产品详细介绍 |
Kenker聚碳酸酯膜(PolycarbonateM) 在严格控制的条件下生产和检测,保证了精确的孔径,可进行精确的依据孔径的分离,以保证用户足够好的使用体验。表面光滑如镜面,可以在各类显微镜下进行清晰的观察。背景干扰低,在大多数应用中无需进行清洗,而不会造成污染。皮重低、最小吸水量已经达到非常低的水平。Kenker聚碳酸酯膜亲水,具有广泛的化学相容性,适用于许多腐蚀性溶液中的颗粒探测。
性能: ·利于显微观察。 ·表面光滑,孔径精确 ·吸附少(无吸附)、无介质脱落 ·吸水量非常低 ·皮重低 ·生物学惰性良好 ·耐腐蚀
应用: ·空气质素检测 ·水质量检测 ·过滤及细胞分析 ·显微观察 ·微生物分析 ·浮游生物研究
注意事项: kenker membranes尽可能的为用户提供更多类型的产品,但在某些时间并非所有孔径的膜都有不同尺寸滤膜可选,请联系于您最便利的kenker membranes销售商以确认z新的产品讯息。
关于kenker membranes的技术性资料: 一、Kenker Noun: 1、Absolute pore size绝对孔径:绝对孔径是指通过在十分严格的测试条件下100% 截留下某种特定尺寸的挑战菌来区分孔径。必须指明的条件里有:测试有机体(或分子)尺寸及浓度,测试压力和检测方法。 2. Air flux空气通量:在不同的压力、不同的孔率和不同滤器面积情况下,空气所流过的流量。 3. Bubble point气泡点:使用特定液体浸润滤膜,在特定温度下,所须排挤出滤膜孔中液体的最小压力。 4. Hydrophilicity亲水性:亲水性的滤膜通常有一层特殊化学层使得滤膜可以被水浸润; Hydrophobiity 是对水的斥力的一个参考。疏水性滤膜很少充分不吸水。在观察上可目视小水液滴停留在滤膜的表面而不会被表面吸附而扩散成水面。疏水性的大小取决于滤材的孔径和滤膜原料的特性。 5. 流率和流量:流率是在特定温度及压力下单位时间内过滤液通过滤膜的总量。流率与滤膜表面性质有密切关系。流率和通量是微孔滤膜性能的二个重要参数。这种性能取决于以下几个方面: 1)粘性:粘度决定了液体流动的难易。液体的粘度越高(在一定的温度和压力条件下)流率越低。而要达到相同流率时所需的压力越高。 2)压力差:过滤中进口与出口的压力差,当滤器的满负荷时,过滤压力差增大。 3) Porosity孔率:是指滤膜上所有孔的体积占全部滤膜体积的比例。流率与膜的孔率有直接的关系。
二、选择滤膜滤膜要考虑的因素 微孔滤膜的主要功能是从气相或者液相中截留微粒,细菌及其他杂质,以达到分离,净化,提纯的目的。因此选择滤膜要考虑以下几个因素: 1.滤膜的材质(化学兼容性):选择滤膜时,首先要考虑化学相容性。滤器是否耐酸、碱、有机溶剂等。具体参见滤膜化学相容性表。 2.滤膜的孔径:根据需要过滤的分子或颗粒的大小来确定正确范围的滤膜孔径。 3.样品的特性: 1)亲水性样品:选用亲水膜片。对水有亲和力,适合过滤水为基质的溶液。可用的滤膜有:混合纤维素膜,聚醚砜(PEsM),NylonM等。 2)强腐蚀性有机溶剂:一般采用疏水性膜。如PTFEM,聚丙烯(PPM)等材质的滤膜 3)蛋白溶液:选择低蛋白吸附的滤膜,如PVDF滤膜。 4)离子色谱:通常认为PEs滤膜比较适合低无机离子的溶液的过滤。
