The Catalyst’s tank is made from Tritan®; a medical-grade, BPA-free polymer. This food-safe polymer is the highest quality used in a fermenter, providing the clarity of glass with the durability and convenience of plastic. This material acts as an excellent barrier against oxygen, making our tank 93% more scratch-resistant than other plastic fermenters. It is dishwasher safe and withstands temperatures of up to 110°C/230°F.
