ICP/ICP-MS graphite digestion apparatus was used for sample pretreatme
Model: XJ
our advantages:
1. Fully enclosed design to prevent heat loss and acid fog intrusion;
2. Three-dimensional wrapping of high-quality graphite is heated, and the sample is heated evenly;
3. High efficiency, sample batch processing;
4.PID digital temperature control system, excellent performance;
5. Split type: Controller can be placed outside the fume hood, reduce acid gas corrosion, longer service life. Hole number :16, 20, 24, 36, 40, 42, 48 bit, can be customized temperature control range: room temperature -220 Temperature control accuracy Temperature difference between holes 1.5 Rated voltage :220V Heating power :2-3KW Continuous working time :48h
Graphite digestion instrument is a heating device specially designed and manufactured for laboratory heating, which can be used for sample heating, cultivation and drying. It adopts international advanced technology and has the advantages of fast, efficient, energy-saving and convenient acid flushing. It uses digital circuit PID to control temperature, which is more accurate. High purity and high quality graphite heating carrier, coated with Teflon coating, has been successfully used for sample pretreatment in environmental protection, chemical industry, food, medicine, biochemistry and other industries. It can also be used for pretreatment of microwave digestion and acid rush treatment. It is an ideal supporting product for atomic absorption, atomic fluorescence, ICP-AES and other analytical instruments.
characteristic
1. Design: generous appearance: simple, upright and generous.
2. Clean and corrosion resistant: the heating body is coated with extra thick PFA, which is corrosion resistant and pollution-free. The unique spraying process is adopted, and the coating is uniform, firm, and will not fall off after long-term use.
3. High efficiency: advanced all-in-one surrounding heating mode is adopted, so that each part of the sample is heated evenly, which greatly prevents heat loss, eliminates the temperature difference between different parts of the same sample, and quickly and thoroughly dries acid.
4. Economical: The surrounding heating process is fast and convenient, which can save 75% of electric energy and has low use cost.
5. Precise temperature control: PID temperature control system, simple and convenient operation, excellent performance, durable. The temperature control accuracy is high, up to and the heating rate is stable.
6. Superior thermal conductivity: a reasonable heating method and a heating body with excellent thermal conductivity can ensure the temperature uniformity between digestion holes. The temperature difference between samples is less than 1.5 (room temperature - 260 ). When several samples are acid treated at the same time, the same reaction temperature and conditions can be guaranteed for each sample for batch processing.
