6875D Freezer/Mill® Dual Chamber Cryogenic Grinder
The 6875D Freezer/Mill® is a high-throughput, dual chamber, cryogenic grinder with a self-contained liquid nitrogen tub and insulated case. It chills samples in liquid nitrogen then pulverizes them with a magnetically driven impactor. It accommodates samples in the 0.1 gram to 200 gram range (100 per grinding chamber).
- Magnetically driven impactor is the only moving part so there are no mechanical linkages or bearings to fail.
- Auto-Fill System available for automated filling with liquid nitrogen.
- Liquid nitrogen required for operation. Equipped with liquid nitrogen level sensor, insulated case and lid safety interlock switch for operator protection.
- Grinding Vial Sets offered in a variety of materials including polycarbonate, stainless steel, and Cr-free steel. Sample vials maintain low level temperatures due to continuous immersion in liquid nitrogen.
- Dual cryogenic grinding chambers processes up to 200 grams of sample. Each grinding chamber can hold one large grinding vial, one mid-size vial, four standard grinding vials or four microvial sets.
- Easy use touch screen stores up to 20 user-defined grinding programs for easy quick recall. Also includes run history, training videos, manuals and accessories.
- Heat sensitive metabolites, isomers and complex molecules retain their composition as they are not degraded by heat or pressure.
- Safety features include LN sensor and lid interlock. Cryogenic grinding process stops if the lid is opened while the mill is running.
Cryogenic Grinding Applications include: DNA/RNA or protein extraction from tough tissue samples and yeast cultures,THC extraction, forensic testing, drug testing, RoHS/WEEE and volatiles extraction, contamination testing in pharmaceutical products and packaging following USP method 232.
Typical Samples: Plant and animal tissue, plastic and polymers, yeast, pharmaceuticals, food products, electronic components, textiles, hair & bones.
