Disposable screw thread tsika machubhu anoita basa rakakosha mukushanda kwarabhoritari.Kushandisa kwavo kwakarurama kwete chete zvinobudirira kudzivirira kusvibiswa kwemuenzaniso, kusvibiswa-kusvibiswa uye kurasikirwa kwemuenzaniso, asi zvakare kunovimbisa huchokwadi uye kuvimbika kwe data yekuedza. Naizvozvo, zvakakosha zvikuru kugona maitiro akamisikidzwa ekushanda kuti uve nechokwadi chemhando yekuyedza.

Iyi nhungamiro inoshanda kune maitiro ekushanda ekurasa screw thread tsika machubhu anoshandiswa musero tsika, microbiology kuyedza, kukiriniki kuyedzwa uye mamwe minda.

Kugadzirira usati washandisa

Kugadzirira kwakaringana kusati kwaedza inhanho yakakosha mukuona kuita kwakaringana kwekuraswa screw thread tsika machubhu. Chekutanga, kutendeseka kwekurongedza kwekunze kunoda kunyatsotariswa kune chero kuputsika kana kutadza chisimbiso, izvo zvakakosha kuchengetedza sterility yemachubhu. Machubhu akaputirwa zvakanaka anofanira kuchengetwa munzvimbo yakaoma, yakachena kudzivirira hunyoro kana kusvibiswa.

Sterilization mamiriro haafanire kufuratirwa. Disposable screw thread tsika machubhu anogadzirwa nevagadziri venguva dzose anowanzo itwa sterilized ne gamma irradiation kana ethylene oxide, uye pasuru yacho inofanirwa kuve neyakajeka sterilization chiratidzo uye zuva rekupera. Vashandi vemurabhoritari vanofanirwa kutarisa nzira yekuvharisa uye zuva rekupera kuti vaone kuti machubhu ari muchimiro chepamusoro chekushandiswa.

Izvi zvinotevera zvinhu zvinofanirwa kutariswa pakusarudza maitiro:

1. Kusarudzwa kwevhoriyamu: 15ml yakajairwa machubhu inogona kusarudzwa yezviyedzo zvenguva dzose, nepo 50ml saizi inokurudzirwa kune yakakura-tsika tsika.
2. Hunhu hwezvinhu: polypropylene zvinhu zvakakwirira tembiricha inodzivirira, yakakodzera kune yakanyanya tembiricha sterilization zvinodiwa; polystyrene zvinhu zviri pachena, zviri nyore kuona.
3. Zvinodiwa zvakakosha: Pakuedza kwakakosha, sekuchengetedza tembiricha yakaderera, unofanirwa kusarudza zvinhu zvinodzivirira tembiricha yakaderera.

Vashandi veLabhoritari vanofanirwa kusarudza iyo yakanyatsokodzera tsika chubhu modhi zvinoenderana neyakaodha mamiriro ekuyedza, vachifunga nezve centrifugal simba rinodiwa, kuenderana kwemakemikari uye zvimwe zvinhu. Zvinokurudzirwa kumisikidza nzira yekushanda yakajairwa yekusarudzwa kwezvinhu zvinoshandiswa murabhoritari kuti ive nechokwadi chekuenderana uye kuberekana kwekuyedza.

Nzira Yakarurama

1. Kusunungura

• Vhura machubhu etsika munzvimbo yakachena yekushanda kuti uone kuti hapana kusvibiswa kwekunze panguva yekushandiswa.
• Pfeka magirovhosi asina utachiona kana shandisa zvibatiso zvisina utachiona kubvisa machubhu paunenge uchisunungura kudzivirira kusangana kwakananga nenzvimbo dzakakomba.

2. Spiking operation

• Izvo zvinorambidzwa zvachose kubata madziro emukati emuorivhi kana chivharo chemukati chevharo panguva yekuzadza kudzivirira kuiswa kwezvinyorwa zvinosvibisa.
• Vhoriyamu inofanirwa kudzorwa paunenge uchiwedzera masampuli emvura uye haifanirwe kudarika iyo yakakwira chiyero kudzivirira kudururwa kana kusavharwa kuvharwa kwemasampuli panguva yekushanda.

3. Nzira yekuisa chisimbiso

• Iyo screw cap inofanirwa kusimbiswa mushure mekuwedzera sampuli kuti ive nechokwadi chisimbiso chakazara. Kuisa chisimbiso kunogona kusimbiswa nekuita zvinyoro nyoro kuti uone chero kuvuza.
• Chenjerera kune zvine mwero screwing simba kuti udzivise simba rakawandisa rinokonzeresa kupera kweshinda kana kudambuka, izvo zvinogona kukanganisa kushandiswa zvakare kana kuvhara mhedzisiro.

4. Kumaka uye kurekodha

• Shandisa solvent-resistant, waterproof, peel-resistant label label kana mamaki kuti unyore nemazvo ruzivo rwemuenzaniso panzvimbo dzakachena, dzakaoma dzechubhu.
• Dzivisa kushandisa zvakajairika label bepa kana ingi zvinyoreso zvinotapukirwa nemwando kupera kudzivirira kurasikirwa ruzivo panguva yekuchengetedza.

Kungwarira Pakushandisa

1. Kudzivisa kusvibiswa

• Mashandiro ekuyedza anofanirwa kuitwa munzvimbo yakachena, isina guruva, mubhenji rakachena kana biological security cabinet inokurudzirwa.
• Deredza nguva yekusunungura machubhu etsika, uye oparesheni inofanirwa kukurumidza uye yakamisikidzwa kuderedza njodzi yekufumurwa.
• Machubhu akazvimirira etsika anofanirwa kushandiswa kune yega yega mhando yemasampuli, uye kusanganisa kunorambidzwa zvachose kudzivirira kusvibiswa kwemuchinjiko uye kukanganisa nemhedzisiro yekuyedza.

2. Centrifugation uye kuchengetedza

• Pamberi pe centrifugation, iva nechokwadi chekuita kuti screw cap yakavharwa zvakasimba kudzivirira sampuli kubva pakudonha; itawo yakanaka symmetrical leveling mucentrifuge kudzivirira kusaenzana kwemuchina.
• Paunenge uchichengeta, machubhu anofanirwa kuiswa panzvimbo yakatwasuka kudzivirira kubuda kunokonzerwa nekuiswa kwakachinjika. Dzivisa kuisa machubhu mukupisa kwepamusoro, chiedza chakajeka kana mhepo yakanyorova kuti urege kukanganisa kugadzikana kwemasampuli uye kushanda kwemachubhu.

3. Yakakosha sampuli kubata

• Kune sampuli dzine zvinoputika, organic zvinonyungudutsa kana zvinhu zvinoparadza zvakanyanya, modhi yakasarudzika inopikisa makemikari inofanira kushandiswa.
• Nokuda kwekudzivirira, shandisa cryopreservation tubes inopesana nekupisa kwakadzika; machubhu akajairika anogona kuraswa anogona kuita brittle kana kudonha patembiricha yakadzikira.

Zvaunofanira Kuita Mushure mekushandisa

1. Biosafety processing

• Machubhu etsika ane utachiona, angangoita pathogenic kana ane njodzi yakanyanya biological samples anofanirwa kuve akavharirwa kana kuvharwa nemishonga inouraya utachiona hunoenderana nerabhoritari biosafety level zvinodiwa isati yaraswa semarara.
• Machubhu emararamiro akaraswa anofanirwa kuiswa mubhini rakasarudzwa remarara re "bio-cotaminated plastic" maererano nerabhoritari ine njodzi yekuronga marara uye masystem system, uye haifanirwe kusanganiswa nemarara anoraswa.

2. Mazano ezvakatipoteredza

• Koshesa machubhu etsika akagadzirwa nezvinhu zvinogona kushandiswazve uye kutora chikamu muchirongwa chepakati chekudzokorodza uye kuraswa kwezvakatipoteredza kune zvinodyiwa mumarabhoritari kana mamiriro achibvumidza.
• Deredza kupambadza kusingakoshi kwezvinhu zvinodyiwa, tsigira kushandiswa zvine musoro kwezvinhu zvinoraswa pasi pemamiriro ekuchengetedza, uye kukurudzira kuvakwa kwegirinhi marabhoritari.

Mibvunzo Inowanzo bvunzwa

1. Chii chandinofanira kuita kana ndisingakwanisi kusimbisa screw-in cap?

Chekutanga tarisa kuti shinda dzakanyatsoenderana here uye kuti hapana zvinhu zvekunze zvakanamira mushinda dzacho. Usamanikidzire tambo kuti dzisunungure sezvo izvi zvinogona kukanganisa muromo kana chivharo. Kana ichiri kukundikana kuvhara, tsika tube inofanira kutsiviwa neimwe itsva.

2. Machubhu etsika anoraswa anogona kushandiswazve here?

Kudzokorora kushandiswa hakukurudzirwi. Kuiswa chisimbiso uye kusachena kwemachubhu anoraswa hakuzovimbiswe mushure mekushandiswa, uye kushandiswazve kunogona kukonzera kusvibiswa, mhedzisiro, kana kukuvara kwechubhu.

3. Chii chandinofanira kuita kana ndine mvura inobuda pacentrifuging?

Tarisa kuti chivharo chakavharwa zvakasimba uye chinonamira zvakanaka, uye ona kuti machubhu etsika akaiswa zvakanaka pamberi pe centrifugation. Regedza kushandisa kupfuura iyo yakanyanya centrifugal kumhanya uko machubhu anogadziriswa. Kana zvichidikanwa, sarudza yakasarudzika-inodzivirira centrifuge chubhu seimwe nzira.

Mhedziso

Iko kushandiswa kwakamisikidzwa kwekuraswa screw thread tsika machubhu inhanho yakakosha kuve nechokwadi chechokwadi chemhedzisiro yekuyedza, chengetedzo yemuenzaniso uye kuvimbika kwekushanda. Kuomerera kwakasimba kumaitiro ekushanda uye biosafety zvinodiwa, kungave mukuunganidzwa kwemuenzaniso, kubata, kuchengetwa kana kuraswa, ndiyo vimbiso yekutanga yekuvandudza hunhu hwekuyedza uye kuderedza njodzi.

Zvinokurudzirwa kuti maLab matekiniki ashandise emhando yepamusoro tsika machubhu ane chisimbiso chakanaka, makemikari kuramba uye inoshanda tembiricha yemhando zvinoenderana nezvavanoda kuyedza, kuitira kuvandudza kugona kwekuyedza uye kuona kutungamira kwakasimba kwezviwanikwa zverabhoritari.
