WHATMAN 1827-110濾紙

用(yong)(yong)(yong)這種普遍的(de)(de)濾(lv)紙截流細(xi)小(xiao)顆粒(li)的(de)(de)優越(yue)性，在(zai)于(yu)快(kuai)流速和(he)高負載力下有著非常(chang)高的(de)(de)保留(liu)效率。這是(shi)種表(biao)面光滑，高保留(liu)力的(de)(de)硼硅酸微纖(xian)維濾(lv)紙，可耐(nai)高溫達(da)500攝氏度。用(yong)(yong)(yong)于(yu)測定水(shui)(shui)中(zhong)懸浮物總數(shu)去除渾(hun)濁(zhuo)物和(he)細(xi)菌培(pei)養的(de)(de)過(guo)(guo)濾(lv)。Grade 934-AH用(yong)(yong)(yong)于(yu)很多范圍的(de)(de)實驗室應用(yong)(yong)(yong)中(zhong)。推薦(jian)用(yong)(yong)(yong)于(yu)水(shui)(shui)污(wu)染監測、細(xi)胞培(pei)養、液(ye)閃計(ji)數(shu)和(he)空氣污(wu)染監測。大部分(fen)濾(lv)紙由棉質纖(xian)維組成，按不(bu)同(tong)的(de)(de)用(yong)(yong)(yong)途而使用(yong)(yong)(yong)不(bu)同(tong)的(de)(de)方(fang)法制作。由于(yu)其材質是(shi)纖(xian)維制成品(pin)，因此它的(de)(de)表(biao)面有無數(shu)小(xiao)孔可供液(ye)體粒(li)子通過(guo)(guo)，而體積較大的(de)(de)固體粒(li)子則不(bu)能通過(guo)(guo)。這種性質容許混(hun)合在(zai)一起的(de)(de)液(ye)態(tai)及固態(tai)物質分(fen)離。

濾(lv)(lv)紙(zhi)(zhi)(zhi)一(yi)般(ban)可(ke)(ke)分(fen)(fen)為定(ding)性(xing)(xing)(xing)及定(ding)量兩(liang)種。在分(fen)(fen)析(xi)化學的(de)(de)(de)(de)應(ying)(ying)(ying)用(yong)(yong)(yong)(yong)中(zhong)(zhong)，當無機化合物經(jing)過過濾(lv)(lv)分(fen)(fen)隔出沉淀物后(hou)，收(shou)集在濾(lv)(lv)紙(zhi)(zhi)(zhi)上(shang)(shang)(shang)的(de)(de)(de)(de)殘余(yu)物，可(ke)(ke)用(yong)(yong)(yong)(yong)作(zuo)(zuo)計算實驗(yan)過程中(zhong)(zhong)的(de)(de)(de)(de)流失率。定(ding)性(xing)(xing)(xing)濾(lv)(lv)紙(zhi)(zhi)(zhi)經(jing)過過濾(lv)(lv)后(hou)有(you)較多的(de)(de)(de)(de)棉(mian)質纖維(wei)(wei)生(sheng)(sheng)成，因此(ci)只適用(yong)(yong)(yong)(yong)于(yu)作(zuo)(zuo)定(ding)性(xing)(xing)(xing)分(fen)(fen)析(xi)；定(ding)量濾(lv)(lv)紙(zhi)(zhi)(zhi)，特別(bie)是無灰級的(de)(de)(de)(de)濾(lv)(lv)紙(zhi)(zhi)(zhi)經(jing)過特別(bie)的(de)(de)(de)(de)處理程序，能(neng)夠較有(you)效(xiao)地抵(di)抗化學反(fan)應(ying)(ying)(ying)，因此(ci)所(suo)生(sheng)(sheng)成的(de)(de)(de)(de)雜質較少，可(ke)(ke)用(yong)(yong)(yong)(yong)作(zuo)(zuo)定(ding)量分(fen)(fen)析(xi)。除了(le)一(yi)般(ban)實驗(yan)室(shi)應(ying)(ying)(ying)用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)濾(lv)(lv)紙(zhi)(zhi)(zhi)外，生(sheng)(sheng)活上(shang)(shang)(shang)及工程上(shang)(shang)(shang)濾(lv)(lv)紙(zhi)(zhi)(zhi)的(de)(de)(de)(de)應(ying)(ying)(ying)用(yong)(yong)(yong)(yong)也很多。咖啡(fei)濾(lv)(lv)紙(zhi)(zhi)(zhi)就是其中(zhong)(zhong)一(yi)種被廣泛(fan)應(ying)(ying)(ying)用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)濾(lv)(lv)紙(zhi)(zhi)(zhi)，茶包外層(ceng)的(de)(de)(de)(de)濾(lv)(lv)紙(zhi)(zhi)(zhi)則提供了(le)高柔軟(ruan)度及濕強度高等特性(xing)(xing)(xing)。其它使用(yong)(yong)(yong)(yong)測試空氣(qi)中(zhong)(zhong)懸浮粒子(zi)的(de)(de)(de)(de)空氣(qi)濾(lv)(lv)紙(zhi)(zhi)(zhi)，及不(bu)同(tong)工業(ye)應(ying)(ying)(ying)用(yong)(yong)(yong)(yong)上(shang)(shang)(shang)的(de)(de)(de)(de)纖維(wei)(wei)濾(lv)(lv)紙(zhi)(zhi)(zhi)等。
