Configuration




   Digestion Type:       
   Your choices are...
 
      
 
   Acid Digestion
 
     In acid digestion the sample is digested under elevated pressure (100-500 psi) and temperature (50-180 degrees C) conditions using conventional acids, such as nitric and hydrochloric acids.
 
   Microwave Digestion
 
     Microwave energy heats microwave-absorbing reagents containing a sample inside a pressurized, microwave-transparent container. Pressurization allows higher temperatures to be achieved, thus increasing the speed of digestion. Pressure and temperature inside the control vessels may be monitored and used to determine the amount of microwave energy applied.
 
   Other
 
     Other unlisted or proprietary method.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Reaction Type:       
   Your choices are...
 
      
 
   Open Flask
 
     The reaction takes place in an open container.  Open vessel digestion is classically the most commonly used method.
 
   Closed Flask
 
     The reaction takes place in a closed container.  The elevated pressures that can be achieved in closed reaction vessels decrease digestion time.
 
   Search Logic:      Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Performance Specifications




   Temperature Range:
 
     The temperature range of the reaction.
 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Pressure Range:
 
     The pressure range that the digester can withstand.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Number of Samples:
 
     The number of samples the digester can process.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Sample Volume:
 
     The volume of sample the digester can accommodate.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Digestion Time:
 
     The amount of time required to completely digest the sample.
 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
User Interface Options




   Local Interface:       
   Your choices are...
 
      
 
   Analog Front Panel
 
     The panel has analog user inputs such as potentiometers, dials, switches, for adjustment of output, ranges, etc.
 
   Digital Front Panel
 
     The panel uses digital keypads or menus for programming.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Computer Interface?
 
     Can be controlled or monitored remotely with a computer via interface.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Computer Interface Options:       
   Your choices are...
 
      
 
   Serial Interface
 
     A port, or interface, that can be used for serial communication, in which only one bit is transferred at a time. Examples include RS232, RS422, RS485, USB etc.
 
   Parallel Interface
 
     A channel capable of transferring more than one bit simultaneously. Examples include PC Printer Port, Centronics etc.
 
   Other Computer Interface
 
     Modem, transmitter, TTL, etc.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Application Software Included?
 
     For control or for monitoring the process.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Display Type:       
   Your choices are...
 
      
 
   Analog Meter
 
     The unit has an analog display such as a dial or indicator lights.
 
   Digital Numerical Display
 
     Has display for numerical values
 
   Video Display
 
     CRT, LCD or other multi-line display
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Features




   Programmable?
 
     The device must be programmable, or adjustable, to provide for different ranges, materials, levels, outputs, etc.
