Laboratory Equipment

The lab-scale carrier extruder is a core forming equipment used in catalyst R&D, ceramic materials, and the preparation of novel functional materials. This equipment is primarily used to extrude plastic paste—prepared by mixing powder raw materials with binders, extrusion aids, and solvents—through a specific die under high pressure, continuously forming wet extrudates with fixed cross-sectional shapes (such as cylindrical, trilobal, or quadrilobal) and dimensions. After subsequent drying and ca

The UV-Visible Spectrophotometer is a key analytical instrument used in catalyst preparation for characterizing the chemical state of impregnation solutions. In the preparation of catalysts via the impregnation method, the existing forms (monomeric or polymeric) and redox valence states of active metal components (such as Ni, Co, Mo, W, Cu, Fe, etc.) in the solution directly determine their dispersion on the support surface, the strength of support-active component interactions, and ultimately t

The Hydrogen Generator, also known as a hydrogen production device, is a specialized piece of equipment that converts raw materials (typically water or hydrogen-containing compounds) into high-purity hydrogen gas through electrochemical or physicochemical methods. As the core equipment at the source of the hydrogen energy industrial chain, it is widely used in laboratory analytical instrument gas supply (e.g., GC, GC-MS), catalyst evaluation experiments (e.g., hydrogenation reactions and reducti

The Chemisorption Analyzer, often referred to as a multi-functional catalyst characterization instrument, is a core precision apparatus used in catalytic materials R&D for the quantitative determination of the number of active surface sites on catalysts, metal dispersion, active component particle size, and acidity/basicity. Unlike physisorption (which primarily measures specific surface area and pore size), chemisorption exploits the selective chemical bonding between adsorbate molecules (such

The Sulfur and Nitrogen Analyzer, also known as a Total Sulfur and Total Nitrogen Analyzer, is a precision analytical instrument that combines high-temperature combustion pyrolysis with highly sensitive spectroscopic detection technology. This equipment is specifically designed for the rapid and accurate determination of total sulfur (TS) and total nitrogen (TN) content in liquid, solid, and gas samples. As a key quality control instrument in petrochemicals, environmental monitoring, coal and po

The Sulfidation Furnace (also referred to as a Sulfiding Unit) is a critical piece of specialized equipment in catalyst preparation and evaluation. It is primarily used to convert oxide-form metal precursors (such as MoO₃, WO₃, NiO, CoO, etc.) into highly active sulfided states (such as MoS₂, WS₂, Ni-Mo-S, and Co-Mo-S phases). In the fields of hydrotreating, hydrocracking, and residue hydrotreating catalysts, the effectiveness of the sulfidation process directly determines the catalyst's activit

The Atomic Absorption Spectrophotometer (AAS) is a precision analytical instrument used for the quantitative determination of metal and metalloid elements in samples, based on the principle that ground-state atoms absorb light at characteristic wavelengths. Since its introduction in the 1950s, it has become the "gold standard" for trace and ultra-trace metal analysis in fields such as environmental monitoring, food safety, pharmaceutical and healthcare, geology and mining, petrochemicals, and ma

The Nitrogen Adsorption-Desorption Analyzer, also known as a Specific Surface Area and Pore Size Analyzer, is a core characterization instrument used in materials science for the precise determination of surface characteristics and pore structures of solid porous materials. Based on the principle of gas physisorption, this instrument uses nitrogen at liquid nitrogen temperature (77K) as the probe molecule. By measuring the amount of gas adsorbed and desorbed at different relative pressures, it g

The Carbon Residue Analyzer is a specialized analytical instrument used in the petrochemical industry for determining the carbon residue content of oil products—the residue formed after evaporation and cracking under specific high-temperature conditions. The carbon residue value is a key indicator for evaluating the coking tendency, thermal stability, and combustion performance of oil products, particularly heavy oils, residual oils, lubricating base oils, and biodiesel. This data is of decisive

For viscosity testing of feedstocks (such as crude oil and heavy residual oil) as well as finished petroleum products (such as diesel, lubricating oil, and fuel oil), a professional viscometer must be used. This is one of the most essential physical property tests in petroleum product quality inspection, trade settlement, and process control.
