SPEX CertiPrep™ Large Freezer Mill

Description

Fully programmable freezer mill that can store up to 10 user-defined methods for simple, fast and error free recall. A full color, detachable control screen is intuitive to use for quick and easy set-up and operation. A truly cryogenic mill that cools samples in liquid nitrogen and then pulverises them by magnetically shuttling a steel impactor between two steel end plugs within a sealed vial. The dual chamber allows for high throughput applications. Suitable for samples up to 200 grams (100 grams per chamber). This mill is supplied with a choice of one included accessory pack: if using large vials only, specify pack 6870L; if running small vials specify 6870S; if using midsize vials select, 6870M. If running more than one size of vial, more than one of these accessory packs will be needed, so order them as required.
