Centrifugerør som en skræddersyet løsning
For at imødekomme de mange forskellige krav tilbyder vi centrifuger i en bred vifte af formater, størrelser og materialer.
Anvendelse og kvalitet
Centrifugerør bruges overalt, hvor komponenterne skal opdeles - for eksempel til blodprøver for at adskille plasmaet, for at isolere proteiner eller DNA, for at indsamle cellekulturer eller mikroorganismer fra kulturer, for at koncentrere partikler fra miljøprøver... Anvendelsesmulighederne er mangfoldige.
De høje krav, der stilles til disse analyser, betyder også, at der ikke kan gås på kompromis med valget af de anvendte centrifugerør. Hos Th. Geyer satser vi derfor på højeste kvalitet og maksimal sikkerhed - selv ved maksimale hastigheder og højt centrifugaltryk.
Materialet
Du kan vælge mellem plast, glas og rustfrit stål til de anvendte råmaterialer. Mens rustfrit stål normalt spiller en underordnet rolle, er plast som polypropylen (PP), polyamid (PA), polyethylen (PE) eller polykarbonat (PC) standard i laboratorier og forskningsmiljøer. Afhængigt af plasttypen kan centrifugerørene modstå meget lave til meget høje temperaturer. De er stabile over for kemikalier og kan være gennemsigtige eller uigennemsigtige, alt efter behov.
Centrifugerør af glas imponerer med deres grundlæggende modstandsdygtighed over for kemikalier, syrer, baser og organiske opløsningsmidler. Glasvarianterne scorer point med deres genanvendelighed og holdbarhed over gennemsnittet. Hvis det er nødvendigt, giver glas mulighed for en høj grad af gennemsigtighed og er relativt let at håndtere. Hvis materialet udsættes for høje hastigheder under centrifugering, er plast normalt det bedste valg. Th. Geyer tilbyder centrifugerør i begge varianter.
Størrelserne
Th. Geyer opfylder de specifikke krav til centrifugerørenes dimensioner og kapacitet med et stort udvalg af forskellige størrelser. Disse kan være op til 500 mL, mens størrelser som 50 mL og 15 mL er tilgængelige for mindre påfyldningsvolumener. I mikroområdet er centrifugerørene mellem 1,5 mL og 0,2 mL, som hovedsageligt bruges i laboratorier. Vi tilbyder naturligvis et bredt udvalg af alle gængse formater.
Låget
Under centrifugering forhindrer låget på centrifugerøret væske i at lække ud. Traditionelt bruges skrue-, plug-in- eller push-in-låg til dette formål, som er nemme at lukke. Mikrocentrifugerør er normalt udstyret med et snap-on-låg. Til meget store varianter sikrer låg med gevind beskyttelse mod lækage. Du finder både modeller med og uden låg i vores sortiment. Afhængigt af dit valg kan du altid bestille propper og lignende separat.
Bunden
De forskellige bundvarianter opfylder også de respektive krav. Den koniske bund med sin let tilspidsede form giver mulighed for selektiv materialeopsamling, hvilket gør adskillelse og fjernelse meget lettere Prøveudbyttet er særligt højt. Alternativt kan du også vælge mellem selvstående centrifugerør med flad eller afrundet bund.
