Description

"Store small-volume samples in tubes that blend together in crowded freezer racks, lose handwritten identification after condensation builds up, or tip over during aliquoting. Then spend extra time checking every sample manually. Skip all of that."

Every Biofargo 0.5 mL External Thread Cryotube is designed for secure cryogenic storage, efficient low-volume sample handling, and organized laboratory workflows: a sterile polypropylene cryogenic vial featuring a green flat external screw cap, self-standing base, and integrated white writing area for direct sample marking. The compact 0.5 mL format is ideal for precious or limited-volume samples, while the colored cap design improves freezer organization and rapid visual identification.

The self-standing bottom enhances stability during aliquoting and sample preparation workflows, while the external thread structure minimizes contamination risk within the sealing area and supports dependable leak resistance during cryogenic storage and transport. Manufactured from durable medical-grade polypropylene (PP), the tubes maintain structural integrity across repeated freeze–thaw cycles and routine ultra-low temperature laboratory operations.

Compatible with standard cryogenic storage racks, cryoboxes, and laboratory freezer systems for 0.5 mL cryotubes.

Features

● Compact 0.5 mL Format — Ideal for low-volume aliquots, valuable samples, and space-efficient cryogenic storage workflows.
● Integrated White Writing Area — Screen-printed marking panel supports direct handwriting and improves tube identification during freezer storage workflows.
● Green Flat Cap for Organized Sample Sorting — High-visibility colored cap improves freezer organization and simplifies sample grouping in laboratory workflows.
● External Thread, Cleaner Sealing Area — External cap structure reduces direct sample contact with the sealing interface and supports contamination control.
● Self-Standing Bottom — Stable freestanding structure minimizes tipping during filling, labeling, and sample preparation workflows.
● Cryogenic Storage Ready — Designed for ultra-low temperature storage and repeated freeze–thaw handling in research and biobanking applications.
● RNase/DNase-Free, Endotoxin ≤ 0.005 EU/mL — Sterile, gamma-irradiated. Suitable for molecular biology and clinical research workflows.
● Bulk Packaging for Laboratory Throughput — Supplied as 100 tubes/box and 30 boxes/case for efficient inventory management and large-scale sample handling.
