Instrument Introduction

For samples that are relatively easy to digest, a graphite digester can be used for digestion. The graphite digester is used to digest samples under normal pressure, which is simple, easy to operate, and has a large sample processing capacity. It can also be paired with a microwave digestion instrument for primary digestion or acid treatment after digestion.

DRThe series of graphite digesters adopts advanced technology and integrated design, which has the advantages of fast, efficient, energy-saving, and convenient digestion. They have been successfully used for sample pretreatment in industries such as environmental protection, chemical industry, food, medicine, and biochemistry. They can also be used for microwave digestion pretreatment and acid removal treatment. They are atomic absorption, atomic fluorescenceICP-AESIdeal matching products for analytical instruments. The size of the digestion hole can be customized according to customer requirements.

Instrument characteristics

Ø Heating evenly The heating element is made of high-temperature resistant graphite with excellent thermal conductivity, which can ensure temperature uniformity between each digestion hole, and the temperature difference between samples is less than ±2.0 ℃When dissolving multiple samples simultaneously, it can ensure the same reaction temperature and conditions for each sample for batch processing, overcoming various shortcomings of traditional flat electric heating plates.

Ø corrosion preventive The surface of graphite is coated with Teflon, which is easy to clean and corrosion-resistant. It can be used with confidence in corrosive environments such as strong acids and alkalis.

Ø Accurate control PIDThe temperature control system is easy to operate, has excellent performance, and is durable. High temperature control accuracy, up to ±1.0℃The heating rate can be adjusted to achieve programmed heating and control the heating holding time. After completing the heating program, the heating will automatically stop.

Ø Efficient Can perform up to54Simultaneous processing of individual samples greatly improves work efficiency.

Ø A wide range of applications Can be used for routine heating reactions in the laboratory; Accurate control of sample digestion; It can quickly remove acid from the sample after microwave digestion, and directly adjust the volume without transfer.
