	NIR Transmission Spectroscopy Precision Heated Cells - Series HNIR
Series HNR-1 Near Infrared cell. Note a window is mounted into the 3"x2" industry standard card and also the close fitting lid. The cell can be water cooled - the red tubes are for this purpose.

The newly developed Ventacon Model HNIR-1 cell system fills a gap in the market - a near infrared transmission cell system able to accommodate path lengths between 5 and 20mm heated and controlled very precisely to preset temperatures between 40 and 185° C.

The cell unit is capable of holding cuvettes between 5 and 20mm in path-length. The kit includes four cuvettes - 1 x 5mm, 2 x 10mm and 1 x 20mm in quartz or glass. Each cuvette is supplied with a PTFE lid. The very precisely made oven holds these cuvettes, is mounted on an industry standard 3"x2" "card" and is controlled by our Ventacon D II Series Universal Power Supply or the Ventacon D 5 high temperature cell power supply. Although we only claim a precision and control of ±½°C, most customers achieve ±0.1°C or even better on operation. To achieve this performance, the cuvettes are lightly clamped into an aluminium alloy oven. Obviously, air circulation would ruin the quality of the temperature control thus a close-fitting lid is supplied to minimise this problem.

HNR-1 Near Infrared cell - lid removed. 3 cuvettes and one spacer stand in front of the cell. A 10mm cuvette and spacer are fitted in the cell.
