About DIGITAL MELTING POINT APPARATUS 934 & 935

FEATURES

· Extremely Useful for Pharmaceutical Industry

· Highly Accurate & Easy to Operate

· 4 Digit 7-Segment LED Display

· Digital Readout for Temperature 0.1 °C (Model - 935) and 1 °C (Model - 934)

· Silicon Oil-Bath and In-built Magnetic Stirrer for Uniform Heating

· Glare-free Illuminator and Large Magnifier for Stainfree Observation

Melting Point Apparatus with 4 digit, 7-Segment LED display is designed for accurate measurement of melting points and for checking the melting range of the solid samples. The apparatus consists of a silicon bath of about 200 ml capacity, covered with Ptfe cover with 3 holes fitted, with a special type of oil immersion heater having three holes for holding the capillaries, one for boiling point tube and one for the thermometer. The apparatus consists of in-built magnetic stirrer, an electronic controller with indicator for precisely adjusting the rate of heating of silicon oil-bath, an ON/OFF switch, a pilot lamp, with magnifier, a glare free background illuminator, a High/Low range temperature selector switch and digital temperature indicator with PT100 RTD sensor

The 'Start' switch is used to start the measurement of melting point. User can sto the measurement using the 'Stop' switch after the instrument reaches the melting point of the sample. The display will always show the last temperature where 'Stop' switch pressed in the last measurement. Clear switch is used to clear the display to zero.

FAQs of DIGITAL MELTING POINT APPARATUS 934 & 935:

Q: How does the DIGITAL MELTING POINT APPARATUS 934 & 935 ensure accuracy during measurements?

A: These models utilize a microprocessor-based temperature controller and a digital display that allow precise setting and monitoring of temperature. The built-in magnifying lens and clear viewing window provide detailed observation of samples. Together, these features ensure 100%% accuracy when determining melting points.

Q: What is the process for determining the melting point with these apparatuses?

A: Simply insert up to three capillaries filled with your sample into the holder, set your desired heating rate (between 1C/min and 10C/min), and observe through the magnifying lens as the temperature rises. When the substance melts, both digital and light indicators will trigger, accompanied by an audio alarm.

Q: When is manual cooling required, and how is it done?

A: Manual cooling is required after completing a melting point determination, particularly when the chamber temperature is high and a new set of samples needs to be introduced. Wait for the chamber to cool naturally, or expedite cooling using the manual cooling system as directed in the user manual.

Q: Where can this apparatus be used most effectively?

A: The DIGITAL MELTING POINT APPARATUS 934 & 935 is ideal for laboratory environments in educational, pharmaceutical, or research settings across India, where precise and reliable melting point analysis of substances is essential.

Q: What are the main benefits of using this melting point apparatus?

A: Key benefits include high efficiency, the ability to test three samples simultaneously, a fully digital and audio indication system, superior accuracy, durable corrosion-resistant construction, and comprehensive built-in safety features for worry-free operation.

Q: How does the apparatus enhance laboratory workflows?

A: By accommodating multiple samples at once, providing rapid heating rate adjustment, and offering both digital and light indicators along with audio alarms, these models accelerate routine analyses and reduce supervision time, making laboratory workflows more productive.
