The Tubing Cleaning Kit consists of two solutions for removing DAB precipitate from the reagent aspirating tubing (Z1 tubing) and residual wax from the waste tubing (z2 tubing) in the ONCORE Automated Slide Stainer. During routine staining, DAB residue may be left behind on tubing surfaces. Paraffin wax may also build up in the waste tubing. Regular use of the Tubing Cleaning Kit is recommended to remove DAB residue to ensure effective reagent extractions through the waste tubing. Each Tubing Cleaning Kit is good for 3 cleaning cycles. Please refer to the ONCORE Automated Slide Staining System User Manual for the recommended cleaning schedule.
