Liquid Temperature Control in Petrochemical Testing
Petrochemical testing involves analyzing various properties of crude oil, petroleum products, and related substances. Many of these testing methods require precise temperature control to maintain specific conditions or simulate real-world scenarios. Fluctuations in temperature can significantly impact the test results, leading to inaccuracies and potential safety concerns.
Oxidation Stability Testing
Oxidation stability tests, such as ASTM D2440 (Mineral Oil Oxidation Stability), ASTM D943 (Oxidation Characteristics of Inhibited Mineral Oils), and ASTM D4310 (Oxidation Stability of Lubricating Greases), require precise temperature control to evaluate the resistance of petroleum products to oxidation under elevated temperatures. JULABO’s Precision Series liquid immersion equipment, like the CORIO CP-600F for ASTM D2440 and the CORIO CP-300F for ASTM D943 and D4310, provides accurate temperature control and stability for these tests.

Corrosion tests, including ASTM D130 (Copper Strip Corrosion), ASTM D4048 (Copper Strip Corrosion for Lubricating Greases), and IP 227 (Silver Strip Corrosion), assess the corrosive properties of petroleum products on metallic surfaces. The CORIO CP-600F from JULABO offers precise temperature control for these tests, ensuring consistent and reliable corrosion evaluation.
Fuel Oxidation Stability Testing
Tests like ASTM D525 (Oxidation Stability of Gasoline) and ASTM D873 (Oxidation Stability of Aviation Fuels) determine the oxidation stability of fuels under controlled temperature conditions. The CORIO CP-600F and CORIO CD-600F from JULABO provide accurate temperature control for these tests, simulating real-world conditions and enabling reliable assessment of fuel stability.
Grease Oxidation Stability Testing
ASTM D942 (Oxidation Stability of Lubricating Greases) evaluates the resistance of greases to oxidation at elevated temperatures. Again, JULABO’s CORIO CP-600F offers precise temperature control for this test, ensuring accurate measurement of grease oxidation stability.
Density and Relative Density Testing
Tests like ASTM D1298 (Density, Relative Density, or API Gravity of Crude Petroleum and Liquid Petroleum Products by Hydrometer Method) and related standards require precise temperature control for accurate density measurements. JULABO’s CORIO CP-600F or CORIO CP-300F circulators provide stable temperature control for these tests, ensuring reliable density and relative density determinations.
Liquid Petroleum Gas (LPG) Corrosion Testing
ASTM D1838 (Copper Strip Corrosion by Liquefied Petroleum Gases) and ISO 6251 (Corrosion of copper and copper alloys by liquefied petroleum gases) assess the corrosive effects of LPG on copper surfaces. The PURA series of water baths from JULABO offers precise temperature control for these tests, enabling accurate evaluation of LPG corrosion.
In addition to the PURA series, JULABO offers a wide range of circulators and temperature control systems suitable for various petrochemical testing applications. For example, the DYNEO DD-449F and MAGIO MS-310F circulators can be used for temperature control in gas chromatography (GC) and mass spectrometry (MS) systems, which are essential analytical techniques in the petrochemical industry.
