2. DTE CAS 6892-68-8 ua tus neeg sawv cev tiv thaiv rau sulfhydryl pawg hauv kev soj ntsuam enzyme, purification protein, thiab electrophoresis daim ntawv thov uas tswj kev txo cov kev mob tseem ceeb.
3. Dithioerythritol yog ua hauj lwm raws li ib tug chiral resolving tus neeg saib xyuas nyob rau hauv stereochemical kev tshawb fawb thiab ua ib lub tsev thaiv nyob rau hauv lub synthesis ntawm thiol - muaj cov tebchaw .
4. Cov kws tshawb fawb siv DTE CAS 6892-68-8 ua lwm txoj hauv kev rau dithiothreitol (DTT) hauv cov ntawv thov uas xav tau cov khoom txo qis zoo sib xws tab sis muaj cov yam ntxwv sib txawv stereochemical.
Cia thiab ceev faj
1. Dithioerythritol yuav tsum tau muab cia rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw tsis muaj zog (nitrogen lossis argon) hauv qhov txias, qhuav, thiab zoo- qhov chaw cua, tiv thaiv lub teeb thiab noo noo.
2. Kev pom zoo khaws cia muaj xws li -20℃rau kev ruaj ntseg mus ntev (txog 3 xyoos) lossis 4℃txog li 2 xyoos; Cov kev daws teeb meem yuav tsum tau khaws cia ntawm -20℃txog li 1 lub hlis.
3. DTE CAS 6892-68-8 yog suav nrog GHS cov lus hais txog kev phom sij H302 (Hmob yog tias nqos), H315 (ua rau tawv nqaij khaus), H319 (Ua rau qhov muag khaus), thiab H335 (Tej zaum yuav ua rau ua pa ua pa), nrog cov lus ceeb toom "Ceeb toom".
4. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg- hnab looj tes tiv thaiv, tsom iav kev nyab xeeb nrog sab- cov ntaub thaiv npog, thiab cov khaub ncaws tiv thaiv thaum tuav cov khoom no, ua kom muaj cua txaus hauv chaw ua haujlwm.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, ua kom muaj cua txaus, thiab hnav cov khoom tiv thaiv tus kheej nrog rau cov tshuaj lom neeg - hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub tshuab nqus plua plav tsim nyog thaum Dithioerythritol tso tawm.
2. Sau DTE CAS 6892-68-8 los ntawm kev cheb lossis nqus tsev yam tsis tsim cov plua plav uas siv cov cuab yeej tsis ua kom tawg, thiab muab tso rau hauv cov thawv kaw tsim nyog rau kev pov tseg.
3. Tsis txhob tsim cov huab cua thaum lub sij hawm ntxuav kom tsis txhob ua pa; tiv thaiv cov khoom los ntawm kev nkag mus rau hauv cov dej ntws los yog cov chav dej.
4. Pov tseg cov ntaub ntawv khaws tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig los ntawm kev tso cai los ntawm kev puas tsuaj los yog kev tswj incineration.
Kev tiv thaiv hluav taws
1. Dithioerythritol tsis raug cais raws li cov nplaim hluav taws kub heev tab sis tuaj yeem decompose nyob rau hauv hluav taws kub, emitting fumes lom xws li carbon monoxide, carbon dioxide, thiab sulfur oxides.
2. Siv cov tshuaj tsuag dej, tshuaj qhuav hmoov, carbon dioxide, los yog cawv- ua npuas ncauj resistant los tua hluav taws nrog cov khoom; Tsis txhob siv lub dav hlau dej ncaj qha raws li DTE CAS 6892-68-8 tuaj yeem tawg cov khoom tawg.
3. Cov neeg tua hluav taws yuav tsum hnav nws tus kheej- muaj cov cuab yeej ua pa hauv siab- thov, MSHA/NIOSH tau pom zoo, thiab cov iav tiv thaiv tag nrho thaum tuav cov hluav taws kub Dithioerythritol vim muaj kev puas tsuaj rau cov pa roj uas tsim los ntawm thermal decomposition .
4. Thaum lub sij hawm combustion, tej zaum yuav emit irritant thiab toxic fumes; txav cov thawv los ntawm qhov chaw tua hluav taws yog tias muaj kev nyab xeeb ua li ntawd, thiab muaj cov hluav taws kub los tiv thaiv ib puag ncig.
