Abstract

Die Erfindung betrifft eine Durchflusszentrifuge (1) mit einem Rotor (6). Die Durchflusszentrifuge (1) verfügt über einen Verbindungsstrang (12), der Anschlussleitungen (16, 17) aufweist, über welche ein Austausch von Medien in Behältnissen (8a, 8b), die in Zentrifugationskammern des Rotors (6) angeordnet sind, möglich ist. Erfindungsgemäß erstrecken sich durch den Verbindungsstrang (12) eine Temperier-Zuführleitung (14) und Temperier-Abführleitung (15) für ein Verbindungsstrang-Temperierfluid, um einer Erwärmung des Verbindungsstrangs (12) infolge der darin auftretenden Walkarbeit und Reibung entgegenzuwirken. Die Temperier-Zuführleitung (14) und die Temperier-Abführleitung (15) werden in entgegengesetzte Strömungsrichtungen von dem Verbindungsstrang-Temperierfluid durchströmt.

The invention relates to a flow centrifuge (1) with a rotor (6). The flow centrifuge (1) has a connecting strand (12) which has connection lines (16, 17) via which an exchange of media in containers (8a, 8b) which are arranged in centrifugation chambers of the rotor (6) is possible. According to the invention, a temperature control supply line (14) and a temperature control discharge line (15) for a connecting line temperature control fluid extend through the connecting line (12) in order to counteract heating of the connecting line (12) as a result of the flexing work and friction occurring therein. The connecting line temperature control fluid flows through the temperature control supply line (14) and the temperature control discharge line (15) in opposite flow directions.
