Graphite Digestion Instrument

I. Instrument Overview

The graphite digestion instrument uses high-quality high-purity graphite combined with precise surround three-dimensional heating technology, ensuring a very small temperature difference between digestion holes and effectively guaranteeing the parallelism and accuracy of batch sample processing. The intelligent PID temperature-control system supports high-precision programmed heating; users can flexibly set and store multiple digestion programs, making operation simple with excellent reproducibility. Meanwhile, the instrument has multiple safety mechanisms such as over-temperature protection and leakage protection; together with a corrosion-resistant design and a friendly operation interface, it safeguards experimental safety while improving experimental efficiency.

This graphite digestion instrument is an ideal replacement for traditional electric hot plates and electric furnaces. It also adopts a classic 30 mm aperture design, perfectly compatible with mainstream 50 mL and 100 mL digestion tubes on the market — a trustworthy laboratory assistant.

II. Applications

As an efficient laboratory sample pre-treatment platform, the graphite digestion instrument is widely used in environmental monitoring (digestion of heavy metals in soil, sewage and solid waste), food and agricultural product testing (analysis of trace elements in grain and meat), agricultural geology (analysis of fertilizer, feed and rock composition), as well as product quality control and scientific research and teaching. It is an ideal tool for wet digestion and hot extraction in various laboratories.

III. Instrument Characteristics

A 5-inch color touchscreen with an Android operating system is used to operate the instrument — convenient and fast.

It adopts PID temperature-control technology with high temperature-control accuracy and fast heating.

Segmented temperature-control settings: both single-segment and multi-segment heating are available, with flexible settings, and the instrument completes them automatically in sequence.

It uses a high-quality graphite furnace core with a small average temperature difference, good consistency of sample results and higher heat-conduction efficiency.
