Meicheng DR series high-pressure graphite digester

Application fields:

Meicheng DR series high-pressure graphite digesterNot only can it be used for sample pretreatment experiments, but it can also be used for sample pretreatment preparation and acid removal before microwave digestion experiments. It is an atomic absorption, atomic fluorescenceICP-AESIdeal matching products for analytical instruments.

Instrument features:

1) Uniform heating: High pressure graphite digesterThe heating element is made of high-temperature resistant graphite material with better thermal conductivity, effectively ensuring temperature uniformity between the digestion holes (temperature difference between samples ＜ ±)2.0 At a temperature of (℃), when digesting multiple samples in batches, it can effectively ensure that each sample is uniformly heated, resulting in better sample digestion effect.

2) Corrosion resistance:The use of special PTFE coating on the surface of graphite can not only effectively improve the corrosion resistance of the product in harsh environments such as strong acids and alkalis, but also make the digestion instrument easier to clean and maintain after the experiment.

3) Accurate control:usedPIDThe temperature control system has the advantages of easy operation, superior performance, durability (all temperature control systems have undergone moisture-proof, anti mold, and anti salt spray treatment processes), and high temperature control accuracy (accuracy: ±)1.0Characteristics such as temperature (℃). Not only can it adjust the heating rate, achieve programmed heating, and control the heating holding time, but it can also automatically stop heating after completing the heating program.

4) Efficient work:DRThe maximum number of models that can accommodate samples simultaneously in the series of graphite digesters is:DR-77, available for77Conduct experiments simultaneously with each digestion tube.

5) Scope of use: Meicheng DR series high-pressure graphite digesterNot only can it be used for routine heating reaction experiments in the laboratory; It can also accurately control the independent conduct and completion of sample digestion experiments; And before the microwave digestion experiment, pre-treatment experiments can be completed for the sample, and after the microwave digestion experiment, experiments such as rapid acid washing and constant volume can be carried out for the sample. This not only effectively avoids the occurrence of secondary contamination of the sample caused by changing the sample container, but also effectively avoids the occurrence of incomplete acid washing or reflux caused by condensation due to uneven temperature of the sample during the acid washing experiment.

6) The high-pressure graphite digester can be equipped with a dedicated high-pressure digestion tank:Double layer sealed structure design, pressure resistant10MPaMeet the national pressure vessel standards; Effectively ensuring that volatile substances are not lost during the sample preparation process, overcoming the shortcomings of traditional ashing methods for sample preparation.
