Stervility da kuma hanawa
Lokacin amfani da samfurori na ilimin halitta, saci yana da mahimmanci. Zabi al'adun gargajiya waɗanda ke da alama bakararre bakararre ko autoclawable don tabbatar da cewa ba za su gabatar da fa'ida a cikin samfuranku ba. Bugu da ƙari, yi la'akari da bututun filastik waɗanda za a iya amfani da su yayin da suke kulawa da al'adun da suke da hankali don rage haɗarin gurbatawa.
Zabi bututun na al'ada na dama yana buƙatar la'akari da hankali sosai, gami da fasalin zane, kayan aikin kayan, da buƙatun girman, da takamaiman aikace-aikace.
