Round Bottom Internal Thread Cryogenic Vial

Updated: 2026-09-24

Overview

The Round Bottom Internal Thread Cryogenic Vial is a critical tool in modern laboratories, particularly in fields requiring long-term biological sample storage. Its design combines functionality and reliability, making it a preferred choice for researchers and clinicians. The internal thread mechanism ensures a tight seal, preventing contamination and sample loss, while the round bottom facilitates easy sample retrieval. The vial's construction from high-quality polymers like polypropylene ensures durability under extreme conditions, such as immersion in liquid nitrogen. This makes it indispensable for biobanking, pharmaceutical development, and clinical diagnostics, where sample integrity is paramount.

Structure and Working Principle

The vial features a cylindrical body with an internal thread at the opening, which securely mates with compatible caps. This design minimizes the risk of cross-contamination and evaporation, even during prolonged storage. The round bottom enhances sample recovery by allowing pipettes or other tools to access the entire volume without residue. Cryogenic vials are engineered to withstand thermal shocks, maintaining structural integrity when transitioning between room temperature and ultra-low storage conditions. The materials used are non-reactive, ensuring that samples remain uncontaminated and viable for future analysis.

Key Features

One of the standout features of these vials is their internal threading, which provides a more reliable seal compared to external thread designs. This is particularly important in cryogenic applications where even minor leaks can compromise sample quality. The round bottom design is another critical feature, enabling complete sample recovery and reducing waste. Additionally, many models include graduations for accurate volume measurement and are available in sterile or non-sterile variants. The vials are also often color-coded for easy identification and may include writable surfaces for labeling.

Application Areas

Round Bottom Internal Thread Cryogenic Vials are extensively used in biobanks for storing DNA, RNA, cells, and tissues. They are also vital in pharmaceutical research for preserving drug formulations and in clinical settings for maintaining patient samples like blood and plasma. Their use extends to academic research, where they are employed in microbiology, genomics, and proteomics studies. The vials' reliability and compatibility with automated storage systems make them a staple in high-throughput laboratories.

Maintenance and Precautions

Proper handling of cryogenic vials is essential to prevent breakage and ensure sample safety. Always inspect vials for cracks or defects before use, and avoid rapid temperature changes to minimize thermal stress. When sealing, ensure the cap is tightly screwed to prevent nitrogen infiltration, which can cause vial explosion upon warming. Storage should be in upright positions within racks designed for cryogenic conditions. Regular audits of stored vials are recommended to check for any signs of degradation or seal failure over time.

B2B Procurement Guide

When procuring Round Bottom Internal Thread Cryogenic Vials in bulk, consider factors such as material certification (e.g., USP Class VI compliance for medical-grade applications) and compatibility with existing storage systems. Volume discounts are commonly available, with prices varying based on order size and customization options like pre-printed labels or barcodes. Suppliers often provide samples for testing seal integrity and thermal performance. It's advisable to establish long-term relationships with reputable manufacturers to ensure consistent quality and timely delivery, especially for critical research or clinical applications.
