Ji'nan Heng Technology Company Limited is a company specializing in chemical reagents, pharmaceutical intermediates and precision instrument R & D, production, sales in one of the high-tech enterprises. The company has a team of more than a professor (Part-time), Ph.D., senior engineer for the main R & D, production and sales teams, and in close cooperation with the Shanghai Institute of organic chemistry, Shandong University, Shandong Normal University and other units. Now the company is divided into three departments: fine chemical reagent and instrument sales department, pharmaceutical intermediates, import and export trade, R & D and production of
(a) precision chemical reagent (main import type, please chemical reagent catalog reference to the company's website and the new reagent series). The main agent Alfa, Avocado, Aldrich, ACROS, Sigma, Fluka, ICN (MP), Lancaster, TCI and other brands; at the same time, according to customer requirements development and synthesis of the specified reagent.
(two) are updated weekly chemical reagent (see updated daily chemical reagent).
(three) and chemical raw materials, pharmaceutical intermediate.
(four): high-grade laboratory instruments and hydrothermal reaction kettle (to ensure that the temperature of 250 degrees), rotary evaporator, low temperature cooling circulating pump, precision electronic balance, micro melting point apparatus, agitator, pH meter, ice machine, electric heating sleeve..., is absolutely the most affordable price and the integrity of the after sale service (can be discussed the special operating mode).
(five) and chemical properties testing. For example: crystal structure (for analysis), biological macromolecular structure testing, magnetic susceptibility, magnetic resonance spectroscopy, X- - ray powder diffraction, scanning electron microscopy and NMR, differential thermal analysis...... And the absolute lowest price and most reliable data.
in addition, our company can free help customers on the crystal structure data analysis (keyword: X- ray diffraction, crystal structure data analysis, SHEXL-97).
(six) other do everything in one's power to help
