Hand-held metal mirror cryofixation devise
Simplify freezing your samples while achieving more accurate results.The patented Cryogun is a cost-effective, innovative product that allows you to work in-situ for the most accurate sample collection possible.
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.
