Micromeritics’ sample preparation devices prepare batches of samples for surface area and pore volume analysis. They combine flowing gas and/or vacuum with heat to remove atmospheric contaminants, such as water vapor and adsorbed gas, from the surface and pores of the sample.

The quality of the data produced by surface area and pore volume analyses depends greatly on the cleanliness of the sample surface. All Micromeritics’ sample preparation devices accept helium, nitrogen, argon, and other non-corrosive gases.

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 In-Situ Degassing

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.

Specifications:

  • Temp Range: Ambient to 250 °C
  • Temp Accuracy: +/- 5.0 °C
  • Ramp Rate: 10 °C
  • Electrical: 100–240 VAC, 50-60Hz

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.

AquaPrep II - for Saturn DigiSizer II

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.
