HI,
  Can anyone tell me if you've ever seen a jaw type chuck holder (or adapter) for a cm1850 leica cryostat. I am getting in some frozen tissue that has been embedded in square embedding rings. I have an adapter for for square blocks, but the clamp only consist of a screw holding the block in place. It simply is not stable enough to hold my embedding ring. Any suggestions?
                                              Thanks,
                                               Sirena HT (ascp)
