Ithiphu ye-pipette ihlinzekwa yinkampani yebhayoloji: i-elisa i-serum yezilwane, izinto ezisetshenziswayo ze-PCR ezine-fluorescent, umlomo wombhobho, ishubhu le-microcentrifuge, i-cryotube engenisiwe, isitsha seseli yesiko, ipuleti lesiko, ibhodlela lesiko, ithiphu elingenisiwe, insimbi namagilavu, okusebenzisekayo kwe-chromatography, izihlungi zesirinji. , njll.

I-pipette iyithuluzi lokuhlola le-du* ocwaningweni lwebhayoloji, futhi inombolo yamakhanda ayo okumunca insiza ekuhlolweni nayo inkulu kakhulu. Amathiphu okumunca emakethe ngokuyisisekelo enziwe ngepulasitiki ye-polypropylene (ipulasitiki engenambala futhi esobala enokungena kwamakhemikhali aphezulu kanye nebanga lokushisa elibanzi). Kodwa-ke, ikhwalithi ye-polypropylene efanayo izohluka kakhulu: amathiphu aphezulu ngokuvamile enziwe nge-polypropylene yemvelo, kuyilapho amathiphu ashibhile angase asebenzise ipulasitiki ye-polypropylene egaywe kabusha (kulokhu, singasho ingxenye yayo eyinhloko i-polypropylene).

Ngaphezu kwalokho, amathiphu amaningi azokwengeza inani elincane lezithasiselo phakathi nenqubo yokukhiqiza, ezivamile yilezi:

1. Impahla ye-Chromogenic.

Okuvame ukwaziwa emakethe ngokuthi ithiphu eliluhlaza okwesibhakabhaka (1000ul) kanye nethiphu eliphuzi (200ul), impahla ehambisanayo ethuthukisa umbala yengezwa ku-polypropylene (sithemba ukuthi iyi-masterbatch yekhwalithi ephezulu, hhayi izingulube zezimboni ezishibhile)

2. I-ejenti yokukhulula.

Siza ithiphu ukuba ihlukaniswe nesikhunta ngokushesha ngemva kokubunjwa. Yiqiniso, izithasiselo ezengeziwe, ayanda amathuba okusabela kwamakhemikhali okungathandeki ngesikhathi se-pipetting. Ngakho-ke ngenhlanhla, azikho izithasiselo ezingeziwe! Kodwa-ke, ngenxa yezidingo eziphakeme kakhulu zenqubo yokukhiqiza, imibhobho engazingezi nhlobo izithasiselo ayivamile emakethe.

Indima yesihlungi samathiphu:

Ngenxa yokuthi isihlungi sethiphu iyithiphu yesihlungi sesibili, umsebenzi waso omkhulu ngesikhathi sokusetshenziswa ukuvimbela ukungcoliswa okuphambene: ngokungafani nezinye izinhlobo zokuhlunga eziqukethe izithasiselo ezingavimbela ukusabela kwe-enzymatic, amathiphu ahlungiwe we-pipette ahlinzekwa ngu-Bunsen enziwe nge-Made of virgin pure. i-polyethylene ehlanganisiwe. Izinhlayiya ze-Hydrophobic polyethylene zivimbela ama-aerosols noketshezi ekumunceni emzimbeni we-pipette.

Isihlungi se-cartridge ye-shampoo silayishwa umshini ukuqinisekisa ukuthi asithinteki ngokuphelele ngesikhathi sokukhiqiza nokupakisha. Ziqinisekisiwe ukuthi azinayo i-RNase, i-DNase, i-DNA nokungcoliswa kwe-pyrogen. Ngaphezu kwalokho, zonke izihlungi zikhishwa inzalo ngaphambili ngemisebe ngemva kokupakishwa ukuze kuthuthukiswe ukuvikeleka kwamasampula ezinto eziphilayo.

Ukusetshenziswa kwamathiphu okuhlunga kungasetshenziswa ukuvimbela i-pipette ukuba ingalinyazwa isampula futhi ikhulise kakhulu impilo yesevisi ye-pipette.

Sisetshenziswa nini isihlungi sethiphu:

Isetshenziswa nini ithiphu lesihlungi sethiphu? Amathiphu ahlungiwe we-pipette kufanele asetshenziswe kuzo zonke izinhlelo zebhayoloji yamangqamuzana azwela ukungcola. Ithiphu yokuhlunga isiza ukunciphisa amathuba okwakheka kwentuthu, ivimbele ukungcoliswa kwe-aerosol, futhi ngaleyo ndlela ivikele i-pipette shaft ekungcolisweni. Ukwengeza, umgoqo wokuhlunga uvimbela isampula ekuthathweni kwe-pipette, ngaleyo ndlela ivimbele ukungcoliswa kwe-PCR.

Ithiphu yokuhlunga iphinde ivimbele isampula ekungeneni kwe-pipette futhi ibangele umonakalo ku-pipette ngesikhathi sokubhoboza.

Kungani kufanele usebenzise isihlungi sethiphu ukuze uthole igciwane?

Igciwane liyathelelana. Uma ithiphu lokuhlunga lingasetshenziselwa ukuhlukanisa igciwane kusampula ngesikhathi senqubo yokuthola igciwane, lizokwenza ukuthi igciwane lisakazwe nge-pipette;

Amasampula okuhlola ahlukile, futhi ithiphu lesihlungi lingahlela ukungcoliswa okuphambanayo kwesampula ngesikhathi senqubo yokufaka amapayipi.
