主要特点

1. 高强度聚丙烯材质，耐受高转速离心；边缘密封螺帽，颠倒混匀、高速离心不易漏液，保护珍贵样本。
2. 管身印刷清晰体积刻度，超大书写标记区域，便于样本编号溯源。
3. 配套可折叠可回收塑料支架，区别传统泡沫支架，粉尘颗粒污染风险更低；闲置可折叠收纳，节省柜内空间，支架可重复使用Avantor。
4. 高洁净等级，无核酸酶、低内毒素，适配细胞培养、核酸提取、蛋白纯化等敏感实验。
5. 一次性耗材，禁止高压灭菌重复使用。

下游应用

细胞离心收集沉淀；菌体沉淀；核酸、蛋白样本制备；试剂配置分装；生物样本暂存；分子与细胞生物学样本前处理。

储存条件

室温干燥避光存放；一次性使用，禁止高压灭菌。

⚠️提示：17000×g 额定值需要转子完整支撑；悬空放置离心必须降低转速；支架仅用于放置，不可放入离心机。

English Product Introduction

Product Description

Nunc 50 mL sterile conical centrifuge tubes (Cat.No.339653). Tube body of polypropylene (PP), blue HDPE screw‑cap, supplied with collapsible recyclable plastic rack. Gamma‑irradiated sterile (SAL 10⁻⁶), RNase‑/DNase‑free, non‑pyrogenic, non‑cytotoxic, USP Class VI certified. Maximum RCF up to 17000 × g (full rotor support). Printed graduations and large marking‑writing area on tube wall; edge‑sealed leak‑proof screw cap. Collapsible reusable plastic rack is included. Widely applied for cell pelleting, nucleic‑acid & protein sample processing, reagent preparation and temporary sample storage in molecular‑ and cell‑biology experiments。

• Catalog No.: 339653

• Max RCF: 17000 × g (full conical rotor support)
• Sterilization: Gamma‑irradiation, SAL 10⁻⁶
• Quality: DNase‑/RNase‑free, non‑pyrogenic, non‑cytotoxic, TSE/BSE‑free, USP Class VI biocompatibility grade

Corresponding bulk non‑racked version: Cat.No.339652, identical tube physical parameters, different packaging only.

Key Features

1. High‑strength polypropylene tolerates high‑speed centrifugation. Edge‑sealed screw cap prevents leakage during centrifugation and repeated inversion to protect valuable samples.
2. Clear printed volume graduations and extra‑large writing area facilitate sample labelling and traceability.
3. Equipped with collapsible recyclable plastic rack, lower particle‑contamination risk compared with traditional foam racks. The rack can be folded for compact storage and reused in lab workflowsAvantor.
4. Ultra‑clean grade, nuclease‑free and low‑endotoxin, compatible with nuclease‑sensitive workflows including cell culture, nucleic‑acid extraction and protein purification.
5. Single‑use consumable. Do not autoclave.

Applications

Cell harvesting and pelleting; bacterial pellet collection; nucleic‑acid and protein sample preparation; reagent aliquoting; temporary biological‑sample storage; pre‑treatment workflows for molecular and cell biology.

Storage

Store at room‑temperature in dry and dark environment. Single‑use only, autoclaving prohibited.

Note: 17000 × g rating requires full rotor support; reduce RCF if tubes are not fully seated. The plastic rack is for bench‑top holding only, cannot be placed into centrifuge.
