Ndi Galasi Yanji Imapangidwa Ndi Magalasi Ambiri A Laboratory

Kuyamba:

Laborator glassware ndi gawo lofunikira pakukhazikitsa kulikonse kwasayansi, kuyambira ma laboratories akusekondale mpaka malo ofufuzira apamwamba kwambiri. Kaya mukugwira ntchito ndi ma beak, ma flasks, machubu oyesera, kapena mabatire, kumvetsetsa mtundu wa galasi logwiritsidwa ntchito pazida za labotale kumatha kukhudza kwambiri zoyeserera zanu.

Koma mtundu wanji wagalasi womwe umagwiritsidwa ntchito kwambiri magalasi a labotale? Mu bukhuli lathunthu, tifufuza za zinthu zomwe zimapanga magalasi ambiri a labotale, molunjika pa zomwe zili, ntchito, ndi chifukwa chake zili zofunika. Ngati mukufuna kukweza magwiridwe antchito a labu yanu, nkhaniyi ikupatsani zidziwitso zonse zofunika zomwe mukufuna.

1. Sayansi Kumbuyo kwa Laboratory Glassware Zida

Magalasi a labotale amapangidwa makamaka kuchokera ku mitundu ina yagalasi yomwe imapereka mphamvu yabwino, kukana mankhwala, komanso kumveka bwino. Kumvetsetsa kusiyana pakati pa zipangizozi kungapangitse kusiyana kwakukulu posankha zida zoyenera zoyesera zanu.

Galasi Wam Borosilicate ndiye mfumu yosatsutsika ikafika ku labotale glassware. Zimapanga zinthu zambiri zamagalasi asayansi chifukwa cha mawonekedwe ake apadera omwe amalola kuthana ndi kupsinjika kwamatenthedwe komanso kusintha kwamankhwala. Chizindikiro chodziwika bwino cha galasi la borosilicate ndi Pyrex, chomwe chimagwiritsidwa ntchito kwambiri m'ma laboratories a maphunziro ndi mafakitale.

Mbali inayi, Soda-mandimu galasi, ngakhale kuti ndizochepa kwambiri m'ma laboratories ogwira ntchito kwambiri, zimagwiritsidwanso ntchito kwambiri m'mapulogalamu ena. Simalimbana ndi kusinthasintha kwa kutentha ndi mankhwala poyerekeza ndi borosilicate koma ndi yotsika mtengo komanso yoyenera kugwiritsidwa ntchito mu labotale.

2. Chifukwa Chake Galasi ya Borosilicate Ndi Yosankha Yokondedwa

Galasi ya Borosilicate imapangidwa pophatikiza silika ndi boron trioxide, zomwe zimapangitsa kuti siginecha yake ikhale yolimba komanso yokana. Zinthu izi zimayamikiridwa kwambiri chifukwa cha:

Zofunika Kwambiri za Galasi la Borosilicate:

1. Thermal Shock Resistance: Galasi ya Borosilicate ili ndi coefficient yotsika yowonjezera kutentha, kutanthauza kuti imatha kuthana ndi kusinthasintha kwa kutentha popanda kusweka kapena kusweka. Izi zimapangitsa kuti ikhale yabwino kwa mapulogalamu monga ntchito ya mbale yotentha, autoclaving, ndi kutentha kwamoto mwachindunji.
2. Kukaniza Chemical: Kapangidwe ka magalasi a borosilicate kumapangitsa kukana kwabwino kwa ma acid, maziko, ndi zosungunulira zosiyanasiyana zomwe zimagwiritsidwa ntchito m'ma laboratories. Izi zimatsimikizira kukhulupirika kwa zoyeserera ndikuchepetsa chiopsezo cha kuipitsidwa.
3. kwake: Magalasi a Borosilicate ndi olimba modabwitsa komanso osagwirizana ndi kupsinjika kwamakina, amachepetsa mwayi wosweka mwangozi pakagwiridwe ndi kugwiritsidwa ntchito tsiku ndi tsiku.
4. Kuwonekera: Magalasi a Borosilicate amakhalabe omveka bwino, amalola kuwunika momveka bwino ndikuwunika kosavuta kwa zoyeserera ndi njira.

3. Soda-Lime Glass mu Lab Applications

Ngakhale galasi la borosilicate limayang'ana kwambiri pakuchita bwino, soda-laimu galasi ikugwiritsidwabe ntchito mofala popangira ma laboratory. Magalasi a soda amapangidwa posakaniza silika ndi sodium oxide ndi calcium oxide, ndipo ndi galasi lotsika mtengo kwambiri lomwe limapezeka tsiku ndi tsiku monga zotengera ndi magalasi ogwiritsidwa ntchito nthawi zonse.

Ngakhale galasi ya soda-laimu ilibe kutentha ndi kukana kwa mankhwala a galasi la borosilicate, mphamvu yake imapangitsa kukhala njira yabwino pazochitika zomwe sizifuna kulondola kwambiri. Ndiwosavuta kupanga ndikuwumba, zomwe zimapangitsa kuti ikhale chisankho chopangira ma labure opangidwa mochuluka, otsika mtengo.

4. Mitundu Yodziwika ya Glassware ya Laboratory ndi Zida Zawo

Tiyeni tiwone mitundu ya magalasi omwe amagwiritsidwa ntchito pazinthu za labotale:

• Beakers: Nthawi zambiri amapangidwa ndi galasi la borosilicate kuti apirire kutentha komanso kukhudzana ndi mankhwala.
• Flasks (Erlenmeyer, Yozungulira-pansi): Izi nthawi zambiri zimakhala borosilicate chifukwa chofuna kuthana ndi kusintha kwa kutentha panthawi yosakaniza kapena kutentha.
• Machubu Oyesera: Machubu ambiri oyesera amapangidwa kuchokera kugalasi la borosilicate, ngakhale kuti ena amapangidwa kuchokera ku galasi la soda-laimu kuti agwire ntchito zosafunika kwenikweni.
• Burettes ndi Pipettes: Zida zolondola izi zimapangidwa ndi galasi la borosilicate kuti limveke bwino komanso kukana kuyanjana kwamankhwala.
• Zakudya za Petri: Izi nthawi zambiri zimapangidwa ndi magalasi a soda-laimu popeza safuna kulekerera kutentha kwambiri komwe ma labware ena amachita.

5. Galasi yokhala ndi zokutira kapena zowonjezera

Magalasi ena a labotale amatha kukhala ndi zokutira zapadera kapena zowonjezera kuti ziwongolere katundu wawo. Mwachitsanzo, Magalasi a pyrex ikhoza kukutidwa ndi malo osakhala ndi ndodo kuti mupewe kuchulukana kwa zotsalira za mankhwala. Kuonjezera apo, silika wosakanikirana imagwiritsidwa ntchito m'mapulogalamu apamwamba asayansi pomwe chiyero chapamwamba chimafunikira.

Mafunso Omwe Amafunsidwa Kawirikawiri Okhudza Laboratory Glassware

Q: Kodi galasi la borosilicate lingagwiritsidwe ntchito mu microwave?

A: Inde, galasi la borosilicate ndi lotetezeka mu microwave chifukwa cha kutsika kwake kwa kutentha komanso kukana kugwedezeka kwa kutentha. Izi zimapangitsa kuti zikhale zoyenera kutentha ndi kutenthetsanso zitsanzo mu labu.

Q: Kodi galasi la borosilicate limafanana bwanji ndi galasi la quartz ponena za kukana kutentha?

A: Ngakhale magalasi onse a borosilicate ndi a quartz ndi osatentha kwambiri, magalasi a quartz amatha kupirira kutentha kwambiri, zomwe zimapangitsa kukhala chisankho chokondedwa cha ntchito zapadera monga ng'anjo zotentha kwambiri ndi uvuni.

Q: Kodi galasi la borosilicate likhoza kutsekedwa?

A: Ndithu! Galasi ya Borosilicate ndi chinthu chabwino chopangira autoclaving chifukwa cha kuthekera kwake kupirira kutentha kwambiri komanso kupsinjika komwe kumakhudzidwa ndi njira yolera yotseketsa.

Q: Kodi pali kusiyana kotani pakati pa galasi la borosilicate ndi pyrex?

A: Pyrex ndi mtundu wina wa galasi la borosilicate lomwe linapangidwa ndi Corning kumayambiriro kwa zaka za zana la 20. Ngakhale kuti Pyrex ndi mtundu wa galasi la borosilicate, si magalasi onse a borosilicate ndi Pyrex.

Q: Kodi ndingadziwe bwanji galasi borosilicate mu labu?

Yankho: Galasi ya Borosilicate imadziwika ndi utoto wake wowoneka bwino wabuluu kapena kupezeka kwa "boro" kapena "borosilicate" pamagalasi.
