I-Serum sisondlo esibalulekileyo kwinkcubeko yeeseli kwaye idlala indima ebalulekileyo ekuphuculeni ukukhula kweeseli.Ukhetho lweibhotile serum igqiba ukuba i-serum ingagcinwa kakuhle kwaye igcinwe i-aseptic.

I-Serum ibhekisa kulwelo olukhanyayo olutyheli olucacileyo olwahlulwe kwi-plasma emva kokususwa kwe-fibrinogen kunye nezinto ezithile zokudityaniswa kwe-blood coagulation, okanye ibhekisa kwi-plasma esusiweyo kwi-fibrinogen.Ngokubanzi, ubushushu bokugcina ngu -5 ℃ ukuya -20 ℃.Okwangoku, i-PET yeyona nto iphambili yeebhotile zeserum kwimarike.

Nangona iglasi ingasetyenziswa ngokuphindaphindiweyo, inkqubo yokucoca kunye nokuvala inzala inzima kwaye kulula ukuyiqhawula.Ke ngoko, izixhobo zePET ezinezibonelelo zokusebenza ezicacileyo ngokuthe ngcembe zibe lukhetho lokuqala kwiibhotile zeserum.Imathiriyeli ekrwada ye-PET inezi mpawu zilandelayo:

1. ukungafihli: Izinto ze-PET zinokucaca okuphezulu, zinokuvala ukukhanya kwe-ultraviolet, i-gloss enhle, umzimba webhotile ocacileyo ulungele ukujonga umthamo webhotile ye-serum kwibhotile.

2. iimpawu zoomatshini: amandla empembelelo ye-PET ngama-3 ~ 5 amaxesha ezinye iifilimu, ukuchasana kakuhle kokugoqa.

3. ukuxhathisa i-corrosion: ukuxhathisa i-oyile, ukuxhathisa kwamafutha, ukuxhathisa kwe-asidi, ukuxhathisa kwe-alkali, ezininzi izinyibilikisi.

4. ukumelana nobushushu obuphantsi: Ubushushu be-PET embrittlement yi -70 ℃, kwi -30 ℃ isenobunzima obuthile.

5. umqobo: igesi kunye nomphunga wamanzi permeability iphantsi, zombini igesi egqwesileyo, amanzi, ioli kunye nevumba ukusebenza.

6. ukhuseleko: non-toxic, incasa, impilo entle kunye nokhuseleko, ingasetyenziselwa ngqo ukupakisha ukutya.

Ukumelana nobushushu obuphantsi, ukungafihli kunye nezithintelo zezinto zePET kuyenza ibe yimathiriyeli ekrwada elungileyo yokuveliswa kwebhotile yeserum.Phakathi kweglasi kunye ne-PET izinto ezimbini, amaziko ophando lwesayensi, iinkampani zamachiza nazo zityekele ngakumbi kwi-PET imathiriyeli ekrwada.
