Cryostat Tissue-Tek’s Cryo3 Sakura

Location: CC-2301 MCN

Reservations required in  VU iLab website


The Sakura Cryostat has a unique rake which can be used instead of a glass anti-roll plate. This rake performs perfectly when the specimens are mounted in a certain way. Training is free and is suggested to ensure that your specimens get mounted correctly and you are able to use the rake effectively. Although the idea of learning a new way to cryosection would be a “no go” in some people’s minds, the individuals who have embraced this new method actually get better and more consistent sections. No longer do you have to contend with wasted sections folding under the glass.

If you want to use a glass anti-roll plate, you are required to purchase one of these from the company. It is a “non-file” item number 0000707-06. Do not let them sell you the more expensive anti-roll plate which contains the metal arm which holds the glass. It is not necessary.

The CDB Equipment Core retains five 25 mm and five 38 mm round specimen holders. These can be signed out from the U3202 equipment room for use. However, the holders must be cleaned and returned to the equipment room after you finish sectioning. If your lab would like the convenience of having your own holders, ordering information is below.
