Corning Pyrex 9820-25 Round Bottom Culture Tube 55mL Reusable 72pcs

Description

Product Overview

The Corning Pyrex 9820-25 culture tube is engineered from high‑quality borosilicate glass, delivering exceptional chemical resistance and thermal stability for demanding laboratory environments. With a 55 mL capacity and a precisely machined round bottom, the tube promotes uniform mixing and optimal growth conditions for a wide range of cell cultures, microbial assays, and biochemical reactions. The rimless construction eliminates the need for caps, simplifying the workflow when transferring samples or integrating the tube into automated rack systems.

Each tube measures 25 mm outer diameter and 150 mm length, providing a compact footprint that fits standard laboratory racks and incubators. The clear glass offers excellent optical clarity, enabling researchers to monitor turbidity, color change, and precipitation without disturbing the sample. The product is supplied in a convenient pack of 72, ensuring a consistent inventory for high‑throughput laboratories.

Designed for repeated use, the tube can be autoclaved and chemically cleaned, extending its service life while reducing consumable costs. The robust glass construction resists breakage under normal handling, and the smooth interior surface minimizes sample adhesion, supporting accurate quantitative measurements.

Usage

These culture tubes are ideal for routine cell culture, microbial growth, and enzyme assays performed in academic, industrial, and clinical laboratories. Their rimless design allows seamless insertion into rack holders, facilitating high‑density plate arrangements and automated liquid handling systems. Researchers can easily add media, inoculate samples, and retrieve cultures without the obstruction of a cap, improving workflow efficiency.

In addition to standard incubator use, the tubes withstand a wide temperature range, making them suitable for heat‑shock experiments, cryopreservation, and rapid cooling procedures. The borosilicate glass tolerates exposure to strong acids, bases, and organic solvents, enabling diverse chemical testing without compromising tube integrity.</n

Because the tubes are reusable, they are well‑suited for laboratories seeking to minimize plastic waste and lower operating expenses. Proper cleaning protocols—such as autoclaving at 121 °C for 15 minutes or using laboratory‑grade detergents—restore the tubes to a pristine condition for subsequent experiments.

FAQ

Can the tube be autoclaved without damage?

Yes, the Pyrex 9820-25 tube is designed to withstand standard autoclave cycles (121 °C for 15 minutes). The borosilicate glass maintains its structural integrity, allowing repeated sterilization without cracking or deformation.

Is the rimless design compatible with standard rack systems?

The rimless profile is engineered to fit common laboratory rack dimensions. It slides securely into rack slots, and the absence of a cap reduces the overall height, enabling higher density storage in incubators and workstations.

What cleaning procedures are recommended for reuse?

After use, rinse the tube with distilled water, then soak in a laboratory‑grade detergent solution. Follow with a thorough rinse and autoclave. For stubborn residues, a brief soak in dilute acid or base can be employed, followed by additional rinsing before sterilization.

How does the glass clarity benefit experimental observation?

The clear borosilicate glass allows researchers to monitor turbidity, color change, and precipitate formation directly through the tube wall. This visual access eliminates the need to remove samples for inspection, preserving sterility and reducing handling time.

Are these tubes suitable for high‑throughput screening?

Yes, the 25 mm outer diameter and 150 mm length fit standard high‑density rack formats, making them compatible with automated liquid handling platforms and plate readers used in high‑throughput applications.
