It has nothing to do with your coverslipper. Ours is from the mid 90's
and we have had the brown spots a couple of times. We found that there
to be water in our xylene. The little water droplets on the side of a
container will cause this. Make sure everything that holds xylene is
completely dry. Once we did this, we had no more brown spots. Good luck!
As far as xylene residue, it is your dispensing volume on the
coverslipper that is causing this. Try turning the flow down and see
what happens.

Quoting Jackie M O'Connor <Jackie.O'con...@abbott.com>:
I have an older Sakura coverslipper, circa 1997ish. We have noticed an
increasing number of brown spots on tissue sections recently. This does
not occur if the same slides are covered with glass coverslips. It does
not look like a drying artefact, occurs randomly throughout tissue types,
location on tissue, i.e., edge, center. I've even showed these spots to
the rep who admitted she has never seen this artefact before. We use
only the Tissue Tek tape, we maintain the equipment on a regular basis.
The xylene flow is good. Our only problem are these random brown spots.
Any suggestions?

RE: [Histonet] Sakura film coverslipper xylene residue issue
Hi Scott,
We place ours in front of a fan to dry if we are in a hurry, even if
we air dry them we do not have a problem with the xylene residue,
perhaps you have a bad batch, check your lot # and call Sakura. We
coverslip over 1,000 slides a day and have not seen this.

Subject: [Histonet] Sakura film coverslipper xylene residue issue
Hi,
We have a newer Sakura film coverslipper, does anyone have
experience with this piece of equipment. I have a problem with the
slides having a light xylene residue, after the slides come off of the
coverslipper.
How do you dry them? If I leave the slides on the coverslipper to air
dry the xylene residue is noticeable. If I lightly wipe off all of the
slides as they come off the coverslipper they look clean.
How do you guys do it? I think it is a waste of time to wipe off all of
the slides. I don't think the xylene flow is too high.
Thanks for your help,
Scott Hendricksen HT(ASCP)
