What to look for in a steriliser

What to look for in a steriliser

It’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

In keeping with Australian Standards AS 4815 and AS 4187 for traceability requirements, Lisa offers the option of password protected user identification at load release and automatic capture of cycle data.

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).

New W&H Lisa: Fast, easy sterilisation!

New W&H Lisa: Fast, easy sterilisation!

The efficient new  W&H Lisa sterilizer  features major performance, user interface and traceability options, building on the groundbreaking innovations of earlier W&H  Lisa sterilizers. New features include an accelerated “Type B” sterilization cycle for quicker processing of the average load, an  intuitive colour touchpad and Real Time Remote Monitoring via WiFi.

Performance Patented advanced Eco Dry technology adapts the drying time to the mass of the load. The W&H Lisa is the only bench-top steam sterilizer with an air detector which tests for the presence of air pockets to ensure the load has appropriate exposure to saturated steam. Automatic adjustment of the drying time depending on the load reduces the heat exposure time. This extends the service life of the instruments and means less energy consumption. Lisa offers a fast Class B cycle to  process and completely dry 2 kg of typical load in only 30 minutes. Lisa also offers the option of an extremely quick “S-cycle” for the sterilization of unwrapped instruments – which can be removed from the sterilizer ready for use after just 13 minutes!

Easy to use The new Lisa colour touch screen with its user-friendly menu structure and intuitive menus has been selected and designed to make daily work easier, faster and more efficient with the  following features:

  • Simple cycle selection – The home screen displays the cycle selection on power-up;
  • Intuitive navigation – The Lisa touch screen displays four logical groups  of activities for swift and efficient  navigation; and
  • User guidance – 3D animations show maintenance operations step-by-step.

Traceability Cycle details can be automatically saved on the integrated 8 gigabyte USB drive, without the need for additional cables or external equipment such as a PC. Or, with the convenient free Lisa Mobile App, the operator can monitor up to 4 sterilizers on a Smartphone or tablet in real time from any place in the practice. The Lisa Mobile App is able to retrieve cycle reports from a barcode label printed by LisaSafe. The barcode can be read with the Smartphone camera.

Ergonomics The revised internal and external Lisa design features an integrated funnel preventing water splashes during the water filling process. An automatic water-filling valve allows connection to a  demineralization system. Thanks to the optimized internal air circulation, the sterilizer can be built into a cabinet as well. The compact design enables the new Lisa to be easily and seamlessly integrated into spaces with as little as 45 cm shelf depth.

Cleaning and maintenance The smooth surface design with minimal gaps makes cleaning easier. A built in help function with animations provides step-by-step guidance for routine maintenance procedures.

Model options The new Lisa is available in two chamber sizes: 17 litres and 22 litres and is supplied with a reversible rack,  5 aluminium trays, drain tube, tray holder, 8 GB USB drive, door opening tool and factory test information.
