50ml PP Test Tubes 20-Piece Pack

A practical 20-piece pack of cylindrical test tubes, each sized at 11.00 × 3.00 × 3.00 cm (4.32 × 1.18 × 1.18 inches) with a stated capacity of 50 ml. Constructed from homopolymer polypropylene, they offer good thermal stability up to 100°C and mechanical resilience against dropping or stacking pressure. The seamless, one-piece body eliminates weak joints or seams where leaks could occur. Transparent walls enable direct observation; tight-fitting lids prevent dust ingress and slow evaporation. Smooth inner walls facilitate complete liquid recovery during pouring or pipetting. Ideal for science fairs, homeschool curricula, microbiology starter kits, or organising small hardware, seeds, or cosmetics — wherever compact, reusable, and clearly visible containment is needed.
