Addressing Industry Issues
The product quality requirements are extremely high, and batch consistency is difficult to control: fluctuations in liquid level/pressure lead to purity not meeting standards, low yield, large batch differences, and high scrap rates (fine chemical scrap losses can reach 120000 yuan/month).
The risk of cleanliness/sterility is prominent
Ordinary instruments have blind spots, are prone to residue, difficult to sterilize, breed microorganisms, contaminate raw materials/preparations, and violate GMP.
Strong corrosion/organic solvent erosion
Acid alkali and organic solvent corrosion of ordinary instruments, probe damage, medium contamination, measurement failure.
Strict parameter control and large manual errors
With multiple varieties and small batches, manual batching/adjustment errors are large, inefficient, and prone to errors, affecting quality and delivery time.
Dual pressure of explosion-proof safety and GMP compliance
Organic solvents are flammable and explosive, while ordinary instruments are prone to explosions; Data cannot be traced and non-compliance may result in production suspension fines.
