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.
Description:
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.
Specification:
Capacity: Six ports
Degas Method: Heat and vacuum
Vacuum Control: Servo-controlled rates to minimize or eliminate sample elutriation
Evacuation Rate: Selectable evacuation rate from 1.0 to 50.0 mmHg/s
Heating of Samples: Heating mantles
Temperature Range: 40 to 450 ºC in one degree increments
Temperature Control: One ramp during evacuation phase, five additional ramps during subsequent phases
Temperature Accuracy: Deviation less than ±10 ºC at the sensing thermocouple embedded in the heating mantle
Heating Ramp Rate: Selectable from 0.1 ºC per minute to 10 ºC per minute
Hold Time: Zero to 999 minutes in one-minute increments
Backfill Options: Automatic backfill
Dimensions: Height 69 cm (27 in.), Width 53 cm (21 in.), Depth 43 cm (17 in.)
Weight: 70 lbs (32 kg)
Description:
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.
Specification:
Sample Tubes: Up to 3.0-cm (1 3/16-in.) OD bulbs with 1/4-, 3/8-, or 1/2-in., 9mm, 12mm OD stems.
Heating Block:
Temperature: 10 ºC above ambient to 400 ºC
Temperature Accuracy: ±10 ºC
Electrical:
Voltage: 100, 120, 220, 240 VAC r10%
Power: 250 VA maximum
Frequency: 50/60 Hz
Environment:
Temperature: 10 to 35 ºC operating; 0 to 50 ºC non-operating
Humidity: Up to 90% relative, non-condensing
Gases Used: Helium, nitrogen, argon, or any other pure gas that does not adsorb at room temperature.
Flow Rate (flowing gas preparation): Up to 50 cm3/min.
Vacuum System:
A vacuum source achieving better than 20 µmHg at the instrument inlet, and having a device to reduce oil vapor
backstreaming is recommended.
The vacuum system must also have an anti-suckback valve to prevent oil from flowing into the VacPrep should there be a power failure.
Sample Capacity: Six ports, each with a heating and a cooling station
Physical:
Height: 43 cm (16.95 in.)
Width: 36 cm (14.3 in.)
Depth: 30 cm (11.87 in.)
Weight: 10 kg (22 lbs)
Description:
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.
