Mushroom spores need special storage conditions in order to be kept for a long time. Although they can be kept in a cool, dark place for somewhat longer periods of time, the best way to store them is in the refrigerator. At any rate, they should not be frozen, as this can deteriorate the syringes, and thus make it difficult for them to be studied under the microscope.
Apparently, a good quality spore syringe can exist in the fridge for four to twelve months. Nevertheless, some scientific researchers have declared that they kept spore syringes in the refrigerator for even longer periods, and the microscopic research went on very well.
The variables regarding the exact period for which you can keep spore syringes in the fridge may depend on the exact ingredients found in the solution.
After the research is performed, the syringe should be sterilized with the help of an alcohol-based wipe. In order to prevent leaks, the syringe cap should be carefully secured. After that, the syringe must be placed in a plastic bag, preferably sealed after removing air. And when you want to use the spore syringe again, all you need to do is remove the cap and start over.
