Description
Product Overview and Application:
 
The Digital Melting Point Apparatus Model 935, manufactured by Electronics India (EI), is a specialized laboratory instrument designed for the accurate measurement and observation of melting points and melting ranges of solid samples. The determination of a substance's melting point is crucial for identifying pure substances and verifying sample purity in various scientific fields.
This apparatus is particularly useful for the Pharmaceutical Industry, where assessing the purity of active pharmaceutical ingredients (API) and ensuring adherence to specifications is vital for drug safety and efficacy.
Advanced Measurement Technology
The Model 935 is engineered for high accuracy and ease of operation. It uses a digital temperature indicator equipped with a PT100 RTD sensor.
 
Precision Heating and Temperature Control:
 
The core system involves a 200 ml capacity silicon oil-bath covered with a PTFE or Teflon cover. Uniform heating across the bath is ensured by an in-built magnetic stirrer, with the stirrer speed being controllable via a front knob. An electronic controller allows for precise adjustment of the silicon oil-bath heating rate.
Digital Display and Resolution
Model 935 offers high resolution and clear visibility. It utilizes a 4 Digit, 7-Segment LED Display. The digital readout provides a high resolution of 0.1 °C, enabling precise recording of the melting range.
Observation and Operation
The apparatus features a large magnifier and a glare-free background illuminator to facilitate stain-free observation of the sample as it melts inside the capillary tube.
 
Operational control includes:
 
• Start Switch: Used to initiate the measurement of the melting point.
• Stop Switch: Used to halt the measurement once the sample has melted, with the display showing the last temperature recorded.
• Clear Switch: Used to reset the display reading to zero.
