We are thrilled to inform that after over 6 months of research we are introducing new and improved glass bottles. New bottles, covered with a special layer guarantee double the avarage shelf life – 2 years in storage. Change concerns Marquis, Mecke, Mandelin, Ehrlich and Hofmann, the most corrosive and sensitive reagents.

Glass is the golden standard for chemical storge, because it doesn’t react with reagents. Unfortunately each glass bottle has a weakness – the plastic cap. Our bottles have been specially processed in order to create an additional chemical resistant layer, which effects we show below.

To demonstrate the results we have prepared two bottles of Mecke reagent (one of the shortest lasting tests). Both were kept for 6 months upside down in room temperature and daylight. On the left you can see reagent poured from the new chemical resitant bottle, and on the right from a standard, old bottle.

Feel welcome to test it yourself!

Reagents presumptively indicate PRESENCE, but not PURITY or QUANTITY. To detect all ingredients and estimate potency it’s required to use an additional purity test kitA positive or negative test result does not indicate if the substance is safe. No substance is 100% safe.
