Every liquid nitrogen user eventually faces the same question: what is the right way to receive and store it? Too small a format means constant refilling and handling; too large means paying for capacity and infrastructure you do not need. This guide compares the three main liquid nitrogen supply options: liquid nitrogen containers, liquid cylinders and bulk tanker supply into on-site storage, so you can choose the format that fits your usage.
The Three Options at a Glance
| Liquid nitrogen containers | Liquid cylinders | Bulk tanker supply | |
|---|---|---|---|
| What it is | Open-neck, non-pressurised vacuum-insulated vessels | Closed, pressurised vacuum-insulated vessels with valves | Liquid nitrogen delivered by road tanker into a storage tank on site |
| Size at Spectra | 1 L to 51 L | 180 L to 240 L (supplied as a distributor) | Tanker quantities of 6,000 L and 13,000 L; minimum order 2,000 L |
| Main use | Storing samples; small quantities of liquid | Supplying liquid or gas; on-site reservoir | Steady, higher consumption |
| Holding time | Typically 15 to 60 days, depending on model | Depends on model and use | Depends on tank and consumption |
| How liquid is used | Items stored inside; liquid poured when needed | Drawn off through valves as liquid or, depending on design, gas | Drawn from the storage tank to the point of use |
| Site needs | Ventilated storage space | Ventilated floor space; handling equipment | Space for a storage tank and safe tanker access |

Option 1: Liquid Nitrogen Containers
Liquid nitrogen containers, also called cryocans or dewars, are the most familiar format. They are open-neck, non-pressurised vessels designed to keep liquid nitrogen, and the samples stored in it, at cryogenic temperature.
Best suited to:
- storing biological samples and other materials at cryogenic temperature;
- users who need small quantities of liquid nitrogen;
- work in several locations, or field use, where vessels need to be carried.
Things to consider: containers must be refilled before they run low, and each refill involves handling open liquid. Spectra’s containers range from 1 L to 51 L, with holding times typically between 15 and 60 days depending on the model.
Option 2: Liquid Cylinders
Liquid cylinders are closed, pressurised vacuum-insulated vessels fitted with valves, gauges and pressure-relief devices. They hold far more than a portable container and deliver liquid or gas through their valves.
Best suited to:
- sites that refill several containers and want an on-site reservoir;
- processes that need a regular supply of liquid or gas;
- users whose consumption is too low or irregular to justify a bulk tank.
Things to consider: a filled cylinder is heavy and needs suitable handling equipment, ventilated floor space and staff trained on its valves and relief devices. Spectra supplies liquid cylinders from 180 L to 240 L as a distributor.
Option 3: Bulk Tanker Supply
For sites with steady, higher consumption, bulk liquid nitrogen supply by road tanker into an on-site storage tank is usually the most practical approach. Instead of handling many smaller vessels, the site receives larger deliveries and draws liquid nitrogen from the tank as needed.
Best suited to:
- industrial processes such as cryogenic grinding, food processing and cooling;
- hospitals, laboratories and other facilities with significant, regular usage;
- sites that want to reduce manual handling of small vessels.
Things to consider: bulk supply needs a suitable storage tank, space and safe access for the tanker. Spectra supplies bulk liquid nitrogen by tanker across India, in quantities of 6,000 L and 13,000 L, with a minimum order of 2,000 L.

How to Choose: Five Questions
1. Are You Storing Samples or Using Liquid Nitrogen?
If you need to keep samples frozen, you will need containers designed for storage, whatever else you use. If you need the liquid itself, cylinders or bulk supply are usually more practical.
2. How Much Do You Use, and How Regularly?
Small, occasional use suits containers. Regular, moderate use often suits liquid cylinders. Steady, higher use points towards bulk tanker supply.
3. Do You Need Gas as Well as Liquid?
Containers supply liquid only. Liquid cylinders, depending on their design, and bulk systems can be set up to supply gas as well.
4. What Space and Access Do You Have?
Bulk supply needs room for a storage tank and safe tanker access. Cylinders need ventilated floor space and a route for moving them. Containers need a ventilated storage area.
5. How Much Handling Do You Want?
Each step up, from containers to cylinders to bulk, generally reduces the amount of manual handling of open liquid.
Combining Formats
Many sites use more than one format. A laboratory might keep samples in containers and refill them from a liquid cylinder. A processing plant might use bulk supply for production and keep containers for smaller tasks. Choosing the right combination is often more important than choosing a single format.
Safety Applies to Every Option
Whatever format you choose, liquid nitrogen should be stored and used in well-ventilated areas, vessels should never be sealed in a way that traps evaporating gas, and staff should use suitable cryogenic PPE when filling and handling it.
