Borosilicate 3.3 Glass Test Tubes with Plastic Caps are durable laboratory vessels designed for high-temperature applications, sample storage, and chemical mixing. The use of Boro 3.3 glass ensures superior thermal shock resistance, allowing the tubes to withstand heating and rapid cooling without cracking.

 
Key Features
  • Material: High-quality Borosilicate 3.3 glass, known for its chemical stability and low expansion coefficient.
  • Cap Type: Typically features a Polypropylene (PP) screw cap or push-on cap.
    • Screw Caps: Provide a leak-proof seal for long-term storage or transport.
    • Push-on/Snap Caps: Ideal for quick temporary covering.
  • Capacity & Sizes: Available in a wide range of standard dimensions:
    • Small: 10x75mm (3mL), 12x100mm (7mL).
    • Medium: 16x125mm (14mL), 16x150mm (15mL).
    • Large: 18x180mm (30mL), 25x150mm (50mL).
  • Wall Thickness: Standard thickness is approximately 1.0mm to 1.2mm, providing durability for heavy-duty lab use. 
Usage & Maintenance
  • Autoclavable: Both the Boro 3.3 glass and the PP plastic caps are generally steam-autoclavable at 121°C.
    • Note: Caps should be placed loosely during the autoclave cycle to prevent pressure build-up.
  • Chemical Resistance: Highly resistant to acids, alkalis, and solvents, reducing the risk of leaching contaminants into your samples.
  • Graduations: Some models include white or blue printed graduations for easy volume estimation.
