Glass Test Tubes - High-Quality Borosilicate Glass for Reliable Laboratory Use

Precision and Stability with Glass Test Tubes

Our Glass Test Tubes, made from premium borosilicate glass, ensure minimal pH change and prevent contaminants typically leached from soda-lime glass. These test tubes are well annealed, heat resistant, and chemically stable, making them essential for accurate and reliable laboratory work.

Key Features:

• High-Quality Material: Crafted from borosilicate glass for enhanced heat resistance and chemical stability.
• Fire-Polished Beaded Rims: Ensures smooth, safe edges for handling.
• Versatile Designs: Available in flat, round, or conical bottoms; options to accept ground glass stoppers or screw caps.
• Labelling Area: Includes a small ground glass or white glaze area for easy labelling with a pencil.

Uses and Benefits:

• Chemical Handling: Ideal for qualitative experiments and assays, reducing mass loss and easing cleaning.
• Monitoring Contents: The spherical bottom and vertical sides facilitate easy monitoring of reactions.
• Gas Containment: The long, narrow neck slows the spreading of gases, maintaining a controlled environment.

Specifications:

• Material: Borosilicate glass.
• Dimensions: Ranges from 50 mm to 250 mm in length and 13 to 20 mm in width.
• Applications: Suitable for chemical reactions, heating solutions, and culturing microorganisms.

Boiling Tubes:

• Purpose: Designed for strong heating in a Bunsen burner flame, with a wide diameter to prevent bumping.
• Durability: Thick-walled to withstand direct heating, used in tests such as the sodium fusion test.
