The present utility model relates to a glass cabinet attached at the back of an air-conditioning unit with an exhaust system built on top of the cabinet so designed to prevent overheating of the said unit. The assembly of the aforementioned utility model is developed for drying laboratory apparatuses and generating alternate distilled water source. The said glass cabinet was installed with two glass sliding doors for better access. Inside the cabinet is a drying rack where laboratory apparatus can be laid upon and dried. The by-product of the air-con which is the condensed water is filtered through a plastic funnel using filter paper and collected to empty distilled water containers for storage. The stored condensed water generated from the unit can now be used in some laboratory equipment namely water bath, rotary evaporator, autoclave, and other equipment that requires distilled water as a heating medium. The utility model is being tested in terms of its efficiency in drying time and volume of distilled water collected per unit time and water purity through a series of physico-chemical test.
