Compact Benchtop Labmill runs smoothly and quietly, adjusting easily for four sizes of milling jars from 0.5—10L (16—320oz). Sample volumes from 75ml to 4L can be handled with unattended ease. Estimated specimen capacity of jars is approximately 25% of total jar volume. Volume for grinding media required is approximately 50% of jar volume. The special HDPE (High Density Polethylene) jars are disposable to avoid cross-contamination and feature baffled interiors for efficient wet or dry grinding action. Each milling jar is held in a supporting metal sleeve for rigidity. Sleeves for 0.5 and 1L jars are stainless steel; larger sleeves are anodized aluminum.
The unit also holds other grinding jars, from 3—7in (75—178mm) diameter, and up to 11in (279mm) width. A speed control switch gives 10—260rpm roller speed from the direct-drive 60 Watt DC motor. For 230V, 50/60Hz electrical supplies, order TR-502 Transformer separately. Disposable Grinding Jars and Supporting Metal Sleeves are ordered separately.
