The Wincom DH4000BII (DH4000B II) Laboratory Thermostat Incubator is a desktop, electric constant-temperature device designed primarily for medical laboratories, food processing, agriculture, biochemistry, and industrial applications to culture bacteria and microorganisms. The “B” designation specifies that the inner chamber is constructed from high-quality stainless steel (as opposed to standard galvanized metal templates), which increases its corrosion resistance and makes it much easier to clean.
