Pyrex 500mL Round Media Storage Bottle with GL45 Orange Screw Cap

Description

Product Overview

The Pyrex 500mL round media bottle is engineered to meet the rigorous demands of modern laboratory environments. Constructed from high‑grade borosilicate glass, the vessel offers exceptional chemical resistance, thermal stability, and clarity, allowing users to visually inspect contents without compromising safety. The bottle features a smooth, uniform wall thickness that reduces the risk of breakage during routine handling, while the precise glass composition resists etching from acidic or basic solutions, ensuring long‑term durability. An integral design element is the orange GL45 screw cap, which provides a secure, leak‑proof seal that meets ASTM standards for laboratory containers. The cap’s threading is engineered for a tight fit, preventing evaporation and contamination, and its vibrant color offers quick visual identification among other glassware. Graduations are etched at 100 mL intervals up to 400 mL, providing easy reference for volume measurements without the need for additional measuring devices. The bottle’s dimensions—approximately 176 mm in height and 86 mm in outer diameter—fit comfortably within standard incubators, refrigerators, and storage cabinets, making it a versatile choice for a wide range of applications.

Usage

Designed for versatility, the Pyrex media bottle excels in a variety of laboratory settings. In microbiology labs, it serves as an ideal container for preparing and storing culture media, allowing researchers to maintain sterility and monitor growth conditions. The clear glass body enables easy visual assessment of turbidity, precipitation, or color changes, which is essential for troubleshooting experiments. In chemistry departments, the bottle’s chemical‑resistant glass makes it suitable for holding reagents, solvents, and standard solutions, while the secure GL45 cap prevents accidental spills during transport between workstations. The bottle also performs well in quality‑control environments where precise volume tracking is required; the etched graduations facilitate quick verification of fill levels, reducing the need for separate measuring cylinders. Its robust construction allows it to withstand temperature fluctuations, making it compatible with autoclaving, refrigeration, and heating on hot plates. Whether used in academic research, industrial R&D, or clinical diagnostics, the Pyrex 500 mL bottle provides a reliable, reusable solution that supports accurate, reproducible results.

FAQ

Can the bottle be autoclaved?

Yes, the Pyrex 500 mL media bottle is made from borosilicate glass that tolerates typical autoclave cycles (121 °C for 15‑30 minutes) without cracking or losing its clarity. The GL45 cap should be removed before autoclaving to allow pressure equalization and prevent cap deformation.

Is the GL45 cap compatible with other Pyrex containers?

The GL45 screw cap is a standard thread size used across many Pyrex laboratory bottles, making it interchangeable with other Pyrex containers that share the same threading. However, for optimal sealing performance, it is recommended to pair the cap with bottles of the same design and material.

What is the best cleaning method for the bottle?

For routine cleaning, rinse the bottle with distilled water followed by a mild detergent solution. For stubborn residues, soak the bottle in a 10 % nitric acid solution, then rinse thoroughly with deionized water. Avoid abrasive scrubbers that could scratch the glass surface.

How does the bottle handle acidic or basic solutions?

The borosilicate glass composition offers excellent resistance to both acidic and basic solutions, minimizing the risk of leaching or glass etching. This makes the bottle suitable for storing a wide range of reagents, from strong acids to alkaline buffers, without compromising sample integrity.

What warranty or guarantee is provided?

Karter Scientific provides a 30‑day satisfaction guarantee. If the bottle arrives damaged or does not meet performance expectations, customers can contact support for a replacement or refund, subject to verification of the issue.
