- Volume: 2.0 mL. This capacity is ample for most of my sampling needs, balancing portability with sufficient volume for analysis.
- Style: Freestanding. This allows for easy storage and organization on lab benches or in field kits.
- Sterility: Nonsterile. While sterilization is required for some applications, the nonsterile nature of these tubes makes them versatile for a wide range of uses.
- Maximum RCF: 20,000 g. This high RCF rating ensures the tubes can withstand demanding centrifugation protocols without compromising integrity.
- Material: Borosilicate glass with a gold-plated finish. The borosilicate glass provides excellent chemical resistance and thermal stability, while the gold-plated finish adds a layer of protection and enhances visibility.
These specifications are crucial for ensuring accurate and reliable sample handling. The high RCF rating and durable glass construction provide peace of mind when processing samples in demanding conditions. The freestanding design is valuable for quick and easy access in the field.
Performance & Functionality
The VWR Screw-Cap Microcentrifuge Tubes perform exceptionally well. The conical shape and large center opening streamline pelleting. The screw-cap design ensures a tight seal, preventing leaks and contamination.
The tubes are highly accurate in volume measurement, which is critical for precise dilutions and reactions. However, the borosilicate glass can shatter if dropped on a hard surface.
The tubes meet my expectations for sample containment and durability. They exceed my expectations for ease of use and reliability in a field setting.
Design & Ergonomics
The tubes are well-designed and comfortable to handle. The clear loop caps are easy to grip and manipulate, even with gloves.
The tubes are lightweight and easy to transport. However, the glass construction makes them more fragile than plastic tubes.
Durability & Maintenance
