A revolution in microspectroscopy – The membrane was specifically developed and patented for use in microspectroscopic analysis. Thanks to filtr.AID, traditional time-consuming microparticle preparation techniques using needles or even tweezers are now a thing of the past. After separation, the microparticles remain on the membrane where they can then be identified using Raman. ID or EDX spectroscopy.

Certified Cleanliness – The filtr.AID membrane is produced, controlled, and packaged individually under cleanroom conditions. The batch inspection certificate guarantees batch cleanliness for the user.

Easy handling – An aluminum ring around the membrane ensures easy handling during sample preparation and measurement. Samples can easily be archived and transported in a petri dish (provided along with the membrane.)

Precise image analysis – With rap.ID's darkfield illumination technique, particles approximately 500 nm and larger in size can produce excellent contrast against the membrane surface, making this method an ideal means for determining particle size distribution.

Precise and standardized – Centers the diameter of the active area. The diameter of the active area is adjustable from 1 to 18 mm.

Flexible samples – Even substances with extreme pH values and aggressive solvents with sample volumes from a few hundred microliters to several hundred milliliters can be quickly filtrated using filtr.AID. rap.ID's "filtr.AID airbone" is designed for air or gas sampling.

Qualified quality – Method validation shows that over 99% of all particles 2µm and larger are separated within this area.

Easy handling – Easy cleaning and fault-tolerant operation ensure reproducible results.

Experience and reliability – rap.ID Particle Systems ensures high quality products and services due to the experience and innovation compiled over the past years in cooperation with other highly reputable companies and universities. rap.ID's partners worldwide can arrange service and distribution.
