how long does it take to get the cap cold with dry ice?

I can't answer this question as I did not use dry ice. The hospital has a freezer for this purpose and I deliver my caps 48 hours before each treatment.

how long does it take to refreeze after use in a biomedical freezer? I want to reuse my caps during a 4 hour infusion.

Re: Hypothermia Cap: I would get the dry ice the night before you are going to use the cap, and keep the caps in the dry ice overnight. The caps will be super cold for your first use. If you have 4 or more caps, you can put the cap from your head back into the dry ice when you switch caps after 1/2 hour. When you go through your caps and get back to the original cap, it won't be as cold the 2nd time around. In the dry ice, the caps do get cold quickly.

The base the silicone molds are attached to is hollow, so there's no solution in the base to freeze.. The instructions say fill, then freeze at zero degrees for at least 6 hours. I'm sure freezing time varies depending on your freezer and probably the substance you're trying to freeze, but you won't have a popsicle in 10 minutes.

I believe that the instructions said to put it in the freezer overnight. 15 minutes is about how long it will stay effectively cold. It is much better for moist heat. 75 seconds in the microwave for 30 minutes of moist heat.

You will need something colder than just ice. The idea is to "freeze" it. Something that cannot be achieved with just a cooler with ice. After taking it out of the freezer it will last 30~40 min.

Hello...I find that the ice to water ratio dictates how long ice stays in the bottle...more ice...gets you closer to the 24 hour mark. I gotta say, even when the ice is gone, the water is still nice and cold.

If you had a 4 oz room temperature bottle. But for a larger volume that is cold it will take a couple of minutes and there is a learning curve on how much water to put in. Big downside is that if you don't get the bottle warm enough, the warmer needs to cool down before you can use it again. I have to run cold water in it to speed up the process. I wouldn't buy this warmer again.

In the owners manual that comes with your machine it suggest that you chill the metal cylinder, and the beverage that your going use. I've put the metal cylinder in the freezer and have not waited or very long for whatever I'm going to have to slush up.

Depends on your time frame and ambient temperature. It is not better or worse that other similar coolers on the market. If you are serious about keeping stuff frozen for more than a few hours you are going to need to pack with dry ice or invest in a freezer that can run off a car battery. For my purposes it keeps milk and meat cold for several days but I change put the ice every 48-72 hrs depending on how hot it is.

If you were to place the item in a regular refrigerator, depending upon the temperature setting, the item would freeze within 1 to 1-1/2 hours; otherwise, if you were to use a conventional or deep freezer, the item would freeze within 20 to 30 minutes.

It depends on how long the ice pack has been in the freezer before it is used. The ice pack had been in the freezer for two days when I used it the first time and after an hour it was still partially "frozen."

It gets cold very quickly, 20 minutes will do but it doesn't stay cold for very long. I've found the best time window is 2 hours in the freezer. I love this ice pack!

I have never use the product within 5-6 hours of use, but I would say that it probably takes about 2-3 hours to get "completely" cold again

I am sure this will vary....but when fully thawed it takes ours about 2 hours to freeze.

about 6 hours. I put the ice pack in the bottom, in the zipper part. It would stay cold longer it it was actually in with the food. I am not a huge fan of the compartment style.

10-20 minutes. With the compression it'll feel colder than it really is. Put a thin towel like a washcloth on your leg so that the ice pack isn't directly on your skin your first time to determine your tolerance.

It depends upon the outside temperature and the temperature of the water when you add the ice. The manufacturer says 18 hours and I have had it last that long in my air conditioned home. I have had it last 24+ hours in the fridge. But, in warmer settings, 6 -12 hours is more realistic. To maximize the time, start with a cool bottle (running cold water into it or even keeping it in the fridge). Then, use ice plus COLD water from the fridge (otherwise the warm water will melt the ice before the outside air gets a chance). Then, try to minimize time in direct sunlight. Using a room temperature bottle, plus cold water and only about 4 ice cubes, my bottle keeps at least some ice for the entire 10+ hours of my commute plus workday (desk work).

Yes, use rock salt and ice and churn for 25 to 30 minutes. Most freezers begin to groan as the ice cream makes. This one is powerful enough not to.
