Borosilicate Glass Flat Bottom Test Tube Heat Resistant Smooth Rim

Description

Overview

Engineered for stability and thermal resistance, these Flat Bottom Borosilicate Glass Test Tubes offer a versatile solution for laboratory testing, chemical mixing, sample storage, and display applications. Crafted from premium 3.3 borosilicate glass, they feature a self-standing flat base and a smooth, fire-polished rim for easy pouring and secure sealing.

Key Features

• 3.3 Borosilicate Glass: Highly resistant to thermal shock, sudden temperature shifts, and aggressive chemical reagents.

• Self-Standing Flat Base: Stands upright independently on flat surfaces, reducing the risk of spills without strictly requiring a tube rack.

• Fire-Polished Smooth Rim: Features a smooth, reinforced bead for safe handling, drip-free pouring, and easy insertion of stoppers or rubber bungs.

• Uniform Wall Thickness: Provides balanced thermal expansion to withstand direct heating via hot plates or low-flame burners.

• Autoclavable: Fully reusable and suitable for repeated steam sterilization and oven drying.

Specifications

Note: While flat-bottom tubes are self-standing on level surfaces, using a standard test tube rack is still recommended during high-temperature heating or vigorous mixing for optimal laboratory safety.
