Syvinge fyulufa imatchedwanso ngati syving syvite. Ichi ndi fyuluta yachangu, yosavuta, komanso yodalirika ya zitsanzo zazing'ono. Laboratoes amagwiritsa ntchito ngati gawo lantchito yawo yokhazikika. Imakhala ngati fyuluta yayikulu pokonzekera zitsanzo. Ili zosefera ndi saberelives a lab zakumwa, chikhalidwe cha chikhalidwe, ndi zowonjezera. Imagwira ntchito ndi ma syringe otayika.
Zosefera Syringe ndizofunikira pakusefedwa. Iwo samatenthetsa ndi kusefa madzi ndi okhazikika (monga HPLC, UHPLC). Ndiye tiyenera kusankha bwanji kuchokera ku mitundu yosiyanasiyana yosefera ndi zosefera mitundu? Kuwerenga nkhaniyi kufotokozeranso kukayikira kwanu.
Makonda
Zosefera Syringe ali ndi kukula kwa 4 mm, 13-15 mm, 25-28 mm, 33 mm, ndi 50 mm. Chromatographic zitsanzo zojambulajambula zimagwiritsa ntchito13 mmndi 25 mm kukula ngati muyezo.
Kusankha kukula kolondola kosinthanitsa, tiyenera kutsatira lamuloli: Voliyumu imayenda ngati Fyuluta imakula. Kuti muchepetse kutayika kwake ndikuchepetsa nembanemba kuti muchepetse, sankhani filimu yosefera potengera kuchuluka kwa zitsanzo.
Syring zosefera za maomwe a diameters osiyanasiyana.
4 mm: yolimbikitsidwa 0,05 ml - 1 ml ya kusefa
13-15 mm: Zoyenera kwa 1 ml - 10 ml ya kusefa
25-28 mm: yolimbikitsidwa 10 ml - 50 ml ya kusefa
33 mm: Adayenera kwa 10 ml - 100 ml ya kusefa
50 mm: yolimbikitsidwa 100 ml - 500 ml ya kusefa
A25 mm syngequeili ndi mfundo yapamwamba kuposa 13 mm fluluto. Fyssing Sysnge Fva Fyuluta ili ndi malo ambiri osokoneza bongo ndipo imatha kuthana ndi mavidiyo ambiri. Fy 13 mm syngequesefa ndiyotsika mtengo. Ndioyenera kukonza zitsanzo zazing'ono.
Pures
Kukula kwapakatikati kwa nembanemba kulinso chifukwa chothira staving sfay. Mitundu yayikulu ya nembanemba ya nems ndi 0,1 μm, 0.20 mpaka 0.22 μm, 0.45 μm, 0,8 μ, 0,8 μm Pures ya Pores 0.22 μm ndi 0.45 μm mapulogalamu a HPLP ndi GC.
Zojambulajambula zogwiritsa ntchito syring zosefera ndi zigawo zosiyanasiyana.
A0.22 μm syvingesenthawi zambiri imagwiritsidwa ntchito posefedwa. Kukula kwa 0,22 μm kore kumakopa mabakiteriya komanso tizilombo toyambitsa matenda. Kuyesedwa ndi kwa zitsanzo. Zimafuna chilengedwe chosatha. Kugwiritsa ntchito fayilo ya 0,22 μm μm. Izi zili choncho popanga mankhwala, zinthu zachilengedwe, komanso mayankho jakisoni. Ndizowonanso popanga chikhalidwe. Muthanso kugwiritsa ntchito pochotsa tinthu tating'onoting'ono, chikhalidwe cha khungu, komanso zina zambiri.
A0,45 μm syvingeseamapeza tinthu tambiri kuchokera ku zakumwa zolondola. Itha kuchotsa tinthu tating'onoting'ono. Ndizabwino kwambiri kuphulika. Ofufuza amafunikira ntchito. Amagwiritsa ntchito njira zopezera zitsanzo za chilengedwe, zotayika, ndi zakudya zina. Zimachotsa tinthu tambiri kuchokera pa zitsanzo molondola. Itha kusokoneza zitsanzo musanayambe kusanthula. Izi zimachotsa nkhani yoyimitsidwa kuti tisawononge chromaphiphy.

Maganizo a kuchuluka
Ma diameter osiyanasiyana ndi zigawo za pore ali ndi zotsatira zosiyanasiyana zakufalikira. Mphamvu kwambiri ndi liwiro la kusefa ndi kuchuluka kwa mawu a nembanemba.
Kuthamanga kwa Filler
Chifukwa kukula kwa cores kuli ndi malo osokoneza bongo, padzakhala kuchuluka kwakukulu pakukankhira syringe. Zosefera zazing'ono zazing'ono zimakhala ndi malo ocheperako, kotero kuti mtengo woyenda umasachedwa kuposa zosefera zazikulu. Zosefera zazing'ono zazing'ono ndizoyenera kuziseka zitsanzo zazing'ono kapena nthawi zomwe zimapangitsa kuti mpweya ukhale wosafunikira.
Kugwiritsa ntchito voliyumu yazosefera.
Zosefera zazing'onozing'ono zazing'ono zimakhala ndi magwiridwe ang'onoang'ono osungirako kuposa zosefera zazikulu. Ma voliyumu ang'onoang'ono okhazikika amatanthauza kuti sample pang'ono imasungidwa mu membrane wocheperako ndikukhala ndi nyumba za syreming kunyumba nthawi yachitsanzo, yomwe imatha kuchepetsa kutaya kwamtengo wapatali komanso yoyenera kwambiri.
Zosefera zazing'onoting'ono ndi zazikuluzikulu zimakhala ndi zabwino zawo. Mukamasankha zosefera, zoyeserera ziyenera kusankha kukula koyenera ka snyungeyi molingana ndi zofunikira za zida zoyesera ndi zitsanzo zosefera.
Lumikizanani nafe
Ehileraimapereka zoseweretsa za syring. Zosefera syringe ndi zinthu zotayika ndipo sizikulimbikitsidwa kuti zithandizirenso zotsalira za zitsanzo zomwe zimachitika kuti zitheke. Komabe, ngati zitsanzo zomwezo zikukonzedwa, zitha kugwiritsidwanso ntchito katatu katatu.
