Lawler offers a wide range of heated baths for the oxidation of oil products by ASTM D4636, D5968, and D6594 methods.
Model HT-10-6 has 6 heated tube positions conforming to ASTM D4636 and related test methods. Each heated tube is of proper dimension to snugly fit the test tube. Each test position is individually temperature controlled with an indicating digital PID controller. Temperature stability of each position is ±0.5°C. Temperature range is from +50° to +360°C. Each tube’s temperature may be independently adjusted so as to assure each sample temperature in each test position is identical. Model HT-10-6 has further flexibility allowing each test position to be at widely different temperatures. Each position is protected against overheating in the event of primary controller failure.
Each position has a float in tube flowmeter with a precision control valve for the delivering 10 ±1 L/hr. or 5 ±0.5 L/hr of air to the test sample.
Model 426-4 is a dry block bath with two independent, insulated aluminum blocks conforming to ASTM D4636 and FTM 719-5307 Corrosiveness and Oxidation Stability of Aircraft Turbine Engine Lubricants, Hydraulic Oils, and Highly Refined Oils. The bench top cabinet holds both blocks separated by insulation. Each block has an independent digital display PID temperature controller. Each block may be operated at a different temperature from the other. Temperature stability and position to position uniformity within each block is ±0.5ºC (or better).
A redundant controller is also provided for each block interrupting power to the heaters in the event of primary controller failure and over heating.
Each position has front a mounted a ball-in-tube flowmeter with capacity of 10 ±1 L/hr of air flow with precision control valves. Condenser cooling water connections are provided at the back panel as well as support for the glassware.
Model 426-6 is a bench model with a solid aluminum block bath with 6 test positions conforming to ASTM D4636 test method. The single digital controller provides sample temperature control of ±0.5°C. Temperature range is from +50° to +360°C.
Each position has a float in tube flowmeter with a precision control valve for the delivering 10 ±1 L/hr. or 5 ±0.5 L/hr of air to the test sample.
Model 426-2+2 is similar to Model 426-4. One block with 2 test positions for FTM 719-5308 and a second independent block with 2 test positions for FTM 719-5307 (ASTM D4636). A pair of flowmeters is for 3 to 5 ±0.5L/hr of air flow. The second pair of flowmeters is for 10 ±1 L/hr.
Model 26 removes moisture from pressurized house air and is equipped with an electronic sensor measuring the dew point. The standard procedure of ASTM D4636 test method specifies that dry air with a dew point of -68°C be used for testing.
Model 33 humidifies air to 10 ±1 mg/L of air and is equipped with an electronic sensor measuring water content. Alternative Procedures 1 and 2 of ASTM D4636 test method may specify that humidified air be used for testing.
