Customized Design of Chemical Lab Furniture as Functions

The laboratory is a space with a certain risk coefficient. The experimental operation uses some reagents such as acid, alkali and organic solvent.Test tube, flask, beaker, condenser and other glassware;Precision instruments such as atomic absorption, gas chromatography, liquid chromatography, ultraviolet spectrophotometer, and high temperature equipment such as ovens and muffle ovens.Laboratory planning and design must take “practicality and safety” as the starting point, comprehensively consider the safe operation requirements of various instruments and equipment, and configure the corresponding experimental equipment. Meanwhile,the lab should be equipped with chemical lab furniture to ensure the normal running with high efficiency.

⑴ General and analytical chemistry laboratory.

Ordinary and analytical chemical laboratory is engaged in the research including chemicals of mixing, heating, cooling, distillation, evaporation, dilution and reaction, this work can be in open laboratory bench or smoke ark operation, the required analysis equipment such as spectrophotometer, liquid chromatography, gas meter, etc., often some harmful substances are used in analytical chemistry laboratory, including the highly toxic, volatile liquid, powder, combustible gas pressure.Although the analysis process of toxic substances can be broken down into non-toxic compounds, they are still toxic in the analytical operation. It is generally not recommended that analytical chemistry laboratories handle extremely toxic chemicals, such as carcinogenic, lethal and explosive chemicals, and highly radioactive substances.

Necessary Chemical lab bench: side table, central bench (sink, reagent rack), fume hood, medicine storage cabinet, utensils storage cabinet, reflux condensing device (small cup sink and water cock), pumping filter device (pumping filter faucet, small cup sink).

(2) Organic Chemistry Laboratory

Organic chemistry laboratory is engaged in the research including general organic analysis, quantitative analysis and qualitative analysis, drug testing (content determination and identification, determination of pesticide residues (666 DDT pesticide residues, chrysanthemum fat pesticide residues, organic nitrogen, organophosphorus pesticide residues of pesticide residue and gas analysis (artificial coal gas composition analysis, the composition of natural gas, liquefied petroleum gas component analysis), determination of hazardous substances (benzene and pyrazole, polycyclic aromatic hydrocarbons, aflatoxin), infrared spectrum unknown material identification samples of unknown material identification, detection, mass spectrometry (such as water, food, blood).The organic laboratory has high performance liquid chromatograph, gas chromatograph, thin layer scanner, element analyzer, nuclear magnetic resonance instrument, infrared absorption spectrometer and other large instruments and supporting facilities.

Required laboratory furniture etc: side table, central table, fume hood with central station,storage cabinet, reflux condensing device (small cup sink and water cock), pumping filter device (pumping filter faucet, small cup sink)..

(3) Inorganic Chemistry Laboratory

Inorganic chemistry laboratory is engaged in the research including heavy metals (lead, cadmium, mercury, arsenic, etc.) quantitative analysis, including the environment, food, biological samples, such as various types of TCM, common qualitative and quantitative analysis of trace metals, such as Fe, Cu, Ca, K, Mg, Mn, zinc, Li, Mo, Sr, Co, etc, trace elements of precious metals (Au, Ag, Pt) and trace metal elements (such as: Tl), nonmetal and its compounds (such as:Se, B, P, N, NO2 -, NO3 -, F -, Cl -, SO42 -, etc.), capacity analysis of the content of various projects, medicines and proprietary Chinese medicine drugs, food nutrition analysis (such as: carbohydrates, starch, fat, cellulose, etc.), physical index analysis (such as density, melting point, refractive index, optical rotation, PH, moisture, etc.), inorganic chemical analysis of various physical and chemical indicators.Inorganic laboratory has atomic absorption spectrometers, ultraviolet spectrometers, fluorescence spectrometers, inductively coupled plasma atomic emission spectrometers, ion spectrometers and other large imported precision instruments, can undertake the majority of inorganic project analysis and testing work.

Required chemical lab bench etc: wall bench, central bench (sink, reagent rack), fume hood, medicine&utensils storage cabinet, pumping filter device (pumping filter faucet, small cup sink).
