Nā hiʻohiʻona noi a me ke alakaʻi kūʻai ʻana o nā paipu centrifuge a me nā centrifuges

Hōʻuluʻulu kēia ʻatikala i kekahi mau ʻike e pili ana i ka noi hoʻokaʻawale ʻana, kūʻai i ke alakaʻi a me ka ʻōlelo hōʻailona o nā paipu centrifuge, ultrafiltration centrifuge tubes a me nā centrifuges laboratory, me ka manaʻo e kōkua iā ʻoe.

Hoʻokomo ʻia ka hāpana hoʻokuʻu i loko o kahi pahu hāpana tubular.Ma lalo o ke kiʻekiʻe-wikiwiki rotation o ka centrifuge, ka suspended liilii particles (e like me ka precipitation o organelles, biological macromolecules, etc.) e noho ma kekahi wikiwiki ma muli o ka nui centrifugal ikaika, i hiki ke hookaawale ia lakou mai ka hopena.ʻO kēia ʻano ipu laʻana tubular me ka uhi sila a i ʻole ka gland i kapa ʻia ʻo centrifuge tube.

Nā hiʻohiʻona noi a me ke alakaʻi kūʻai ʻana o nā mea like ʻole o nā paipu centrifuge:

1. Paipu centrifuge plastik

ʻO nā mea maikaʻi o ka plastic centrifuge tube he aniani a translucent paha, he liʻiliʻi kona paʻakikī, a hiki ke lawe ʻia ka hāpana ma ka puncture.ʻO nā hemahema he maʻalahi deformation, kūʻē maikaʻi ʻole i ka corrosion solvent organik a me ke ola lawelawe pōkole.

He mau pāpale ko nā paipu centrifuge plastik, i hoʻohana ʻia no ka pale ʻana i ka leakage o nā laʻana, ʻoi loa ke hoʻohana ʻia no nā mea radioactive a i ʻole nā ​​​​mea ʻino loa;Hoʻohana pū ʻia ka uhi o ka paipu e pale aku i ka volatilization hāpana a kākoʻo i ka paipu centrifuge e pale i ka deformation o ka paipu centrifuge.I ke koho ʻana i kēia wahi, e makaʻala e nānā inā paʻa ka uhi paipu, a inā hiki ke uhi paʻa ʻia i ka wā o ka hoʻāʻo ʻana, i mea e pale aku ai i ka leakage wai ke hoʻohuli ʻia.

Ma waena o nā paipu centrifuge plastic, nā mea maʻamau he polyethylene (PE), polycarbonate (PC), polypropylene (PP), a me nā mea'ē aʻe.No laila, ho'āʻo mākou e noʻonoʻo i nā paipu centrifuge plastic polypropylene i ke koho ʻana i nā paipu centrifuge plastic.ʻO nā paipu centrifuge plastik ka mea hana hoʻokolohua maʻamau, a ʻaʻole ʻōlelo ʻia ka hoʻohana pinepine ʻana.I mea e mālama ai i ke kālā, hiki ke hoʻohana hou ʻia nā paipu centrifuge PP e like me ka hihia, akā pono lākou e hoʻomaʻemaʻe maikaʻi ʻia ma lalo o ke kiʻekiʻe o ka mahana a me ke kaomi e hōʻoia i nā hopena ʻepekema o ka hoʻokolohua.ʻAʻole hiki ke hoʻopaʻa ʻia ka paipu centrifuge PE ma lalo o ke kiʻekiʻe o ka wela a me ke kaomi.

ʻO ka ikaika centrifugal i hiki i ka huahana ke halihali a i ʻole ka wikiwiki i ʻōlelo ʻia e hōʻike maʻamau ʻia i loko o ka ʻeke a i ʻole nā ​​ʻōlelo aʻoaʻo o ka paipu centrifuge plastic.I mea e hōʻoiaʻiʻo ai i ka palekana o ka hoʻokolohua a me ka hilinaʻi o nā hopena, pono e koho ʻia ka tube centrifuge e hoʻokō i nā koi wikiwiki o ka hoʻokolohua.

2. Pupu aniani centrifuge

I ka hoʻohana ʻana i nā paipu aniani, ʻaʻole pono ka nui o ka ikaika centrifugal, a pono e kau ʻia nā pad rubber e pale ai i ka haki ʻana o nā paipu.ʻAʻole hoʻohana nā centrifuges kiʻekiʻe i nā paipu aniani.Inā ʻaʻole maikaʻi ka pani ʻana o ka pahu centrifuge, ʻaʻole hiki ke hoʻopiha ʻia ka wai (no nā centrifuges kiʻekiʻe kiʻekiʻe, hoʻohana ʻia nā rotors angle) i mea e pale ai i ke kahe a me ka nalowale o ke koena.ʻO ka hopena o ka overflow e hoʻohaumia i ka rotor a me ke keʻena centrifugal, e pili ana i ka hana maʻamau o ka inductor.I ka wā o ka ultracentrifugation, pono e hoʻopiha ʻia ka pahu centrifuge me ka wai, no ka mea, ʻo ka ultracentrifugation e koi ai i ka momi kiʻekiʻe, a hiki ke pale ʻia ka deformation o ka tube centrifuge ma ka hoʻopiha wale ʻana.

3. Ke kila centrifug

He kiʻekiʻe ka ikaika o ka ipu hao centrifuge, ʻaʻole deform, a kūpaʻa i ka wela, ka hau a me ka corrosion kemika.Hoʻohana nui ʻia ia, akā pono e pale aku i ka hoʻopili ʻana i nā kemika corrosive ikaika, e like me nā waikawa ikaika a me nā alkalis.E ho'āʻo e pale i ka ʻino o kēia mau mea kemika.
