Melt Point Apparatus

Melting point range is an important factor for determining the identity and purity of compounds, which is the primary focus of many college synthetic chemistry labs. The built-in magnifying eyepiece allows students to observe the melting process individually. You can add a USB camera (sold separately) to record the process for real time viewing on a larger screen or replay for a more confident determination. The variable ramp rates allow you to quickly raise the sample temperature near melting (to preserve lab time) before slowing the rate down again, and the hold temp command ensures all substances reach a uniform temperature without surpassing the melting event. Check the current temperature easily with the built-in temperature sensor, and use the cooling fan between measurements to quickly restore the heating block to room temperature.

What’s Included

• 1x 110 – 220v power source
• 1x 3 x viewing eyepiece
• 1x Melt point determination tubes (pkg 100 count)
• 1x Cool down fan
• 1x 50 W heating unit for precise temperature control
• 1x Variable rate heating control profile in PASCO software (available separately)
• 1x 3 sample holding block for controlled heating

Features

• Quick ramp: max temperature raise to melting point. Tail off rate is applied near target to prevent mp overshoot.
• Hold: ensures system temperature is uniformly close to melting point before proceeding.
• Prompt: requests permission to continue to ensure student is ready to observe in detail.
• Start Image Capture (in Capstone and chemvue): controls capture rate from 5 seconds.
• Ramp: allows user to set a slower warming rate through melt point for improved accuracy.
• Stop Image Capture: turns off periodic capture at goal temperature or record is stopped.
