MPA120 Automated Melting Point Apparatus

EZ-Melt is a fully automated melting point apparatus that determines the melting points of chemical substances. It’s fast, accurate, and very easy to use. You simply enter the start temperature, stop temperature, ramp rate and press Start. It’s that simple!

Absolute Value

EZ-Melt is priced far below any other automated system, as well as most manual systems. It provides the absolute best value of any commercially available melting point apparatus.

Automated Operation

Unlike time-consuming manual melting point systems, EZ-Melt is specifically designed for unattended (automated) operation. During a melt, a closed-loop PID algorithm controls temperature ramping, and a built-in digital camera continuously monitors your samples as they melt. Using digital image processing technology, images are analyzed and the melting points (clear point and onset of melt) are determined. Results are read on the large 4-digit LED display.

Temperature Tagging

Samples can be viewed at any time using the built-in magnification lens. During a measurement, you can flag relevant events by pressing the Left, Center or Right front-panel buttons. Up to four individual temperatures can be tagged for each sample.

Precise Temperature Control

The small, aluminum oven design, along with microprocessor-controlled temperature ramping, allows fast and repeatable warm-up and cool-down cycling. Ramp rates from 0.1 ºC/min. to 20 ºC/min. (1-2-5 sequence) provide the flexibility needed for virtually any melt.

Accurate Results

EZ-Melt uses a platinum RTD sensor to make temperature measurements to 400 °C with 0.1 °C resolution. It is easily calibrated in the lab using certified reference standards, and complies with modern Pharmacopeia protocols.

Affordable Precision

EZ-Melt is the fast, accurate and affordable solution to melting point measurements. Don’t waste time with a manual system — use EZ-Melt!
