Rimless Test Tubes
Manufacturer: United Scientific
The United Scientific Rimless Test Tubes are crafted from high-quality, pre-cleaned borosilicate glass, making them a staple for everyday clinical, educational, and industrial laboratory environments. Designed without rims, these tubes allow for smooth pairing with standard rubber stoppers and seamless storage in high-density test tube racks. Thanks to the exceptional properties of borosilicate glass, these test tubes offer outstanding resistance to chemical attack and thermal shock. They are engineered to transition effortlessly between hot and cold applications, are fully reusable, and can withstand repeated autoclave sterilization cycles without losing structural integrity.

Key Functional Benefits:
- Strict Outer Diameter Tolerances: The rimless design ensures an unvarying diameter from the top of the tube to the start of the round bottom. This maximizes compatibility with automated liquid handlers and racking systems
- Pre-Cleaned Convenience: Tubes arrive pre-cleaned and packed carefully to reduce ambient dust contamination, saving your team valuable preparation time before initial use
- Superior Chemical Resistance: Minimizes the risk of glass leaching or ion exchange altering the $\text{pH}$ or composition of sensitive chemical reagents and biological buffers
Laboratory Handling Best Practices:
- Autoclaving Configuration: When autoclaving rimless tubes containing media or samples, use loose-fitting plastic caps, foam plugs, or an aluminum foil wrap. Never seal a glass tube with a tight rubber stopper before autoclaving; the expanding air inside will cause structural failure or violent popping.
- Direct Flame Heating: Always utilize a designated test tube clamp. Position the tube at a 45° angle and move it continuously through the flame to distribute thermal energy evenly and avoid hazardous fluid "bumping."
- Centrifugation Note: Ensure that the outer diameter of the tube matches your centrifuge rotor adapters perfectly. Unsupported glass walls under high relative centrifugal force (RCF) can stress the borosilicate structure and cause fractures.
