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 cap that you can dispense without removing it which could result in you dropping it or leaving it behind ( less things to mess with in such a situation ).
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 ,
To ensure accuracy, it is advisable to practice beforehand in order to determine the temperature after carrying the item for an hour and to confirm that it is securely positioned.
For a warm water-filled bottle, aim for a temperature range of 100 degrees Fahrenheit. To achieve this, you can briefly microwave the bottle few seconds, shake it, and then check the temperature. It is not advisable to use a warmer to heat the sample, as it would take a considerable amount of time.
The warmer is a insulating heat and body flesh regulates the temp pulling excess heat away from bottle .
It is important to note that if the temperature exceeds the range of the thermometer, it will not be displayed. If bottle feels warms to hand its probably too warm as you can't really feel body temp unless hands are cold.
The sample should be added only when you are ready to conduct the test.
Pick up extra hand warmers at walmart ( usually have 2 packs in check outs ) carry with water for an hour and walk around to see how temp holds. Carry both ways with and without to observe if temp is issue . May not need them in summer however labs keep waiting groom cold as ice for this reason .
With a dry run you will have confidence and overcome any nervous issues.
For random testing scenarios,Carry the warm water and the vial separately.
Just remove cap from vial (put cap in pocket) then insert the vial into bottle and secure cap and shake.
