磨损测试装置PTF 20 e

平板电脑 对实验室 数字

PTF 20E双鼓固定速度片剂脆碎仪是按照美国药典(USP)、EP和其他药典生产的。此版本可作为单鼓或双鼓乐器。片剂和芯材机械强度的测试标准之一是脆性和磨损测试。在包衣、运输和包装过程中，片剂会有一定的重量损失。为了测量重量损失，对样品进行计数和称重。然后根据相关药典的各论进行脆性试验。在易碎性测试仪器的滚筒每转一圈，就通过一个从滚筒中间延伸到外壁的弯曲凸起来翻滚药片。一旦脆性测试完成，样品必须除尘并再次称重。确定试验前后的重量差为脆性;这通常不应超过1%。 Tablets of a weight >650mg or with a bigger diameter or odd shaped samples are tested while the instrument is raised on one side using collapsible feet to an angle of 10%. Additional Abrasion Drums The standard supply scope includes the friability (also known as “Roche”) drums, but abrasion drums are available as options. The standard friability drum causes the samples to roll and fall during the test while the abrasion drum continuously puts the sample under stress by contact with lamellas
