IR Transparent Silicon Plates

Silicon has a substantial transparency throughout much of the infrared region of the electromagnetic spectrum. Therefore silicon can make an ideal substrate or sample holder for the parallel measurement of samples with infrared radiation by transmission or reflection. Since silicon is oxidatively and chemically quite stable, measurements at elevated temperatures are easily achieved. The high chemical stability of silicon will obviously facilitate cleaning of the substrates, so repeated use of the plates is possible.Several plate configurations are possible including silicon microtiter plates which can be prepared with flat or tapered wells at any standard SBS density (384, 1536 and 6144 formats available for shipping). The silicon which constitutes the well bottom can be machined to near micron thickness generating IR transparency suitable for most transmission or reflection experiments.Silicon filter plates suitable for the handling and manipulation of various polymer beads are also available. Filtration, isolation and measurement of the infrared spectra of the beads can be condensed to one operation allowing facile high throughput measurements on a single substrate. Since it is very easy to micromachine grooves and trenches into the silicon substrate, configurations and substrates involving parallel channels for separations or fluid handling can be readily prepared.
