Understanding the Key Specifications

Cryovial Capacity

Indicates the number of cryovials a tank can accommodate with a specified internal storage configuration. Capacity varies according to vial dimensions, rack design, and the selected model.

Neck Opening

Determines the opening available for sample access and constrains the dimensions of compatible racks, canisters, and other internal components.

Static Evaporation Rate

Measures natural liquid nitrogen loss under specified test conditions. It is useful for comparing models, but does not directly represent actual daily consumption under every operating condition.

Static Holding Time

Indicates the reference holding time measured under specified conditions. It should not be treated as a guaranteed refill interval in routine laboratory use.

How to Choose the Right Lab dewar?

The right laboratory dewar mainly depends on the number and type of samples you need to store. TcCryo laboratory dewars offer different rack configurations for different sample quantities.

30L–50L Models

These models feature 5×5 rack configurations and are suitable for laboratories with smaller sample collections.

65L–210L Models

These models support 9×9 or 10×10 rack configurations, providing more storage positions for larger sample collections.

Storage Options for Different Sample Containers

In addition to 2ml cryovials, these dewars can be configured for other sample containers, such as 5ml cryovials. Customized internal configurations are also available for blood bag storage.

Optional Accessories for Daily Useg

Liquid-level alarms and smart monitoring caps are available for all models to help monitor liquid nitrogen levels.Tank carts are also available. 30L–50L models use X-type carts, while larger models use flat-platform carts.

Use & Safety Guidelines

Follow these precautions when handling and using a laboratory liquid nitrogen tank.

Ensure Adequate Ventilation

Use liquid nitrogen tanks in adequately ventilated areas. Evaporating nitrogen gas can displace oxygen and create an oxygen-deficient atmosphere.

Wear Appropriate Protective Equipment

Wear suitable cryogenic gloves and eye protection when filling or handling liquid nitrogen. Use a face shield when required by applicable safety procedures.

Keep Venting Paths Unobstructed

Never seal a liquid nitrogen storage container or block its designed venting and pressure-relief paths.

Use Appropriate Handling Equipment

Use a compatible trolley or handling system when moving the dewar. Keep it upright and avoid impacts or sudden movements. Follow the manufacturer's instructions for moving a filled or empty container.

Inspect the Tank and Accessories

Regularly check the vessel, neck opening, lid, and accessories for visible damage or abnormal conditions. Contact the manufacturer if any unusual condition is observed.

Follow the Product Manual

Always follow the manufacturer's instructions for filling, operation, inspection, and maintenance.

Frequently Asked Questions

Q1: Should I choose a conventional liquid nitrogen storage tank or a vapor-phase cryogenic freezer for biological sample storage?

The right choice depends on your sample type, storage protocol, temperature requirements, container configuration and contamination-control needs. A conventional liquid nitrogen storage tank may be suitable for liquid-phase storage, where samples are immersed in liquid nitrogen. A vapor-phase cryogenic freezer is worth considering when samples need to be stored above the liquid nitrogen level to avoid direct contact with the liquid. Contact TcCryo with your sample type and storage requirements for model selection assistance.

Q2: Can a liquid-level monitoring device be installed on an existing liquid nitrogen dewar?

Yes. TcCryo offers liquid-level alarms and smart monitoring caps for compatible liquid nitrogen dewars. Contact us with your tank model and neck opening dimensions so we can recommend the appropriate monitoring device.

Q3: Can I use storage racks or canisters from another brand with a TcCryo lab dewar?

Not necessarily. Compatibility depends on the dewar's neck opening and internal dimensions, as well as the dimensions and support structure of the existing racks or canisters. Provide the relevant product specifications or measurements so compatibility can be checked before purchase.

Q4: Can a liquid nitrogen storage container be moved within the lab?

Some laboratory dewars can be moved using a compatible trolley or handling system. Before moving a container, check its dimensions, weight, base design and compatibility with the handling equipment. Always follow the manufacturer's handling instructions and applicable safety procedures. Do not drag or tilt a container unless the model-specific instructions explicitly permit it.

Q5: Does TcCryo support OEM/ODM orders for distributors, and what are the typical lead times?

Yes. TcCryo supports OEM/ODM cooperation and product customization for distributors. Lead times depend on the selected model, order quantity, stock availability and customization requirements. Contact our sales team with your specifications and estimated order volume for a quotation and delivery schedule.
