The Spex 8000D CertiPrep mill is a two-clamp lab mill that can be used for pulverizing rocks, minerals, sand, cement, slag, ceramics, catalyst supports, and hundreds of other brittle, often hard samples in the 10-gram range. This model is a variant on the ball mill or jar mill, which grinds samples by placing them in a container along with one or more grinding elements, and imparting motion to the container. Generally the containers and grinding elements are made from the same material. As the container is swung, the inertia of the grinding elements causes them to move independently, into each other and against the container wall, grinding the sample. The Spex 8000D is best described as a high-energy ball mill and is capable of rapidly shaking containers back and forth several thousand times a minute and features a variable-range electronic timer, forced-air cooling, and a safety interlock. To operate, a vial containing the sample and a ball or balls is secured in the clamp and swung energetically back and forth. The back-and-forth shaking motion is combined with lateral movements of the ends of the vial, so that the vial appears to be describing a figure-8 or infinity sign as it moves. The length of that swing is the same as the internal length of the vial, about two inches. With each swing of the vial the ball impacts against the sample and the end of the vial, both milling and mixing the sample. Because of the amplitude and velocity of the clamp’s swing, each ball develops fairly high G-forces, enough to pulverize the toughest rocks, slag and ceramics. Vials are sold separately (available from Spex or your local distributor) and are of a variety of different materials, including steel, tungsten carbide, agate, zirconia, silicon nitride, alumina, and heavy-duty plastic.

Most of our equipment is used and reconditioned. Our technicians test ovens using a calibrated digital chart recorder to verify the accuracy of temperature controls and readouts and run the unit under vacuum to insure chamber integrity. We typically leave an oven under vacuum for 24 hours to make sure the pressure holds. We replace any hardware or parts as is necessary and clean all incubators thoroughly prior to shipment.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.

FAQ

Does the equipment come with a warranty?

Yes, all equipment from American Instrument Exchange comes with a warranty.
Used/reconditioned/refurbished equipment is tested to make sure it operates to the manufacturer’s specifications and comes with a 90-day warranty (unless otherwise noted). New equipment comes with a warranty from the manufacturer.

How do you test and recondition the equipment?

Testing requirements vary across all the equipment categories we sell. Temperature controlled units are tested with NIST traceable probes and data loggers. Gaskets, external housing, glass, handles, controls and control screens are all thoroughly inspected for integrity and functionality.
We test all equipment using the manufacturer's parameters and specifications to confirm that the unit operates properly. While we may not be able to test for specific analytical applications we do our best to simulate the conditions under which the equipment will be used in your lab. If you have particular testing requirements please let us know and we’ll work with you to make sure these are addressed during testing.

How do products ship from American Instrument Exchange?

We can ship products both nationally and internationally using a well-established network of transporters. Smaller items will ship via UPS.

All shipments are FOB Haverhill, MA. American Instrument Exchange will take reasonable steps to protect the equipment during shipment and the equipment will be fully insured. The customer will be charged for all shipping and handling charges, and fees incurred in the process of delivering the order.

For local customers in and around New England we can offer shipping and delivery using a local moving company trained by our staff to handle and deliver lab equipment. Our local movers can provide either standard dock-to-dock delivery or bring the equipment into your lab and set it in place.

This is the standard for all transportation so we want to protect you, our valued client.
