产品特点

1. 内旋盖 + 内置硅胶密封圈，低温环境密封性能优异，有效防止液氮渗入、样本泄漏，适合长期超低温归档；内旋设计，降低开盖时手套接触管口污染样本的风险。
2. Starfoot 星型 A-R 防旋转自立底座，可直接直立放置于操作台；拧盖时管体不会旋转，单人操作便捷，适配标准冻存盒与自动化样本库设备。
3. 医用级原生聚丙烯，低温韧性优异，长期 - 80℃或液氮气相储存不易脆裂，保护珍贵生物样本。
4. 洁净车间生产，无核酸酶、无热原，满足基因组、转录组、多组学临床生物样本保存需求，符合生物样本库建库规范。
5. 兼容各类自动化样本存储、扫码管理系统。

适用场景

细胞株与原代细胞冻存、临床活检组织 / 血液 / PBMC 样本分装保存、生物样本库长期归档、多组学标志物样本保藏、临床诊断样本低温存储。

区分同系列：379146 内旋、锥形自立星脚；337516 为 4.5mL 外旋自立冻存管，二者螺纹方向不同，不要混淆；363452 为内旋普通圆底（非星脚）版本。

English Introduction

Catalog No.: 379146 (also known as 379146PK) Brand: Thermo Scientific™ Nunc™ Name: Nunc Biobanking and Cell Culture Cryogenic Tube, 4.5 mL, internal thread, self-standing conical starfoot A-R base with writing area

Specifications

• Material: Virgin medical grade Polypropylene (PP); internal cap with silicone gasket
• Volume: 4.5 mL; bottom: Conical self-standing starfoot anti-rotation A-R base
• Thread: Internal thread with silicone sealing gasket
• Temperature range: +4 ℃ to -196 ℃ (vapor phase liquid nitrogen). Not 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 writing area on tube body
• Dimensions: OD 12.5 mm, height 92 mm
• Packaging: 300 tubes per pack (379146PK); 1200 tubes per case

Key Features

1. Internal thread cap with integrated silicone gasket provides reliable sealing under ultra-low temperature, prevents LN₂ ingress and sample leakage for long-term cryoarchiving. Internal thread design reduces contamination risk from glove contact during cap opening.
2. Starfoot anti-rotation self-standing A-R base enables upright placement on bench; prevents tube twisting during cap manipulation. Compatible with standard cryoboxes and biobank automation systems.
3. Virgin polypropylene maintains high toughness under cryogenic conditions, resistant to cracking at -80 ℃ and LN₂ vapor phase for valuable biosample protection.
4. Manufactured in cleanroom, nuclease-free and endotoxin-free, suitable for genomic, transcriptomic and multi-omics clinical biosample banking.
5. Compatible with automated biobank storage and barcode tracking systems.

Applications

Cryopreservation of cell lines and primary cells, aliquot & archiving of clinical biopsies, blood and PBMC samples, long-term biorepository storage, multi-omics biomarker sample preservation and diagnostic biosample archiving.
