Trimethylol aminomethane
Shandisa
① Iyo yepakati yefosfomycin, inogona zvakare kushandiswa sevulcanization accelerator, cosmetics (kirimu, lotion), mineral oil, parafini emulsifier, biological buffer.
② Inoshandiswa seasidhi gasi inonwisa, kugadzirira kwebuffer, surfactant, emulsifier uye accelerator.Inoshandiswawo mune organic synthes.
Kugadzira Nzira
Dissolve Tris nemvura shoma inopfungaira kaviri (300-500ml), wedzera HCl, gadzirisa pH kusvika 7.6 neHCl (1N) kana NaOH (1N), uye pakupedzisira wowedzera mvura inopisa kaviri ku1000ml.Mvura iyi ndiyo inochengeterwa mvura, yakachengetwa mufiriji pa4 ℃.
Cherechedza: Huwandu hwePH hweTris-Hcl hunosiyana netembiricha, saka inofanirwa kuyerwa patembiricha yekamuri, saka mibairo yakayerwa inovimbika.
Buffering character
Tris inzvimbo isina kusimba ine pKa ye8.1 pakamuri tembiricha (25 ℃).Zvinoenderana neiyo buffering theory, iyo inoshanda buffering yeTris buffers iri pakati pepH7.0 ne9.2.
Iyo pH yeaqueous solution yeTris base ingangoita 10.5, uye iyo buffer ye pH kukosha inogona kuwanikwa nekuwedzera hydrochloric acid kugadzirisa iyo pH kukosha kune yaunoda kukosha.Nekudaro, kutarisisa kunofanirwa kubhadharwa kune pesvedzero yekushisa pane pKa yeTris.Dhigirii, PH kukosha kwakadzikira ne0.03.
1M Tris-HCl 6.8 uye 1.5M Tris-HCl 8.8 ndiwo anonyanya kushandiswa reagents eSDS-PEJI.
Nepo TAE, TBE nemamwe mareagents akagadzirwa kubva kuTris ari iwo anonyanya kushandiswa reagents eDNA electrophoresis, TE (pH8.0) inonyanya kushandiswa pakuparara kweDNA.(TE iri Tris pamwe neEDTA.)
Tris buffers haingo shandiswa zvakanyanya sezvinonyungudutsa zve nucleic acids uye mapuroteni, asiwo ane zvakawanda zvakakosha zvekushandisa.Tris inoshandiswa kuprotein crystal kukura pasi pemamiriro akasiyana epH.Iyo yakaderera ionic simba reTris buffer inogona kushandiswa pakugadzira mafiber epakati elamin muC. elegans.Tris zvakare chimwe chezvikamu zvikuru zveprotein electrophoresis buffers.Pamusoro pezvo, Tris ndeyepakati mukugadzirira kwevano surfactants, vulcanization accelerators, uye mimwe mishonga.Tris inoshandiswawo seyero yetitration.
Muchimiro chemifananidzo uye zvinyorwa, zvinogona kusanganisira ruzivo rwechigadzirwa, masevhisi uye zvakanakira.Inogona kudarika chigadzirwa kuwedzera zvimwe zvemukati (zvinonetsa mutengi, zvinonetsa, nezvimwe), kuchengetedza kwezvakatipoteredza, emahara masampuli, nezvimwe.
1. Samples inoedzwa mahara kuti ive nechokwadi chekushandisa kwakajairika kwevatengi.
2. Maererano nezvinodiwa nevatengi vakasiyana-siyana, zviduku kusvika ku100g, zvakakura kusvika matani emabhodhoro, zvinogona kusangana nezvinodiwa zvekuputira.
3. Flexible kubhadhara mazwi, telegraphic kutumira kana kubvuma (kusangana nezvinodiwa zvekugamuchira)
4. Kufambisa kwekukurumidza, zuva rimwe chete kana zuva rinotevera rinogona kuendeswa, iyo yose nzira yekutevera ruzivo rwekugadzirisa zvinhu, kuve nechokwadi chekushandiswa nenguva kwevatengi.
5. Yakanakisa mushure mekutengesa sevhisi, kushivirira uye kungwarira kugadzirisa marudzi ese ezvinetso zvinogona kuitika, senge matambudziko emhando, kushandira pamwe nevatengi kuti vashingaire kubata nazvo, usanzvenga mutoro uye kungopindura.
6. Chikwata chakanakisisa, kushanda kwakanaka kwekushanda uye ruzivo rwemhizha inoita kuti vatengi vasazorore chete pamusoro pezvigadzirwa zvedu, asiwo vanonzwa kuti boka redu rakavimbika.
7. Kuzvimiririra kunze kwenyika kodzero yekuvaka musika wepasi rose uye yepasi rose brand pesvedzero.
8. Kutendeseka, tsamba yakavakirwa, makore makumi maviri enhoroondo yekambani uye mukurumbira wakanaka, rega vatengi vasununguke, mutual kubatsirwa uye kukunda-kuhwina, kutendeseka kubatana.
