MTC's Autoclave & Incubator rack is made of heavy duty stainless steel that prevents rust and stands up to harsh temperatures. The rack is designed to easily fit in smaller incubators, while maintaining a capacity of 41 x 15mL or 17x100mm tubes. The rack is also fitted with PTFE feet that prevent it from scratching or damaging the inside of any autoclave or incubator. Molded handle grips keep your hands safe while removing the rack from heated chambers.
