Laboratory Preparation Plan
Daily analytical materials of the laboratory include carbon steel, low alloy steel, alloy steel, stainless steel, cast iron, ductile iron, non-ferrous metals, etc. The main elements analyzed are C, S, Si, Mn, P, Cr, Ni, Mo, Cu, Fe, V, Ti, Re, Mg, and others.
First, General Conditions of the Laboratory :
1. Determination of laboratory location:
The laboratory should be located in a factory away from main roads and large seismic sources, and far from workshops with significant smoke and dust emissions.
2. Overall design of the laboratory:
Based on the characteristics of the materials and elements, each sub-chamber is set up, arranged scientifically, and equipped with power lines, water pipes, and sewage systems. Proper lighting, natural ventilation, and illumination are also considered.
3. Laboratory power equipment:
The wire diameter for the power supply should be determined based on the total power of the equipment. The laboratory should have a dedicated power line and proper grounding to ensure safety.
4. Laboratory safety measures:
Most chemicals used in the lab are toxic or corrosive, some are flammable or explosive. It is essential to classify and store them properly. Qualified labs should have designated storage rooms for chemicals and fire prevention facilities.

• External sample handling, easy to operate, no valve or pipe aging;
• Different cold light sources allow expansion of measurement element ranges;
• Detection process: Sampling → Weighing → Chemical processing → Curve comparison → Data display and print.
Third, Auxiliary Equipment
1. TG328A mechanical analytical balance (1200 yuan, 0.1mg precision) or Shanghai Yueping electronic balance (4500 yuan, 0.1mg precision);
2. Distilled water system (5 liters/hour) or 10 kg of distilled water (usually not required by customers);
3. Glassware and chemical reagents (purchased by customer or company, around 1200 yuan for manganese, phosphorus, and silicon);
4. Standards (purchased by customer or company, 90 yuan/bottle);
5. Drill, oxygen (supplied by customer).
Fourth, Detoxification Equipment (Exhaust Facilities)
One fume hood (customer purchase).
Fifth, Workbench
Customers can purchase reagent racks for the workbench, making it easy to access items like pipettes and test tubes. The bench should be placed away from instruments, close to the sink for reagent preparation and chemical operations. Other parts can accommodate the main instruments such as balances and analyzers. The carbon-sulfur analyzer is typically placed near the oxygen cylinder, while the balance and other analyzers are placed at corners. Ensure adequate spacing between major instruments to avoid interference from reagents and temperature/voltage fluctuations.
Six, Chemical Laboratory Floor Plan and Decoration Requirements
(Can be designed according to actual conditions)
Seven, Notes:
This laboratory is designed to meet accreditation requirements. It is generally divided into a chemical analysis room and an instrument analysis room using gypsum board partitions. The layout ensures proper drainage, ventilation, and power supply for the instruments.
A: Fume hood specifications (cm): 150×80×235 with internal fluorescent lighting, includes a small pool for cooling during analysis, and corrosion-resistant countertop with a power outlet.
B: Acid and alkali resistant PPPV material for pools, basins, and drainage pipes (cm): 85×75×85, includes drip stand and triple tap.
C: Dissolution table (cm): 130×75×85, corrosion-resistant countertop with a two-layer reagent shelf.
D: Platform (cm): 90×60×80, marble countertop.
E: Multi-element analyzer table (cm): 110×75×85, physicochemical anti-corrosion surface, space under the table for water collection bin.
F: Carbon-sulfur analyzer table (cm): 150×75×85, ordinary wear-resistant surface.
All tables are 85 cm high and 75 cm wide, with length depending on the layout. The tabletops can be made of phenolic resin or epoxy resin boards. Tables C and E are separated to store glassware and chemicals.
G: Carbon-sulfur analyzer placed in a cylinder cabinet for oxygen cylinder (cm): 50×50×180.
H: Sample preparation area with a steel bench drill base (cm): 100×50×10, anti-vibrating and mobile.
Power Supply: Install 220V three-phase power, each area has a power socket depending on the instrument plug.
Lighting: Two fluorescent lamps per room.
The chemical analysis room can install a window exhaust fan. A large glass partition at 85 cm height allows more light and a sliding door.
The instrument room can serve as a sample storage and should be equipped with air conditioning.
The layout is convenient for daily analysis and operations. However, due to site limitations, the sample table is recommended to be at least 1.5 meters long. Instruments should be spaced out to avoid crowding. If there is space in the upper right corner, the pool can be placed next to the fume hood. Due to the nature of steel testing, the fume hood should not be too small. Bench drills and grinders are needed for tempering laboratories. Because of limited space, grinders may need to be placed elsewhere due to sparks. Bench drills should be medium-sized (over 1,000 yuan) to handle long-term iron drilling effectively.
