♦Ndemanga yake:

Posachedwapa, nkhani zachidule za "Kunena Kwamtengo Wapatali Kwa Otsuka Mabotolo" zadzutsa maganizo a anthu ambiri.Nkhaniyi ili motere:

Wochapira mabotolo kwakanthawi Akazi a Zhou, wamkazi, ali ndi zaka zopitilira 40.Analembedwa ntchito m'mwezi wa Meyi kwa miyezi ingapo ku labotale yomwe ili ndi bungwe loyesa lachitatu kumpoto kwa China.Akazi a Zhou ali ndi udindo woyeretsa zinthu zamagalasi monga test chubu, pipette, beaker ndi kapu yoyezera mu labotale.Pakutsuka, chifukwa cha kuwonongeka kwa mankhwala otsalira mu glassware, nkhope yake, manja ndi ziwalo zina za thupi zinavulala kwambiri.Mlanduwu wavomerezedwa ndi madipatimenti oyenera.

Akazi a Zhou adauza atolankhani kuti kasamalidwe ka mkati mwa labotale yomwe yangokhazikitsidwa kumene sinakhale yangwiro, ndipo sanalandire maphunziro okwanira asanayambe ntchito.Makamaka pochiza zinthu zotsalira za mankhwala pambuyo poyesera, iwo sanadziwitsidwe za mlingo woopsa wa reagents, zipangizo zotetezera ndi njira zotetezera.

Kuonjezera apo, ntchito yoyeretsa ziwiya mu labotaleyi imakhala yolemetsa kwambiri mkati mwa sabata, pamene ukhondo wa magalasi mu labotale umakhala wochuluka kwambiri.Komabe, zotsatira za kusamba m'manja nthawi zambiri zimalephera kukwaniritsa miyezo yokhazikika ya labotale, kotero ndiyenera kugwira ntchito nthawi yowonjezereka kuti ndikonzenso.

Akazi a Zhou chifukwa cha kuvulala kwa inductrial adawonetsa kuti satha kugwira ntchito pang'ono.Malinga ndi izi, ndikupempha labotale kuti ipereke ndalama zothandizira kuchipatala, ndalama zotayika za ntchito, ndalama zoyendera, ndi zina zotero, ndalama zokwana yuan zoposa 1 miliyoni.

M'malo mwake, pali ma reagents ambiri mu labotale omwe angayambitse kuwonongeka kwa thupi la munthu.Ngati labotale sitenga chitetezo chokwanira kwa ogwira ntchito ndikunyalanyaza kuyeretsa ziwiya za labotale, zitha kubweretsa zotsatira zoyipa monga kudziwitsa, kulumala ndi khansa kwa ogwira ntchito. Ogwira ntchito za labotale nthawi zambiri amakumana nawo.

♦Ma reagents oopsa omwe amapezeka m'ma laboratories

Hydrochloric acid.A madzi mandala opanda mtundu.Fungo lake ndi lamphamvu komanso lopweteka.High dzimbiri katundu.Ndipo moyikira hydrochloric acid (fuming hydrochloric acid) amatha kusokoneza chifunga cha asidi.Angathe kuwononga ziwalo za kupuma, maso, khungu ndi m'mimba.Titha kunena kuti minofu yaumunthu, komanso kuteteza kuvulaza kwa hydrochloric acid mu mawonekedwe a chifunga cha asidi.Kuphatikiza apo, asidi wa hydrochloric akasakanikirana ndi okosijeni (monga bleach sodium hypochlorite kapena potaziyamu permanganate), mpweya wapoizoni wa chlorine umapangidwa.

Formaldehyde.M'moyo watsiku ndi tsiku, nthawi zambiri ndimamva za "poizoni wa formaldehyde" wamkati.Mu ntchito yozindikira o-phenylphenol, formaldehyde idagwiritsidwa ntchito ngati organic extract;Nthawi zambiri amagwiritsidwa ntchito ngati gawo la mafoni pakuzindikira kolumikizana kwamadzimadzi chromatography. Kuphatikiza apo, amagwiritsidwa ntchito nthawi zambiri poyeretsa ma ion magwero pogwiritsa ntchito ma spectrometry.Mankhwalawa amakhudza kwambiri dongosolo lamanjenje lapakati, ali ndi kusankha kwapadera pa mitsempha ya optic ndi retina ndipo imayambitsa kusintha kwa ma pathological.Kungayambitse metabolic acidosis.

Chloroform (chloroform).Nthawi zambiri kumapangitsa maso, kupuma thirakiti, khungu ndi mucous nembanemba wa thupi la munthu.Monga carcinogen, chloroform ndi wakupha chiwindi ndi impso.Valani magolovesi ndi magalasi ndi ntchito mu fume hood.

(4) Acetic anhydride. Mu labotale pentachlorophenol kuzindikira, acetic anhydride amagwiritsidwa ntchito ngati reactant wapakatikati.

(5) Toluene.Mu labotale ya mabungwe oyesa zakudya ndi mankhwala, toluene amagwiritsidwa ntchito ngati chotsitsa cha organic kuti azindikire zotsalira za mankhwala. choledzeretsa kwambiri chapakati mantha dongosolo, ndipo nthawi yaitali mkulu ndende yake nthunzi pokoka zingachititse kwambiri magazi m`thupi, chifukwa mu magazi matenda.

(6) Formic acid: poizoni kwambiri komanso wowononga kwambiri minofu ya mucosal, thirakiti lapamwamba la kupuma, maso ndi khungu.

Kuonjezera apo, ma reagents monga benzoic acid ndi phenylethanol amakhalanso ndi zokhumudwitsa kwambiri.Pamene thupi la munthu limatulutsa, kumeza, kuyamwa kwa khungu kungayambitse kuwonongeka kwa ziwalo zowonekera za thupi.

Poganizira izi, ma reagents a labotale a poizoni si okhawo omwe atchulidwa pamwambapa, kotero kusungidwa kwawo ndi kugwiritsa ntchito kwawo kuyenera kutsatira mosamalitsa malamulo oyenerera. Makamaka, ogwira ntchito za labotale, kuphatikiza ogwira ntchito yoyeretsa, ayenera kukhala ndi chidziwitso chodziteteza komanso chitetezo cha ena, ndikukhazikitsa ntchito yoyambira yovala zida zodzitetezera monga magolovesi ndi magalasi.

Inde, sikovuta kudziwa pankhaniyi kuti kuyeretsa kwamanja kwa zombo zoyesera, makamaka zotengera zagalasi zomwe zili ndi poizoni, sizidzangowopseza chitetezo cha ogwira ntchito, komanso kuonjezera mtengo wa labotale, chifukwa choyenerera. mikangano, ndipo ngakhale kuwononga mbiri ndi chithunzi cha labotale.Chofunika kwambiri, kulondola kwa zotsatira za mayeso sikudzatsimikiziridwa ngati glassware sikugwirizana ndi mfundo zaukhondo.Izi ndi chifukwa chachikulu chomwe makina ochapira a Lab ndi makina ena a zipangizo amatchuka kwambiri m'ma laboratories amitundu yonse.

Kuyeretsa pamanja:

Mtengo wa madzi, magetsi ndi ntchito wakwera;

Zinthu zambiri zoletsa komanso zosalamulirika;

Zimakhudza kwambiri thanzi lathupi ndi malingaliro amunthu;

Hangzhou XPZ glassware washer:

Ukhondo ndi wotsimikizika;

Wanzeru standardized kuyeretsa, yosavuta ntchito;

Full process data traceability;

Mogwira kupulumutsa chuma kwa labotale;

Kuyeretsa ndi gawo lofunikira la chithandizo chopanda vuto cha reagent yapoizoni yotsalira. Chotsukira mbale cha Lab sichingateteze chitetezo ndi thanzi la ogwira ntchito moyeserera kwambiri, komanso kukwaniritsa cholinga cha kuyeretsa kwake kodalirika.Kuti mupindule kwakanthawi kwa labotale, ziyenera kukhala mwachangu momwe mungathere kuti mupeze chochapira chagalasi chodziwikiratu!
