   Ashing       Ashing is also referred to as charring; this is the step in a graphite furnace AA program that is designed to remove matrix constituents that might interfere with the measurement of the analyte. Ashing temperatures vary from 200º to 1800° C, depending on the matrix and analyte element. 
   Box       Box furnaces are convenient furnaces to use. As the name implies, the furnace has a box shape and a box-shaped interior. The interior dimensions (10 to 50 cm per side) are much larger than a tube furnace, but the unit is often compact enough to sit on a benchtop. A door on the side permits quick and easy access to the interior. Several examples of box furnaces and their controllers are shown below. 
   Bottom Loading       Bottom loading furnaces load the sample or product to be treated through the bottom of the chamber via a platform elevator. 
   Top Loading       The product to be processed is loaded from the top. 
   Tube       A tube furnace is designed to heat a tube that is usually 50 to 100 cm in length and from 25 to 100 mm in diameter. Samples are placed inside the tube in ceramic or metal boats using a long push rod. The tube is surrounded by heating elements, which may also incorporate a thermocouple (a thermocouple can also be inserted down the tube if desired). 
   Other       Other unlisted, specialized, or proprietary configuration.

Specifications
   Process Temperature       Maximum temperature at which the unit may operate and still maintain rated performances. 
   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.
   Width / Tube O.D.       The internal width dimension of the unit, or for tube furnaces, the outer diameter of the tube. 
   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.
   Length (Chamber / Tube)       The length dimension of the unit, or on tube furnaces, the heated length. 
   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.
   Height       The internal height dimension of the unit. 
   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.

Tube Furnace Features
   Tube Furnace Features       
   Your choices are...         
   Hinged       A tubular furnace that is hinged on its longitudinal axis for easy access. 
   Three Zone / Multi-Zone       A three zone or multi-zone furnace has the ability to ramp up to a specified temperature and maintain that temperature for a set time and then ramp up to a secondary higher temperature and maintain that temperature for a set time. 
   Rotary       These types of furnaces contain a rotating refractory cylinder to rotate the product under test in a cylindrical container enabling thorough mixing with air. 
   Horizontal       The tube is configured horizontally in the furnace. 
   Vertical       The tube is configured vertically in the furnace. 
   Thermocouple Calibration       A specialized tube furnace that normally has a modified control system with a special readout, frequently uses components calibrated to national standards, and often incorporates a centralized equaling block and end plugs to accommodate the thermocouples. 
   Other       Other unlisted tube furnace feature. 
   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.

Atmosphere & Control
   Atmosphere       
   Your choices are...         
   Air / Oxidizing       Furnace or thermal processing system employing an air or oxidizing atmosphere. 
   Inert       Furnace or thermal processing system employing an inert gas such as argon as an atmosphere or shielding blanket. 
   Reducing       Furnace or thermal processing system employing a reducing gas such as hydrogen as an atmosphere. 
   Vacuum       Normally when the word vacuum is used it refers to any absolute pressure below that of normal atmospheric pressure. Atmospheric pressure is defined as 14.6 psia or 760 torr, any pressure less than this is considered a vacuum. In a vacuum furnace, the heat-treating process takes place inside a vessel that is airtight. This allows a vacuum to be drawn inside the vessel. The entire heat-treating process can take place under vacuum or precisely controlled atmospheres can be introduced. Heat treating under vacuum can: prevent surface reactions, such as oxidation or decarburization; remove surface contaminants such as oxide films and residual traces of lubricants; add a substance to the surface layers of the work; remove dissolved contaminating substances from metals by means of degassing. 
   Other       Other unlisted or specialized atmosphere 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.
   Controller Type:      Ovens may have either a single set point or a programmable controller to adjust temperature and temperature stability.
   Your choices are...         
   Single Set Point       Furnace has a specific temperature point to reach upon activation. 
   Programmable       Furnace may be programmed to reach different temperatures at different time intervals. 
   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.
   Over-Temperature Protection?       The furnace comes with controls to provide over temperature protection for the furnace and product against temperatures exceeding specified values. 
   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?       The furnace is equipped with a computer interface for programming and control. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Application Software?       The furnace comes with application software for control and programming.
