JS94J2 Micro Electrophoresis Instrument Introduction: The instrument can be used to measure the solid-liquid interface electrical properties (zeta potential) of particles in dispersion systems, and it can also be used to measure the interface electrical properties of emulsion droplets. It can also be used to measure the isoelectric point and study the mechanism of the interface reaction process. Obtaining the isoelectric point by measuring the Zeta potential of the particle is an important method for understanding the electrical properties of the particle surface, and it is also an important means in the surface treatment of the particle. JS94 series microelectrophoresis instrument (Zeta potential instrument) adopts microelectrophoresis method, what you see is what you get, and it is more accurate to measure Zeta potential. It can be widely used in cosmetics, mineral processing, papermaking, medical and health care, building materials, ultra-fine materials, environmental protection, marine chemistry and other industries. It is also one of the important teaching instruments for chemistry, chemical industry, medicine, building materials and other majors. Features 1. The instrument adopts a newly designed and simple electric pool, using a 0.5cm thick glass cup, and the electrode is built in the pool. The electrophoresis cup and the built-in electrodes undergo precise microfluidic field calculation and surface treatment to form a set of electrophoresis devices that are completely different from traditional electrophoresis pools. The sample dosage is very small, only 0.5ml each time, easy to clean, easy to use, economical and practical. 2. A well-designed electrode holder is used, which is closely matched with the electrophoresis cup to form a cup-shaped open electrophoresis device. The electrodes are made of silver, platinum and titanium wires, and the working state is stable after surface treatment. 3. The well-made rice mark is placed in the electrophoresis cup and placed on the three-dimensional platform. After adjusting the three-dimensional platform, the clear rice image can be found on the computer screen, and the measurement position can be found. There is no static layer problem. 4. The electrophoresis instrument adopts a semiconductor light-emitting near-field optical system, with a power of only tens of microwatts, which will not affect the measurement environment and measurement accuracy due to heat. The optical system is adjusted, the magnification is increased, and blue light with a shorter wavelength is used. and green light, so smaller particles can be seen. 5. The use of constant voltage low frequency conversion power supply can prevent polarization and at the same time greatly improve the measurement speed. The positive and negative commutation time is continuously adjustable from 0.30 seconds to 1.20 seconds, and the sampling time is only 3 to 10 seconds. The voltage between electrodes can be adjusted as required. 6. The temperature sampling probe is used to automatically and continuously sample the ambient temperature, return to the computer, and automatically adjust the parameters to calculate the Zeta potential. Using computer multimedia technology, under a given rhythm, the ultra-fine particles magnified by 1200 times are automatically continuously "photographed", and a total of four grayscale images in two directions are provided for analysis and calculation. Technical parameter: 1. Using microelectrophoresis, in line with GB/T 32668-2016 "zeta potential analysis of colloidal particles - General rules for electrophoresis" 2. Power consumption: <150W Power input voltage: 220V 50Hz 3. Applicable environment: shockproof platform Applicable temperature range: room temperature to 35 ℃, reading accuracy 0.1 4. Measurement accuracy: the system error is within 5% 5. It is suitable for dispersion system of 0.1~10μm (both aqueous system and organic system can be measured) 6. pH range: generally used in the range of 2.0 to 12.0, and can also be used in the range of 1.6 to 13.0 7. Resolution 12pixel/μm, Japan WDK high power microscope optical system, working distance 7mm 8. Cup-shaped open electrophoresis device with special electrode holder 9. It can measure zeta potential and isoelectric point of dispersion system
