Pre-filled Cryobox | Cryo Tubes | 10 × 10 Format | PP | 100 Tubes/Box
Description
"Write on a frozen tube with a marker that smears, fades, or disappears after condensation builds up. Then sort dozens more that all look identical. Skip all of that."
Every Biofargo 1.5 mL External Thread Cryotube is designed for reliable cryogenic storage, clear sample identification, and efficient daily laboratory handling: a sterile polypropylene cryogenic vial featuring a red flat external screw cap, self-standing base, and integrated white writing area for direct sample marking. The high-contrast writing panel improves manual labeling visibility while reducing dependence on adhesive labels that may peel or degrade under low-temperature conditions.
The self-standing bottom enhances stability during aliquoting and processing workflows, while the external thread structure minimizes contamination risk within the sealing area and supports dependable leak resistance during storage and transport. Manufactured from durable medical-grade polypropylene (PP), the tubes maintain integrity across repeated freeze–thaw cycles and routine cryogenic laboratory operations.
Compatible with standard cryogenic storage racks, cryoboxes, and laboratory freezer systems for 1.5 mL cryotubes.
Features
- ● Integrated White Writing Area — Screen-printed marking panel supports direct handwriting and improves tube identification during freezer storage workflows.
- ● External Thread, Cleaner Sealing Area — External cap design reduces direct sample contact with the sealing interface and supports contamination control.
- ● Red Flat Cap for Fast Visual Sorting — High-visibility colored cap improves sample grouping and workflow organization in multi-sample environments.
- ● Self-Standing Bottom — Stable freestanding structure minimizes tipping during filling, labeling, and laboratory processing.
- ● Cryogenic Storage Ready — Designed for ultra-low temperature storage and repeated freeze–thaw handling in research and biobanking workflows.
- ● RNase/DNase-Free, Endotoxin ≤ 0.005 EU/mL — Sterile, gamma-irradiated. Suitable for molecular biology and clinical research applications.
- ● Durable Polypropylene Construction — High-strength PP material resists cracking and maintains structural integrity under cryogenic conditions.
- ● Bulk Packaging for Laboratory Throughput — Supplied as 100 tubes/box and 30 boxes/case for efficient sample management and inventory control.
