说明
一般描述
Membrane filtration before separation via liquid chromatography removes contaminating particles from solvents and mobile phases, increasing column life, preventing system failure, and ensuring pure samples for downstream mass spectrometric analysis.
应用
Durapore PVDF membranes are utilized in a variety of biomedical research applications.
特点和优势
provides high flow rates and throughput, low extractables, and broad chemical compatibility
solvent and heat resistant
exhibits very low protein binding to minimize interaction with the sample and maximize recovery
varied pores sizes to suit different application needs
其他说明
使用说明
生物截留:微生物
作用机制:过滤(体积排阻)
应用:一般实验室过滤
预期用途:截留或去除生物污染物
使用说明:通过孔径0.2 μm(或更小)的膜进行液体的除菌过滤可有效去除生物污染物,包括细菌、霉菌和酵母菌。 为了选择性地截留较大的生物污染物,可用孔径0.45μ m(或更大)的膜过滤液体以捕获并支持微生物的生长,然后进行培养和分析。
储存申明:干燥储存
处置声明:根据国家、省市和当地适用法规处置。
