OPTI-SCIENCES ACM-200

Opti-Sciences ACM-200 plus Anthocyanin Content Meter • Study anthocyanin content in leaves and flowers Non-Destructive Measurement • Monitor Sugar Maple Senescence • Anthocyanin has be shown to enhance plant pest protection and photoprotection. Features • Up to 160, 000 measurement storage • Display Anthocyanin Content Index and Calculated Sample Averages • USB output • Lightweight, Hand-Held Design Optimized for Field Work • Built-in Data-Logging • Graphic data display • Stand Alone Operation- No P.C. Required The ACM-200 plus Anthcyanin Content Meter provides a fast estimate of anthocyanin content on the intact leaves of plants and flowers. Reduce grinding or destructive assays! The measurement is rapid, nondestructive and simple to obtain, allowing researchers to gather reliable data that has been shown to correlate to chemical testing. The ACM-200 plus is designed to be highly reliable and long lasting. It incorporates a large measuring area for signal averaging over a large sample area. This approach provides a reading that takes into account small structure variations that can affect repeatability and reliability when compared to a smaller sampling area. The ACM-200 plus is the successor to the CCM-200 anthocyanin meter, an instrument that was introduced in the year 2005. The ACM-200 plus has the large on-board memory, storing up to 160, 000 measurements or up to 94, 000 measurements with GPS Data internally. Users can record large amounts of measurements without concern as the data is stored in non-volitile flash memory. Downloading of data is quick and easy through its universal USB 1.1. port. The ACM-200plus does not require external data loggers. All you need for precise anthocyanin measurements are included in one lightweight, compact, affordable package. Changes in anthocyanin content can occur over time. Research has shown that the anthocyanin meter can provide a reliable and fast estimate of anthocyanin. Studies have been done on Sugar maples, Clitoria ternatea, Desniodium adscendens, Corchorus olitorius, Catharanthus roseus, and Hibiscus sabdariffa. Other research is on going. Laboratory methods for determination of anthocyanin content are both time consuming and destructive to the sample. Typically, a sample must be detached, ground up in a solvent, then assayed in a spectrophotometer. With chemical testing, sample can be measured only once, precluding the cost effective monitoring of trends in anthocyanin content over the life cycle. References Morris J.B., Wang M.L.
