SilcoTek ® SursanBiological passivation treatment process for stainless steel

Ensure the biological passivation performance of the stainless steel inner surface in biochemical experiments and analysis systems

In analytical instruments and experimental devices, it is often required that the surface of the flow path system has biological inertness to ensure the accuracy of experimental or analytical results. Due to frequent flushing and erosion, some chemically active substances corrode the pipeline and form some potholes, which can cause the retention of viscous substances such as proteins in the sample.

Generally, the surface of stainless steel has activity, which allows proteins to form internal residues. Surface treatment is necessary in medical equipment and biochemical analysis instrumentsReason. The method is to use fluoropolymer (PEEK AF1600) material for coating.

However, using this material to change the surface properties of the pipeline has its limitations, manifested as not being durable for a long time. This method still has problems that cannot be solved for some common complex compounds in medical devices.

DursanworkArt is a three-dimensional chemical vapor deposition surface treatment method that can be easily passivated in complex shapes and crevices. Its main characteristics are:

Good biological inertness

The expensive cost of surface treatment with good biological inertness，We need to consider

lImprove analytical sensitivity and eliminate the interaction between samples and inner surface metals

lCoatings should be non-toxic, have good inertness, and not pollute the environment

lWhen analyzing multiple proteins, prevent the formation of additional positive results from other proteins

Surface anti-corrosion

lThe protective layer can prevent the formation of spots, and there will be no retention or protein migration

lImprove the corrosion resistance of stainless steel. The commonly used bleaching and rinsing agents can also corrode stainless steel. The coating processed in this way can be made of Baohu stainless steel and is very durable，SilcoTektronix ® DursanThe chemical vapor deposition surface treatment process can be applied in15%NaCIOChinese72No corrosion occurs within hours

pollution prevention

lThe coating will not stick and will not retain proteins, blood, or biomolecules on the surface of the coating

lA non stick coating surface can improve analytical sensitivity and reliability, increase the continuous operation time of the instrument, and improve work efficiency

linertCVDThe (chemical vapor deposition) coating can prevent sticking and is very easy to clean with non-ionic activators

DursanSurface treatment processes can reduce protein adsorption and promote its movement

Handle without leaving any blind spots

It is possible to passivate the hard to reach dead corners in the system

lThe gaps between complex parts and the inner and outer surfaces of the needle can be passivated. Therefore, it can improve the inertia of the entire complex system and provide protection

lThis passivation treatment process is very precise and will not change the dimensions and tolerances of the processed parts and systems. Directly process the original design system without the need for redesign

Reliable coating

lThe coating surface is sturdy and reliable, will not peel off, and can even undergo bending and other process treatments.
