Search By Specification


Configuration
   Degasser Type:       
   Your choices are...
  		      
 
   Flow Degasser
  		     A gentle flow of dry gas over the surface of the particles serves to quickly carry away moisture and other contaminants.  Needle valves allow careful control of flow rate to avoid elutriation (blowing out) of fine powders.
 
   Vacuum Degasser
  		     Water trickles through the degasser where its flow is broken up by a randomly packed medium. This results in a very thin film of water from which gas can easily escape. The vacuum inside the filter increases the rate of gas escape. 
 
   Helium Degasser
  		     In helium degassing, the air dissolved in the solvent is expelled by continuously passing helium through the solvent. This is the most effective method of degassing and is particularly recommended for trace analysis and for avoiding the fluorescence quenching due to the affect of dissolved oxygen on the analytes. The disadvantages associated with helium degassing are the high price of the helium and the fact that the more volatile solvent components like tetrahydrofuran can also be expelled by the helium over a period of time. This can give rise to changes in retention times.
 
   Other
  		     Other unlisted or proprietary degasser type.
 
   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.
   Vacuum Rating:
  		     The vacuum range the degasser operates within.
 
   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.
   Maximum Flow Rate per Channel:
  		     The maximum flow rate through the degasser.
 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Number of Channels:
  		     Number of inlet channels.
 
   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.
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
   Continuous Operation?
  		     The degasser is set up to accept a continuous flow of sample to be degassed.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Zero Baseline Functions?
  		     A "zero baseline" test can be used to study the precision of the degasser.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Error and Leak Checking Functions?
  		     The degasser can monitor itself for leaks and errors.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
Environment
   Operating Temperature:
  		     This is the full required range of ambient operating temperature.
 
   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.
