The Davidson® Cryocup® System
Streamline the work of frozen tissue preparation.
The Davidson® Cryocup® System works with your existing equipment, such as microtomes and cryostats. Compatibility includes Leica, Microm (Avantik), Sakura, and Thermo-Shandon equipment.
Benefits
- Maintains cold temperature for quick freezing.
- Facilitates perfect flattening of oriented tissue specimens during freezing. Samples can be produced quickly, ready for slicing with little or no facing required.
- Quickly fills in if your cryostat loses temperature to help prevent work interruption.
- Portable, space-saving, and economical. Use in the field or in a satellite lab.
How to use the Cryocup® System
Following this process can achieve a perfectly flattened specimen, already faced, mounted on a chuck, and ready for slicing, in under a minute:
- Place dyed specimen into a Cryocup®.
- Fill with OCT up to the ledge.
- Place a Cryo Chuck (or one you already have) on top of the specimen.
- Place the Cryocup® in the Cryo Holder and lower the cover onto the Cryocup®.
- Dip the Cryocup® into liquid nitrogen (10 seconds).
- Drain. Remove Cryocup®.
- Warm Cryocup® slightly to release tissue specimen.
Ordering Information
Base your size choice on the size of chuck you may already have with your equipment, or the size of specimens you typically process.
NOTE: BPI indicates compatibility with most Leica, Sakura, and old style Thermo-Shandon equipment.

2. Stainless Steel Chucks
These stainless steel chucks are designed to be used cold for rapid freezing, and to maximize the gripping power required to hold the embedded tissue block. The stem of the chuck provides the focal point for a sharp tap resulting in an easily release of the block from the well. These chucks fit many of the major brand cryostat and can be used in most cryostats with use of an adapter. These Chuck Adapters have stem measures 20 mm L x 9 mm diameter, and fit Leica and most Microm cryostats. We also offer adapters to use these chuck for other cryostats.

3. Stainless Steel Over Chucks Freezing Blocks
Thee stainless steel rectangular blocks are a useful tool for a number of tasks. They serve as a heat extractor, designed to fit over the stem of the chuck. The flat surfaces can also be used as an extra heat extractor when using conventional cryostat embedding technique. The freezing block also served as a dislodging tool. A light tap of the chuck stem cleaves the plane of adhesion holding of the formed block to the well. These blocks also serve as a convenient hand held flat freezing surface useful in gently cooling the tissue without the use of sprays and in plastering technique.

5. Dispensing Slides
These thin transparent polyvinyl slides serve as a surface to precisely orient the tissue into the desired position and as a means to accurately transfer tissue to the embedding well floor. Tissue is applied face down to the end of the dispensing slide where it can be visualized from below and manipulated into position. The face that is visible will be laid onto the well floor and will ultimately be the embedded surface to be sectioned.

Freezing Griddle/ Elevated Freezing Block Set
Includes
Cutting board / Freezing griddle: The steel "freezing griddle" serves as a freezing surface on which to prepare frozen blocks when used in conjunction with the elevated freezing block. The small attached cutting board serves as a cold surface to cut the frozen block while maintaining the freezing temperature. This simple piece of apparatus is kept cold in the cryostat and is removed to the work bench only during the process of cutting the frozen block. As sections are cut, they are kept cold on the freezing griddle.
Elevated Freezing Block:This steel block is kept cold in the cryostat and in used in conjunction with the freezing griddle. The two broad sides of the block are equipped with feet measuring 3.0 mm on one side and 4.5 mm on the other. The feet create a space between the two steel bars in which the frozen blocks are prepared. Additional elevating bars are supplied to further elevate the block when preparing very thick portion of tissue.
