主要特点

1. 星形脚（Starfoot）自立防旋转底座：可直立放置；冻存盒内卡位锁定，防止管子转动，方便单手开盖操作，样本定位稳定。
2. 内旋硅胶垫圈密封结构，密封性优良，降低样本挥发、泄漏风险；管身预留大面积书写标记区，便于样本编号溯源。
3. 耐宽温区间，可 4 ℃冷藏、‑20 ℃、‑80 ℃超低温、液氮气相‑196 ℃保存；禁止直接浸泡在液氮液相，如需液相保存必须配套 CryoFlex 热缩套管。
4. 无 DNase/RNase、无热原，原材料无细胞毒性、无致突变性，适配细胞冻存、血清、体液、生物样本库；符合 IATA 样本运输、欧盟 CE 诊断样本存储要求。
5. 一次性使用，不建议高压灭菌。

下游应用

哺乳动物细胞、干细胞冻存；血清、血浆、体液样本低温保存；生物样本库样本归档；科研样本低温运输。

储存条件

室温干燥避光存放；为一次性低温耗材，不可高压灭菌。

⚠️重要警告：不可直接浸入液氮液相；液相液氮环境需使用 Nunc CryoFlex 热缩套管，避免管内进液氮升温发生爆管风险。

English Product Introduction

Product Description

Nunc™ CryoTubes™ (Cat.No.377267), 1.8 mL, internal‑thread cap, round bottom with star‑foot anti‑rotation self‑standing base. Tube and cap are polypropylene (PP) with silicone sealing gasket. Gamma‑irradiated sterile, DNase‑/RNase‑free, non‑pyrogenic, non‑cytotoxic, USP Class‑VI compliant, with writing area. Temperature range:‑196 ℃ (LN₂ vapor phase) to +135 ℃. Suitable for cryopreservation of cells, serum and biological biobank samples; IATA‑compliant for biological‑sample shipping.

• Catalog No.: 377267
• Nominal volume: 1.8 mL
• Thread type: Internal thread
• Bottom: Round, star‑foot self‑standing anti‑rotation base
• Dimension: Ø12.5 mm, height 49 mm
• Pack size: 50 tubes per inner bag, total 1800 per case
• Sterilization: Gamma irradiation (SAL 10⁻⁶)
• Material: Tube & cap: PP; sealing gasket: silicone

Key Features

1. Star‑foot self‑standing anti‑rotation base: Stands upright; locks in cryobox to prevent tube rotation, enables one‑hand cap‑opening for stable sample positioning.
2. Internal‑thread cap with silicone gasket for reliable sealing, minimizing sample evaporation and leakage. Large printed writing zone for sample labelling and traceability.
3. Broad temperature tolerance for +4 ℃,‑20 ℃,‑80 ℃ and liquid‑nitrogen‑vapor‑phase storage at‑196 ℃. Do NOT immerse directly in liquid‑nitrogen liquid phase; use CryoFlex tubing for liquid‑phase LN₂ storage.
4. DNase‑/RNase‑free, non‑pyrogenic, non‑mutagenic raw materials. Compliant with IATA shipping regulations and CE marking for diagnostic sample storage in EU.
5. Single‑use only. Do not autoclave.

Applications

Cryopreservation of mammalian cells and stem cells; long‑term storage of serum, plasma and body fluids; biobank sample archiving; low‑temperature shipment of research samples.

Storage

Store at room‑temperature in dry and dark place. Single‑use consumable; autoclaving is prohibited.

Warning: Risk of vial rupture if liquid nitrogen enters the tube. CryoFlex heat‑shrink tubing is mandatory for liquid‑phase LN₂ immersion.
