EH-Series Anti-Corrosion Graphite Digestion System is a sample-pretreatment instrument designed for high-concentration acid-fume environments. It simultaneously handles up to 60 samples, fully meeting the demand for high-throughput digestion. Step-temperature control and automatic sample lifting allow the unit to complete digestion, acid-driving, cooling and other steps unattended, minimizing operator exposure to acid vapors.

Multi-Level Protection – Anti-Corrosion & Durable
Stainless-steel housing with PTFE coating for dual anti-corrosion protection
Graphite block surface reinforced with extra-thick PTFE layer to resist strong acid attack
Capacitive touch keys isolated from acid fumes to prevent corrosion
Double-shell architecture: electric components are sealed in an independent lower chamber, providing heat insulation and acid protection
Wireless Control – Safe & Convenient
EH-Series supports both stand-alone and wireless-control modes.
The Android-based APP enables remote control from a mobile terminal, letting you finish a complete digestion run without opening the fume-hood sash, further protecting operators from high-temperature acid fumes.
Real-time temperature curves on the phone for intuitive progress tracking
Edit/set target temperatures and hold times on the phone
Start or stop digestion remotely
Built-in expert method library; create, edit or store custom methods at any time
Audible beep when the program ends
Uniform Heating – Synchronous Digestion
EH-Series uses a unique uniform heater as the heat source. Samples are heated through isostatic graphite blocks, delivering faster ramp rates, better inter-well temperature uniformity and longer service life.
Automatic Lifting – Sample Protection
Auto-lift for cooling
When the heating program ends, the sample rack rises automatically so samples begin to cool, preventing damage from residual block heat if operators are not present.
Hover-to-near-dry
When digestion is almost finished and sample volume is very low, the lift can raise the tube bottom to an easy-view position for continued heating until near-dry, avoiding sample loss.
Observation through sash
During digestion, simply press the wired switch or tap the APP to raise the rack; users can inspect samples through the closed fume-hood glass without exposure.
