SH420 Graphite Digester adopts advanced high-temperature infrared radiation heating technology and microprocessor control platform for accurate temperature control and quick temperature rise.
It has two kinds of temperature rise mode: linear and curve temperature rise mode
It’s offers 20 digestion programs for control of temperature rise curves.
Our optional neutralization system has many functions such as triple filtration, condensate recovery of exhaust gas filtration.
The instrument is build with high-quality anticorrosive pumps, running at low noise.
At the end of the process the tubes are automatically lifted up and the system goes in coolingdown program
This instrument is the perfect choice for small to medium quantity of samples.
Characteristics
20 positions graphite block, have longer life after special anti-oxidation and corrosion resistant processing.
It use advanced insulation technology is eco-friendly designed to reduce energy for warm up.
Advanced PID temperature control technologygive a high accuracy heating up procedure, up to 400ºC in less than 25 minutes.
Temperature control model:
Program control, curve and linear temperature rise.
Multi-protection, over-current protection, high temperature warning, overload protection.
Control display:
5.7” color screen, easy for use.
The SH420 can pretreat for microwave digestion or remove acid after digestion.
The standard configuration comes with waste gas collection hood.
SH420 Hot Block and Graphite digester
WD03 Option module for waste gas collection
- Using PFA sealing cap, longer life
- Clip-on sealing cap, easy for changing
- Specialized water jet vacuum pump is used for vacuum.
- Drip tray design, reduce corrosion damage from acid solutions
SH402 Exhausting gas absorption option
- Absorption device area is translucence design, easy for inspection and changing.
- Suction pressure is adjustable when become negative, to avoid acid gas spilling or emptying.
- Anticorrosion vacuum pump, low noise, large suction tube, reduce wasted gas exhausting and is environmental friendly.
- Ternary filtration system (water condensation, alkali neutralization and active carbon filtration) Ensure perfect neutralization and absorption performance.
- Full PTFE anticorrosion pipe design
