Ukucaciswa:

Isingeniso:

Ithiyibhile yokuqina kwegunya iyisampula esiphathelene sayiprofeshini esenzakalayo esidolophithwe ukuthatha isampula yegunya ngendlela efanayo, ukuyilondoloza nokuthumela. Inetholakala ngamakhapo amabili ama-2ml ne-5ml, ngayinye inikezwa noma ingenagebani ukulandelela izidingo ezahlukene. Isakhiwo sakhe esifanayo nobubi bethu sikhuphela umkhombandlela wokusebenza, sibe yisizo kubasebenzi basephakethini nabasebenzi abaqhamuka ekhaya.

Ukuthatha isampula ngokuefficient yindlela ephathelene ngesilingo senzo. Inguqu lapho kunezinkawu zokuthatha isampula zenziwe ngokuchaza i-spoon-shaped head, inokuthatha isampula esilinganiswe ngendlela eyodwa ngaphandle kokunqamuziwa kumusha, ukukhulula ukungena kwesampula ngaphakathi. Inguqu engenazo izinkawu ihlotshelwe ukuthatha izampula zomlilo noma zomthwalo, ngegama elilungele kangako elingaphansi elimandla ukuthola isampula ngaphezu kakhulu. Isihlangothi sezinhlayiya sibhalwe ngamadoda amancane, okwenzela abasebenzisi bakwazi ukulawula kakhulu ixabiso le-sampling ngokulingana nezidingo zokuhlola.

Ngokuphathelene kahle nokulandelana kwezimo eziningi, ithiyibhu yenziwe ngomthelelo wasekhankalini PP, owenziwa ngokugcwele, oqinile chemically, onamandla ekuphileni kwicala phansi kwe-temperature kunye namandla, kwaye ungalondolozwa ngqo kumthwalo we-nucleic acid othabatha kunye nezixhobo zokuzalisela ngaphandle kokuthabatha isampula. Isikruli esigcinayo sangaphandle nesiphazamo singaqinisekisa ukungafuni kwisampula ngexesha lokuthunyelwa, kwaye intonga evela yekhlariti iyaphumelela iingcamango zokuphepha kwiinkwenkwe, iinkundla zokuphatha izifo kunye nezilaborithori zokulinganisa.
