USEFUL ADVICE AND SUGGESTIONS

The type of detergent to be used. In order to wash any instrument or object, use tap water as the main substance
and dissolve in it a quantity of detergent or solution which varies according to the type of material residue to be removed
from the object. Only use pure detergent if expressly specified in the instructions for use of the product. If for example
an object soiled with greasy or fatty material is to be cleaned, use a small quantity of SONICA
water as indicated in the instructions for the product and clean in ultrasounds.
®
The SONICA UG detergent enables removal of many types of impurities.
When small quantities of plaster have to be removed. Use pure SONICA
directly into the tank. Its strong action will allow total removal of the plaster even from dental prostheses.
When many objects have to be cleaned. Do not overload the ultrasonic cleaning unit. Preferably arrange the objects
rationally on the base of the rectangular basket, place the latter in the tank and clean as appropriate. Too many objects
washed at the same time reduce the efficiency of cleaning with ultrasounds.
When the objects are very dirty. Use long cleaning times, heating the washing liquid according to the object to be washed.
When to replace the detergent solution. To achieve efficient cleaning change the detergent solution often, above all
if it is used to clean surgical instruments.
Shape and size. There are no special rules for the shape of objects to be cleaned, however avoid inserting particularly
heavy and large objects in the tank.
The liquid must always cover the entire object.
Cleaning time. The cleaning time always depends on the type of object, and the type and quantity of the material to be
removed.

culator plates, spatulas, miscellaneous instruments, all types of prostheses. Can also be used for gypsum investments
When plaster comes into contact with the cleaning liquid small bubbles form and show that the detergent is acting on
the plaster. The product should not be diluted. pH 7.5-8.5
®
SONICA CL 4% is a concentrated aqueous solution with decontaminating and cleansing action developed for using
®
with SONICA Ultrasonic cleaners. The solution is concentrated.
Application Fields
Decontamination and simultaneous detergency of surgical instruments and medical devices. Temporary ste-
rile conservation of surgical instruments.
Action Mechanism
Chlorexidine reacts with the negatively charged groups that are found on the cell surface. For this reason,
when it comes into contact with bacterial suspensions, it is absorbed immediately, causing an irreversible
loss of cytoplasm components, which damages the cell membrane and inhibits enzymes. Cetrimide is a qua-
ternary ammonium salt that reduces surface tension in the point of contact and has precipitant, complexing
and denaturing effects on bacteria proteins, causing enzyme changes in the cytoplasm membrane.
Germicidal Activity
Chlorexidine acts on vegetative bacteria, yeasts, fungi, several protozoa, viruses (HIV) and salmonella. Cetrimide acts as
a bactericide above all on gram-positive bacteria; it has varying fungistat properties and acts as a virucide against lipophi-
lic viruses. The action of the product is superior to that of its single components. Its bactericidal actions are reduced by
the presence of organic material (serum).
