Our Products

PITT-3

We design, build, and sell custom PITT-3 type fluidized bed aerosol generators with built-in amplifiers and flow controllers. The drivers for these units are fully enclosed, and the generators are built of easily-decontaminated 316L medical grade stainless steel with stainless steel, aluminum, or Teflon diaphragms and TFE gaskets.

Unique air-injection methods make these units exceptionally controllable. Ongoing research indicates that concentrations in the range of several mg/m3 are easily maintained for long periods of time in closed systems using these generators.

Variable waveforms can be used to drive the generators from almost any computer or audio signal generator.

Generators in this series range from 0.25 to 25 LPM output. Particle size distributions can be controlled by using well defined input materials, such as Celite(R) 545, talc, Arizona road dust, fluorescein, grain dust, Bg and dry polystyrene microspheres. You can also aerosolize your own materials or reaerosolize particles captured by air sampling.

Custom Aerosol Inlets

We designed and build aerosol inlets used on biosamplers used by the Department of Homeland Security.  We  are a proud distributor for VNE Stainless, Inc.
Please contact us if we can help design and build a system for you.

AlburtyLab Virtual Cyclone Concentrator

The Virtual Cyclone Concentrator (VCC) operates similarly to a normal reverse flow cyclone, except that a small amount of air flow is drawn from the bottom collector cup, or “minor flow”. Inertial forces and cyclone function combine to multiply the concentration of aerosols with diameters from 0.5 microns up to 10 microns in the minor flow.

Key Benefits
* Target particle enrichment of over 20X has been demonstrated for sizes below 10 microns aerodynamic diameter
* Commercial systems can be adapted to VCC configuration
* Scaling of VCC demonstrated from 3-8500 LPM(major flow) and 0.1-450 LPM (minor flow)

Capabilities of VCCs
A VCC can be custom-designed or an existing system can be modified to function as a VCC. System flowrate and concentration band required is determined first. Then, a mathematical model is constructed, the device is built to specifications, and demonstrated over a range of flowrates and particle sizes to verify its performance.

Several VCCs have been built using both methods and implemented for aerosol concentration. Research into the factors controlling the concentration band is ongoing.
