Frequently asked questions
Do these tubes provide a secure leakproof seal?
Yes, these Simport Micrewtube Tubes are engineered to provide a positive, leakproof seal, ensuring maximum sample integrity even under demanding laboratory conditions.
This robust sealing capability is achieved through two key design features:
- A flexible sealing lip integrated inside the screw cap, which creates a secure, tight seal against the tube wall.
- A deep internal lip that prevents the sample contents from contacting the cap threads, thereby minimizing the risk of contamination.
These tubes maintain their seal integrity while withstanding centrifugation forces up to 17,000g.
How does the tube design minimize contamination?
The Simport Micrewtube is engineered with specific features to maintain high sample integrity and minimize contamination:
- Deep Internal Lip: The tube features a deep internal lip designed to prevent the contents from contacting the cap threads, which significantly reduces the potential for contamination.
- Positive Leakproof Seal: A flexible sealing lip located inside the screw cap ensures a positive, leakproof seal, even when subjected to adverse laboratory conditions.
- Attachment Loops: Each cap is supplied with an attachment loop to prevent cap loss or mix-up, further aiding in contamination control and sample traceability during handling.
Can the tubes withstand high centrifugation forces?
Yes, these Micrewtube tubes are robustly designed for high-speed laboratory applications. They are rated to withstand centrifugation forces up to 17,000g. This capability, combined with the positive leakproof seal, ensures sample integrity during rigorous processing.
What sizes and formats are available?
The Simport Micrewtube Tubes offer versatile configurations, featuring three volume capacities and distinct tube bottom styles designed for various applications.
Available Volumes (Sizes):
- 0.5 mL
- 1.5 mL
- 2.0 mL
Tube Formats (Bottom Styles):
- Self-Standing: Features a stable, flat base for convenient benchtop use without a rack.
- Conical Bottom: This tapered design is optimized for high-speed processing, aiding in maximum pellet recovery. These tubes are rated for centrifugation up to 17,000g.
- No Skirt: A fully conical configuration often used when compatibility with specialized equipment or precise small volume retrieval is required.
What bottom styles are offered?
The Simport Micrewtube Tubes are available in three distinct bottom configurations to accommodate various sample preparation and storage needs:
- Self-Standing: These tubes feature a stable, skirted base, allowing them to stand upright securely on a flat surface without the need for a separate rack.
- Conical Bottom: This tapered design is optimal for micro-sample applications, facilitating maximum sample concentration and recovery after high-speed centrifugation (up to 17,000g).
- No Skirt: These are conical bottom tubes without the stabilizing skirt, designed for use in specific centrifuge rotors or racks that require minimal tube diameter clearance.
Is sterility an option for these tubes?
Yes, the Simport Micrewtube Tubes are available in both Sterile and Non-Sterile configurations to meet your specific laboratory needs. This versatility allows you to choose the appropriate level of cleanliness required for your sample storage and processing applications.
Can these tubes be autoclaved?
No, these tubes cannot be autoclaved. The closure is made of high-density polyethylene, which is not suitable for autoclaving.
Do the caps include attachment loops?
Yes, these Simport Micrewtube Tubes are supplied with screw caps featuring integral attachment loops.
This design is a key safety feature that aids in contamination control and sample integrity by helping to:
- Prevent the loss or accidental mix-up of the cap and sample.
- Ensure procedural safety and traceability during handling.
- Minimize the risk of cross-contamination by keeping the cap secured near its corresponding tube.
