The Chamber Cleaning Kit consists of three solutions intended for cleaning the tubing and chamber surfaces that come in contact with 3,3’-diaminobenzidine (DAB) in the ONCORE Automated Slide Stainer. During routine staining, DAB residue may be left behind on these surfaces. Regular use of the Chamber Cleaning Kit is recommended to remove DAB residue and prevent a hue on slides. Each Chamber Cleaning Kit is good for 8 cleaning cycles. Please refer to the ONCORE Automated Slide Staining System User Manual for recommended cleaning schedule.
