Cyclopore膜

Cyclopore膜

簡(jiǎn)要描述:Whatman聚碳酸脂膜和聚脂膜是孔徑可靠的微孔膜,與已有的徑跡蝕刻膜相比,可以得到非常準確、重復性好的結果。膜光滑平整,可以確保顆粒保留在膜表面,很容易用顯微鏡觀(guān)察到。它是用技術(shù)生產(chǎn)的,微孔分布非常均勻,由純凈聚合薄膜制成,具有*的化學(xué)均一性。該膜是親水性的,可與大多數有機溶劑、氨化物和鹵化碳氫化合物相容。黑色聚碳酸脂膜背景反差大,能增強分析靈敏度,用于熒光和其它顯微鏡法最佳。

Membra-Fil混酯膜

Whatman混合纖維素酯膜是由20%的醋酸纖維素和80%的硝酸纖維素組成。與純硝酸纖維素膜相比,這種膜的表面更加光滑和均勻,而且為顆粒檢驗提供了良好的顏色對比,將眼睛疲勞減至最小程度。

 

光滑或網(wǎng)格

許多微生物技術(shù)包括培養后的克隆計數作為定量的標準方法。Whatman網(wǎng)格濾膜內有間隔3.1mm的網(wǎng)格線(xiàn)。墨水是無(wú)毒,并且*不含有細菌生長(cháng)的抑制劑。

Whatman黑色混酯膜中,平滑型的用于自動(dòng)克隆計數應用,而網(wǎng)格的則用于人工計數。黑膜使得殘留物或細胞顏色和膜之間顏色有差異,不必對膜做染色處理。

 

無(wú)菌膜

對于那些選擇使用通過(guò)消毒的滅菌了的膜的微生物工作,Whatman提供用于實(shí)驗消毒的黑格膜,包括附有墊片。

 

特征和優(yōu)點(diǎn):

有消毒了的膜可供主要實(shí)驗選擇;

非常好的對比,方便顆粒探測;

網(wǎng)格沒(méi)有毒性,也不會(huì )抑制細菌生長(cháng),保證樣品的完整性;

消毒后可重復使用;

黑色平滑或黑格膜中硝酸纖維素和醋酸纖維素的比例為8020;

膜具有高內部面積適合吸附力高的樣品;

更高的灰塵負載力;

低蛋白吸附特性;

生物學(xué)惰性,好的熱穩定性;

沒(méi)有表面活性劑污染樣品;

膜均勻的微孔結構提高了流速;

熱穩定性.

 

應用:

這個(gè)膜在要求更高流速和更大過(guò)濾容量的應用中非常有效,包括水溶液的澄清或消毒,分析和去除顆粒,空氣監測和微生物分析,其他應用包括:

水溶液的澄清或消毒

細胞學(xué)

空氣監測

HPLC樣品制備(水樣)
