If you work in a laboratory or any other setting where you use liquid nitrogen, you'll need to know how to safely top up the liquid nitrogen in a dewar tank. Here's a step-by-step guide on how to do it.
Preparing to top up the liquid nitrogen.
Before you start topping up the liquid nitrogen in the dewar tank, make sure you have all the necessary equipment ready. You'll need to have a pair of safety gloves, safety goggles, and a liquid nitrogen transfer hose. Ensure that the area you are working in is well-ventilated to prevent the buildup of nitrogen gas.
1. Check the liquid nitrogen level.
The first step is to check the current level of liquid nitrogen in the dewar tank. You can do this by looking at the sight glass on the side of the tank. If the level is below half, it's time to top up.
2. Put on safety gear.
Safety is always the top priority when working with liquid nitrogen. Put on your safety gloves and goggles before you begin the top-up process.
Topping up the liquid nitrogen.
Once you have all the necessary equipment in place and have taken safety precautions, you can start topping up the liquid nitrogen in the dewar tank.
3. Connect the transfer hose.
Attach the liquid nitrogen transfer hose to the dewar tank. Make sure it is securely connected to prevent any leaks.
4. Open the nitrogen supply.
Turn on the nitrogen supply to start transferring liquid nitrogen from the supply tank to the dewar tank. You should see the level of liquid nitrogen in the tank rising as you do this.
5. Monitor the level.
Keep an eye on the sight glass as you top up the liquid nitrogen. Stop the transfer once the level reaches the desired point, usually around three-quarters full.
6. Disconnect the hose.
Once the tank is sufficiently topped up, turn off the nitrogen supply and disconnect the transfer hose from the dewar tank.
7. Secure the tank.
Ensure that the tank is securely closed and the lid is properly sealed to prevent any spills or leaks.
Wrapping up.
Now that you have successfully topped up the liquid nitrogen in the dewar tank, you can continue with your work knowing that you have a fresh supply of this essential cooling agent. Remember to always follow safety guidelines when working with liquid nitrogen to avoid any accidents or injuries.
