These borosilicate 3.3 glass test tubes with plastic caps are durable lab tubes for high-temperature work, sample storage and chemical mixing. Boro 3.3 glass resists thermal shock, so the tubes can be heated and cooled quickly without cracking.

Key Features

  • Material: Quality borosilicate 3.3 glass, known for its chemical stability and low expansion.
  • Caps: Polypropylene (PP) screw caps that give a leak-proof seal for storage or transport.
  • Sizes: 16 x 125mm, 16 x 150mm, 18 x 180mm and 25 x 150mm (select from the drop-down).
  • Wall thickness: About 1.0 to 1.2mm, durable enough for heavy lab use.

Use and Care

  • Autoclavable: Both the glass and the PP caps are generally steam-autoclavable at 121°C. Loosen the caps during the autoclave cycle to prevent pressure build-up.
  • Chemical resistance: Highly resistant to acids, alkalis and solvents, so contaminants won't leach into your samples.

Specifications

  • Material: 3.3 borosilicate glass
  • Design: Round bottom with screw cap
  • Brand: None
  • Product of China
