Qingyuan Innovation Laboratory (China Fujian Chemical Engineering Science and Technology Innovation Laboratory) is a national second-class institution, a non-profit provincial scientific research institution with independent legal personality. The laboratory was established in September 2019, led by the Quanzhou Municipal People's Government, relying on the joint construction of Fuzhou University and Sinochem Energy Co., Ltd. (including the subsidiary Sinochem Quanzhou Petrochemical Co., Ltd.). The laboratory adopts "provincial and municipal joint construction, city-based", guided by leading the development of the petrochemical industry, based on gathering high-level talents, and centered on breaking through "stuck neck" technology, forming a leading core technology research and development base , a first-class innovative talent training base, and a supporting high-end business incubation base.

Jiahang's Digipol-D70 automatic density meter adopts the principle of U-tube oscillation method, perfectly combines Peltier precise temperature control technology and high-definition video camera technology, not only provides users with accurate, stable and reliable test results, but also brings users Efficient and convenient testing experience. The high-definition video can easily see whether there are air bubbles in the sample. The pulse excitation and high-precision detection technology are used to facilitate the user to accurately and quickly measure the sample density and density-related parameters. Improve efficiency Innovation points: automation integration, realize one-key measurement function; built-in Peltier temperature control, improve accuracy and stability; high-definition video avoids the influence of air bubbles; data can be directly printed by printer; conforms to 21CFR Part 11, audit trail, pharmacopoeia and Electronic signature.


Shanghai Jiahang Digipol-P series polarimeter is an instrument for measuring the optical rotation of substances. Through the measurement of optical rotation, the specific rotation, international sugar content, concentration and purity of the substance can be analyzed and determined, and it is widely used in medicine, petroleum, food, chemical industry, flavor, fragrance, sugar and other industries and related universities and research institutes Place. Innovation points: Built-in Peltier temperature control, improving accuracy and stability; with optical rotation/specific rotation/concentration/sugar; LED cold light source instead of traditional sodium lamp and halogen tungsten lamp; multi-level authority management, authority can be freely configured ;8-inch touch color screen, user-friendly operation interface; meet the requirements of 21CFR (electronic signature, data traceability, audit trail, data tamper-proof and other functions); fully meet the GLP GMP certification specifications.

DigiPol-R series automatic refractometers are equipped with high-performance linear array CCD photosensitive components, through high-speed, high-precision signal acquisition and analysis and processing technology, equipped with semiconductor Peltier super temperature control system. It can efficiently and accurately measure the refractive index (nD) of transparent, translucent, dark, viscous and other liquids and the mass fraction of sugar solution (Brix). Application fields: Automatic refractometer is widely used in petroleum industry, oil industry, pharmaceutical industry, food industry, daily chemical industry, sugar industry, etc. It is also one of the commonly used equipment in schools and related scientific research units.

JHX-5 Micro Melting Point Apparatus combines high-precision temperature control technology and high-definition optical lens magnification technology, which not only provides users with accurate, stable and reliable test results, but also brings users an efficient and convenient test experience. Optical lens magnification technology can easily and clearly see the whole process of sample melting. Fields of use: Melting point instruments play an important role in the chemical industry and pharmaceutical research, and are used for the production of food, medicine, spices, dyes and other organic crystal substances. Outstanding features: process 3 samples at a time; video clearly shows the melting process of samples; heating rate (0.1-10) ℃/min can be set arbitrarily; fan automatically cools down; capillary heating stage method is dual-purpose.
