Heavy metal digester, SH230N

Heavy metal digester offering fast, efficient digestion, easy handling and a large sample capacity. Used in the food, pharmaceutical, agricultural, forestry, environmental, chemical and biochemical sectors, and by universities and research institutions, to digest soil, feed, food, ore and other samples before chemical analysis; suitable for use with atomic absorption, atomic fluorescence, ICP-AES and other analytical instruments.

• Continuously adjustable heating temperature, held constant at the set point; high heat-transfer efficiency and easy operation
• Teflon coating effectively protects the instrument from corrosion by the acid and acid gas released during digestion
• Deflector tank prevents acid from splashing into the electrical circuits during operation
• Multiple protection of the whole instrument against over-voltage, over-current, overheating and other faults
• Embedded software temperature control: precise, stable and uniform heating with a small average temperature difference across the heating zone, for consistent digestion of all samples
• Intelligent monitoring of the working status of each heating unit and real-time control of the instrument
• Eco-friendly fibre and air-duct thermal insulation for better heat retention
• PTFE (Teflon) and borosilicate glass digestion tubes available
• Three-dimensional surround heating heats all parts of the sample evenly and keeps heat loss to a minimum
• Real-time human–machine interaction; heating output is switched off automatically when the set time has elapsed
• More precise digestion temperature control: upgraded embedded automatic software temperature control and a built-in timer for easy time control; like the other SH series digesters, the instrument is built from materials that combine uniform thermal conductivity with corrosion resistance
• Durable and safe: specially selected PTFE (Teflon) coating with excellent chemical stability, resistance to corrosion, heat, abrasion and moisture, good sealing, non-stick and electrical insulating properties, and ageing resistance; no insulation material is exposed, so acid and acid gas cannot corrode it and impair the insulation
• Configurable for a wide range of applications: PTFE or borosilicate glass digestion tubes can be chosen as the method requires, widening the range of acids that can be used for digestion
