RE: [Histonet] pens

Xylene also works the same way, with the pens soaking in for an hour or so. Or you can take the back off the pen and add 3-4 drops of xylene, store the pen tip down for a couple of minutes to let it soak through, and it works again.

You can try to "refresh" dried pens by pouring a very thin level of
acetone in a beaker and placing the pens, tip down, into the beaker.
Cover and leave overnight.  The level of the acetone should be no higher
than the pen tips.
Sometimes it works, sometimes not. Good luck!

We recently had the same problems and researched several companies and
brands and found for our usage the following were the best: 

Surgipath pens #01880 come in a box of 10 for $27.00

Marketlab pens #ML0479 come in a box of 10 for $37.00

Mercedes Medical has a new pen from Norway that we tried that are only
$13 per box of 10, but do not have the order number for them as they are
not in stock quite yet.

The pens from Newcomer (Histo pen) and the Cancer Diagnostics pen did
not smear, etc., but dried out so fast and often came already dry in the

Good Luck!!
