Cassettes are large (660cc) and easy to fill. Drug cassettes are factory calibrated by Yuyama USA. Yuyama does not use universal type cassettes so there is no need for pharmacy staff to calibrate, test, and re-calibrate the drug cassettes. This system improves counting accuracy, reliability, and drastically cuts down cases of tablets being broken or dropped. No funnels are required. No air compressors are required.
