Does anyone have a problem with mold growth in diluent 2 that is being rotated on and off  the Vision analyzer.  We are currently loading a Diluent 2 and Diluent 2+ set each morning and rotating the set back to the refrigerator after 24 hours on board.  Due to low usage after 3 weeks we have mold growth

We use MTS 2 plus routinely. We keep ours on board only 16 hrs (two shifts) then midnight has their own set.

We rarely use MTS 2 ---After performing daily QC we store our MTS 2 in Ref. until we need to use it for patient or until next day for QC.

We rotate ours out every morning and are able to use the entire bottle without a mold problem. I would wonder if the refrigerator isn't harboring it somewhere and that's the problem, not the diluent itself.
