Dual Vial Grinding Mill

Dual Vial Grinding Mill

Dual Vial Grinding Mill
The Dual Vial Grinding Mill is a development in reply to requests offered by the biological, medical, agricultural and forensic communities to provide for greater productivity, sampling efficiency and extended grinding duration. Two designs are available and each can grind, mix or homogenize two (2) sample vials simultaneously. The Model 200 accommodates a selection of vials providing for sample volume from 0.2ml - 10ml while Model 400 supports sample capacities up to 20ml. In one single operation, the Model 400 can process up to twenty (20) samples for DNA and RNA biological cell disruption using adapter racks which hold 5 or 10 disposable reaction vials. The mills are particularly useful for wet grinding using stainless steel screw top, PTFE sealed vials. CLICK HERE to watch a short video showing how easy it is to use the Dual Vial Grinding Mill.

The mills include digital keypad entry, 10 seconds - 99 minute timer, safety cover and variable speed programming (3 - 30 vibrations per second). The electronics also feature a memory function for programming three (3) different grinding settings to guarantee reproducibility.

A variety of vials and ball pestles has expanded the flexible use of these mills which can produce 5 micron particle size depending upon the sample. Vial and ball pestle materials include agate, sintered alumina, zirconium oxide, stainless steel, chrome steel, tungsten carbide, teflon and polystyrene/polyamide. Choose from a range of vial sizes (1.50ml, 5ml, 10ml, 25ml, 35ml and 50ml) and ball pestle diameters (5mm, 7mm, 10mm, 12mm and 20mm). Reaction vials provide for volume capacity of 0.20ml, 0.50ml, 1.5ml and 2.0ml. Ball pestle diameters for reaction vials include 3mm, 4mm, 5mm tungsten carbide and 5mm stainless steel. Consult with REFLEX Analytical to suggest a suitable vial and pestle combination.

The Model 400 Mill can also be used as a Cryogenic Grinding Mill. The sample and pestle are safely contained in a screw capped, stainless steel vial which is immersed in liquid nitrogen and then placed into the Mill's self-locking clamps. After an agitation time of only 1 - 3 minutes, a truly homogeneous sample is produced. Contrary to other methods, there is no pre-cooling or intermediate cooling time required, the consumption of liquid nitrogen is extremely low, and two samples can be processed simultaneously. A cryogenic option is available to support this economical cooling method.

The Model 200 dimensions are 11 3/4" w x 7" h x 18 1/4" d. The Model 400 dimensions are 11 3/4" w x 9" h x 18 1/2" d. Inquire for current pricing. Specify 110V or 220V.
