Claims (8)

1. Separator för separation av vätska, säsom blod, i en lätt fas och en tung fas i ett provrör, innefattande en kolv (12) med radiellt utskjutande tungor, kännetecknad av att koiven (12) är skälformig och har sluten botten (13A), frän vilken en första runtom gdende tunga (13) utskjuter radiellt, att koiven har en vätskegenomtränglig sidovägg och en andra runtom gäende, radiellt utskjutande tunga (14) anordnad pä nägot axiellt avständ frän den förstnämnda tungan (13), att tungorna (13, 1*0 är anord-nade att tätande anligga mot provrörets (10) insida och den förstnämnda tungan (13) är flexibel för att tilläta att den lättare fa-sen (18) passerar förbi densamma vid den skälformiga kolvens (12) förskjutning nedät genom den lättare fasen, samtidigt som den förstnämnda tungan (13) väsentligt förhindrar den tyngre fasen att passera tungan (13).
2. Anordning enligt patentkravet 1, kännetecknad av att det i kolvens (12) sidovägg finns axiellt längsträckta, genomgäende smala spalter (16),
3. Anordning enligt patentkravet 2, kännet ecknad av att de smala spalterna (16) utvidgar sig radiellt inät.
4. Anordning enligt patentkravet 2, kännetecknad av att de smala spalterna (16) förenas av en ytterkant (25) som oavbrutet omger kolvens (12) sidovägg och löper väsentligen mittemellan de tätande tungorna (13, 1*0.
5. Anordning enligt patentkravet 1, kännetecknad av att en löstagbar skjutanordning (19) är anordnad att skjuta koiven (12) nedät i provröret.
6. Anordning enligt patentkravet 1,kännetecknad
