Kuchenesa Kuraswa Kwevacuum

1. Sisitimu iyi inosanganisira funnel yepolystyrene ine mutsipa wepolyethylene uye bhodhoro rekuchengetera polystyrene rinobviswa.
2. Mavhoriyamu(ml): 150,250,500 uye 1000.
3. Ma membrane efirita: Nayiloni, PES, Hydrophilic PVDF/MCE/CA.
4. Saizi yePore(μm):0.22 uye 0.45.
5. Inoshandiswa zvakanyanya pakusefa nekuchengetedza midziyo yekudyara masero, mvura yemuzvarirwo, uye mimwe mhinduro dzemvura.

Munyaya yekutsvagisa murabhoritari uye bioprocessing, kushanda zvakanaka uye kuvimbika ndizvo zvinonyanya kukosha. Masisitimu ekusefa evacuum anoraswa inzira inozivikanwa uye itsva. Yakagadzirirwa kurerutsa maitiro ekusefa, masisitimu aya ave chishandiso chakakosha kune vaongorori nemasayendisiti.

Pakati pechinhu ichi ifunnel yepolystyrene ine mutsipa wepolyethylene, iyo inoita kuti pave nekubatana kwakachengeteka uye kusingadonhe mvura. Bhodhoro rekuchengetera repolystyrene rinobviswa rinoita kuti zvive nyore kuunganidza nekuchengeta sampuro dzakasefetwa, zvichiita kuti ive sarudzo inoshanda kuma laboratories ane mabasa akawanda. Sisitimu iyi inowanikwa mumhando dzakasiyana-siyana - 150ml, 250ml, 500ml uye 1000ml - kuti igutse zvido zvakasiyana-siyana zvekuyedza.

Chimwe chezvinhu zvinonyanya kukosha mu "vacuum filtration system" inoraswa ndeyekushanda kwe "filtration membranes" dzayo. Vashandisi vanogona kusarudza kubva pa "nylon", "PES", uye "hydrophilic PVDF/MCE/CA membranes", imwe neimwe yakagadzirirwa mashandisirwo ayo. Kuchinjika uku kunoita kuti vaongorori vagone kusarudza "membrane" yakakodzera zvinodiwa zvavo zvekusefa, kungave vari kushanda ne "cell culture media", "biofluids", kana mimwe mishonga yemvura.

Pamusoro pezvo, sisitimu iyi inopa saizi dzemaburi e0.22μm ne0.45μm kuti inyatsosefa. Saizi yemaburi e0.22μm yakakodzera kushandisa mushonga wekuuraya utachiona, nepo saizi yemaburi e0.45μm yakakodzera kushandisa sampuli. Kunyatsojeka uku kwakakosha pakuchengetedza kunaka kwezvinhu zvipenyu zvinonzwa.

Mukupedzisa, sisitimu yekusefa ye vacuum inoraswa chigadzirwa chitsva mumunda wekusefa murabhoritari. Dhizaini yayo iri nyore kushandisa, pamwe chete nesarudzo dzakasiyana-siyana dzesefa uye saizi dzemaburi, inoita kuti ive chishandiso chakakosha kune chero ani zvake anobata mvura yemuzvarirwo uye masero ekuchengetedza masero. Sezvo marabhoritari achiramba achitsvaga mhinduro dzinoshanda uye dzakavimbika, iyi sisitimu yekusefa yave sarudzo yekutanga kusangana nezvinodiwa netsvagiridzo yemazuva ano.

Mukushanda kwerabhoritari, kushanda zvakanaka uye kuchena ndizvo zvinonyanya kukosha. Masisitimu ekusefa evacuum anoraswa anopa mhinduro yakanaka uye itsva. Masisitimu aya akagadzirwa kuti aite kuti kusefa kuve nyore ukuwo achiona kuti masampuro anoramba akachena uye asina kusvibiswa.

Chinhu chikuru cheiyi sisitimu ifunnel yakasimba yepolystyrene ine dhizaini yemutsipa wepolyethylene kuti zvive nyore kubatanidza kune vacuum source. Iyi dhizaini haingobatsiri chete kushandisa asiwo inovimbisa kubatana kwakachengeteka, ichideredza njodzi yekubuda kwemvura panguva yekushanda. Sisitimu iyi inewo nzvimbo inobviswa yepolystyrene kuti iunganidzwe uye ichengeterwe zviri nyore masampuro akaseferwa. Sisitimu yekusefa inowanikwa mumhando dzakasiyana-siyana—150 ml, 250 ml, 500 ml, uye 1000 ml—kuti isangane nezvinodiwa zvakasiyana-siyana zverabhoritari uye mamiriro ekushandisa.

Chinhu chikuru chekushandisa nzira yekusefa vacuum inoraswa ndechekuti ine ma filter membranes akawanda. Vashandisi vanogona kusarudza kubva ku nylon, polyethersulfone (PES), uye hydrophilic polyvinylidene fluoride/microcapsule/cellulose acetate (PVDF/MCE/CA), imwe neimwe yakagadzirirwa zvinodiwa pakusefa. Kuchinjika uku kunobvumira vaongorori kusarudza membrane yakakodzera zvichienderana nehunhu hwemuenzaniso, ingave iri mvura kana organic solvent.

Uyezve, sisitimu iyi ine maburi maviri, 0.22 μm uye 0.45 μm, zvichiita kuti kunyangwe zvidimbu zvidiki zvikwanise kubviswa zvinobudirira. Kunyatsojeka uku kwakakosha mukushandiswa kwakadai se microbiology, uko kubviswa kwetsvina kunogona kukanganisa zvakanyanya mhedzisiro yekuyedza.

Muchidimbu, masisitimu ekusefa evacuum anoraswa inzira itsva yekuvandudza marabhoritari ari kutsvaga kushanda zvakanaka uye kuvimbika. Nekugadzirwa kwawo kuri nyore kushandisa, sarudzo dzinochinjika dzesimba, uye ma filter membranes emhando yepamusoro, ave chishandiso chakakosha kune vaongorori vari kuedza kuwana mwero wepamusoro wekuchena kwesampuro. Gamuchira ramangwana retekinoroji yekusefa uye vandudza maitiro ako emarabhoritari nemhinduro iyi itsva.
