Indlela yokukhetha ithiphu ye-pipette yomhlaba wonke?

Ama-Pipettes amathuluzi aselabhorethri asetshenziselwa ukuphatha amasampula oketshezi. Cishe wonke ama-pipettes adinga amathiphu e-pipette ukuze enze umsebenzi wawo ohlosiwe. Ngokwemvelo, ukukhetha uhlobo olulungile lwethiphu ye-pipette yomhlaba wonke kuyadingeka.

Ithiphu ye-Pipette eyenziwe nge-virgin polypropylene yilona elivame kakhulu futhi elivumelana nemvelo. Amathiphu we-pipette ahlukaniswe abe izinhlobo eziningana ngokusekelwe emisebenzini yabo kanye nezakhiwo.

1.Uhlobo lokukhetha ithiphu ye-pipette:
● Amathiphu Okuhlunga
Ukufaka amapayipi kwakha ama-aerosol athwala ingozi yokungcoliswa okuphambene. Amathiphu okuhlunga afakwe isihlungi ukugwema ukwakheka kwama-aerosol. Lolu hlobo lwe-pipette lube usizo ku-PCR (i-polymerase chain reaction), ukuphatha i-RNA/DNA, amasampula abhalwe umsakazo, athathelwanayo, namasampula aguquguqukayo.
●Amathiphu Okugcina Okuphansi
Lawa macebiso abamba uketshezi oluncane kunalolo oluvame ukusetshenziswa, olusiza ukulondoloza amasampula/ama-reagents. Lawa macebiso mahle kumasampula e-viscous futhi agxile kakhulu. Nokho, lezi zeluleko ze-pipette zibiza kakhulu. Lokhu kulungele i-electrophoresis, ukuhlaziya amaprotheni, ukulandelana, nanoma yikuphi ukuhlola okusebenzisa uketshezi olubonakalayo nolugxilile.
●Amathiphu Amade
Kwesinye isikhathi ama-reagents noma amasampula anevolumu encane futhi angaphansi kwesitsha. Kusho ukubeka hhayi kuphela ithiphu ye-pipette kodwa futhi i-shaft ye-pipette ngaphakathi kwesitsha. Lokhu kwandisa ingozi yokungcola, ngakho-ke ukusebenzisa ithiphu ye-pipette elide kunelijwayelekile yilona elithatha indawo engcono kakhulu.
●Amathiphu amafushane
Izeluleko ezinwetshiwe ziba nzima uma amasampula edonsa noma efakwa emithonjeni emincane. Ngakho-ke, ukusebenzisa amathiphu amafushane nge-pipette ye-multichannel kufanelekile. Ngokufanayo, ukufaka amapayipi ngamathiphu amade kungacindezela izandla futhi kudinga indawo ebanzi yebhentshi. Ngakho-ke, ukushintshela kumathiphu amafushane ukuze ugweme lezi zimo kuyinketho engcono kakhulu.
●Wide Bore Amathiphu
Kwesinye isikhathi amasampula aphathwa ilabhorethri angaba ntekenteke futhi wonane ngenkathi edluliswa esuka endaweni ewumngcingo yamathiphu ajwayelekile. Ngakho-ke, ukusebenzisa amathiphu ane-orifice ebanzi kuyindlela engcono kakhulu yokuphatha amasampula afaka amaseli noma aminyene kakhulu.

2.Imibandela Yokukhetha Ithiphu Le-Pipette Elilungile Le-Universal:
Inqubo eyinhloko yokukhetha ithiphu le-pipette elifanele ukuhlolwa okwenzayo elabhorethri yakho. Amathiphu okuhlunga amagciwane ayadingeka uma uzama ukuhlola amangqamuzana elabhorethri. Kanye nokuhlolwa, kunemibandela eminingi okufanele icatshangelwe ngaphambi kokuthenga amathiphu. Zimi kanje:
●Imiqulu Yoketshezi Olusingathiwe
Umthamo wamasampula oketshezi noma ama-reagents uyahlukahluka kakhulu kumalabhorethri. Elabhorethri, kungcono kakhulu ukuba namathiphu obukhulu obuhlukahlukene nezinjongo.
●I-Pipette esetshenzisiwe
Uma uphatha amasampula amaningi ngesikhathi esilinganiselwe, ungasebenzisa i-pipette yeziteshi eziningi. Noma kunjalo, amalabhorethri ajwayelekile asebenzisa ama-micropipettes, ngakho-ke ukuthenga amathiphu afaneleka zombili izinhlobo ngobuningi kukonga kakhulu.
●Inkampani Encanyelwayo
Uma ukhetha ithiphu langaphambi kokuzala, udinga ukubheka inkampani ehlinzeka ngesitifiketi sokuvala inzalo. Ngokufanayo, amathiphu angewona oyinyumba angasetshenziswa kabusha uma inkampani ithi angakwazi ukuzenzela.
●Isabelomali
Isabelomali sakho siwumgomo wesibili oyinhloko wokukhetha ipayipi elifanele elabhorethri yakho. Amathiphu okuhlunga ayabiza uma eqhathaniswa namathiphu enhloso evamile. Ngakho-ke, uma isabelomali siqinile futhi ungazimisele ukwenza noma yiziphi izivivinyo zamangqamuzana, khona-ke ukuthenga amathiphu enhloso evamile kuyisinqumo esingcono kakhulu.

I-Cotaus ingumkhiqizi wamathiphu we-pipette womhlaba wonke ochwepheshe kanye nomphakeli, ehlinzeka amakhasimende ngezicaciso ezihlukahlukene zamathiphu e-pipette. Umkhiqizo ngamunye uhlangabezana nezidingo zekhwalithi yekhasimende. Khetha i-Cotaus ukukhetha ukunemba nokusebenza kahle.
