Test Tube with Stopper

Quick answer: This Test Tube with Stopper provides a sealed, airtight container for holding chemical reactions or samples, preventing evaporation and contamination between uses. Test Tube with Stopper is priced at approximately ₹155 (indicative market benchmark, incl. GST, August 2026).

A test tube with a stopper is a standard test tube fitted with a stopper that seals the open end, creating an airtight environment for a sample or reaction. This is useful for preventing evaporation of volatile liquids, protecting a sample from atmospheric contamination, or safely storing or transporting a small quantity of material between uses. Made from clear glass for visibility of the contents, it’s a basic, versatile piece of equipment used throughout college and school chemistry laboratories.
