Nekuenderera mberi kwekuvandudza uye kukwana kweakasiyana maitiro ekugadzirisa, zvinhu zvepolymer zvinogadzirwa kuita zvigadzirwa zvakasiyana uye zvinoshandiswa muminda yakawanda.Serological pipetteszvinhu zvinoraswa murabhoritari zvinoshandiswa kuyera nemazvo kana kutamisa zvinwiwa.Iwo anowanzo gadzirwa ne polystyrene (PS).PS haina ruvara uye yakajeka thermoplastic ine anotevera maitiro:

1. Mechanical properties: PS chinhu chakaoma uye chine brittle ine ductility shoma uye hapana kubereka kana yakatambanudzwa.Iyo mechanic zvimiro zve polystyrene zvine hukama neiyo synthesis nzira, yakaenzana mamorekuru, tembiricha, kusachena kwemukati uye nzira dzekuyedza.

2. Thermal properties: PS ine hutsika husina kunaka hwekupisa, nekupisa kwekushisa kwe70 kusvika 95 ° C uye kushandiswa kwenguva refu kwekushisa kwe60 kusvika ku80 ° C.Naizvozvo,serological pipetteshaigone kucheneswa nekupisa kwakanyanya uye kudzvanywa kwepamusoro, uye radiation sterilization inowanzosarudzwa.Thermal conductivity ye polystyrene yakadzikira, ingangoita 0.10 ~ 0.13W/(m·K), uye haina kushanduka nekuchinja kwekushisa.Icho chinhu chakanaka chekupisa chinopisa.

3. Magetsi zvinhu: PS isiri-polar polymer, uye mashoma mafiritsi uye anowedzera anowedzerwa panguva yekushandiswa.Naizvozvo, ine yakanaka dielectric zvimiro uye insulation, uye ayo dielectric zvimiro hazvina chekuita nehuwandu.

4. Mishonga yemakemikari: PS ine kugadzikana kwakanaka kwemakemikari uye inogona kumira zvakasiyana-siyana alkali, general acids, munyu, mineral oil, doro shoma uye zvakasiyana-siyana organic acids.

Izvo zviri pamusoro ndezvimwe zvezvinhu zvezvinhu zveserological pipettes.Kugadzikana kwakanaka kwemakemikari kunovimbisa kuti mhinduro uye chubhu haizoiti, nokudaro kuve nechokwadi chekururama kwekuedza.
