The cleaning and decontamination concentrate solutions sold by BD are very expensive, considering that we still have to buy the replacement kit with filters, inline filter, and rubber tubbings. I figured that the cleaning solution could be made of 0.2 microns filtered neutral extran, but the final dilution should be important. Also, the decontamination could be filtered bleach, but again the right concentration is important. Our experience with the Accuri C6 has shown that it is not very robust so I prefer not to test directly if someone can offer some advise.
As for the replacement kit, the entrance filters and probably inline filters can be bought from other sellers, as those are standards (but what is the mesh of the inline filter? also 0.2 microns?). But I think there is no alternative for the rubber tubbings of the peristaltic pump.
Best,
