Tips for using synthetic urine bottles

 TO insure you have a proper temperature and stress free synthetic urine substitution.
First you want a bottle that is made of the best material which is LDPE low density poly ethylene this means its a softer plastic that allows for easier heat transfer from warmer to urine and bottle to flesh. This plastic will be mostly clear and semi pliable,  as apposed to a hard white plastic. 

•   The bottle should have a easy to read thermometer label  preferably with a 2 degree offset like the collection cups use for the most accurate temp.  

• It is best to use a  dispensing cap  to fill cup  without removing it which could result in you dropping it or leaving it behind  ( less things to mess with in such a situation ).

 
Warmers
Warmer should be the smallest hand warmer with longest activation time, not anything large that will result in excess tempt issues .
An adhesive tab or rubber band to secure warmer to bottle 
 
Powdered Synthetic Urine  
All Liquid Urine contains Biocides and or peroxides  which can pop a validation screen and leave sample flat and odorless .   

Powdered Synthetic    does not need to use biocides ,

 Preparation and Temperature Practice Tips

To ensure accuracy, it’s best to practice in advance. Carry the item for about an hour to check its temperature and confirm it stays in the ideal position.
For a warm water–filled bottle, aim for a temperature of around 100°F (37–38°C). You can reach this by microwaving the bottle for a few seconds, shaking it well, and testing the temperature.

Avoid using hand warmers to heat the sample—they take too long to raise the temperature effectively. The purpose of the warmer is insulation; your body naturally helps regulate the heat by absorbing any excess warmth from the bottle.

Note: If the temperature exceeds the range of your thermometer, it may not register on the display. As a rule of thumb, if the bottle feels noticeably warm to your hand, it’s probably too hot, since body temperature can feel neutral to the touch unless your hands are cold.

Only add the sample when you are completely ready to perform the test.
For extra preparation, pick up spare hand warmers (often sold in two‑packs near checkout at Walmart). Carry the water for about an hour and monitor how well it maintains its temperature. Try it both with and without warmers to see which method works best. In summer months, you may not need warmers—but keep in mind that testing rooms at labs are often quite cold.
A dry run helps you feel confident and reduces any nervousness during the actual test.

For random testing situations, carry the warm water and vial separately. When ready, remove the vial cap (keep it in your pocket), insert the vial into the bottle, secure the cap, and shake gently.
