This Miele washer-disinfector is

capable of cleaning a wide range of

medical and laboratory products, and

disinfecting them either thermally in

temperatures up to 95 °C or chemo-

thermally in temperatures up to 65 °C

with the addition of a suitable chemical

agent in accordance with general

standards of hygiene and those

required for the containing of

epidemics.

Medical products include e. g. surgical

and minimally invasive instruments,

instruments and utensils used in

anaesthetics and intensive care, etc.

Laboratory products include e.g. wide

and narrow necked flasks, conical

flasks, measuring cylinders, pipettes,

beakers, Petri dishes etc.

Follow medical and laboratory product

manufacturer’s instructions on how to

process their items by machine. The

DESIN vario TD programme provides

optimum protection for rigid fibre

optics, patient systems and surgical

motor systems which have been

declared by their manufacturers as

being suitable for machine processing.

Optional drying with sterile filtered hot

air is also available.

Areas of application:

–surgical instruments,

–minimally invasive instruments can

be processed shortly after use,

–anaesthetic and intensive care

instruments,

–baby bottles and teats,

–stainless steel and aluminium

containers (including anodised

aluminium),

–operating theatre shoes,

– laboratory products used in research

and production as well as in all areas

of analysis and specimen taking,

including micro-biology and

biotechnology.

Instruments should preferably be

cleaned and then thermally disinfected

using the DESIN vario TD programme.

The parameters for thermal disinfection

in accordance with prEN ISO 15883-1

are 80 °C (+ 5 °C, - 0 °C) with a 10 min.

holding time or 90 °C (+ 5 °C, - 0 °C)

with a 5 min. holding time for the

inactivation of HBV.

Description of the machine

In the U.K. reference should be made

to your local infection control officer for

guidelines of disinfection temperatures

and holding times at temperature in

accordance with HTM 2030.

In Germany, the parameters for

disinfection of a temperature of 93 °C,

with a holding time of 10 minutes,

correspond to effective areas A and B.

These have been adopted into the

official list for disinfection of instruments

in washer-disinfectors and

decontamination units, according to

section 3.2 § 18 IfSG by the Robert

Koch Institute (RKI) in Berlin (institute

for infectious diseases and non-

communicable illnesses). (Programme

DESIN-BSG-93/10).

The effective areas are defined as

follows:

A = Suitable for the destruction of

vegetative bacteria, including

myco-bacteria, fungi and fungal

spores.

B = Suitable for inactivating viruses

(including HBV and HIV).

The cleaning programme must be

chosen according to the type of soiling

and product requiring processing in

order to ensure that disinfection is

carried out correctly, no residues are

left behind and that subsequent

sterilisation can take place. Medical

devices are best reprocessed using the

DESIN vario TD programme, or the

OXIVARIO programme where

applicable.

This washer-disinfector is programmed

to carry out the final rinse with mains

water or AD water (aqua destillata =

purified or de-ionised water (VE), H2O

pure, demineralised water or distilled

water where the application requires

this standard).

The water quality is of particular

importance for applications requiring

analytically clean laboratory glassware.

The type of chemical agents used will

depend on the analysis or analytical

methods being used.

Optional extras

– Drying unit (TA)

– Steam condenser (DK)

– Report printer (PRT)

– Dispensing systems DOS 2 and

DOS 4

– OXIVARIO kit

Water softener

If the mains water hardness level is

more than 70 mg/l (4°d), a water

softening system should be provided

on site, such as the Miele G 7897

"Aqua-Soft system" which is effective up

to approx 720 mg/l (40°d).
