Economy manual control Tuttnauer® Model autoclaves are designed for sterilizing laboratory and medical equipment, media and even liquids. These Tuttnauer® autoclaves provide fast, safe and dependable sterilization without any need for special plumbing or venting. These laboratory autoclaves are manufactured with 316L stainless steel sterilization chambers which are highly corrosion-resistant. Autoclaves also feature a fast exhaust option which reduces cycle time for solid goods and a slow exhaust option which releases chamber pressure slowly and prevents boiling over of liquids. Cold air pockets are eliminated by continuous pressure purging which ensures uniform sterilization.
