Frequently asked questions
Are the tubes made from high-quality polypropylene?
Yes, these Simport Micrewtube Tubes are manufactured from high-quality polypropylene, specifically chosen for demanding laboratory use. This durable material provides two primary benefits:
- Extreme Temperature Tolerance: The tubes maintain their integrity across an extensive range, suitable for both cryogenic storage (down to -196°C) and thermal processing like autoclaving (up to +121°C).
- High Mechanical Strength: They are built to withstand high g-forces. Standard tubes are rated for up to 17,000g RCF, while the conical bottom variants offer even greater resistance, rated up to 20,000g RCF.
Do these tubes withstand extreme temperatures?
Yes, the Simport Micrewtube Tubes are manufactured from durable polypropylene specifically for use across a wide range of extreme laboratory temperatures. They maintain integrity for both ultra-low storage and sterilization protocols, offering a thermal stability range from -196°C to +121°C.
Key applications for this temperature range include:
- Cryogenic Storage: Suitable for temperatures as low as -196°C for long-term sample preservation.
- Sterilization: Capable of withstanding high temperatures up to +121°C for autoclaving procedures.
What is the maximum centrifugation RCF?
The Simport Micrewtube Tubes are made from resilient polypropylene and are engineered for high-speed centrifugation, offering excellent mechanical strength. The maximum Relative Centrifugal Force (RCF) rating depends on the base configuration you choose:
- Standard Tubes: Capable of withstanding RCFs up to 17,000g.
- Conical Bottom Tubes: Designed for even higher speeds, these variants are rated for RCFs up to 20,000g, making them perfect for efficient pelleting and demanding separation procedures.
What are the available volume capacities?
The Simport Micrewtube Tubes are available in three standard working volumes suitable for various laboratory needs: * 0.5mL * 1.5mL * 2.0mL These tubes are constructed from durable polypropylene and designed to maintain integrity across a wide thermal spectrum, from -196°C (ideal for cryopreservation) up to +121°C (suitable for sterilization). They also offer high mechanical strength, resisting up to 20,000g RCF in conical bottom configurations.
Do these tubes include a white marking area for easy labeling?
Yes, Simport Micrewtube Tubes offer specific variants designed for reliable sample identification and tracking.
Key identification features available include:
- White Marking Area: Select configurations are equipped with a dedicated white rectangular area printed on the tube body, facilitating easy handwritten labeling and clear identification.
- Graduated Markings: Many options are also graduated, enabling quick and accurate estimation of sample volume across the available sizes (0.5mL, 1.5mL, and 2.0mL).
Are conical and self-standing tube bases available?
Yes, the Simport Micrewtube Tubes are manufactured in two highly functional base configurations to suit various laboratory needs:
- Self-Standing: These models have a flat base for convenient bench-top stability, allowing the tube to stand securely without a rack.
- Conical Bottom: This tapered design is optimized for centrifugation, ensuring efficient sample pelleting. The conical variants also offer superior mechanical strength, capable of withstanding up to 20,000g Relative Centrifugal Force (RCF), compared to 17,000g for standard configurations.
How many tubes come per case?
The Simport Micrewtube Tubes are supplied in high volume packaging to support demanding lab workflows. Each case contains 1,000 tubes.
Are these tubes suitable for molecular biology applications?
Yes, Simport Micrewtube® Tubes are suitable for use in molecular biology, biochemistry, and other research applications requiring sample storage and processing.
What are the temperature and centrifugation limits?
Yes, these Simport Micrewtube tubes are engineered from high-quality polypropylene to provide exceptional durability, ensuring sample integrity across extreme laboratory conditions.They can withstand both extreme thermal and mechanical stresses:
- Temperature Tolerance: Usable across an extensive temperature spectrum, ranging from ultra-low cryogenic storage at -196°C up to thermal processing temperatures of +121°C (suitable for autoclaving).
- High Centrifugation Rating (RCF): The robust construction is ideal for high-speed protocols:
- Standard configurations are rated for up to 17,000g.
- Conical bottom variants offer superior strength, rated for up to 20,000g.
Are there options with a white sample ID area?
Yes, Simport Micrewtube Tubes are available in specific configurations that include features essential for efficient sample tracking and identification.
Look for the variants designated as Graduated with White Marking Area. These options provide two key features:
- A white sample ID area for easy, quick written labeling of the contents.
- Graduation marks to help ensure precise volume referencing and accuracy.
