CRYOGENIC GRINDERS
The Cole-Parmer CG-200 Freezer / Mill® cryogenic grinder (formerly SPEX 6775 Freezer/Mill) - for sample quantities from 0.1 to 5 g. The first choice for grinding very small quantities of temperature-sensitive samples or for samples that are impossible to grind at room temperature.
The entry-level model for cryogenic sample grinding, ideal for small and very small sample quantities. The sample jar is PERMANENTLY immersed in liquid nitrogen to embrittle the samples. Permanent cooling, robust mechanics and intuitive touch screen operation for maximum efficiency and durability.
The Cole-Parmer CG-400 Freezer/Mill® Cryogenic Grinder (formerly SPEX 6785 Freezer/Mill) - the first choice for grinding sample quantities from 0.1 to 100g for temperature sensitive samples or samples that cannot be ground at room temperature.
The basic model in the Cole-Parmer Freezer/Mill range requires manual filling with liquid nitrogen. Continuous cooling of the sample container in liquid nitrogen, robust mechanics with only one moving part and intuitive touch screen operation ensure maximum efficiency and durability.
The Cole-Parmer CG-450 Freezer/Mill® cryogenic grinder (formerly SPEX 6785 Freezer/Mill) – including the Auto-Fill – function. The first choice for grinding sample quantities between 0.1 and 100g in the case of temperature-sensitive samples or samples that are impossible to grind at room temperature.
The sister model of the CG-400 is filled with liquid nitrogen automatically. The permanent cooling of the sample container in liquid nitrogen, the robust mechanics with only one moving part and the intuitive touchscreen operation ensure maximum efficiency and durability.
The CG-500 Freezer/Mill® is a high-throughput, dual chamber, cryogenic grinder. It accommodates samples in the 0.1 to 200g range (100g per grinding chamber). Each grinding chamber can hold one large grinding vial or four standard grinding vials. Sample vial maintains cryogenic temperatures due to continuous immersion in liquid nitrogen.
When performance matters: The top model from the Freezer/Mill series offers two grinding chambers, two pre-cooling chambers and the choice of manual or automatic filling with liquid nitrogen. The permanent cooling, the robust mechanics and the intuitive touchscreen operation ensure maximum efficiency and durability.
