Optional automatic cleaning device for 5 cm burner head (Scraper) PPS spray chamber with mixing wing for aqueous and Spray chamber
Fully computer controlled Total Flow Gas box Gas control
 Computer controlled automated flame ignition  Automatic input of additional gases for organic solvents Safety functions
Automatic shut down of gases if the flame is not detected or in case of a system power failure or as a defined action during a multi routine Graphite furnace technique
Integrated computer-controlled transverse heated Zeeman graphite furnace Graphite tube is transverse heated to provide a constant temperature profile Independent gas controls for the external and internal gas flows around and through the tube allow easy removal of volatile matrixes whilst protecting the tube against interference from outside air during the internal gas stop hence maximizing tube life  The advanced furnace concept, utilising the adaptive sensor-less temperature control and emission independent temperature control ensures constant, precise, reproducible and accurate temperature conditions  Easy change of tubes or electrodes

Integrable high-end furnace camera – to observes the deposition of droplets and the drying phase the graphite tube Analytical programs with up to 20 steps can be set up and all steps are easily programmable Technical Data ZEEnit® series | Update 07/2012 | DoM Analytik Jena AG | Konrad-Zuse-Str. 1 | 07745 Jena/ Germany | | [email protected] Temperature

Conversion Technique - By Jack Carpenter I have never used anything other than Colchicine circulate air around the treated crowns are in my opinion (DMSO has sometimes been used) to effect conversion. The use of DMSO did not seem to cause greater amounts of conversions. I am simply not familiar with the CRITICAL importance as crown rot may occur. Always several other things I have heard
