Na li-blenders tsa lab tsa matsoele li ka sebetsana le lisampole tse kholo tsa molumo?

Selelekela hoho kopanya lab ea stomachers

Li-blender tsa stomacher lab ke lisebelisoa tsa bohlokoa lithutong tse fapaneng tsa mahlale, tse tsebahalang ka bokhoni ba tsona ba ho etsa lisampole ka nepo ho tloha ho lihlahisoa tsa lijo ho isa ho tsa tikoloho. Moralo oa bona o tsoetseng pele o lumella ho sebetsa ha lisampole tse nyane le tse kholo, tse fanang ka tharollo e fapaneng bakeng sa lilaboratori lefatšeng ka bophara. Sengoliloeng sena se shebana le bokhoni le ts'ebeliso ea li-sumbaster blender, se shebane le bokhoni ba bona ba ho sebetsana le lisampole tse kholo tsa molumo, 'me se totobatsa karolo ea bahlahisi le barekisi ba bohlokoa, ho kenyeletsoa le ba tsoang China.

Mehlala e Meholo ea Mehlala ea Bokhoni ba ho Tšoara

Bokhoni ba ho Kopanya le Bokhabane

Li-blender tsa limpa li etselitsoe ho laola boholo ba sampole ho tloha ho 400 ml ho isa ho 4500 ml, ho li etsa hore li tšoanelehe bakeng sa tokiso ea sampole e kholo. Ho feto-fetoha ha maemo hona ho molemo haholo bakeng sa lilaboratori tse sebetsanang le lisampole tse ngata, joalo ka tse hlokoang litekong tsa polokeho ea lijo le tlhahlobo ea tikoloho. Bokhoni ba li-blenders bo tlatselletsoa ke bokhoni ba bona ba ho pshatla matrices a rarahaneng, ho netefatsa kabo e tšoanang ea lisele tsa likokoana-hloko ho pholletsa le sampole.

Nako-Melemo ea ho Boloka

Bokhoni ba ho sebetsana le lisampole tse kholo ts'ebetsong e le 'ngoe bo fokotsa haholo nako e hlokahalang bakeng sa ho lokisetsa sampole. Ka ho sebetsana le lisampole tse kopantsoeng tse fihlang ho 375g habonolo, li-stuster blender li felisa tlhoko ea litlhahlobo tse ngata, tse nyane, ka hona ho ntlafatsa ts'ebetso ea laboratori le ho fokotsa litšenyehelo tsa basebetsi.

FDA's Bacteriological Analytical Manual Relevance

Ho lumellana le BAM Protocols

E 'ngoe ea lits'ebetso tsa bohlokoa tsa li-sumbaster blender ke litlhahlobo tsa likokoana-hloko tse tataisoang ke FDA's Bacteriological Analytical Manual (BAM). Li-blenders tsena li etselitsoe ho lokisa lisampole ho latela litataiso tsa BAM, tseo hangata li hlokang lisampole tse kopaneng tsa 375g ho fumana Salmonella. Ka ho etsa bonnete ba ho latela melaoana ena e thata, lilaboratori li ka fihlela liphetho tse tšepahalang le tse ka hlahisoang hape.
