Although they do not usually represent a risk from a hygiene perspective, inorganic residue can cause problems for the instruments' functionality. If it is detected too late, in the worst-case scenario an operation can be abandoned or delayed due to non-functioning instruments - and this is associated with enormous costs for the health facility!
So why take that risk if thorough cleaning, protection and value retention can all be achieved with deconex® 34 GR?
Thanks to its formulation, deconex® 34 GR can be used for thorough cleaning and passivation using both manual and automated methods. This powerful product is also easy to use: surgical instruments are made like new in just two steps.
The special formulation, involving a combination of phosphoric and nitric acid, can be used for both manual (including in an ultrasound bath, for example) or mechanical cleaning in the WD. With both options, a suitable process removes inorganic deposits and stains, the instrument shines like new again and its functionality is restored.
The acidic thorough cleaning removes the passivation layer that has already built up, revealing the new instruments "original state". In a second step, the task is to build up a new passivation layer to ensure that the instrument retains its value.
Regenerating the passivation layer generally involves various methods and numerous steps and takes a long time. With deconex® 34 GR, passivation can be achieved with just one end-to-end automated process and the results are of the highest quality.
A study recently carried out by Borer Chemie AG in conjunction with the Empa (Eidgenössische Materialprüfungs- und Forschungsanstalt) impressively demonstrates that, while the usual citric acid-based passivation methods form a passivation layer of around 2 nm, a passivation layer five times thicker (10 nm) was formed with deconex® 34 GR.
The 2-stage process with deconex® 34 GR therefore not only removes inorganic residue from your stainless steel instruments, but also - thanks to the subsequent passivation step - also ensures that they retain their value.
