Kugawana Zambiri Zothandiza_▏Zinthu zogwiritsidwa ntchito ndi pulasitiki wamba m'ma laboratories

Wamba pulasitiki consumable zipangizo m'ma laboratories

Pali zosiyanasiyana zoyesera.Kuphatikiza pa magalasi ogwiritsira ntchito, omwe amagwiritsidwa ntchito kwambiri ndi pulasitiki.Ndiye kodi mukudziwa zomwe pulasitiki zogwiritsidwa ntchito pa moyo watsiku ndi tsiku zimapangidwa?Ndi makhalidwe otani?Kodi kusankha?Tiyeni tiyankhe mmodzimmodzi monga pansipa.

Zinthu zapulasitiki zomwe zimagwiritsidwa ntchito mu labotale ndizo makamakamalangizo a pipettemachubu a centrifuge,Zithunzi za PCR, mbale za chikhalidwe cha ma cell / mbale / mabotolo, cryovials, etc. Zambiri za nsonga za pipette, mbale za PCR, cryovials ndi zina zomwe zimagwiritsidwa ntchito ndi PP.zinthu (polypropylene),cell chikhalidwe consumablesnthawi zambiri amapangidwa ndi PS (polystyrene), ma flasks amtundu wama cell amapangidwa ndi PC (polycarbonate) kapena PETG (polyethylene terephthalate copolymer).

1. Polystyrene (PS)

Ili ndi njira yabwino yotumizira kuwala ndipo ilibe poizoni, imatumiza kuwala kwa 90%.Iwo ali wabwino kukana mankhwala kwa amadzimadzi zothetsera, koma osauka kukana zosungunulira.Zili ndi ubwino wina wamtengo wapatali poyerekeza ndi mapulasitiki ena.Kuwonekera kwakukulu ndi kuuma kwakukulu.

Zogulitsa za PS zimakhala zofooka pang'onopang'ono kutentha ndipo zimakhala zosavuta kusweka kapena kusweka zikagwetsedwa.Kutentha kosalekeza kogwiritsa ntchito kumakhala pafupifupi 60 ° C, ndipo kutentha kwapamwamba sikuyenera kupitirira 80 ° C.Sizingatsekedwe ndi kutentha kwambiri komanso kuthamanga kwambiri pa 121 ° C.Mutha kusankha kutsekereza mtengo wa ma elekitironi kapena kutsekereza mankhwala.

Mabotolo amtundu wa ma cell a Shandong Labio, mbale za chikhalidwe cha ma cell, mbale zama cell, ndi mapaipi a serological onse amapangidwa ndi polystyrene (PS).

2. Polypropylene (PP)

Mapangidwe a polypropylene (PP) ndi ofanana ndi polyethylene (PE).Ndi utomoni wa thermoplastic wopangidwa kuchokera ku polymerization ya propylene.Nthawi zambiri imakhala yolimba yopanda mtundu, yopanda fungo komanso yopanda poizoni.Ubwino wake waukulu ndikuti utha kugwiritsidwa ntchito pakutentha kwambiri komanso kupsinjika kwa 121 ° C.Samalirani.

Polypropylene (PP) ili ndi zida zabwino zamakina komanso kukana mankhwala.Ikhoza kupirira dzimbiri za zidulo, alkalis, mchere zamadzimadzi ndi zosiyanasiyana zosungunulira organic pansi pa 80°C.Ili ndi kukhazikika bwino, mphamvu komanso kukana kutentha kuposa polyethylene (PE).;Pankhani ya kukana kutentha, PP imakhalanso yapamwamba kuposa PE.Chifukwa chake, mukafuna kufalitsa kuwala kapena kuyang'ana kosavuta, kapena kukana kupanikizika kwambiri kapena kutentha, mutha kusankha zogwiritsira ntchito PP.

3. Polycarbonate (PC)

Ili ndi kulimba kwabwino komanso kusasunthika, sikusweka mosavuta, ndipo imakhala ndi kukana kutentha komanso kukana ma radiation.Imakwaniritsa zofunikira za kutentha kwambiri komanso kupanikizika kwambiri komanso kuwongolera mphamvu zamagetsi m'munda wa biomedical.Polycarbonate (PC) nthawi zambiri imatha kuwoneka muzinthu zina, mongakuzizira mabokosindierlenmeyer botolo.

4. Polyethylene (PE)

Mtundu wa utomoni wa thermoplastic, wosanunkhiza, wopanda poizoni, umamveka ngati sera, umakhala ndi kukana kutentha kwambiri (kutentha kotsika kwambiri kumatha kufika -100~-70°C), ndipo kumafewa mosavuta pakatentha kwambiri.Ili ndi kukhazikika kwamankhwala abwino chifukwa mamolekyu a polima amalumikizidwa kudzera m'mabondi a carbon-carbon single ndipo amatha kukana kukokoloka kwa ma acid ambiri ndi ma alkali (osagonjetsedwa ndi ma acid okhala ndi oxidizing).

Mwachidule, polypropylene (PP) ndi polyethylene (PE) ndi mitundu yodziwika bwino ya mapulasitiki m'ma laboratories.Posankha zogwiritsira ntchito, nthawi zambiri mumatha kusankha ziwirizi ngati palibe zofunikira zapadera.Ngati pali zofunikira za kukana kutentha kwakukulu ndi kutentha kwakukulu ndi kutseketsa kwapamwamba, mukhoza kusankha zogwiritsira ntchito zopangidwa ndi polypropylene (PP);ngati muli ndi zofunika pa ntchito otsika kutentha, mukhoza kusankha polyethylene (PE);ndi zogulira zama cell ambiri amapangidwa ndi polystyrene (PS).
