Hi Si laboratory is a vendor of scientific glass founded in 2008. After 40 years of developing advanced glass products, Hi Si Glass was created to exceed the standards already set in the industry. With medical patients in mind, Hi Si designs its glassware to reduce health risks associated with high temperature smoke. This led to their creation of the geyser perc, which allows for maximum cooling, easy draw, and durability. All Hi Si Glass pipes are made using the highest quality German glass downstems and joints.
