Retsch® Jaw Crusher BB 50 with Manganese Steel Breaking Jaws & Stainless Steel Wearing Plates, 200-240 V 50/60 Hz, 20.062.0001Designed specifically for laboratory sample preparation, this jaw crusher is used for rapid, effective crushing and pre-crushing of medium-hard, brittle and tough materials. This instrument has a space-saving footprint, dust-tight casing and is ideally suited to crush small amounts of sample with large feed sizes gently and without loss. Other breaking jaws and wearing plates materials are available to meet your needs, even a unit with ceramic materials to avoid metallic contamination. Reproducible results can be obtained using the BB 50 due to digital gap width display and zero point adjustment.
