Kusefera kwa Vacuum Kotayika

1. Dongosololi lili ndi funnel ya polystyrene yokhala ndi khosi la polyethylene ndi botolo losungiramo polystyrene lochotseka.
2. Mavoliyumu (ml): 150,250,500 ndi 1000.
3. Ma membrane osefera: Nayiloni, PES, Hydrophilic PVDF/MCE/CA.
4. Kukula kwa Mabowo (μm): 0.22 ndi 0.45.
5. Amagwiritsidwa ntchito kwambiri posefa ndi kusunga zinthu zachikhalidwe cha maselo, madzi achilengedwe, ndi njira zina zamadzimadzi.

**Mutu: Tsogolo la Kusefa: Kufufuza Machitidwe Osefa Otayidwa a Vacuum**

Pa kafukufuku wa m'ma laboratories ndi bioprocessing, kugwira ntchito bwino komanso kudalirika n'kofunika kwambiri. Makina osefera a vacuum omwe amatayidwa ndi njira yotchuka komanso yatsopano. Makinawa adapangidwa kuti azitha kusefera mosavuta, ndipo akhala chida chofunikira kwa ofufuza ndi asayansi.

Pakatikati pa dongosololi ndi funnel ya polystyrene yokhala ndi khosi la polyethylene, zomwe zimatsimikizira kulumikizana kotetezeka komanso kosataya madzi. Botolo losungiramo polystyrene lochotseka limapangitsa kuti zikhale zosavuta kusonkhanitsa ndikusunga zitsanzo zosefedwa, zomwe zimapangitsa kuti zikhale zosankha zabwino kwambiri m'ma laboratories otanganidwa. Dongosololi likupezeka m'malo osiyanasiyana - 150ml, 250ml, 500ml ndi 1000ml - kuti likwaniritse zosowa zosiyanasiyana zoyesera.

Chimodzi mwa zinthu zodabwitsa za makina osefera a vacuum omwe amatayidwa ndi kusinthasintha kwa ma nembanemba ake osefera. Ogwiritsa ntchito amatha kusankha kuchokera ku nayiloni, PES, ndi ma nembanemba a PVDF/MCE/CA okonda madzi, chilichonse chopangidwa kuti chigwiritsidwe ntchito mwanjira inayake. Kusinthasintha kumeneku kumatsimikizira kuti ofufuza amatha kusankha nembanemba yoyenera kwambiri pazofunikira zawo zosefera, kaya akugwira ntchito ndi ma cell culture media, biofluids, kapena njira zina zamadzi.

Kuphatikiza apo, dongosololi limapereka kukula kwa ma pore a 0.22μm ndi 0.45μm kuti asefedwe molondola. Kukula kwa ma pore a 0.22μm ndi koyenera poyezera njira zoyeretsera, pomwe kukula kwa ma pore a 0.45μm ndi koyenera poyezera zitsanzo. Kulondola kumeneku ndikofunikira kwambiri kuti zinthu zachilengedwe zikhale zotetezeka.

Pomaliza, makina osefera a vacuum omwe amatayidwa ndi chinthu chatsopano kwambiri pankhani yosefera m'ma laboratories. Kapangidwe kake kosavuta kugwiritsa ntchito, kuphatikiza mitundu yosiyanasiyana ya zosefera ndi kukula kwa ma pore, kumapangitsa kuti ikhale chida chofunikira kwambiri kwa aliyense amene amagwiritsa ntchito madzi achilengedwe komanso zinthu zosungira maselo. Pamene ma laboratories akupitiliza kufunafuna mayankho ogwira mtima komanso odalirika, makina osefera awa akhala chisankho choyamba kukwaniritsa zosowa za kafukufuku wamakono.

Mutu wa Blog: Tsogolo la Ukadaulo Wosefera: Kufufuza Machitidwe Osefera Otayidwa mu Vacuum

Mu ntchito za mu labotale, kuchita bwino ndi ukhondo ndizofunikira kwambiri. Makina osefera a vacuum omwe amatha kugwiritsidwa ntchito nthawi imodzi amapereka njira yabwino komanso yatsopano. Makina awa adapangidwa kuti azitha kusefera mosavuta komanso kuonetsetsa kuti zitsanzo zimakhalabe zoyera komanso zopanda kuipitsidwa.

Gawo lalikulu la dongosololi ndi funnel yolimba ya polystyrene yokhala ndi kapangidwe ka khosi la polyethylene kuti igwirizane mosavuta ndi gwero la vacuum. Kapangidwe kameneka sikuti kamangowonjezera kugwiritsa ntchito mosavuta komanso kumathandizira kulumikizana kotetezeka, kuchepetsa chiopsezo cha kutuluka kwa madzi panthawi yogwira ntchito. Dongosololi lilinso ndi chosungira cha polystyrene chochotseka kuti chizitha kusonkhanitsa ndi kusungira zitsanzo zosefedwa mosavuta. Dongosolo losefera limapezeka m'njira zosiyanasiyana—150 ml, 250 ml, 500 ml, ndi 1000 ml—kuti likwaniritse zosowa zosiyanasiyana za labotale komanso zochitika zogwiritsira ntchito.

Ubwino waukulu wa makina osefera a vacuum omwe amagwiritsidwa ntchito nthawi imodzi ndi kusankha kwake kwakukulu kwa ma filter nembanemba. Ogwiritsa ntchito amatha kusankha kuchokera ku nayiloni, polyethersulfone (PES), ndi hydrophilic polyvinylidene fluoride/microcapsule/cellulose acetate (PVDF/MCE/CA), iliyonse yopangidwira zosowa zinazake zosefera. Kusinthasintha kumeneku kumalola ofufuza kusankha membrane yoyenera kwambiri kutengera mawonekedwe a chitsanzocho, kaya ndi yankho lamadzi kapena organic solvent.

Kuphatikiza apo, dongosololi limapereka ma pore awiri, 0.22 μm ndi 0.45 μm, zomwe zimaonetsetsa kuti ngakhale tinthu tating'onoting'ono kwambiri titha kuchotsedwa bwino. Kulondola kumeneku ndikofunikira kwambiri pakugwiritsa ntchito monga microbiology, komwe kuchotsa zinthu zodetsa kungakhudze kwambiri zotsatira za kafukufuku.

Mwachidule, makina osefera a vacuum omwe amatayidwa ndi njira yatsopano yopangira ma laboratories omwe akufuna kugwira ntchito bwino komanso kudalirika. Ndi kapangidwe kake kosavuta kugwiritsa ntchito, njira zosinthira mphamvu, komanso ma filter nembanemba apamwamba kwambiri, akhala chida chofunikira kwambiri kwa ofufuza omwe akuyesetsa kukwaniritsa miyezo yapamwamba kwambiri ya kuyera kwa zitsanzo. Landirani tsogolo la ukadaulo wosefera ndikuwonjezera njira zanu za laboratories ndi yankho latsopanoli.
