The company's sister unit, Tianxin Pharmaceutical, purchased our company's S-300 fully automatic Karl Fischer moisture analyzer in 2019. After the recommendation of the unit, Tianyi Chemical also recently purchased our S-300 fully automatic Karl Fischer moisture analyzer to replace the original imported instrument. As it was recommended by an old customer, the intermediate process was fast, and the price and contract were confirmed within a few days. Our company immediately arranged for shipment, and the customer quickly received the instrument and started using it.
