ConductScience Cryogenic Vials 2.0mL with external thread provide reliable sample storage at ultra-low temperatures down to -196°C. These self-standing vials feature external threading that prevents contamination during storage and retrieval operations. The sterile design supports critical sample preservation requirements in research and clinical applications.
The external thread configuration eliminates the risk of contamination that can occur with internal threaded designs, as the sample cannot contact the threading mechanism. The 2.0mL capacity accommodates standard aliquot volumes for biological samples, cell cultures, and other temperature-sensitive materials requiring long-term cryogenic storage.
How It Works
Cryogenic storage relies on the principle that extremely low temperatures dramatically slow molecular motion and enzymatic activity, effectively suspending biological processes. At -196°C (liquid nitrogen temperature), cellular metabolism ceases and protein degradation is virtually eliminated, allowing long-term preservation of biological materials.
The external thread design prevents contamination by ensuring that the sample never contacts the threading mechanism during storage or retrieval. The thread engagement occurs outside the sample compartment, maintaining sterility of the stored material. The self-standing feature provides stability during handling and reduces the risk of sample loss due to vial tipping.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Threading Design | External threading prevents sample contamination | Many standard vials use internal threading | Eliminates risk of sample contact with threading surfaces that could harbor contaminants |
| Base Design | Self-standing base for stability | Conical bottom designs require rack support | Reduces handling complexity and spillage risk during sample preparation |
| Temperature Range | Withstands -196°C for liquid nitrogen storage | Standard vials may have higher temperature limits | Enables direct liquid nitrogen storage without risk of failure |
| Sterility | Pre-sterilized for immediate use | Some vials require user sterilization | Saves preparation time and ensures consistent sterility |
These vials combine external threading for contamination prevention with self-standing design for handling convenience. The sterile packaging and cryogenic temperature tolerance support critical sample storage applications.
Practical Tips
Allow vials to equilibrate to room temperature gradually before opening to prevent condensation formation.
Why: Rapid temperature changes can cause moisture condensation that may compromise sample integrity.
Always wear cryogenic gloves and safety glasses when handling vials stored in liquid nitrogen.
Why: Direct contact with cryogenic temperatures can cause severe frostbite injuries.
Inspect vials for stress cracks before each use, especially after multiple freeze-thaw cycles.
Why: Thermal stress can create hairline cracks that may lead to contamination or sample loss.
Fill vials to no more than 80% capacity to allow for thermal expansion during freezing.
Why: Overfilling can cause vial cracking or cap displacement during the freezing process.
Record exact fill volumes and storage dates for each vial to track sample history.
Why: Accurate records enable proper sample management and traceability for research integrity.
If caps become difficult to remove after storage, allow brief warming at room temperature.
Why: Thermal contraction can increase cap tightness, making removal easier after slight warming.

Compliance
What is the maximum storage duration at -196°C?
Storage duration depends on sample type rather than vial limitations. The polypropylene construction maintains integrity indefinitely at cryogenic temperatures.
Can these vials be used with automated liquid handling systems?
The self-standing design and standard dimensions are compatible with most automated systems, though specific robot compatibility should be verified.
How does external threading prevent contamination?
External threads keep the sealing mechanism outside the sample compartment, preventing sample contact with threading surfaces that could harbor contaminants.
Are the vials suitable for repeated freeze-thaw cycles?
The polypropylene material tolerates multiple thermal cycles, though repeated cycling may affect sample integrity depending on stored material.
What labeling materials are compatible at cryogenic temperatures?
Cryogenic-grade adhesive labels or direct printing with solvent-resistant inks are recommended for permanent identification.
Can samples be stored in vapor phase liquid nitrogen?
Yes, the vials are suitable for both liquid and vapor phase storage at -196°C temperature range.
