Ordering liquid nitrogen may seem like a daunting task, but it is actually quite simple. Liquid nitrogen is a cryogenic liquid that is used in a variety of applications, including scientific research, food processing, and medical procedures.
The first step in ordering liquid nitrogen is to find a supplier. There are many suppliers of liquid nitrogen, so it is important to compare prices and services before making a decision. Once you have found a supplier, you will need to provide them with some basic information, such as your name, address, and phone number. You will also need to specify the quantity of liquid nitrogen that you need and the delivery date.
Liquid nitrogen is typically delivered in cryogenic tanks. These tanks are designed to keep the liquid nitrogen cold and prevent it from evaporating. The tanks are also equipped with safety features, such as pressure relief valves and rupture disks. When the liquid nitrogen is delivered, the supplier will place the tank in a safe location and provide you with instructions on how to use it.
Ordering Process
The process of ordering liquid nitrogen involves the following steps:
- Identifying a supplier: Research and select a reputable supplier that offers liquid nitrogen in the required quantity and quality.
- Contacting the supplier: Reach out to the supplier via phone, email, or their website to inquire about availability, pricing, and delivery options.
- Providing specifications: Clearly specify the quantity, purity, delivery schedule, and any special requirements you have for the liquid nitrogen.
- Negotiating terms: Discuss and finalize the price, payment terms, and delivery details with the supplier.
- Placing the order: Submit a purchase order or formal order confirmation to the supplier, including all the agreed-upon details.
- Payment: Pay for the order in accordance with the agreed-upon payment terms.
- Delivery: The supplier delivers the liquid nitrogen to the specified location at the agreed-upon time.
Communication
Effective communication is crucial throughout the ordering process. Clear communication ensures that:
- Your requirements are accurately conveyed to the supplier.
- The supplier understands your needs and can provide a suitable solution.
- Any changes or updates can be promptly communicated and handled smoothly.

Storage and Transfer Considerations
Hazards of Liquid Nitrogen
Liquid nitrogen is an extremely cold liquid (-196°C) that can cause severe burns if it comes into contact with skin or eyes. It can also cause asphyxiation if inhaled in large quantities. It is crucial to take appropriate safety precautions when handling and storing liquid nitrogen.
Storage Guidelines
- Store liquid nitrogen in a well-ventilated area with good air circulation.
- Use appropriate containers, such as insulated dewars or cryogenic tanks, to minimize evaporation.
- Keep containers closed and away from heat sources.
Transferring Liquid Nitrogen
- Wear appropriate personal protective equipment, including gloves, eye protection, and a lab coat.
- Use a specialized transfer hose or pipette designed for cryogenic liquids.
- Transfer liquid nitrogen slowly to avoid splashing or spills.
Specific Storage and Transfer Considerations
| Specific Considerations | Actions |
|---|---|
| Transferring from Dewar to Dewar | Use a cryogenic transfer hose or a specialized pipette. Transfer slowly and avoid splashing. |
| Transferring from Dewar to Lab Vessel | Use a cryogenic pipette or a specialized funnel. Transfer slowly into the center of the vessel. |
| Storing in Lab Vessel | Keep the vessel closed with a suitable stopper or lid. Monitor the liquid nitrogen level regularly. |
| Disposal | Slowly vent the liquid nitrogen into a well-ventilated area. Dispose of the empty container according to local regulations. |
