Routine Maintenance and Troubleshooting for Freezing Point Osmometers
After daily use, wipe the instrument's exterior casing with a soft, dry cloth to remove dust and stains, preventing them from entering the instrument's interior and affecting performance. For critical components such as the sample needle and stirring paddle, use specialized cleaning tools—such as a cotton swab dipped in a small amount of alcohol—to gently wipe away residual samples and impurities. This prevents clogging or corrosion and ensures measurement accuracy.Open the lid and receive a prize - fetal bovine serum activity revealed!
