More about the Kits:
These kits are not meant to be carried around as they require time/space/good lighting to get the best from them. Whilst carrying such kits in public could arouse suspicion, if it is seen, if attending a club etc. Therefore, they are predominantly for use in safe environments, where there is good lighting etc. Hence, these kits are designed for the wiser “party-goer” who plans their night in advance. Confident they have tested their substance of choice and has a good idea that it is not Aspirin, or PMA etc.
These Reagents are designed to give you multiple tests, each holding the same amount of liquid Reagent, enabling over 75 (drop count test 16th June increased due to new fill methods) single drop tests per Reagent bottle (we always over fill so you probably get several more test). Unless you are highly skilled two drops of Reagent would be required to be able to see the colours within the required time frames. Using less may be a false economy, as you may need to repeat the test, but that is your choice.
Note: Some Reagents (3 phase Cocaine test) have a specified number of tests rather than a drop count
The kits need to be stored, in a secure, cool dark place out of reach of children when not being used. The kits do age and will age far quicker in the wrong environment. This is one reason why we do not sell larger quantities in each bottle, even though there is the room. The kits are designed to give you a high number of usable tests, relative to how often someone would undertake a test, before the product would be considered aged. A kit should be discarded after one year and replaced with a new kit.
Ideally you need to keep the reagents in a cool (fridge not freezer) dark place upright & with the lids on away from children etc. If you cannot store in a fridge for safety reasons etc (remember most reagents have a high percentage of concentrated sulphuric acid in) go cool and dark, but remember heat sources can be indirect i.e. a radiator behind a desk, or on the other side of a wall etc, whilst light and particularly sun light is a heating source as well.
Wipe any excess reagent from the nozzle or tip, due to surface tension, if bottle not inverted when dispensing.
Some of the reagents react with LDPE (plastic). This plastic is found in the nozzles of these types of bottles (glass or HDPE). The reagents do not react with HDPE or glass, however both types need the LDPE nozzle and hence some mild discolouration can occur on some reagents; particularly if the excess reagent is not removed and / or the bottles are not stored upright. Some discolouration of the nozzle can also occur. However, the reagent is still fine to test with.
Note: The reagents have a limited shelf life which can also be reduced by humidity (hygroscopic) therefore always replace caps after use.
