They feature heating block that ensures uniform thermal distribution. Their construction includes capillary tube that holds sample in place for accurate determination. They include optical system to clearly observe transition of sample. Our Touch Screen Melting Point Apparatus is suitable for purity testing, compound characterization, environmental analysis and forensic analysis.








Labtron supplies premium melting point apparatus LDMP-A31. Accurate melting point determination starts with properly prepared samples. Use dry, finely powdered solids loaded into a capillary tube to about 2–3?mm depth; crushing larger crystals helps ensure uniform packing and thermal contact. Avoid contamination by using clean tubes and drying hygroscopic materials beforehand, as residual solvents can lower and widen the melting range. Gentle tapping or centrifugation removes air gaps, ensuring consistent heat transfer. Proper prep improves repeatability and accuracy, reducing outliers and misleading readings.
Labtron supplies premium melting point apparatus LDMP-A 31. Set the initial “plateau” about below the expected melting point for preheating, then switch to a slow ramp as melting begins. Fast initial heating saves time while the slower rate near melting delivers sharper transitions and narrower ranges. Most pharmacopeia and software-guided devices recommend a consistent 1?°C/min ramp through the melting interval. Following these settings minimizes superheating and thermal lag, ensuring accurate and comparable results.
Labtron supplies advanced models of melting point apparatus LDMP-A31. Effective sample preparation starts by grinding your substance to a fine, dry powder to achieve uniform particle size, ensuring consistent thermal behaviour. The powder should be carefully packed into a clean capillary tube, avoiding air gaps and external residue that could impact heat transfer or contaminate the instrument. Gently tapping the tube helps settle the sample at the bottom of the capillary, promoting precise melting transitions and reducing variability caused by uneven packing or moisture.
Labtron supplies premium melting point apparatus LDMP-A31. Overheat protection automatically shuts off the heater if the temperature climbs beyond a safe threshold. This prevents damage to internal parts like thermocouples, heaters, and insulation. It also raises a warning alert to the user. This safety feature is crucial if a sample dries, the block is empty, or there's a malfunction. By avoiding uncontrolled heating, it reduces fire risk and extends the lifespan of your instrument by preventing thermal stress and component failure.
Labtron supplies premium melting point apparatus LDMP-A31. Accurate melting point measurements depend on how the sample is both heated and cooled. Automatic cooling systems-like built-in fans or Peltier modules-bring the apparatus back down to starting temperature quickly and evenly. That way, each new sample starts from the same baseline. Rapid, controlled cooling also preserves the calibration of the heating block by preventing overheating. In contrast, slow or uneven cooling could cause drift, unpredictable heating behaviour, and inconsistent results over time.
