User Guide 1. All products of this series are scientific research-grade consumables, only for laboratory scientific research, not for medical injection or industrial end products, and are prohibited from direct human clinical injection, treatment and large-scale industrial production. 2. The products need to be sealed and refrigerated at 2~8°C away from light. Freezing, high-temperature exposure, long-term storage at room temperature and repeated freeze-thaw are strictly prohibited. It is recommended to use up within 1 month after opening to prevent decreased dispersion stability and slight agglomeration of microspheres. 3. All series support personalized surface function customization such as hydrophilic modification, functional group grafting and fluorescent labeling. The quotation and production cycle vary with different customization schemes. Please consult customer service to confirm detailed parameters before ordering. 4. The parameters in this specification are general standard values. Minor physical deviations between batches are within the industry allowable error range and will not affect conventional scientific research experiments and instrument calibration. 5. PE microspheres are inert non-degradable materials with stable chemical properties, but long-term exposure to strong oxidation and ultra-high temperature environments should be avoided to prevent changes in surface performance and ensure experimental consistency.
