Ka ntlafatso e tsoelang pele le phetheho ea mekhoa e fapaneng ea ts'ebetso, lisebelisoa tsa polymer li etsoa lihlahisoa tse fapaneng 'me li sebelisoa masimong a mangata.Li-pipette tsa serologicalke lisebelisoa tsa laboratori tse lahloang tse sebelisetsoang ho metha kapa ho fetisa metsi ka nepo.Ka kakaretso li entsoe ka polystyrene (PS).PS ke thermoplastic e se nang mebala ebile e pepenene e nang le litšobotsi tse latelang:

1. Lisebelisoa tsa mechine: PS ke thepa e thata le e brittle e nang le ductility e nyenyane haholo 'me ha e fane ha e otlolohile.Thepa ea mochini oa polystyrene e amana le mokhoa oa ho kopanya, boima ba limolek'hule, mocheso, litšila le mekhoa ea tlhahlobo.

2. Thermal properties: PS e na le mocheso o fokolang oa mocheso, o nang le mocheso oa mocheso oa mocheso oa 70 ho ea ho 95 ° C le mocheso oa nako e telele oa ho sebelisa 60 ho 80 ° C.Ka hona,li-pipette tsa serologicale ke ke ea etsoa sterilized ka mocheso o phahameng le khatello e phahameng, 'me ho etsoa sterilization ea mahlaseli ka kakaretso.Thermal conductivity ea polystyrene e tlaase, e ka bang 0.10 ~ 0.13W / (m·K), 'me ha e le hantle ha e fetohe ka liphetoho tsa mocheso.Ke thepa e ntle ea ho koala mocheso.

3. Lintho tsa motlakase: PS ke polymer e seng polar, 'me li-fillers tse seng kae le li-additives li kenngoa nakong ea tšebeliso.Ka hona, e na le thepa e ntle ea dielectric le ho kenya letsoho, 'me thepa ea eona ea dielectric ha e amane le maqhubu.

4. Lintho tsa lik'hemik'hale: PS e na le botsitso ba lik'hemik'hale tse batlang li le ntle 'me e khona ho mamella mefuta e sa tšoaneng ea alkali, li-acids tse akaretsang, letsoai, oli ea diminerale, lino tse tahang tse tlaase le mefuta e sa tšoaneng ea organic acid.

Tse ka holimo ke tse ling tsa litšobotsi tsa thepa eali-pipette tsa serological.Botsitso bo botle ba lik'hemik'hale bo tiisa hore tharollo le tube li ke ke tsa itšoara, kahoo li tiisa ho nepahala ha teko.
