Ensuring sample viability during ultra-low temperature storage requires specialized vessels designed for thermal stability and secure sealing. Professional cryogenic tubes are precision-molded from high-purity polypropylene (PP) to withstand the extreme stresses of liquid nitrogen vapor phase storage and repeated freeze-thaw cycles. As a specialized category within our cooling range under heating and cooling technology, these tubes are vital for clinical research and long-term biobanking.
Why Choose Professional Cryogenic Tubes?
Our curated collection of cryo-vessels is designed for technical reliability and ease of identification:
- High-Performance Sealing: We stock Thermo Nunc CryoTubes in various volumes, including 1.8 mL, 3.6 mL, and 4.5 mL, featuring internal threads to ensure a leak-proof seal during storage.
- Stable Self-Standing Designs: Utilize LLG Cryotubes (available in 2.0 mL and 5.0 mL) featuring a stand foot and external or internal threads, allowing for easy one-handed operation on the laboratory bench.
- Visual Identification Systems: Enhance your organization with LLG Insert Cap Disks, available in blue and other colors with a star-shaped design for quick visual categorization of samples.
- Advanced Sample Containment: Explore specialized Thermo Scientific Sample Bags (LDPE, 10.2x15.2 cm) designed for secondary containment and protection of high-value biological materials.
LabFriend supplies cryogenic tubes from all industry-leading manufacturers specialized in high-performance sample preservation and identification:
- Thermo Scientific: The premier provider of Nunc-branded cryotubes and specialized LDPE sample bags for clinical and research applications.
- LLG Labware: Specialist in functional and cost-effective polypropylene cryotubes and color-coded insert cap disks.
- Eppendorf: Renowned for high-precision laboratory vessels and specialized liquid handling systems.

Frequently Asked Questions
1. What is the advantage of internal thread cryotubes like the Thermo Nunc range?
Internal threads typically offer a more consistent seal and a lower profile, which helps maximize storage density within cryogenic boxes and racks while reducing the risk of contamination.
2. Can LLG Cryotubes with a stand foot be used in standard racks?
Yes, the stand foot design allows the tube to stand independently on a benchtop but is still compatible with most standard cryogenic racks and boxes that accommodate 12-13mm diameter tubes.
3. What are the LLG Insert Cap Disks used for?
These star-shaped disks snap into the top of cryotube caps, allowing researchers to color-code different sample types or experiments without needing to label every individual cap surface.
4. Are these polypropylene tubes safe for liquid nitrogen?
Yes, professional cryotubes from Thermo Scientific and LLG are specifically manufactured from medical-grade polypropylene designed to remain stable and leak-proof at temperatures as low as -196°C in the vapor phase.
