Rimmed Test Tubes
Manufacturer: United Scientific
Description
Choose from a wide range of outer diameters and capacities to fit your specific racks and centrifuge rotors. Available in convenient small packs or bulk value cases.
Features:
- Mechanical Reinforcement: The rimmed top strengthens the most vulnerable part of the tube, minimizing chipping during pouring or cleaning
- Thermal Shock Resistance: Borosilicate glass allows for safe heating of samples and can transition from heated plates to cooling racks without cracking
- Chemical Durability: Highly resistant to most acids, bases, and organic solvents, preventing sample contamination from leached ions
- Stopper Compatibility: Necks are precisely finished to provide a tight seal with standard rubber stoppers (refer to the stopper sizing chart in the product specifications)
Laboratory Management Insights:
- Autoclaving Tip: When sterilizing tubes containing liquids, ensure they are placed in a rack that allows for proper steam circulation. Do not seal with a tight-fitting stopper during the autoclave cycle to avoid pressure-induced failure.
- Heating Safety: Always use a test tube holder when heating over an open flame and point the mouth of the tube away from yourself and others to prevent "bumping" accidents.
- Reuse Protocols: For high-purity research, ensure tubes are cleaned with a non-abrasive brush and rinsed with deionized water to prevent residue buildup that can etch the glass over time.
