21 Sterilisers
21.1 Purpose definition for MEMMERT hot air sterilisers
The oven SFP is intended for the sterilisation of medical materials by dry heat using hot air at atmospheric
pressure.
21.2 Notes in accordance with Medical Products Guidelines
For sterilisers in the context of the Law on Medical Products (MPG), the „Celsius“ software may only be
used for logging purposes, but not for the remote control (remote operation) of devices.
The product lifetime specified by the manufacturer is 8 years.
21.3 Guidelines for sterilisation in MEMMERT hot air sterilisers
For hot air sterilisation there are different regulations covering the temperature settings and the sterilisation
times, as well as the packaging of the products to be sterilised. The values to be selected depend on the
type and condition of the load to be sterilised and on the type of bacteria which have to be de-activated.
Please make yourself familiar with the sterilisation method laid down for your application before carrying
out sterilisation using your MEMMERT cabinet.
The operation of the MEMMERT hot air steriliser is also subject to the Standard DIN 58 947 Part 6.
A few examples of the correct preparation for different medical products are summarised in the following
table:
Load Preparation
Instruments (no soft solder) load cleaned instruments, wrapped twice in aluminium foil or in
steriliser foil suitable for hot air (recommended)
Cutting instruments load cleaned instruments, wrapped twice in aluminium foil or in
steriliser foil suitable for hot air (recommended)
Syringes (no plastics) load plunger and cylinder separately, wrapped twice in aluminium
foil or in steriliser foil suitable for hot air (recommended)
Glass and glass instruments dismantle cleaned glass vessels and all-glass syringes and place into
dishes, cool down slowly
FBottles, vessels and similar items must be sterilised without closure and with the opening downwards,
in order to avoid the formation of cold air pockets. The recommended sterilisation temperature is usually
180°C (German Pharmacopoeia DAB 10).
Sterlisation should in all cases be carried out as setpoint-dependent operation, according to the following
example. The holding time to be selected consists of the stabilisation time (i.e. the time until the desired
temperature has been established within the entire steriliser chamber), the actual sterilisation time, and a
safety margin.
