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 6875 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.
PLANETARY MIXERS
A flame polished glass connection!
Safe, tight and reliable connections are the crucial point for dependable operations of glass reactors in the chemical and pharmaceutical industry. The Buchi company founders recognized at an early stage that the flexibility of each individual glass joint is of huge importance. The unique buchiflex connection was invented as the basis of a complete modular glass system with interchangeable components.
Combined stirred filter reactor - one device for different reactions and process steps
The filter reactor (10-50 litres / optionally up to 250 litres) is a glass reactor with filtration capability that can be used for stirring, crystallising, homogenising, dissolving solids and separating solids. The glass apparatus with robust PFA-coated cover plate is located in a solid stainless steel frame.
