without cracking or deformation.

Are the tubes sterile out of the package?

These tubes are supplied non‑sterile. If sterility is required, they can be sterilized in‑house using autoclaving or gamma irradiation before use.

What is the advantage of a rimless design?

The rimless opening eliminates the need for caps, reducing the risk of contamination from cap residues and allowing faster sample handling during inoculation and sampling.

Do the tubes fit standard incubator shelves?

Yes, the 13 mm outer diameter and 100 mm length are compatible with most laboratory incubator racks and shaking platforms, ensuring stable placement during incubation.

Is there a warranty or guarantee?

Corning offers a limited warranty against manufacturing defects and provides responsive technical assistance to address any product‑related concerns.
