Patinenge tiri murabhoritari tinoshandisa zvimwe zviridzwa zvinotibatsira kuita zviyero uye bvunzo. Chimwe chezviridzwa zvinoshandiswa zvakanyanya zvinomiririra chiitiko chakakosha munyika yekemisitiri uye fizikisi ndiyo volumetric chinu. Icho chishandiso chakakosha kwazvo zvese zvemberi uye zvekutsvaga kwakawanda kwesainzi zvidzidzo. Nekubatsira kuverenga nemazvo huwandu hwezvinwiwa zvinogona kuyerwa, chave chimwe chezvishandiso zvinoshandiswa zvakanyanya.
Muchikamu chino isu tichaenda kukuudza zvese hunhu, kukosha uye maitiro ekushandisa iyo volumetric flask.
Chii chinonzi volumetric flask
Iyo inozivikanwa zvakare nezita rekuti Fiola uye hachisi chinhu chinopfuura girazi mudziyo unoshandiswa mumarabhoritari. Nekuda kweichi chishandiso, zviyero chaizvo zvemvura zvinoyerera zvinogona kuwanikwa uye zvinoshandiswa kusanganisa zvinhu zvinozoshandiswa kumberi. Chinhu chakasarudzika ndechekuti chakagadzirwa negirazi uye chine mutsipa wakareba uye wakamanikana. Pasi paro rakatsetseka. Pamutsipa pane mucherechedzo unonzi gauging, saka izita rayo. Iko kugona kuri mukutarisira kuratidza huwandu hwemvura iyo iyo volumetric flask inofanira kunge iine kuitira kuvimbisa uye kufambisa chaiyo kuyerwa. Nenzira iyi, zviyero zvakafanana zvinokwanisika nechepadiki pekukanganisa.
Mucherechedzo wemutsipa unotanga kubva pachigadziko chakaita peari uye unomhanya wakayambuka mutsipa wakamanikana. Nenzira iyi, zvinokwanisika kupa mhando dzakasiyana dzezviyero zvevhoriyamu.
Chii icho
Iyo vhoriyamu flask inoshandiswa kuyera nenzira kwayo zviyero zvakasiyana zvezvinwiwa zvinogona kuwanikwa murabhoritari. Dzinogona kushandiswa kugadzira mamwe musanganiswa wezvinhu zvakasiyana uye uwane kurongeka pasina kuwedzeredza basa rayo. Ramba uchifunga kuti Mabhokisi mazhinji akakodzera chete kushandiswa mumarabhoritari echikoro. Aya maflasks anowanzo kuve nezvimwe zvinonyanya kukosha uye akasimba. Nekudaro, mumarabhoritari epamutemo pane mamwe marudzi emamwe mabhodhoro akajeka ane nziyo dzakasiyana uye anotsigira hukuru hukuru.
Chinhu chakanyanya kukosha usati watenga volumetric flask kuziva kuti chii chicha shandiswa. Nenzira iyi, isu tinokwanisa kusarudza yakanyatsokodzera modhi zvichienderana nekushandisa kuri kuzopihwa kwairi. Kuvhiya kwacho kuri nyore. Izvo zvinongodiwa chete kuti uzive kuti ndeapi mabhureki anodikanwa kuti uwane chiyero chaicho. Ichi chiyero chinogona kuve chehuwandu hwemvura kana musanganiswa wadzo. Basa hombe rerudzi rwevholumu ndeyekuyera huwandu hwemvura inoshandiswa nechero rabhoritari. Inogona zvakare kushandiswa kune chero mhando bvunzo kana kuyedza.
Nhanho inonyanya kukosha yekuziva kana uchishandisa volumetric flask ndeyekuita kusvika kune mucherechedzo. Kugadzira iko kuzadza volumetric flask munzira kwayo. Kuti uite izvi, zvakanakisa kushandisa fanera nekuti ine yakanyanya kutumirwa nhongonya. Sezvo iri yakapfava uye yakareba urefu, zviri nyore kuisa iyo mvura mukati mevolumetric flask. Nekuda kweizvi, isu tinowana zvirinani kunyatso sezvo isu tichimhanya shoma njodzi yekurasa. Izvo zvichatibatsirawo isu kuve neyakanyatso kuyerwa uye kunyaradza kukuru mukuita.
Imwe pfungwa yekufunga nezvayo patinoshandisa volumetric flask inguva iyo yatinofanira kuita kuyerwa. Iwe unofanirwa kutarisa pane yepakati poindi yeiyo curve iyo inogadzirisa mhinduro. Isu tinofanirwa kufunga kuti akawanda marabhasketi ane akakwirira micheto uye mamwe ane akadzika mapendero. Chero zvazviri, chinhu chakakosha ndechekuti isu tinofanirwa kugara tichitarisa pasimba. Iyi ndiyo chete nzira yekugona kudzora mushe nzvimbo yepakati yemhinduro curve. Isu tinofanirwa kutarisa kugona seyakatsetseka mutsara kuti tipe chokwadi chekuverenga kwemvura. Izvo hazvigone kuonekwa seyakapembera kana isu hatizove nemhedzisiro yatinotarisira.
Zvishandiso zvevolumetric flask
Izvo hazvishandiswe chete kuyera vhoriyamu yemvura, asi zvakare kugadzira akasiyana musanganiswa. Tichaganhura mashandisiro akasiyana eiyo volumetric flask:
- Edza huwandu hwezvinwiwa. Cherekedza mamaki pamutsipa wefuti segwara. Kutenda kwavari, tinogona kuyera huwandu hwemvura nekutarisa rakakombama kumusoro kana pasi.
- Gadzirira mhinduro: Rudzi rwebhasikiti runoshandawo kugadzirira mhinduro. Kana isu tichiziva huwandu hwesolute uye solvent, tinogona kusanganisa iyo huwandu hwatinoda. Kurema kwesolute kunoonekwa kuburikidza nechiyero. Chokumisa chobva chaiswa pabholamu remagetsi ndokuzungunuswa kudzamara zvikamu zvese zvasanganiswa pasina njodzi yekuparadza mhinduro.
Volumetric flask mhando
Kune mhando dzakasiyana dzevolumetric flask zvinoenderana nehumwe hunhu. Ngationgororei zvavari:
- Zvinoenderana neicho chokwadi: Tine volumetric flasks erudzi A ayo anoshandiswa kuyera zvinwiwa uye kugadzirira akasiyana masanganiswa. Ivo anoshandiswa mune epamberi kemisitiri marabhoritari. Type B volumetric flasks ndeaya anowanikwa mumarabhoritari echikoro aine zvakaderera zvinodiwa.
- Zvinoenderana nehukuru hwevhoriyamu: Kana zvasvika kune huwandu hwevhoriyamu yevholumetric flask, isu hatinongedze kune 1 uye 2 ml marabhasiki, kunyangwe iwo ari kubvira 25 ml kusvika 500 ml anowanzo shandiswa.
- Zvinoenderana neruvara: zvinoenderana nezvakakonzera izvi iwe unogona kuwana akasiyana mavara. Vamwe vane ruvara runodikanwa kuti vakwanise kugadzirisa misanganiswa inoenderana nechiedza. Ramba uchifunga kuti ivo vanofanirwa kuve nehutsanana hwakanaka kune chero mhando yechiyero. Kana iwe usina hutano hwakanaka, zviyero zvinogona kukanganiswa nekuchinjwa.
Sezvauri kuona, volumetric flask ndechimwe chezvishandiso zvinoshandiswa zvakanyanya pasi rese chemistry uye fizikisi uye marabhoritari. Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezve volumetric flask uye ayo makuru maitiro.
