Synthetic urine can be frozen.

However, the temperature of the water (heating or cooling) to which synthetic urine is mixed may need to be adjusted accordingly: in order for synthetic urine’s effectiveness not to decrease, the mixture should have a normal body temperature when introduced into testing equipment.

Synthetic urine also has a shelf life and eventually expires.

If the synthetic urine will be frozen, it should be stored at a temperature of -20° Celsius (-0.003048 degrees Fahrenheit) before being placed in a freezer set to 0° Celsius (32.1436 degrees Fahrenheit).

This can allow for up to one year’s worth of storage time without any issues.

How to Freeze Synthetic Urine?

Some people like to freeze their synthetic urine so that they can take it on the go with them. You have two options in how you want to do this:

  • Freeze the entire bag of synthetic urine and store it for a few hours or days until you need to use it
  • Put your frozen urine into an insulated container (such as a cooler) to keep it frozen for up to 24 hours

Once you have your container ready, place the synthetic urine into it and close the lid. This will help protect the contents from external heat sources which can cause them to defrost faster than desired.

When you need to use the frozen synthetic urine just take it out of your container and allow the material to thaw before using.

You will want to put your fingers in a cup or bowl of warm water for about 30 seconds so that they are not cold when touching the liquid once it has been freed from its icy prison.

Why You Should Consider Freezing Your Synthetic Urine?

Synthetic urine is a great way to pass a drug test. The best time for testing synthetic urine, is before you need it!

You can store the frozen sample in your freezer and then thaw it out right before taking the test.

This will allow you to make sure that there are no leaks or spills during transport. If anything goes wrong, you have an extra sample to use.

Another advantage to freezing your synthetic urine is that you can get a larger quantity.

It typically takes one ounce of liquid to fill an empty test tube for urinalysis testing.

The problem with this is that every time you have it thawed and refrozen, the volume will be reduced by at least half.

What Are the Side Effects of Freezing the Synthetic Urine?

  • The urine may be full of sediments that are frozen in the container. This can result in a cloudy, chunky or gritty mixture when you heat it up and use it to pass drug tests.
  • If your testing facility is using adulteration checks like adding an acidifier to your sample then freezing will cause this substance to be more acidic which may result in a failed test.
  • The urine may not pass the adulteration check that some facilities use because it is difficult to keep a clean sample when you are freezing and thawing it.

Synthetic urine will last indefinitely in the freezer, provided it is wrapped tightly to prevent ice crystals from forming and damaging the plastic.

The temperature of a home freezer ranges anywhere between -18°F (-28°C) and 0° F (17.78 C).

The iced synthetic urine should be brought out of the freezer for a few hours before use to allow it to thaw.

If the urine is not iced, then there are special syringe pens that can be purchased online or at some sex shops.

These will heat up and cool down in order to maintain an accurate temperature of body-temperature liquid throughout its usage duration.

Can Synthetic Urine Remain Effective After Freezing?

One common question asked about synthetic urine is whether it remains effective after being frozen. The answer is yes; synthetic urine can still function properly after undergoing the freezing and thawing processes. It’s important to note that freezing synthetic urine carries some potential risks and is generally not recommended. Additionally, freezing is unnecessary as synthetic urine kits typically have a longer shelf life compared to real human urine, even when stored at room temperature.

If you find yourself needing to store a synthetic urine kit for an extended period without a trusted brand available, freezing can be an option. Simply thaw the synthetic urine and prepare it according to the provided instructions.

Can Fake Urine Be Reheated?

You can reheat your synthetic pee if need be so long as the temperature is not higher than 131 degrees Fahrenheit or colder than 32 degrees Fahrenheit.

Synthetic urine is usually sold at room temperature, so it will not be necessary to reheat your fake pee unless you have left it out in a hot car or some other place where the temperature went above 131 degrees Fahrenheit.

How Do You Thaw and Heat Urine?A urine sample in a microwave

To thaw and heat urine you should place it in a refrigerator or microwave set to medium-high temperature for no more than 30 seconds.

Do not put the synthetic pee on full power, as this will cause too much liquid to evaporate from it which will make the mixture less accurate when used later.

You can also buy heating pads designed for this purpose that are available on Amazon.

To reheat the urine you should place it in a sealed container with boiling water for 45 minutes.

The mixture will rise to just below body temperature and you can then use it as needed.

What Is the Best Way to Store Frozen Synthetic Urine at Home or in a Car for Emergencies?

  • The best way to store frozen synthetic urine at home or in a car for emergencies is to keep it as cold and dark as possible.

Putting the container of liquid into an ice chest with other drinks will help slow down the rate that water evaporates out of the bottle, but any air space around the bottle should be minimized so that the freezer can work more efficiently.

  • Since water is responsible for most of the volume in synthetic urine, it’s important to consider how much liquid will evaporate out per day when calculating storage time.

For example, a two-liter bottle will lose about one cup of water every 24 hours. If you’re traveling and need to store synthetic urine for an emergency, plan on using it within three days.

Another time where freezing could come in handy is before giving blood, as some laboratories will not accept urine that is thawed.

  • Do not use frozen synthetic urine if you are going to be in a hot climate as this will cause the freezing process to happen too quickly.
  • If you’re in any other type of climate, it should be fine! The temperature does not affect how long your liquid is good for once thawed.

However, if you have a lab-designed drug screen it may. You can find out which type of tests your workplace uses by contacting them or looking up their website’s testing policies online.

Is it Okay to Freeze Urine for a Later Time?

One of the most common questions that people have about synthetic urine is whether or not you can store some in your freezer for later use.

While freezing won’t do any harm to the product, and many companies say their products are safe to freeze, there’s still a chance that the urine will become compromised over time.

If you’re going to freeze some, experts recommend freezing it in a sealed container with as much air removed from it as possible.

It’s also worth noting that storing synthetic urine in your freezer for too long might cause issues when using it on an inspection strip test; if there are any ice crystals in the urine, it might not work properly.

The best way to keep synthetic urine fresh is by storing it at room temperature and avoiding exposing it to high temperatures or humidity.

The product will last for up to two years if stored with these conditions, which are more than enough time for most people’s needs.

Conclusion: Should You Freeze Synthetic Urine?

Synthetic urine is a lifesaver when you need to pee for the sake of passing your drug test.

But, can synthetic urine be frozen? The answer is yes and no!

When it comes to storage, there are two types of containers that will keep your synthetic urine safely preserved until you’re ready to use it again: glass jars and plastic syringes.

Both options are great because they have been designed specially for storing liquid substances like this one.

Glass jars offer more protection against light exposure, which may degrade some ingredients in the mix (like urea).

Plastic syringes might not last as long, but they do provide an easier way to get out just what you need without having any mess left behind or risk spilling anything on yourself.
