Long-arm centrifuge and contact angle measurement unit. (a) Photograph of the long-arm centrifuge and contact angle measurement unit. (b) Diagram of the long-arm centrifuge and contact angle measurement unit. (c) Diagram of centrifugation force. In a gravitational field, the acceleration of an object with the vector sum of the centrifugal and gravity forces at point is , and at point , it is . Owing to , . The centrifugal acceleration gradient of the centrifuge is ~0.0028 G/mm.
