Yini tripod, kudivayisi isicelo yayo kanye

belulekwa ukufunda imibuzo ngaphambi kokuvakashela i-chemistry isifundo tripod futhi uyini. Isetshenziselwa ukusekela umnikazi ama, amathuluzi, kanye namanye amadivayisi. Material ngoba esikhethwe heavy metal kuya ebhasikidini akuyona lehla kwalo ngemva ukulungisa isitsha ketshezi.

Kungani yokubeka?

Uma sicabanga ukuthi tripod injongo eyinhloko ukusetshenziswa kwalo - elibambe static futhi evikelekile lezinto. Ububanzi Yokusebenzisa adala ebanzi. Ngaphezu elabhorethri ingasetshenziswa izinjongo ukukhiqizwa.

Okusho tripod ithole isicelo emsebenzini wokukhiqiza izithombe. A tripod noma owodwa yokubeka isetshenziselwa ukubeka phezu kwalo lens noma flash. Kukhona onobuhle nezinamathiselo amaningi, ngezinye izikhathi esiyingqayizivele. Ngenxa yaleli lungiselelo, isithombe se-engela ezithile, futhi ngaphandle ukufiphala.

Ngo-chemistry imithi tripod kuyasiza hang umfuma Ukushisa yayo. Ngokuvamile ezikhumulweni ahlelwe amashubhu ukuthi akukwazi thwi. A sebuningini emalungeni detachable Ungasetha ngokunembile isikhundla oyifunayo emkhathini.

izici kudivayisi

Sinikeza incazelo kuyini tripod:

• Idivayisi ye asizayo imishini laboratory isetshenziswa ukubamba izitsha kanye nezitsha.
• Igama elithi "States" lisetshenziswa ukuze libhekisele kumuntu ukwesekwa yenethiwekhi lapho kukhona ziboshelwe Ukugunda noma izibopho.
• Tripod libhekene nokubopha izakhi ukuze elawula izimpiko clamping thwi kanye nendawo.
• Ngokuvamile umklamo evundla mpo. Uhlobo lokuqala ngokuyinhloko asetshenziswa ukuze ihlanganise amashubhu. Ngo ilungiselelo elinjalo kusiza umsebenzi nge imishini laboratory.

okufushane Kuqondile has a isisindo ngesisekelo ipuleti lensimbi ezinkulu, kulo yokubeka metal. It is kakade exhunywe imilenze ngocingo.

Uyini kudivayisi?

Ukuze uqonde ukuthi tripod, kufanele uzijwayeze izingxenye zalo. Kumila ngokuvamile enziwa cast iron. Kuyinto enzima futhi akavumi ukuba iwe yokubeka. isisindo salo kushintshwe for the esiphezulu esitsheni kungenzeka egcwele uketshezi. Ukukhetha umthwalo okungalungile Ungabeka umkhiqizo bese ngishiswa zamakhemikhali.

Ukuze iziqobosho flasks, ukuhlolwa amashubhu nezinye izinto laboratory okufana ovundlile ukubulawa tripod ingasetshenziswa lezisekelo ezimbili, uprights nenduku yokuguquguqula ngesimo uhlamvu P. It kuvela ukubeka inani elikhulu kumadivayisi edingekayo nsuku zonke.

Ukuze ukusebenza inqwaba amashubhu akhethiwe owodwa esigabeni tripods noma embhedeni nge isizinda esindayo, ukuze kuncishiswe ingozi tipping ukufakwa. Wonke amaseli abe inamba engafani eyaziswa lula wokugubha nokuqeda ukudideka ngaphansi okukhulu ushintsho amathangi.

izakhi impahla

Imisuka yedivayisi ezinemibala powder lokunameka umswakama nemithi, uyakwazi withstanding emfushane eside chemical kuhlasela nomaphi ukwehluleka nesenzakalo. Ngokuvamile, izingxenye zensimbi phezulu embozwe epulasitiki. Le isixazululo ikuvumela ukuba ungakhathazeki ngokuthola reagents ezingxenyeni ukuma.

Ingxenye engenhla we-tripod for amashubhu eyenziwe ngepulasitiki noma lensimbi elinezinhlangothi enamathela abicah yokungakhokhi esisheshayo ne reagents namakhemikhali. Lapho abaphuma ezimbili by metal rod, ezenziwe ngensimbi engagqwali asetshenziselwa eqinisa isakhiwo.

Ukudalulwa ingxenye metal izakhi yasibamba zakhiwe ngezinto okungezona ezonakalisayo wamandla yanda, ngaphezulu akhethiwe ukugqwala steel wezokwelapha.

iziqobosho

Ukubaluleka eyinhloko tripod laboratory ku yezinqubo zamakhemikhali ngokomzimba - it is ukulungisa zonke izinhlobo kwemishini yezokwelapha. Ngakho-ke, umgomo oyinhloko lapho ukhetha idivaysi efanelekayo iwukuhlale eguquguqukayo isicelo. Ngesikhathi yokubeka efanayo ngokuvamile ibekwe ngaphezu 3 izinhlobo iziqeshana ziyahlukahluka ngesipiliyoni ngamunye.

Ukukhweza Kit kungaba kuqukathe izinto ezilandelayo:

• Izikhundla ngaphansi kwetafula umoya isibani, isibani, kanye nezinye izingxenye isipiliyoni.
• Abanikazi couplings ogibele yokubeka zokuthola ezingeni ukuphakama ethile.
• izindandatho ezinkulu nezincane kanye neziqeshana esetshenziswa njengezinto zokuthutha for iziqukathi ahlukahlukene: flasks, ukuhlolwa amashubhu.
• Foot, clamping emphinjeni izitsha noma inkampani yenethiwekhi ingxenye elinye ithuluzi.
• Fixers ngoba burettes.

inhlangano ukulandelana

Ezikoleni kwamakhemikhali amakilasi sicala kwati lokuhle, ibaluleke ngani-Laboratory tripod. Ngezinhloso ukusebenzisa ukuqonda idivayisi wokuqala kwenziwe yokuhlangana yayo.

Kunconywa ukuba ulandele igxathu ukulandelana:

1. Uma uyikha phezulu le etafuleni setha isizinda esindayo.
2. Front kwakwakhe screwed ngokuphephile ukhiye isilungisiwe.
3. Okokuqala omncane bahlala endaweni yokubeka ahlukaniswe entabeni turntable.
4. Ukulandelana okwengeziwe ekhethwe njengedifolthi laboratory ukuze siqu ukusebenza yabo ethile.
5. Lapho kokuqina iziqobosho akunconywa ukusebenzisa eqile. Ukuthembeka kwakwakhe kwaphumela kumele ihlolwe ngaphambi kokufaka ingcindezi phezu kwalo amakhemikhali yokugeza izitsha. Sebenzisa izakhi ejwayelekile ngezinhloso akuhloselwe ngumkhiqizi akuhileli izingozi ezingase zibe khona ezibangelwa ukuhluleka tripod. Idlule umthwalo esungulwe futhi akudingekile, the yokubeka Ngeke kume, futhi wonke isakhiwo wawa ezinsikeni zawo.

Okumele kuqashelwe kobuso ukufakwa ukuma. Kufanele kube isihlobo uyisicaba kuya ovundlile. It kungavunyelwe for ucwaningo laboratory ngaphansi imilenze base buyela noma yiziphi izinto ngombono wokuba qondanisa isakhiwo. Ithebula ngaphansi ucwaningo kumele babe ukuqina ezinhle futhi ube phezulu flat.

Imodeli ukukhetha?

Nakuba yokubuka amamodeli ekhona zinqunywa ukubaluleka yini tripod kwamakhemikhali. Ukuze uthole umsebenzi othize liyadingeka ukuze ukhethe izici ezifanele: inani Ukukhweza, ukuphakama futhi uhlobo Racks, base isisindo, uhlobo izakhi enamathela. Uma ukuhlolwa eyengeziwe kayiyikumyekela munye, achithe kuzo imali eyengeziwe ku ukuthengwa isethi ezibizayo baba lutho.

Lapho inani elincane uketshezi ezonakalisayo abavunyelwe ukusebenzisa metal Racks ensimbi lashukumisa noma insimbi. Ukuze ukusebenza amashubhu emikhiqizweni funa polypropylene. Foot abanikazi zikhethwa kusukela abicah enamathela, ukuze bonakalise flasks ingilazi ebusweni nge ngocingo.

Izimfuneko imikhiqizo

Uma kubhekwa iyiphi tripod kufanele sinake izici ezilandelayo:

• Amandla yokubeka kanye izakhi ukukhiya kumele singeqi izikhathi eziningana isisindo ezisetshenziswa nsuku zonke kanye nezitsha.
• Ukuphakama yokubeka abakhethiwe efiselekayo kancane xaxa.
• Rubber lwezimpawu kudingeka silungise izitsha ngaphandle okunamathiselwe amaphuzu ezikhethekile.
• Engqamuzaneni ngalinye kumele kumakwe ne izinhlamvu nezinombolo uma usebenzisa tripod ukuze amashubhu. Inani le ngxenye kuhlolwa mkhuba, ikuvumela ukuba ngokushesha ukuthola umthamo oyifunayo hhayi ukudida nalawa amanye ama-reagents.
• Ukuba khona izindandatho ehlukahlukene, othayi, fixings ngoba uhlobo oluthize isipiliyoni.
• Qondisa lokushisa ukumelana tripod.
• Umgomo we disassembly neyokuqhuba imihlangano, kanye kalula isitoreji design izakhi.

onobuhle Universal tripods akukhetha kunoma iyiphi i-laboratory. Ezikoleni, kubalulekile ikakhulukazi ngenxa uhlu olukhulu nakho ezahlukene ekilasini Chemistry, Biology, Physics. Inani elikhulu abafundi akusho ukukhetha imodeli buthaka amandla tripods. Lokunye lokubaluleke kakhulu kalula inhlangano, ngaphandle kokusebenzisa okhiye ezengeziwe.

siphephe uma usebenza nge ukuma

It belulekwa ukuba ufunde imiyalelo enikezelwe operation kahle imishini kwezokwelapha. Zonke iziqobosho isakhiwo ovunyelwe uyasikrufulula kuphela ngemva reagents isuswa endaweni umsebenzi. Liquid kukhishelwa ngangokunokwenzeka. Uma kushisa, lapho uvumela isikhathi sokwehlisa.

I flasks yanconywa ukudubula nge imilenze ivaliwe. Lapho izakhi eziningana clamping, unyawo lokuqala engenhla unscrewed okwengeziwe ngokulandelana ukususa umthamo asele. Ungazami buthaka Ukugunda okunamathiselwe ngqo yokubeka. Okokuqala ukuyidlulisa unyawo, nje ubambe entanyeni umfuma uqobo.
