The document discusses the W&H Lisa VA sterilizer and its features for dental practices. It has advanced drying technology that reduces drying times without compromising safety. A typical load can be processed and dried in just 30 minutes. It also has an easy-to-use touchscreen, password protection, and connectivity features. The sterilizer ensures effective air removal and steam exposure in every cycle thanks to its built-in air detector.

t’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 EcoDry 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 com-
pletely 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 auto-
matic B Cycle at the single touch of a button, ensuring all load
types (solid, hollow, porous, wrapped or unwrapped) are prop-
erly 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 (pro-
cess challenge device).
