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.

Applications
  • 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.
