Test Tube, Re-usable With Rim, I

The Test Tube, Re-usable With Rim, I is a fundamental laboratory glassware item engineered for general chemical testing, sample heating, and liquid mixing. Manufactured from ASTM E-438 Type-1 Class A, Boro 3.3 glass, this reusable test tube features uniform wall thickness for high mechanical strength and thermal shock resistance. Designed with a reinforced rim at the top, it allows effortless pouring, secure gripping with test tube clamps, and easy neck sealing using standard rubber stoppers. This durable, autoclavable test tube is suited for qualitative analysis, heating reactions over open flames or water baths, and sample handling across educational, clinical, and industrial laboratories. Suitable for chemistry instruction, biological research, pharmaceutical QA/QC, clinical pathology, and industrial chemical testing industries. Supplied by Edulabs.

Storage Instructions

  • Store in designated test tube racks, wooden blocks, or cushioned drawer compartments to prevent roll-off and chipping.

  • Keep in a dry, clean location away from airborne contaminants and harsh chemical vapors.

  • Ensure test tubes are stored vertically or in compartmentalized boxes to minimize mechanical contact between tubes.

  • Store clean tubes inverted in drying racks to ensure full internal moisture drainage prior to storage.

  • Avoid stacking unboxed test tubes horizontally without protective division liners.

  • Keep storage areas away from high-vibration machinery to avoid glass fatigue.

Safety Information

  • Visually check test tubes for cracks, chips, or thin spots before heating or mixing reagents.

  • Always wear protective eyewear, lab coats, and appropriate heat-resistant gloves during flame heating.

  • Angle test tube openings away from personnel when heating liquids over a Bunsen burner flame.

  • Use designated test tube holders or tongs when handling hot test tubes to avoid thermal burns.

  • Do not plunge hot test tubes directly into cold water; allow slow air-cooling to avoid thermal fracture.

  • Do not fill test tubes beyond two-thirds capacity when heating solutions to prevent boil-over hazards.

  • Clean thoroughly after use with soft-bristle test tube brushes to prevent inner wall scratches.

The Test Tube, Re-usable With Rim, I supplied by Edulabs is a cornerstone piece of laboratory glassware designed for everyday experimental, analytical, and instructional tasks. Engineered for durability, this reusable test tube serves as a reliable vessel for mixing reagents, conducting micro-scale reactions, heating solutions, and holding temporary samples.

Crafted from premium ASTM E-438 Type-1 Class A, Boro 3.3 borosilicate glass, this test tube exhibits outstanding chemical resistance against acidic, basic, and solvent exposure. Its low expansion coefficient delivers high resistance to sudden temperature variations, enabling safe heating over direct open flames, in heating mantles, or in hot water baths without compromising structural stability.

The tube features a uniform wall thickness across its entire body, providing mechanical strength and heat distribution. The top opening is finished with a smooth, reinforced bead or rim. This rim design enhances mechanical strength around the rim mouth, facilitates smooth liquid pouring without dripping, and provides a secure seat for rubber stoppers, corks, or closure caps.

Available in a wide range of sizes spanning from 3 ml up to 170 ml nominal capacity, these test tubes cater to diverse laboratory requirements from micro-chemistry teaching to large-volume industrial analytical sampling. Their fully autoclavable nature allows easy sterilization for repeated biological and chemical laboratory protocols.

Edulabs manufactures these reusable rimmed test tubes to rigorous technical specifications, providing educational, medical, and industrial laboratories with dependable quality glassware for everyday scientific applications.
