The Smart VacPrep is an advanced six-port system that utilizes vacuum to prepare samples by heating and evacuation. Each of the ports may be operated independently. Samples may be added or removed from degas ports without disturbing the treatment of other samples undergoing preparation. Degassing automatically terminates when the samples have completed all programmed steps.

The SmartPrep 065 is a flowing-gas degassing unit which removes adsorbed contaminants from the surface and pores of a sample in preparation for analysis. It contains six sample ports, each one independently temperature-controlled for greater flexibility. It contains two serial ports, one for connecting to the computer and the other available for connection of an additional SmartPrep. The temperature, ramp rates, and soak times of each sample are individually controlled by the computer. Up to five ramps and soaks are allowed. All degas information is integrated into the sample data file for future reference.

The VacPrep 061 offers two methods for removing contaminants. In addition to flowing gas, it provides vacuum to prepare samples by heating and evacuation. This combination allows you to choose the preparation method that is best suited to your material or application. The VacPrep features six degassing stations, and a choice of vacuum or gas flow preparation on each of the six stations. Needle valves are also provided allowing you to introduce the flowing gas or vacuum slowly to prevent fluidization of samples.

The FlowPrep 060 applies both heat and a stream of inert gas to the sample. The heat causes contaminants to desorb from the surface and the stream of inert gas sweeps them out of the sample tube. It lets you choose the temperature, gas, and flow rate best suited for your sample material and application. Needle valves allow you to introduce the flowing gas slowly to prevent fluidization of samples.

For use with the ASAP 2060, the MicroPrep allows in-situ final degassing of micropore samples to assure that the sample is meticulously cleaned of any adsorbed contaminants prior to analysis. The MicroPrep features a high-quality digital control unit to regulate the heating mantle to the desired set point temperature.

The Model 021 LN2 Transfer System allows you to transfer liquid nitrogen or liquid argon from a nonpressurized storage Dewar into smaller containers as needed in laboratory experiments. The system was specifically developed for conveniently filling Dewars for gas adsorption instruments but also can be used for other cryogen applications. The Model 021 can discharge cryogens at adjustable rates up to 3 liters/min. The roller base makes it easy to move the 021 System to the location where the cryogen is needed. The nozzle and insulated, flexible hose enable convenient filling and refilling of analysis Dewars. The system can hold liquid nitrogen or argon up to 30 days allowing cost-efficient use of your cryogen.

It is the same as if a human operator had filled the mixing chamber with predispersed sample. After the analysis is started, the MasterTech’s stirrer rotor, ultrasonic probe and transfer tubing are all back-flushed with clean liquid and made ready for the next analysis cycle. The arm will raise so that the rinse liquid will remove any sample remaining on the stirrer rotor and probe, and in the transfer tube. When analysis is complete, the contents of the mixing chamber are pumped to the waste container, and the MasterTech will automatically proceed to the next sample. The process will continue without the need for operator intervention until the particle analysis system has completed all requested analyses.

Particle size measurement instruments typically employ deionized or even untreated water as a suspension medium for particle dispersion during analysis. Usually, this water contains undesirable levels of dissolved gases, most often those commonly present in the atmosphere. During analysis, these gases can come out of solution, forming minute bubbles that can have important effects on the analytical results. Regardless of the relative size of the bubbles, their presence distorts the reported distribution of sizes; it also degrades the repeatability of analyses.

The Micromeritics ElectroPrep is a highly effective system for the preparation of contaminant- free electrolyte for use with the Elzone II and other instruments. If you are looking for an easy-to-use electrolyte filtering device to ensure high-quality particle size data, then Micromeritics’ new ElectroPrep 053 is a necessary addition to your laboratory.

The Chiller Dewar is easily mounted to the system’s elevator using the supplied clamping screw and bar set. The unit comes complete with all necessary fittings and tubing for connection to the recirculating bath. An external RTD is also provided which mounts inside the dewar. The RTD connects to the recirculating bath and ensures that precise temperature control is maintained over the course of the experiment.

FP25-ME  These units provide efficient heating/cooling. With Active Cooling Control to +200 °C ‚ this model offers proportional cooling control to ensure energy-saving performance and reduce heat generation.

Micromeritics’ CryoCooler II accessory for our AutoChem series provides temperature control from -100 to +1100 °C. The device permits ramping temperatures at rates from 5 to 50 °C/minute, selectable in 1 °C increments. The CryoCooler II seamlessly transitions from sub-ambient to ambient operation. A source of LN2 is directly attached to an AutoChem furnace for rapid cooling and cycling of the furnace.

The Cryostat I eliminates the need for liquid nitrogen and can obtain temperatures below the 77 K of liquid nitrogen. The unit is mounted on the Micromeritics instrument with a specially designed fixture. The cold head of the device is positioned at the unit to maintain precise temperature control of the sample tubes. The Cryostat I’s cold head is then connected to a floor mounted compressor.

The sample area will accommodate up to 3 sample tubes. Heat removal is uniform and accurate when the unit is used with an appropriate liquid (ambient water or liquid antifreeze). The dewar section is placed on the instrument dewar elevator and then raised into position for analysis.

The SSSPin Tester provides repeatable and consistent data by first consolidating the material using centrifugal force to compress the sample inside the sample holder. After the initial compaction step, the SSSpinTester then completes the analysis routine using the same centrifugal force to determine the yield strength of the material.
