Wireless Melting Point Apparatus • PS-3239

Melting point is an important property for determining the identity and purity of compounds, which is an important focus of many college synthetic chemistry labs. The built-in 3x magnifying eyepiece allows students to observe the melting process easily. You can add a USB eyepiece camera (SE-6215-sold separately) to record the process for real time viewing on a larger screen in all our software or for replaying the time synched images (in capstone) for a more confident determination. The variable ramp rates allow you to quickly raise the sample temperature in the software before tailing off near melting and the hold temp command ensures all substances reach a uniform temperature without surpassing the melting event.  Software then allows the user to choose a timed ramp to control the rise through the melting point and accurately note the melting temperature before the cooling fan quickly restores the heating block to room temperature.   Additional commands allow the user to control a separately purchased camera (SE-6215) to start and stop the image collection at controlled rates when wanted. The playback feature in Capstone allows the user to confidently choose starting and end temperatures of the melting process.  In SPARKvue and chemvue, the time stamp on the image allows you to look up the melt temp on the associated graph.
