Melting Point Apparatus MPA160

DigiMelt is a modern, low cost, digital melting point apparatus designed specifically for the student lab. Students learn the visual detection capillary method of melting point determination without the frustration of trying to control the oven temperature. DigiMelt rapidly heats the oven to the programmed start temperature, then ramps at the specified rate. The student carefully observes the samples and records the melting points with a touch of a button

Tube Tapper

For many students, the melting point lab is the first time they have touched a capillary. This can lead to lots of capillaries on the floor and many broken capillaries. DigiMelt employs an integral cell phone vibrator motor to let students pack their sample without tapping them on the bench or dropping them through a long glass tube. A molded guide in the chassis allows students to pack three samples at a time.

Easy Maintenance

Cleaning the lens is as simple as removing the lens retaining ring. If a student should break a capillary, the entire lens holder assembly slides out for easy clean up of the broken glass. Replacing thermometers is a thing of the past as the RTD will never break and cannot be removed from the instrument. Unlike conventional incandescent bulbs that must be periodically replaced in some student instruments, the white LEDs used in DigiMelt will last a lifetime.

Safer for Students

The DigiMelt uses an internal RTD thermometer, which means students and TAs are never exposed to toxic mercury vapors. Some student instruments will reach 500 °C and stay at that temperature indefinitely — a severe burn hazard. The DigiMelt’s maximum temperature is 260 °C, which allows testing of virtually all organic compounds a student might examine. Intelligently designed cowling protects students from touching the hot oven. Furthermore, the oven will automatically turn off after being idle for 30 minutes.
