MPC-102A

Pour/Cloud Point Tester

Series MPC-102

MPC-102 series has been designed for automatic determination of Pour Point (PP) and Cloud Point (CP) with small specimen size and shorter test cycle time while securing better test precision than the conventional manual methods'. PP measurement is made utilizing a new ASTM test method, namely "Air Pressure Method"(*1), which yields eventually no bias against the conventional test method, repeatability/reproducibility of 1°C/2°C and 2-3 times faster determinations. The epoch-making high accuracy justifies PP determination at 1°C intervals, which can help increasing the yields in the process. The CP/PP mode executes a CP determination and then PP determination consecutively, which further improves the test throughput in the lab. In addition to liquid-cooled model MPC-102L, air-cooled model MPC-102A is available. Multiple-tests versions with 6 test heads and 3 test heads are also available for higher volume tests.

*1: ASTM D6749 on "Standard Test Method for Pour Point of Petroleum Products (Automatic Air Pressure Method)" HIGH PRECISION POUR POINT DETERMINATION: The typical repeatability and reproducibility are 1°C and 2°C respectively, when PP is determined at 1°C intervals. (*2) This high precision attributes to the patented Air Pressure method, in which the disturbance to the formation of wax crystal structure through the test process is kept at a minimal and consistent level.

*2: Precision information is for general samples such as diesel fuels, base oils and finished lube oils.

POUR POINT AT 1°C TESTING INTERVALS: With this high precision, PP can be determined at 1°C intervals for more precise process control, and therefore a considerable savings in the process can be realized.

EASY AND QUICK PP/CP DETERMINATION: Just set up a sample, select a test mode and then press the START key. The sample is cooled at the steepest possible rate without affecting the formation/growth of wax crystal, which has been known to be a critical factor for PP/CP determination. The test cycle time is typically 1/3 to 1/2 of that of the conventional tilting method's.(*3)

*3:When a diesel fuel oil with PP of -32.5°C is tested, the Air Pressure method took 45 minutes while the conventional tilting method took 140 minutes. Note that the Japan Industrial Standard defines PP in 2.5°C increments

EASY SAMPLE HANDLING: Since the required sample volume is a mere 4.5mL and the sample cup is a test-tube type removable jar, the sample handling is extremely easy.

COMPACT DESIGN &ENERGY EFFICIENT: Use of Peltier Cells for sample cooling/heating made this "mini" tester not only compact in design but energy efficient. Depending on the temperature range, either air, tap water or small chiller with anti-freeze suffices the cooling requirement. No methanol is required.
