The Chutian Pet Peptide Synthesis Instrument adopts a patented 180 degree up and down flip mixing mode, which is uniform without dead corners, does not damage the resin, and has an average amino acid coupling rate of up to 99%. With the same feeding ratio, the yield is higher, the purity is higher, and the single impurity is lower, reducing the subsequent purification cost. It is the first choice for the synthesis of long peptides and complex peptides.
