Storing adhesive in sterilized lab glass
Another wonderful tip shared by SiC Polska: Instead of using chemicals for the storage of microbiologically sensitive adhesives such as starch glue, they can be preserved in sterilized vessels. In this examples small amounts were poured into mini-vessels fashioned from laboratory glass cleaned and rinsed with boiling water. The petri-dish is put on top of a glass filled with glue until a slight meniscus appears. This excess seals the edges. Once cooled down, the glasses are stored in the refrigerator. Thanks to this simple process you can keep the glue fresh for a few weeks.
