Cylindrical heating chamber provides excellent radial temperature uniformity.
Koehler K Auto-ignition Apparatus for Petroleum Testing (ASTM E) | Labequip
No condensed phase, liquid or solid, qstm be present when ignition occurs. ASTM Method being used? Looking for a specific close-up?
Pharmaceutical laboratory apparatus stability chambers, tablet disintegration, tablet dissolution, tablet hardness, V-blenders, These temperatures can be expected to vary with the test pressure and oxygen concentration.
Vessel material can also be an important factor. A hinged holder in the cover facilitates handling of the test flask.
See also Appendix X2. Within certain limitations, this test method can also be used to determine the autoignition temperature of solid chemicals which readily melt and vaporize at temperatures below the test temperature and for chemicals that are gaseous at atmospheric pressure and temperature.
Control panel has temperature controls and digital thermocouple readout with four-position selector switch. Adjustable mirror permits safe viewing of xstm flask interior during testing. Oxidation Bomb for Petroleum Testing.
Koehler K47000 Auto-ignition Apparatus for Petroleum Testing
The autoignition temperature by a given method does not necessarily represent the minimum temperature at which a given material will self-ignite in air. Historical Version s – view previous versions of standard.
General Use laboratory apparatus balances, baths, blenders, centrifuges, chart recorders, freezers, fume hoods, furnaces, glassware washers, glove boxes, mixers, moisture testing, ovens, pumps, shakers, vacuum equipment, water purification Product Description The K Autoignition Apparatus determines the lowest temperature at which the vapors of a liquid or solid chemical sample will self-ignite under prescribed laboratory conditions. Available request a quote.
Such materials will thermally degrade in the flask and the accumulated degradation products may ignite. For such materials, ignition is dependent upon the thermal and kinetic properties of the decomposition, the mass of the sample, and the heat transfer characteristics of the system. Thermocouples plug directly into the furnace control unit for quick disconnection when removing the flask.
ASTM E – 14 Standard Test Method for Autoignition Temperature of Liquid Chemicals
Modified crucible furnace with digital thermocouple readout of flask temperature at prescribed points per ASTM specifications. Historical Version s – view previous versions of standard Translated Version s: However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.
Linearized analog output permits connection to a strip chart recorder or datalogging instrument. What are your requirements. Lab Equipment for Sale: Type text as it appears:: Furnace cover has ports for flask exterior thermocouples, and a borosilicate glass thermocouple tube is provided to assure correct positioning of the gas temperature thermocouple inside the test flask.

Test Flask, mL and Thermocouples 4 The following link provides additional information from the instruction manual or original manufacturer’s brochure.
The volume of the vessel used is particularly important since lower autoignition temperatures will be achieved in larger vessels. Responsibility for extension of this test method to solids of unknown thermal stability, boiling point, or degradation characteristics rests with the operator.
