Requirements for determining the boiling range of volatile organic liquids

Thread Content

The SY7534 boiling range analyzer is designed and manufactured in accordance with the requirements specified in the standard GB/T7534-2004 \"Determination of boiling range of volatile organic liquids for industrial use\"; it is an instrument suitable for determining the boiling range of volatile organic liquids used in industry as well as organic solvents used as raw materials. Technical features and performance: 1. The heating filament is enclosed in a quartz glass tube, eliminating the need for an open flame; this makes it safe, reliable, and has a long service life. 2. The heating electric furnace can be adjusted up and down via a knob, allowing for easy adjustment of the optimal position of the distillation flask. 3. The power of the heating electric furnace can be adjusted continuously and steplessly from low to high using the control panel’s knobs, and it is displayed on the meter. Technical parameters: Electric furnace heating power: 1000W ； Power supply: AC 220V±10%, 50Hz ； Electric furnace movable plate: made of silicon carbide plates, with pore diameters of φ38 and φ50 respectively. Distillation flask: Made of hard glass, with a spherical outer diameter of φ65. Measuring cylinder: 100 milliliters, with a graduation of 1 milliliter. Condenser tube: Made of φ14 brass tube, with an arc-shaped outlet and an unrolled length of 560mm.
