3. 进口医用原生聚丙烯，低温下韧性优异，长期 - 80℃、液氮气相储存不易脆裂漏液
4. 原料无细胞毒性、无致突变，满足 IVD 诊断样本储存要求，适合基因组、转录组样本长期保存
5. 适配标准冻存盒，兼容自动化样本库管理系统

适用场景

细胞株低温冻存、原代细胞保存、血液 / 组织分离样本冻存、生物样本库建库、核酸样本长期低温保存、临床生物样本归档。

English Introduction

Catalog No.: 337516 (also known as 337516PK) Brand: Thermo Scientific™ Nunc™ Name: Nunc Biobanking and Cell Culture Cryogenic Tubes, 4.5 mL, external thread, self-standing round base, with writing area

Specifications

• Tube: Virgin medical grade Polypropylene (PP); Cap: Polyethylene (PE)
• Volume: 4.5 mL; Bottom: Round self-standing starfoot anti-rotation (A-R) base
• Thread: External thread design
• Temperature range: +4 ℃ to -196 ℃ (vapor phase liquid nitrogen). Not recommended for direct immersion in liquid LN₂.
• Sterilization: Gamma irradiation, SAL=10⁻⁶; RNase-free, DNase-free, non-pyrogenic, non-cytotoxic, BSE/TSE free
• Marking: Large white printed writing area on tube body
• Packaging: 50 tubes/sleeve; 300 tubes/pack; 1200 tubes per case

Key Features

1. Self-standing star-shaped anti-rotation base, tubes can stand upright on bench without rack; prevents tube spinning during cap twisting.
2. External thread design minimizes contamination risk during aseptic manipulation, ideal for biobank and primary cell sample handling.
3. Virgin medical-grade polypropylene maintains toughness under ultra-low temperature, resistant to cracking and leakage during long-term storage at -80℃ or LN₂ vapor phase.
4. Non-cytotoxic and non-mutagenic raw materials, compatible with IVD diagnostic sample storage, suitable for long-term preservation of genomic and transcriptomic samples.
5. Compatible with standard cryoboxes and automated biobank systems.

Applications

Cryopreservation of cell lines, primary cell banking, storage of blood / tissue derived samples, biobank repository construction, long-term preservation of nucleic acid samples, clinical biosample archiving.
