5.1 Cleaning
W
ARNING
Always switch off the VACUSAFE and disconnect it from the mains when
carrying out maintenance work.
Clean the VACUSAFE housing with a lint-free cloth lightly soaked with mild soap solution
in distilled water or with a 70% solution of isopropanol or ethanol. Never use bleach
(sodium hypochlorite) or other solvents.
It is recommended to change the hydrophobic filter regularly, at least once a year.
Exchange the filter immediately if liquid has entered.
When working with solvents and other hazardous materials always rinse the hand
operator and tubing with water followed by 70% ethanol.
5.2 Autoclaving and chemical sterilization
5.2.1 Autoclaving
All parts contacting the liquid can be autoclaved: waste collection bottle, lid with tube
fittings, silicone tubing and hand operator VACUBOY. When working with biohazardous
material, disinfect the VACUBOY with a 70% solution of isopropanol or ethanol or a
suitable disinfectant before disassembling for autoclaving. For disassembly please refer
to the operating instructions VACUBOY. Recommendation regarding autoclaving:
polypropylene bottle for at least 60 min, glass bottle and disassembled VACUBOY for at
least 20 min at 121°C.
The bottle lid has to be always unscrewed and kept loosely on the bottle during
autoclaving. The tubing couplings made of PVDF have to be always disconnected during
autoclaving.
Silicone may become brittle after extensive autoclaving. Replace the tubings if they are
damaged.

ARNING
It is not recommended to autoclave the VACUBOY regularly as premature
material aging may occur.
The filter and the instrument itself cannot be autoclaved.
5.2.2 Chemical sterilization
Two methods for chemical inactivation of biohazardous agents are commonly used:
• A suitable disinfectant is added to the full collection bottle and left to react for the recom-
mended time. Any disinfectant can be used, provided that it is compatible with the bottle
material (glass or polypropylene).
• The disinfectant is added to the empty bottle so that the aspirated liquid gets sterilized
as it accumulates in the bottle. Use disinfectants that are free of chlorine or other corro-
sive agents, especially when corrosive vapors are generated and aspirated.
