Description

Simport Scientific . The washer seal secured in the top of the cap ensures a positive leakproof seal, time after time, keeping the integrity of the small sample under even the most adverse conditions. The flat-top cap provides a writing surface and can be used with automatic capping machines in packaging industries. Tamperproof screw cap with washer seal and flat top is molded with a deep internal lip that fits snugly against the interior wall of the tube. It will prevent the contents from coming in contact with the seal or threads, thereby reducing the chances of sample contamination. The cap's high profile facilitates manipulation, especially in aseptic procedures. All tubes and closures are manufactured in a clean environment. This series of tubes are available either plain or with printed graduations and a white marking area for sample identification. Perfect for cryogenic work. Non skirted tubes can be centrifuged up to 20,000 x g. Skirted tubes can be centrifuged up to 17,000 x g. Will withstand temperatures from -196°C to +121°C.

Frequently asked questions

Does the Micrewtube offer a wide temperature range?

Yes, the Simport Micrewtube is designed to withstand a wide temperature range, from -196°C to +121°C. This makes it ideal for various applications, including cryogenic work and autoclaving, ensuring sample integrity across extreme conditions.

Are these Micrewtubes suitable for high-speed centrifugation?

Yes, the Micrewtubes are designed for high-speed centrifugation. Non-skirted tubes can be centrifuged up to 20,000 x g, while skirted tubes can withstand up to 17,000 x g.

Does the cap design minimize sample contamination?

Yes, the cap is specifically designed to minimize sample contamination, which is a major selling point of the Micrewtube. The flat-top screw cap features a deep internal lip that fits snugly against the tube’s interior wall. This design ensures that the sample contents cannot contact the threads or the integrated washer seal, thereby preserving the integrity and purity of your samples.

Is the flat-top cap suitable for writing?

Yes, absolutely. The Simport Micrewtube features a flat-top screw cap that is specifically designed to function as a convenient writing area for easy and reliable sample identification. These tubes may also be available with printed graduations and a white marking area on the tube body for additional labeling flexibility.

Does the cap feature a high-quality washer seal?

Yes, the Simport Micrewtube features an integrated washer seal secured within the cap to guarantee exceptional sample integrity.

This design ensures a positive, leakproof seal, which is vital for demanding laboratory applications:

  • It maintains containment even under high centrifugation forces (up to 20,000 x g for non-skirted tubes).
  • It provides the necessary security for cryogenic storage, as the tube system can withstand extreme temperatures ranging from -196°C up to +121°C.
Do these tubes support automatic capping?

Yes, these Micrewtubes are fully compatible with automatic capping machines. The flat-top design of the screw cap is specifically engineered to interface smoothly with automated equipment, which helps streamline high-throughput laboratory processes.

What is the capacity of the Micrewtube?

The Simport Micrewtube is currently available in a 1.5 mL capacity. This size is engineered for high-reliability sample storage and handling, particularly suitable for cryogenic preservation.

Does the Micrewtube have a reliable leakproof seal?

Yes, the Simport Micrewtube is specifically designed to provide a positive, time after time, leakproof seal. This is achieved using a robust washer seal secured within the flat-top screw cap.

This design ensures sample integrity is maintained under even the most adverse conditions. The tube can withstand demanding thermal applications, including temperatures ranging from -196
C up to +121
C
, making it ideal for cryogenic work.
