Choosing the Proper Angle for your Sectioning Needs

The patented Cryogun is a cost-effective, innovative product that allows you to work in-situ for the most accurate sample collection possible.



Innovative - When structural and biochemical integrity is a must, the Patented Cryogun will assure you of the best-frozen and/or vitrified samples achievable today.

Flexible - Freeze samples for cryotomy, cryoultramicrotomy, freeze drying or freeze substitution. One instrument with our simple protocols increases productivity and reduces training costs.

Portable - Take cryofixation into the animal, into the operating room, even into the field. Work in-situ for the most natural, most accurate sample collection possible.

  • In-vitro and in-vivo sample collection
  • Slam and plunge freezing
  • Lab, field and surgical applications
  • Routine histology and electron microscopy
  • Immunohistochemistry and immunocytochemistry
  • Analytical x-ray microanalysis

Cryogun Specifications - Portable slammer with air-actuated cylinder operated with a hand trigger. Handle is made of Delrin™, a durable insulating plastic. Other parts made of stainless steel for rust-resistance, rapid cooling and insulation of air cylinder. The steel specimen holder is mechanically held to the piston of a pneumatic cylinder. Special foam, foil and cover slip materials are assembled to properly hold, align, and protect the specimen during slamming. Ten feet of Tygon™ tubing for connection to ¼" hose barb at your air pressure regulator set for 60 - 100 psi.


Cryogun Consumables Kit - Includes four specimen holders, tools and supplies for making foam, aluminum and plastic discs and 216 sticky tabs. Pair of tweezers for handling specimen holders

Styrofoam Workstation- Styrofoam workstation for precooling the Cryogun and storing frozen samples with liquid nitrogen.

Anvils - Two, high-purity copper anvils with 8 mm diameter contact surface.

Freeze Substitution Heat Sink and Workstation - Aluminum block with high thermal mass and space for 18 sample vials. Supplied with eight vials.

Freeze Drying Workstation - Copper block set-up for large or small specimens, includes a porous cover.

On-site Training Using the Cryogun Hand-Held Metal Mirror Cryofixation Device - A DDK expert in cryo-fixation will come to your site and provide hands-on training in use of the Cryogun. We'll show you how the Cryogun can increase productivity while allowing for the most accurate sample collection possible. DDK's Cryogun on-site training costs $1,000 per day plus travel expenses.
