Water Quality
Physical characteristics and contaminants levels
The distilled or mineral – free water supplied to the autoclave should
have the physical characteristics and maximum acceptable level of
contaminants indicated in the table below:
Physical Characteristics and Maximum acceptable contaminants
levels in water for sterlizers
(According to ANSI/AAMI ST79:2006).
Element
Condensate – allowable content
Evaporate residue
≤
15 miligrams/liter (mg/l)
Silica
≤
2 mg/l
Iron
≤
0.2 mg/l
Cadmium
≤
0.005 mg/l
Lead
≤
0.05 mg/l
Rest of heavy metals
≤
0.1 mg/l
Chloride
≤
3 mg/l
Phosphate
≤
0.5 mg/l
Conductivity
≤
50
μ
s/cm
pH value
6.5 to 8
Appearance
Colorless, clean, without sediment
Hardness
≤
0.1 mmol/l
Compliance with the above data should be tested in accordance
with acknowledged analytical methods, by an authorized
laboratory.
Attention:
We recommend testing the water quality once a month. The use of
water for autoclaves that does not comply with the table above may
have severe impact on the working life of the sterilizer and can
invalidate the manufacturer’s guarantee.
