Why choose this product

High-Quality Borosilicate Glass for Reliable Results

Karter Scientific test tubes are crafted from premium borosilicate glass, offering excellent thermal shock resistance and chemical inertness. This ensures consistent, contamination-free experiments, especially in Indian labs exposed to humidity and variable temperatures. The tubes are factory-sealed and imported directly from the USA, guaranteeing authenticity and durability over soda-lime alternatives, which may leach contaminants or crack under thermal stress.

Ideal for Lab Professionals and Educators in India

Designed for scientific research, educational demonstrations, and chemical storage, these test tubes support precise measurements and safe handling. They are suitable for use in Indian laboratories, research centers, and universities, providing a cost-effective, durable alternative to local glassware. Skip if you require larger volumes or specialized micro-test tubes; these are optimized for small-scale experiments and sample handling.

How to use

  • Prepare the Test Tube — Clean the tube thoroughly, then dry before use. Ensure cork stopper is intact and fits snugly.
  • Conduct Experiments — Fill with sample or reagent, seal with cork, and heat or store as required. Avoid rapid temperature changes with volatile chemicals.
  • Cleaning & Storage — After use, wash with appropriate cleaning agents, dry completely, and store in a rack or sealed container for next use.
