Hexagonal Bottom Internal Thread Cryogenic Tube

Updated: 2026-09-11

Overview

The Hexagonal Bottom Internal Thread Cryogenic Tube is a precision-engineered laboratory tool designed for the safe storage of samples at extremely low temperatures. Its hexagonal base provides enhanced stability, reducing the risk of tipping during handling, while the internal thread ensures a secure and leak-proof seal with compatible caps. This tube is widely utilized in research laboratories, biobanks, and pharmaceutical industries where maintaining sample integrity at cryogenic temperatures is critical. The design of the tube addresses common challenges in cryogenic storage, such as thermal shock resistance and ease of handling. Available in various materials like borosilicate glass and polypropylene, it caters to diverse application needs, from biological sample preservation to chemical storage.

Structure and Working Principle

The Hexagonal Bottom Internal Thread Cryogenic Tube features a cylindrical body with a hexagonal base, which prevents rolling and enhances stability on flat surfaces. The internal threading allows for a tight seal with screw caps, minimizing the risk of sample contamination or evaporation. The tube's walls are engineered to withstand extreme temperature fluctuations, ensuring durability in cryogenic environments. When used in liquid nitrogen or ultra-low freezers, the tube's material properties play a crucial role in preventing thermal cracking. Borosilicate glass variants offer high transparency and chemical resistance, while polypropylene tubes provide flexibility and impact resistance. The internal thread design ensures compatibility with a range of sealing mechanisms, making it versatile for different laboratory setups.

Key Features

The Hexagonal Bottom Internal Thread Cryogenic Tube stands out due to its unique combination of stability, sealing efficiency, and thermal resistance. The hexagonal base design is particularly beneficial in high-throughput labs where tubes are frequently handled or stored in racks. The internal thread ensures a hermetic seal, critical for maintaining sample integrity over long periods. Additionally, the tube's material options allow users to select the most suitable variant for their specific needs. For instance, stainless steel tubes are preferred for their robustness and reusability, while disposable polypropylene tubes are cost-effective for single-use applications. The tubes are also often marked with graduations or labeling areas for easy identification and measurement.

Application Areas

This cryogenic tube is indispensable in various scientific and industrial fields. In biotechnology and medical research, it is used to store cell cultures, DNA samples, and vaccines at ultra-low temperatures. Pharmaceutical companies rely on these tubes for the preservation of drug formulations and reference standards. Chemical laboratories utilize the tubes for cryogenic reactions and the storage of sensitive reagents. The tubes' leak-proof design and thermal stability make them suitable for long-term storage in liquid nitrogen dewars or ultra-low temperature freezers, ensuring sample viability and consistency.

Maintenance and Precautions

Proper maintenance of Hexagonal Bottom Internal Thread Cryogenic Tubes is essential to ensure their longevity and performance. Regular inspection for cracks or wear, especially in glass variants, is recommended. Tubes should be cleaned with appropriate solvents and dried thoroughly before reuse to prevent contamination. Precautions include avoiding rapid temperature changes, which can cause thermal stress and cracking. When sealing the tubes, ensure the caps are threaded correctly to prevent leaks. For storage in liquid nitrogen, use protective gloves and handle tubes with care to avoid frostbite or accidental breakage.

B2B Procurement Guide

When procuring Hexagonal Bottom Internal Thread Cryogenic Tubes in bulk, consider factors such as material compatibility with stored samples, thread specifications, and temperature resistance. It's advisable to request samples for testing sealing efficiency and durability under intended conditions. Suppliers often provide customization options, such as pre-labeled tubes or specific thread designs. Comparing prices from multiple vendors and checking certifications for quality standards can help in making an informed purchase decision. Bulk orders may qualify for discounts, so negotiate terms based on volume requirements.
