Mitundu ya 5 yazinthu zomwe zimagwiritsidwa ntchito popanga ma labotale apulasitiki

Kodi mumadziwa bwanji za zinthu zomwe zimagwiritsidwa ntchito ndi pulasitiki mu labotale?

Laboratorzogwiritsidwa ntchito, zomwe zimagwiritsidwa ntchito kwambiri panthawi yoyesera, ndizosiyana ndipo zimagawidwa m'magulu atatu akuluakulu: magalasi, pulasitiki ndi zitsulo, malinga ndi zomwe mapulasitiki akhala akugwiritsidwa ntchito kwambiri chifukwa cha katundu wawo wabwino kwambiri komanso kuumba kosavuta.Zida zodziwika bwino zimaphatikizapo magulu awa:

1. PE (polyethylene)

Opaque, olimba, osamva kukalamba, kulemera kopepuka, kusatayikira, mawonekedwe ofewa, komanso osagwira ntchito monga acetone, acetic acid, ndi hydrochloric acid, ndizokhazikika komanso zofewa mosavuta pakatentha kwambiri.

ConsumablesZomwe zimagwiritsidwa ntchito kwambiri ndi PE ndi:Mabotolo a Reagent, Pasteur Pipettes, Chikwama choyesa mawaya, Blender bag, Chikwama cha zinyalala zachipatala chokhazikika ...

2. FEP (fluorinated ethylene propylene copolymer)

Kutentha kowonekera kumatsika pang'ono ndipo kumatha kugwira ntchito - 85℃~+ 205℃kwa nthawi yayitali komanso pa -200℃~+ 300℃kwa nthawi yayitali;Mphamvu yamphamvu ndi yayikulu, kukana kukwawa, crystallinity imasiyanasiyana ndi kutentha kwa kutentha kwa kutentha, ndi kuumba kwabwino;Non-poizoni, si viscous, electroly insulating, abrasion kugonjetsedwa, mankhwala khola;Zowoneka bwino, zinyalala zobwezerezedwanso.

Wambazogwiritsidwa ntchitoza FEP zakuthupi ndi: mafani olekanitsa, ma flasks a Erlenmeyer, machubu othamanga kwambiri a centrifuge.

3. PS (polystyrene)

Manla, olimba ndi galasi kutembenuka kutentha pamwamba 100 ° C, khola njira amadzimadzi ambiri, koma dzimbiri ndi osiyanasiyana organics.

Zinthu zambiri zomwe zimagwiritsidwa ntchito pazachikhalidwe zama cell zimagwiritsa ntchito PS ngati zinthu, monga: mbale zamtundu wa ma cell, mbale za Petri, Mabotolo amtundu wa ma cell, mbale zama cell, mbale za Elisa, malupu olowetsa, zofalitsa ma cell, mapaipi a Serological…

4.PC (polycarbonate)

Imakhala ndi mphamvu zambiri komanso kukhazikika kwamphamvu, kulimba kwamphamvu, kuwonekera bwino, kuuma kwakukulu ndipo imatha kupha tizilombo toyambitsa matenda pa kutentha kwakukulu, koma sikulekerera ma acid amphamvu komanso zosungunulira zina monga mowa.

Zogulitsa za PCzida:

Erlenmeyer Flasks, bokosi losungirako la Cryogenic

5.PP (polypropylene)

Translucency, bwino mankhwala ndi kutentha bata, ndi kuuma kwambiri m'manja kuposa Pe, amene angagwiritsidwe ntchito pafupifupi 100 madigiri, koma pa kutentha otsika amakhala Chimaona, wosavala, okalamba mosavuta, dzimbiri kugonjetsedwa, ndi asidi wamba ndi alkali organic zosungunulira alibe kwenikweni kwenikweni. pa izo.

Zogulitsa za PCzida:

Machubu a Centrifuge, machubu a Cryogenic, machubu ang'onoang'ono (chitsanzo chosonkhanitsira chubu), machubu a PCR, mbale za PCR, mbale zakuya, zisa, maupangiri a Pipette, mabotolo a Reagent, machubu ochotsa ...

Mzere wa PP wa Labio ndi mzere wa PS umapezeka pamalonda mumitundu yambiri, yokhazikika komanso yodalirika, zopangira zonse zimaperekedwa mokwanira ndi zipangizo zachipatala zomwe zimatumizidwa kunja, zomwe zimatsimikizira kuti katundu wabwino wa physicochemical wa mankhwalawo, ndipo, nthawi zonse, gwero lokhutiritsa. zogulitsa ndi ntchito za ogula ndi abwenzi apakati padziko lonse lapansi.

Pamwambapa pali zida za labotale zomwe zimagwiritsidwa ntchito, ndikuwonjezereka kwa chidziwitso cha anthu odziteteza, magalasi osasunthika amasinthidwa pang'onopang'ono ndi zida zapulasitiki, kukhala zinthu wamba zomwe zimagwiritsidwa ntchito pazakudya.
