"Whether to buy imported or domestic equipment" is a must-answer question at every lab construction budget meeting. Simply answering "imported is better, domestic is cheaper" is irresponsible—you should make layered decisions based on the type of instrument, usage scenario, and data purpose.  

Layer 1: Instruments determined by sensor accuracy – recommended to choose imported. DSC, rotational rheometers, DMA, TGA, high-precision universal testing machines (Instron level) – the core value of these instruments lies in sensor accuracy and data repeatability. Imported brands (TA, Mettler, Instron) have decades of experience in sensor design and manufacturing, and still have obvious advantages in sensitivity, baseline stability, and long-term drift control. For R&D departments, when data needs to meet SCI papers or international customer standards, imported brands are a safer choice.  

Layer 2: General-purpose instruments – domestic offers great value for money. Ovens, muffle furnaces, ultrasonic cleaners, pH meters, conductivity meters, basic balances (0.1mg level), Shore hardness testers – the technology for these instruments is already very mature, and high-quality domestic brands can fully meet QC needs, usually at 1/3 to 1/2 the price of imported ones.  

Layer 3: Brand ecosystem – pay attention to software and data compatibility. Large analytical systems like HPLC, GC, and mass spectrometers should be chosen not only based on main unit specs but also considering compatibility with existing lab data systems and software regulatory compliance.
