Kodichotsukira magalasi chodzichitira chokha m'ma laboratories"wothandizira" kapena "msonkho wa IQ"? Tinapempha woyesa labu kuti agawane zomwe adakumana nazo ndikuwona zomwe anganene.

Malingaliro a oyang'anira ma laboratori m'mabungwe oyesa chakudya:

Tinkachita zoyeserera zowunikira, ndipo chinthu chomwe chinatikhumudwitsa kwambiri chinali kuyeretsa mabotolo. Tikachita zowunikira zakudya, timapeza zinthu zambiri zoopsa monga nitrite ndi zotsalira za mankhwala ophera tizilombo m'zakudya. Laboratory ikatha, mapaipi ogwiritsidwa ntchito, ma beakers ndi ziwiya zina ziyenera kutsukidwa pamanja. Nthawi zambiri pamakhala mabotolo okhala ndi madontho ambiri amafuta omwe ndi ovuta kuwayeretsa, ndipo amatsukidwa ndi madzi oyera ambiri ndi madzi apampopi pakapita nthawi, koma amakhalabe osayera mokwanira. Ndipo nthawi zambiri timakhala otanganidwa kwambiri kuntchito, kotero timangopeza nthawi yogwira ntchito nthawi yowonjezera ndikugona mochedwa kuti tithane ndi mabotolo ovutawa.

Pambuyo powonjezeramakina ochapira mabotolo odzipangira okha m'botolokuchokera ku labotale yathu, zathetsa vuto lalikulu kwa ife. Nthawi zambiri timatsuka mabotolo ndi manja kwa maola pafupifupi 5, ndipomakina ochapira mabotoloakhoza kuzitsuka mu mphindi 45. Zipangizozi zili ndi makina owumitsa, ndipo mabotolo otsukidwa ndi ofanana ndi atsopano. Makinawa ali ndi mitundu yambiri ya mapulogalamu oyeretsera omwe angasankhidwe momasuka, ndipo palinso mapulogalamu ambiri oyeretsera omwe amasinthidwa mwamakonda. Chotsukira chapadera chomwe chimagwiritsidwa ntchito ndi yankho lokhazikika, ndipo mlingo wake ndi 5-10ML nthawi iliyonse.

Ndipo modabwitsa, titagwiritsa ntchito, tinapeza kuti sikuti imangomwa madzi okha, komanso kutipulumutsa madzi ambiri. Posamba ndi manja, ndimaopa kuti sizikhala zoyera mokwanira kuti zikhudze zotsatira za kuyesaku, kotero ndimatsegula pompo kuti nditsuke botolo mwamphamvu, ndipo zambiri zimatsukidwa, zomwe zingawononge madzi ambiri. Ndi botolomakina ochapira, kuchuluka kwa madzi kumatha kulamulidwa mu ulalo uliwonse, ndipo mtengo wa madzi a labotale ndi wotsika kwambiri kuposa kale.

Kudzera mu kugawana kwa oyesera omwe atchulidwa pamwambapa, titha kuwona kuti makina ochapira mabotolo sangangoyeretsa ziwiya zoyesera mwachangu komanso bwino, komanso amasunga madzi. Kodi amachita bwanji izi? Tiyeni tiwone njira yotsukira pansipa kuti timvetse.

Kutsuka makina ochapira okha a labotale yopopera:

1. Kutsuka musanagwiritse ntchito: choyamba gwiritsani ntchito madzi apampopi kamodzi, ndipo gwiritsani ntchito mkono wopopera kuti mutsuke chotsukira chozungulira mwamphamvu kuti mutsuke zotsalira mu botolo ndi mtsuko, ndikutulutsa madzi odetsedwa mukatha kutsuka. (Ma laboratories okhala ndi zofunikira angagwiritse ntchito madzi oyera m'malo mwa madzi apampopi)

2. Kuyeretsa kwakukulu: Lowetsani madzi apampopi kachiwiri, kuyeretsa kotenthetsera (kosinthika mu mayunitsi a 1°C, kosinthika kufika pa 93°C), chipangizocho chimawonjezera chotsukira cha alkaline chokha, ndipo chimapitiriza kutsuka mabotolo ndi mbale pogwiritsa ntchito mphamvu yamagetsi. Tsukani madzi odetsedwa mukatha kutsuka.

3. Kuyeretsa ndi kuyeretsa: Lowani m'madzi apampopi kachitatu, kutentha koyeretsa ndi pafupifupi 45°C, zidazo zimawonjezera asidi woyeretsera zokha, ndipo zimapitiriza kutsuka mabotolo ndi mbale ndi mphamvu yayikulu kudzera mu chopopera, ndikutulutsa madzi odetsedwa mutatsuka.

4. Kutsuka: Pali nthawi zitatu zotsuka zonse pamodzi;

(1) Lowetsani madzi a m'popi, sankhani chotsukira chotenthetsera;

(2) Lowetsani madzi oyera, sankhani chotsukira chotenthetsera;

(3) Lowetsani madzi oyera kuti mutsuke, sankhani chotenthetsera; kutentha kwa madzi kungathe kuyikidwa pa 93°C, nthawi zambiri pafupifupi 75°C kumalimbikitsidwa.

5. Kuumitsa: Mabotolo otsukidwa amaumitsa mwachangu komanso mwaukhondo mkati ndi kunja kwa chidebecho panthawi yotenthetsera, kupumira nthunzi, kuzizira, ndi kutulutsa madzi, pamene akupewa kuipitsa madzi pambuyo poyeretsa.

Zachidziwikire, njira yoyeretsera yomwe ili pamwambapa ndi njira yachizolowezi. Makina ochapira amatha kusankha pulogalamu yoyeretsera malinga ndi zosowa za zipangizo za labotale. Njira yonse ya zida imayeretsedwa yokha, ndipo zida zikayamba ntchito yoyeretsa, palibe wogwira ntchito amene amafunika kuchita ntchito iliyonse.

Mwachidule, makina ochapira mabotolo odzipangira okha m'ma laboratories ndi othandiza kwambiri pa labotale yathu, ndichifukwa chake ma labotale ambiri tsopano ali ndi zida izi.
