Stainless steel Micro vials are used for cryogenic grinding of small sample amounts or for standard grinding applications of small samples such as soil or grain using a steel or tungsten carbide bead. Steel vials ensure a much higher heat transformation in order to optimize the heating and cooling. The stainless steel Micro vials are available with a grinding ball pre-filling optional.

Designed for high analytical screening, the LAB WIZZ efficiently and safely disrupts samples of spores, microorganisms, plant and animal tissue, or soil samples at a time.

The samples along with extraction media and small metallic or ceramic balls are placed in micro vials. After 2 minutes of preparation in the LAB WIZZ more than 95% of the cells are disrupted. Because balls and vials plates are disposable the method is ideal for PCR, PAGE, and Probe applications where cross-contamination between samples cannot be tolerated.

Ice bath for cryogenic grindingmixer mill - high energy ball mill (27)

For heat-sensitive materials such as plastics and rubber, it is possible to embrittle the material with liquid nitrogen and perform additional external freezing of the fast clamping jars. Those jars are either made from Teflon or from stainless steel and are suitable for cryogenic grinding applications.

Cryogenic Ball Milling

The New Mixer Mill the optimal device for the preparation of small quantities. Due to its universal character the Mixer Mill is used for a great variety of applications in biology, chemistry, pharmaceuticals, environment, ceramics and mineralogy. It performs fine and ultra-fine grinding of not only hard, medium hard and brittle samples such as alloys, bones and glass but also elastic and fibrous ones like plastics and hair. The mill is ideally suited for disrupting biological material for the isolation of DNA and RNA. With a maximum feed size of up to 8mm a grind size of down to 5 microns can be realized. The screw top design of the grinding jars prevents leaks so that even wet comminution can be executed simply and without any sample loss. Defined positioning of the grinding jars and the clamp with automatic centering ensures a maximum degree of reproducibility. The optimized self-locking clamping device simplifies handling of the jars and supports the safety aspect of this device significantly, two grinding stations for jars up to 50mm allow high sample throughput. The grinding time as well as the oscillation frequency of up to 30HZ can be preselected digitally and precisely.

An electronic speed control keeps the vibration constant during the entire grinding process. The user has the option to save up to 9 parameter settings which offer ultimate convenience in routine testing of various samples. During the grinding process the parameters are then safe from any accidental changes. At the same time this guarantees maximum reproducibility of the sample preparation process, after starting the machine the sample containers perform radio oscillations in a horizontal position, thus the material is hit alternately from various sides by the grinding balls. This high energy impact and friction action makes the Mixer Mill one of the most efficient grinders on the market. Compared to traditional mixer mills ours provides an enlarged oscillation radius on account of this a significantly higher grinding energy is applied to the sample which leads to a drastic reduction of the grinding time. Opposing action of the jars ensure stability even at maximum oscillation intensity, the whole sample is recovered. Standard applications that the Mixer Mill is used for are for example spectral analyses like XRF, ICP or AAS; subsequent pelletizing or fusion is directly possible. The Mixer Mill is therefore also and economical and ergonomic alternative to the widely used Pac and Dish Mills. Furthermore this multi-functional device can also be used for wet grinding, cell disruption and cryogenic grinding. The screw top grinding jars offer an ideal prerequisite for wet grinding; an additional teflon ceiling prevents leakage of liquids and particles. Smaller sample volumes as commonly used for the isolation of DNA and RNA are preferably prepared in disposable reaction vials such as those from eppendorf.

For this purpose adaptor racks are available and hold up to 10 reaction vials, by using grinding media of glass for instance cell disruption is affected in an extremely short time which makes additional cooling unnecessary. Temperature sensitive and elastic materials can be successfully processed by external cooling of the grinding jars, for this purpose a special cryo kit consisting on two cryo boxes, two grinding tongs and protective spectacles is available. With this equipment we offer the easiest and most efficient way of grinding the ungrindable with only little consumption of liquid nitrogen, In contrast to cryogenic grinding conducted by other mills neither preparative nor continuous cooling are necessary. The grinding results are greatly influenced by the choice of grinding accessories. Jar volumes and ball charges as well as their materials should be selected according to the nature and quantity of the sample to be ground, in order to avoid interference of the subsequent analysis. To optimize your specific grinding process the Mixer Mill offers an unrivaled variety of jars and balls ranging from 1.5mm -50ml and from 5mm-30mm, both are available in agate, hardened steel, zirconium oxide, tungsten carbide, stainless steel and teflon. Grinding balls and glass beads for use in reaction vials are available in sizes from 0.1mm-5mm. A huge amount of unique features determine the superiority of the new Mixer Mill . The convenient bench top unit is the ideal grinder to prepare small sample volumes. Our Mixer Mill is an easy to use, universal and at the same time powerful tool to conduct perfect sample preparation, it is the optimal solution to get reliable and reproducible results for your grinding, mixing, homogenizing and cell disruption process.
