PYREX® test tubes are made from special borosilicate tubing to give them an optimum wall thickness. They are highly resistant to thermal shock, chemical corrosion, and physical impact.
This fire-polished beaded rimmed test tub features a permanent white marking spot, ensuring that important information about the contents is not lost or erased during the course of an experiment.

- Heating: This test tube is designed for heating by hot plate, flame, oven, microwave or heating mantles. In normal service it can be heated many times to 230°C. It can be heated one time to 490°C in extreme service.
- Cooling: This test tube can be cooled to -230°C. DO NOT plunge it directly into a liquid coolant. Place it in the vapor phase of the liquified gasses for slow cooling prior to immersion in the coolant.
Safety Tips:
- Always replace glass laboratory containers that have become scratched or abraded. These defects will make the glass prone to breakage while in use.
- The maximum working temperature for PYREX glassware is 490°C. However, once the temperature exceeds 150°C, ensure that heating and cooling is achieved in a slow and uniform manner.
- Do not use hydrofluoric or hot phosphoric acid in glass.
- Hot alkalis will etch glass.
