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.
Flexible Graphite preform Plate (Prefabricated Plate) A flexible graphite preform plate is a graphite preform plate formed by rolling with an expanded graphite worm as base material. It has good conductivity and mechanical properties, strong corrosion resistance, is lightweight, and has a long service life The DOCBOND Flexible Graphite preform plate can be customized according to the size of the client s requirements. The client can produce the graphite bipolar plate of the right size only by molding

Graphite digestion instrument is one of the direct, effective and economical sample pretreatment methods for elemental analysis. The application of new heating technology has the advantages of rapid heating, program control, complete digestion, and temperature equilibrium. Our devices are usually used in sample preparation for atomic absorption, atomic fluorescence, ICP, ICP-MS, polarography, etc. 7 advantages make sample preparation no longer difficult: 1. The fully enclosed design prevents heat loss to a large extent and effectively avoids the intrusion of acid mist; 2. High-quality graphite three-dimensional wrapped heating, samples are heated evenly; 3. Unique spraying process, the coating is uniform, firm, and will not fall off after long-term use; 4. Fast digestion and acid removal, high efficiency, and batch processing of samples; 5. PID digital temperature control system, excellent performance; 6. Easy operation, environmental protection and energy saving, cost saving 7. Split type: The controller can be placed outside the fume hood to reduce acid gas corrosion and have a longer service life.
Acicular roll, alloyed with the nickel, manganese and chromium with a bainitic-acicular-martensitic matrix has a higher UTS, hardness and wear resistance is more than the SGP quality. Semi-continuous carbides maintain the wear resistance, while at the same time exhibiting high strength and resistance to fire-cracks. The extensive heat treatment procedure ensures an acicular matrix. Acicular roll can be produced by static casting (Monoblock) or by using the centrifugal cast (CC) Double-pour method.
