RPVOT (RBOT) Oxidation Test Apparatus

The RPVOT (RBOT) procedure employs severe oxidation conditions to rapidly determine oxidation stability. Suitable for both new and in-service oils, the RPVOT (RBOT) method is applicable to many types of petroleum oils. The sample is oxidized in the presence of water and a copper catalyst in a stainless steel pressure vessel under an initial pressure of 90psi (620kPa). Pressure inside the vessel is recorded electronically or mechanically while the vessel is rotated at 100rpm at constant temperature, and the amount of time required for a specified drop in pressure is the oxidation stability of the sample. A variation of the RPVOT (RBOT) method is the “Thin Film Oxidation Uptake Test” (TFOUT) for gasoline automotive engine oils. 2, 3 and 4-unit systems Oxidata® Pressure Measurement System Conforms to ASTM D2112, D2272 and IP 229 specifications for RPVOT (RBOT) testing Conforms to ASTM D4742 specifications for TFOUT testing Conforms to the specifications of: ASTM D2112, D2272, D4742; IP 229 Capacity: 2, 3 or 4 oxidation pressure vessels Temperature Control: Maximum Temperature: 200°C (392°F) Control Stability: ±0.02°C (±0.04°F) Heater Range: 2 and 3-pressure vessel models: 0-2750W 4-pressure vessel models: 0-3750W Recommended Bath Medium: high temperature silicone heat transfer fluid Drive System: 100rpm positive drive transmission powered by a continuous duty 1⁄2hp ball bearing motor with built-in gear reducer Bath Capacity: K70200/K70290 18gal (68L) K70300/ K70390 25gal (95L) K70400/ K70490 32gal (121L) Capacity: K70200/K70290 2 oxidation vessels K70300/ K70390 3 oxidation vessels K70400/ K70490 4 oxidation vessels Maximum Temperature: 200°C (392°F) Control Stability: ±0.02°C (±0.04°F) Heater Range: 2 and 3-pressure vessel models: 0-2750W 4-pressure vessel models: 0-3750W Recommended Bath Medium: high temperature silicone heat transfer fluid Drive System: 100rpm positive drive transmission powered by a continuous duty 1⁄2hp ball bearing motor with built-in gear reducer Bath Capacity: K70200/K70290 18gal (68L) K70300/ K70390 25gal (95L) K70400/ K70490 32gal (121L) Capacity: K70200/K70290 2 oxidation vessels K70300/ K70390 3 oxidation vessels K70400/ K70490 4 oxidation vessels 2 and 3-pressure vessel models: 0-2750W 4-pressure vessel models: 0-3750W Recommended Bath Medium: high temperature silicone heat transfer fluid Drive System: 100rpm positive drive transmission powered by a continuous duty 1⁄2hp ball bearing motor with built-in gear reducer Bath Capacity: K70200/K70290 18gal (68L) K70300/ K70390 25gal (95L) K70400/ K70490 32gal (121L) Capacity: K70200/K70290 2 oxidation vessels K70300/ K70390 3 oxidation vessels K70400/ K70490 4 oxidation vessels K70200/K70290 18gal (68L) K70300/ K70390 25gal (95L) K70400/ K70490 32gal (121L) Capacity:
