Papa II Type A2/B2 Keena Palekana Ola

ʻO ke keʻena palekana olaola (BSC) he ʻano pahu hoʻomaʻemaʻe ea ʻino ka mea hiki ke hoʻōki i kekahi mau mea ola kino e hoʻopōʻino mai ka ea ʻana i ka wā o nā hana hoʻokolohua.Ma nā ʻāpana o ka microbiology, biomedicine, genetic engineering, a me ka hana ʻana i nā huahana biological, hoʻohana nui ʻia i ka noiʻi ʻepekema, aʻo ʻana, ka nānā ʻana i ke kino, a me ka hana ʻana.ʻO ia ka ʻāpana koʻikoʻi o ka pale pale palekana i loko o ka hale hana biosafety pale pale pae mua.

ʻO ka hana ʻoihana mālama ola kino:

ʻO ka kānana ea ʻāpana kiʻekiʻe (HEPA) i ka ea o waho e kānana i ka ea o waho, ʻo ia ke ʻano o ka hana ʻana o ke keʻena palekana olaola.Mālama ʻo ia i ke kaomi maikaʻi ʻole i loko o ke keʻena keʻena a hoʻohana i ka ea ea kū i ka pale i nā limahana.Eia hou, pono e kānana ʻia ka ea o ke keʻena e ka kānana HEPA a laila hoʻokuʻu ʻia i ka lewa no ka pale ʻana i ke kaiapuni.

Nā loina no ke koho ʻana i nā keʻena palekana olaola i loko o nā laboratories biosafety:

ʻAʻole pono pinepine ka hoʻohana ʻana i kahi keʻena palekana olaola a i ʻole ke keʻena palekana olaola papa I inā he 1 ke kiʻekiʻe o ke keʻena hana.i ka pae ʻana o ke keʻena hana i ka Papa 2, hiki ke hoʻohana ʻia kahi keʻena palekana olaola Papa I i ka wā e hiki mai ai ka microbial aerosol a i ʻole nā ​​hana splashing;Pono e hoʻohana ʻia nā keʻena palekana olaola o ka papa II-B piha (Type B2) i ka wā e hana ana me nā carcinogens kemika, nā mea radioactive, a me nā mea hoʻoheheʻe.Pono e ho'ohana 'ia ka papa II-B (Type B2) a i 'ole ka Papa III no nā ka'ina hana e pili ana i nā mea ma'i ma'i ke pae 3 ka pae ho'okolohua. pae 4. Ke komo nā limahana i nā lako pale puʻe maikaʻi, hiki ke hoʻohana ʻia nā keʻena palekana biological Class II-B.

Keena Palekana Olas (BSC), i kapa ʻia ʻo Biological Safety Cabinets, hāʻawi i nā limahana, nā huahana, a me ka pale kaiapuni ma o ka ea laminar a me ka kānana HEPA no ka lab biomedical/microbiological.

ʻElua mau ʻāpana nā keʻena palekana olaola: he kino pahu a me kahi pale.ʻO ke kino pahu ka nui o nā hale i lalo:

1. Pūnaehana kānana ea

ʻO ka ʻōnaehana koʻikoʻi no ka hōʻoia ʻana i ka hana o kēia mea hana ʻo ia ka ʻōnaehana kānana ea.Hana ʻia ia me kahi kānana ea hoʻopau waho, ka peʻahi hoʻokele, kahi ʻea ea, a me nā kānana ea ʻehā.ʻO kāna kumu nui, ʻo ia ka lawe mau ʻana i ka ea maʻemaʻe, me ka hōʻoia ʻana ʻaʻole i emi iho ka nui o ke kahe ʻana o ka wahi hana (vertical airflow) ma mua o 0.3 m/s a ʻo ka pae maʻemaʻe e hōʻoia ʻia he 100 mau māka.I mea e pale aku ai i ka haumia o ke kaiapuni, hoʻomaʻemaʻe pū ʻia ke kahe o waho i ka manawa like.

ʻO ka kānana HEPA ka ʻāpana hana nui o ka ʻōnaehana.Hana ʻia kona kiʻi i kahi mea ahi kū hoʻokahi, a ua hoʻokaʻawale ʻia nā ʻāpana alumini corrugated i loko o nā grids.Hoʻopiha ʻia kēia mau grids me ka emulsified aniani fiber sub-particles, a hiki i ka pono o ka kānana ke hiki i 99.99% a 100%.ʻO ka kānana mua ʻana a me ka hoʻomaʻemaʻe ʻana i ka ea ma mua o kona komo ʻana i ka kānana HEPA e hiki ke hana ʻia e ka uhi kānana mua a i ʻole kānana mua i ka hoʻokomo ʻana i ka ea, hiki ke hoʻonui i ke ola o ka kānana HEPA.

2. Pūnaehana pahu ea exhaust waho

ʻO ka ʻōnaehana pahu hoʻoheheʻe waho i hana ʻia me kahi pahu hoʻoheheʻe, kahi peʻa, a me kahi pahu pahu pahu waho.No ka mālama ʻana i nā laʻana a me nā mea hoʻokolohua i loko o ke keʻena keʻena, lawe ka peʻahi hoʻoheheʻe waho i ka ea lepo mai ka lumi hana me ke kōkua o kahi kānana hoʻopau waho.No ka mālama ʻana i ka mea hoʻohana, ʻae ʻia ka ea ma ka wahi hana e haʻalele.

3. Sliding mua puka makani nenoaiu

Hoʻokumu ʻia ka ʻōnaehana hoʻokele puka aniani mua me ka puka aniani mua, ka mīkini puka, ka mīkini traction, ke kumu hoʻoili a me ka hoʻololi palena.

4. Aia ke kumu kukui a me ke kumu kukui UV ma loko o ka puka aniani e hōʻoia i kekahi olinolino i loko o ka lumi hana a me ka sterilize i ka papaʻaina a me ka ea i loko o ka lumi hana.

5. Aia i ka papa hoʻomalu nā mea hana e like me ka mana, ke kukui ultraviolet, ke kukui kukui, ka hoʻololi fan, a me ka hoʻomaluʻana i ka neʻeʻana o ka puka aniani mua.ʻO ka hana nui ka hoʻonohonoho a hōʻike i ke kūlana ʻōnaehana.

Papa II A2 keena palekana olaola/keena palekana olaola na mea nui o ka hale hana:1. Ea pale kaawale manao pale i loko a me waho kea-contamination, 30% o ka ea kahe i hoʻokuʻu 'ia ma waho a me 70% o ka loko circulation, kino kaomi vertical laminar kahe, aole pono e kau paipu.

2. Hiki ke wehe ʻia ka puka aniani a pani ʻia no ka sterilization, a me nā hōʻailona hoʻokiʻekiʻe kau palena.Hiki ke hoʻololi ʻia i luna a i lalo a waiho ʻia ma nā wahi āpau.3.No ka maʻalahi o ka mea hoʻohana, ua hoʻokomo ʻia ke kumu hoʻopuka mana ma ka wahi hana me kahi kumu wai ʻole a me kahi hoʻokaʻawale wai.4.No ka ho'ēmiʻana i ka hoʻohaumiaʻana, ua hoʻokomoʻia kahi kānana kiko'ī ma ka ea hoʻopau.5.Hana ʻia ka papa hana me ke kila kila kila 304 maikaʻi ʻole, ʻoluʻolu, a me ka ʻole o nā hopena make.Hiki iā ia ke ho'ōki i nā pūhui erosive a me nā disinfectants mai ka ʻānai ʻana a maʻalahi hoʻi e disinfect piha.6.Hoʻohana ia i ka mana o ka panel LCD LED a me ka mea pale kukui UV i kūkulu ʻia, hiki ke wehe wale ʻia ke pani ʻia ka puka palekana.7.Me ke awa ʻike DOP, i kūkulu ʻia i loko o ka ʻokoʻa kaomi gauge.8, 10° tilt angle, e like me ka manaʻo hoʻolālā kino kanaka.
