SpectraPor® Tubing Closures

SpectraPor^® 透析膜夹提供三种功能类型，设计用于再生纤维素 (RC) 透析膜管，以确保防漏密封。此类膜夹不推荐用于纤维素酯 (CE)膜。

Standard Type Closure

SpectraPor^® Standard Closures float and aid in sample buoyancy when applied to the top-end of the dialysis tubing; autoclavable and available in a variety of colors for easy sample identification.
