Don't struggle to perform the measurement of total concentration of organic nitrogen and ammonia and other analytes. Environmental Express's HotBlock 450 system has a controller that is programmed to ramp the temperature of the block to 160°C and hold that temperature for 60 minutes.  Then the block temperature automatically ramps to 380°C over the course of 60 minutes and holds that temperature for an additional 30 minutes.

Temperature, ramp rate, and hold times are easily programmed for other procedures.  Up to 8 methods with 20 steps each can be stored in the Touch Screen Controller. 

To withstand the highly corrosive nature of these procedures, the high-temperature block is encased in 316 stainless steel.  The controller is independent from the block and should be placed outside of the fume hood to reduce exposure to acid fumes. 

HotBlock 450 units come in multiple configurations 28, 40, and 54 wells.  The HotBlock 450 F models accommodate 100mL flat bottom tubes, including threaded tubes which are compatible with the SimpleDist System.  The HotBlock 450 R models accommodate round bottom tubes in 75, 100, and 250mL volumes. Choose between two controller options the base controller for basic operation or the advanced touch-screen controller
