Antibiotics
Cephalosporins, penicillins, and streptomycin extraction from complex fermentation broths.
System Solutions
Pharma & Biotech Purity by Design
Specialized adsorption and chromatography resin systems engineered for antibiotics, amino acids, and food-grade purification.
Clinical Precision, Global Compliance
In pharmaceutical processing, resin performance directly affects yield, purity, and downstream safety. Linhai provides food and pharma grade systems with specialized post-treatment to minimize leachables.
Provincial Hygiene License
EU REACH Registered
Low TOC Leachable
Amino Acids
Lysine, threonine, and phenylalanine purification with chromatography-ready resin systems.
Food Grade
Sugar decolorization, juice debittering, and citric acid de-ashing support.
Enzyme Systems
Targeted adsorption for high-value protein and specialty ingredient separation.
Antibiotic Extraction Workflow
Our D-Series macroporous adsorption resins are optimized for large-molecule capture from fermentation systems.
Removal of mycelium and suspended solids from the fermentation broth.
Fermentation broth passes through D-Series macroporous resin to capture target molecules.
Captured antibiotics are released with optimized solvent mixtures, pH, and flow-rate control.
Final concentration and crystallization of the high-purity active pharmaceutical ingredient.
Why pore size distribution matters
Pharmaceutical separations involve large organic molecules. Linhai controlled-porosity technology aligns average pore size with target molecular weight so the working surface area stays effective and kinetics remain fast.
