Before helping customers make laboratory design layout, we usually fully understand the customer’s experimental methods, standards, instruments The equipment situation, the individual needs of customers and the relevant external conditions of the laboratory are then analyzed and planned, so as to form a complete and scientific laboratory design and planning drawings, and in-depth design drawings such as similar water, electricity, heating and ventilation.

This involves a lot of testing and laboratory expertise. Unprofessional design teams may not be able to understand customer needs in-depth when doing laboratory design, causing certain laboratory design risks. Let’s take the environmental reliability laboratory as an example. , A brief overview of some possible risks in laboratory design.

Laboratory design risk case: Risks encountered in the design and layout of environmental reliability laboratory

Risk 1: The laboratory design company does not understand the equipment installation requirements, causing the laboratory equipment to be unable to install, such as:

X-ray diffraction equipment requires circulating water (divided into internal and external units). According to the installation requirements of the equipment, the distance between the internal and external units of the circulating water should not exceed 4 meters, and the internal unit and the instrument host should not exceed 8 meters. Therefore, X-ray diffraction equipment can only be placed in a location that is conducive to ventilation and heat dissipation or where there is a special space to place the circulating water outside machine.

The same problem will occur in other equipment that needs to use circulating cooling water, such as a simultaneous thermal analyzer-infrared-mass spectrometer; hydraulic fatigue testing machine, etc.

Risk 2: The laboratory design company does not understand the environmental conditions of the test project, resulting in no special facilities, and the test project cannot be carried out normally because the environmental conditions do not meet the standard requirements.

In testing of physical and mechanical properties of non-metallic materials, most of the samples need to be pretreated in accordance with the requirements of GB/T 2918. For example: (23±1)°C, (50±5)%, 88h; therefore, when the sample volume is large, a constant temperature and humidity room needs to be built, and the placement of the internal unit of the constant temperature and humidity air conditioner needs to be considered.

Risk 3: The laboratory design company does not understand the possible mutual interference between the test items, resulting in: 1. Equipment damage; 2. Test results are interfered and inaccurate; 3. Security risks

1. Cases of equipment damage caused by laboratory design layout: The environment of the electron microscope installation requires no vibration, otherwise it will affect the accuracy of the experiment. Therefore, the layout of the laboratory design in the lower left picture is unreasonable unless an anti-vibration slot is dug between the machine and the electron microscope.

2. Cases of laboratory safety risks caused by laboratory design layout

The high-temperature drying oven, muffle furnace, etc. are placed in the pre-treatment room. The pre-treatment room often uses various reagents, some of which have extremely low ignition and flash points, while the high-temperature oven is often unattended operation for a long time , It is easy to cause fire or even explosion.

The unreasonable design and layout of the laboratory lead to safety risks, as well as the storage of reagents in the laboratory, the mixed storage of various properties, or the ventilation is not considered; the storage of laboratory gas is flammable, explosive and combustion-supporting Separate placement of flammable and explosive gas chambers; consider the venting of flammable and explosive gas chambers; heat dissipation of operating heating equipment such as UPS and air compressors...
