What to look for in a steriliser

What to look into a steriliser Banner

Image of the W&H Lisa VAIt’s essential to have sound instrument handling procedures and a proven and traceable sterilization protocol – especially in busy dental practices – to ensure staff and patients are protected from potential infections from dental instruments.

Recognising this, the new W&H Lisa VA sets a new benchmark in fast, simple and secure sterilization – ensuring infection control standards are more consistently maintained in the dental practice.

The need for speed

The Lisa VA employs advanced, patented Eco Dry technology that adapts the drying time to the mass of the load – the smaller the load, the less drying time needed – without compromising necessary cycle parameters for time, steam and temperature!

The Eco Dry process enables the Lisa VA to process and completely dry a typical 2kg B-type mixed load in just 30 minutes. Lisa also offers the option of an extremely quick 13-minute cycle for small loads of unwrapped instruments. Reducing cycle time eliminates unnecessary exposure to heat, which extends the life of instruments and reduces energy consumption.

Easy to use

Thanks to its new colour touch screen and intuitive menu structure, the LISA VA-series is extremely simple to use. The display can be easily customised to commence a fully automatic B Cycle at the single touch of a button, ensuring all load types (solid, hollow, porous, wrapped or unwrapped) are properly sterilized. This is important, because selecting the B Cycle ensures adequate air removal and steam penetration for porous and hollow wrapped loads.

Password protection – App control

The Lisa can be connected to computer via Ethernet, or the data downloaded at any time on an 8GB USB device. Or with the convenient free Lisa Mobile App, the operator can monitor up to four sterilizers wirelessly on a Smartphone or tablet in real time from anywhere in the practice.

The Lisa Mobile App is able to retrieve cycle reports from the barcode printed by the optional LisaSafe label printer. The barcode can be read with a Smartphone camera.

The printed label’s bar code information can be scanned directly into a patient file linking a sterilization cycle with a single patient, clinician and procedure – i.e. batch control identification – providing a permanent record for medico legal purposes

Air detector

To be effective, a vacuum steam sterilizer must remove all air from within the load (pre-vacuum phase) before the sterilizing phase commences. The Lisa VA is the only bench-top sterilizer with a built-in air detector that confirms instruments are exposed to saturated steam without the presence of air pockets in every cycle, thereby negating the option to use a batch load PCD (process challenge device).
