I'm looking for a durable matrix slicer to make coronal slicers of an adult rat heart in increments of 1 mm. I'm looking currently at Zivic Instruments and Cell Point Scientific, but am not sure if they are reliable.
An update for those interested -- slicer matrices can be 3D printed using a MakerBot2 and the template available through the NIH 3D printing catalog. I did this myself and it works great!
I have brain slicers from Zivic, but I will warn you that it took over 9 months for them to ship to me (despite MANY phone calls and emails and frustration) and one of them wasn't in good condition when it arrived. I would try Cell Point if you've heard good things about them.
Do you have a link to the slicer you found on NIH 3D printing. I seem only to be able to find one for brains? Or did you just customise that one for your own needs?
