Nuclepore filter
A Nuclepore filter (aha aha Nuclepore sitere na Whatman, akụkụ nke GE Healthcare) bụ ụdị nzacha nke e mepụtara oghere micrometers ole na ole n'ogo na plastik (dịka polycarbonate) membrane. A na-emepụta nzacha ndị a site n'ikpughe membrane na radiation nke na-eme ka plastik ghara ịdị ike ma mepụta mpaghara ụfọdụ nke enwere ike iwepụ site na itinye membrane na acid (ma ọ bụ kemịkal ndị ọzọ). Robert L. Fleischer, P. Buford Price, na Robert M. Walker mepụtara usoro [1] na patent dị ka ihe sitere na nyocha ha gbasara mmetụta radiation na ihe siri ike, na-elekwasị anya pụrụ iche na ihe ndị na-ekpughe na ụmụ irighiri ike na mbara igwe. Usoro a na-enye ohere ịmepụta oghere ejiji nke ọ bụla achọrọ iji kwe ka a nyochaa ọbụna nje virus.
Ihe a na-ejikarị eme ihe nzacha Nuclepore bụ na microbiology ebe a na-eji ha na-ejide mkpụrụ ndụ mgbe ha na-ewepụ mmiri ndị ọzọ niile na ihe ndị dị nta, dịka. maka ịgụta nje bacteria site na microscopy fluorescence. N'ihi na ihe nzacha ndị ahụ nwere elu dị larịị, mkpụrụ ndụ ndị ahụ na-ejide n'elu nzacha ahụ ma nọgide na-ahụ anya, n'adịghị ka ụdị ihe nzacha ndị ọzọ ebe mkpụrụ ndụ nwere ike ịbanye n'ime nzacha.[2]
