Melting Point Apparatus OptiMelt — Automated melting point system · Stand-alone operation and computer control (USB) OptiMelt provides a fast and accurate means of automatically determining the melting points and melting ranges of chemical substances. Up to three samples can be analyzed simultaneously. A wide observation window, with an illuminated magnification lens, allows users to observe the samples at all times. A small aluminum heating block is kept under tight computer temperature control, providing extremely linear temperature ramping. A precision Pt RTD sensor provides fast and accurate temperature readings from room temperature to 400 °C with 0.1 °C resolution. Automated Measurements · Printer output OptiMelt is specifically designed for unattended operation. It has a built-in digital camera that continuously captures real-time images of the samples, and it uses digital image processing to determine results. The melting points and melting ranges are prominently displayed on the front panel and automatically recorded into memory for later review. · Completely automated operation · PID-controlled temperature ramping · Digital movie of each melt OptiMelt provides a dramatic improvement over instruments that rely on optical absorption or reflection techniques. OptiMelt’s high-resolution camera can easily detect minute changes in the optical characteristics of the samples, eliminating the need for an operator to be present. Stanford Research Systems Simple Operation OptiMelt has an intuitive front panel and is very easy to use. You simply select the start temperature, ramp rate, stop

Distinct beeps and bright, front-panel LEDs announce important events like temperature stabilization or end of melt. Two separate glass holders, located on top of the instrument, are available to store empty or discarded capillary tubes. Four, nearly indestructible, white-light LEDs provide constant illumination of the sample chamber. Samples can be viewed on the front panel through a removable magnification...

MPA100 Automated Melting Point System MeltView Software The MeltView software allows you to display live, high- resolution images of your samples during analysis. The three screen-captured images below were collected during a typical melt. Figure 1 shows the unmelted solid samples, figure 2 reveals the meniscus point, and figure 3 corresponds to the end of the melt (clear point). Stored images may be recalled at any time, and can be played back frame-by- Average time perframe (ms Figure 1 — Solid samples /jjSRs Melt ■■■■■■ ■■■■■■■■■■ ■■■■■ ■■■■■■■■■■ ■■■■■ ■■■■■■■■■■ ■■■■■ ■■■■■■■■■■ Oven Control...
