The Hirayama HV series of 50, 85 and 110 liter autoclave sterilizers are portable, self-contained, top-loading sterilizers with auto exhaust and a warming cycle. This top-loading autoclave has a lid that rises, which is a space saver.The HV series has a dual-sensing lid interlock feature that shut prevents the lid from opening when the chamber is pressurized or when the temperature exceeds 200°F. 

The Hirayama HV series had a agar melting mode and can maintain agar at a liquid temperature which provides for a hotter, quicker start. 

The Hirayama HV sterilizer autoclaves features a one-touch lever to make it easier to open and close the chamber lid. The In-Process indicator provides the status and progress of sterilization cycles. 

The sterilization cycle will not start unless the autoclave's door has closed correctly.
