Lab Pyrex Test Tube with Screw Cap

Lab Pyrex Test Tube with Screw Cap

Screw cap glass test tubes are high-quality laboratory vessels made from durable borosilicate glass, featuring precision-threaded necks for secure closure. Designed for applications requiring chemical resistance, thermal stability, and airtight sealing, these tubes are ideal for sample storage, culturing, and heating procedures.

Features:

Made of borosilicate glass:Offers excellent thermal resistance and chemical durability, suitable for heating, boiling, and autoclaving.

Secure screw cap design:Available with polypropylene (PP) or phenolic resin caps, ensuring a leak-proof seal for safe transport and storage.

High thermal tolerance:Withstands high temperatures (up to 500°C for borosilicate glass), compatible with flame sterilization and dry heat sterilization.

Reusable and autoclavable:Both the tube and the cap can be sterilized, reducing long-term laboratory costs and waste.

Advantages:

Excellent seal integrity prevents leaks and contamination

Clear glass body allows for easy visual observation

Reusable and cost-effective for routine lab use

Safe for thermal cycling and high-temperature reactions
