The true mechanism also performs removal of the sample holder after feeding. The mechanism for inserting and removing the sample holder must be reliable.
Sammanfattning av uppfinningen Problem Isotermisk kalorimetri pa mikrowattnivan fordrar en noggrant styrd ternperatur med minimala fluktuationer. Insattning och uttagning eller fOrflyttning av provhallaren for flera flaskor kraver traditionellt en mekanisk koppling mellan provhallaren och forflyttningsmekanismen. Summary of the Invention Problem Isothermal calorimetry at the micro-watt level requires a carefully controlled temperature with minimal fluctuations. Inserting and removing or moving the sample holder for several bottles traditionally requires a mechanical coupling between the sample holder and the transfer mechanism.
En mekanisk koppling mellan provhallaren och forflyttningsmekanismen innebar en risk for overforing av varme mellan forflyttningsmekanismen och provhallaren i endera riktningen och salunda en eventuell st6rning av matningsintegri30 teten.

It is proposed that the first part comprises at least one retractable rod and that said at least one magnet is attached to the spirit of the retractable rod. The retractable rod is adapted to: retract the magnet to a position of the first part exceeding the distance of the magnetic field, thus preventing magnetic coupling between the magnet and the magnetic surface and only allowing physical contact for indentation when inserting and restoring the magnet to a distance from the duct to allow magnetic coupling between the magnet and the magnetic surface for extraction when extraction is performed.
Atnninstone den sektionen av provhallaren som innefattar den andra delen är tillverkad av omagnetiskt material. Atnninstone the section of the sample holder that includes the second part is made of non-magnetic material.
Med andarnal att uppna en styrd och tillfOrlitlig rorelse foreslas att den forsta delen innefattar tva eller flera magneter, i vilket fall den magnetiska ytan är 20 tillrackligt bred fOr att mojliggora magnetisk koppling med alla magneterna eller sa kan den eventuellt vara uppdelad i flera magnetiska ytor, dar varje yta är positionerad for att mOjliggOra magnetisk koppling med en eller flera magneter. Olika material kan anvandas for att bilda kopplingsmedlen. Namnda atminstone ena magnet kan vara en hOgeffektsmagnet av miniatyrtyp baserad pa neodym och den magnetiska ytan kan vara en jarnbaserad platta. In order to achieve a controlled and reliable movement, it is proposed that the first part comprises two or more magnets, in which case the magnetic surface is sufficiently wide to enable magnetic coupling with all the magnets or it may optionally be divided into several magnetic surfaces. where each surface is positioned to allow magnetic coupling with one or more magnets. Different materials can be used to form the coupling means. The at least one magnet may be a miniature type high power magnet based on neodymium and the magnetic surface may be an iron based plate.

With the aim of preventing any kind of heat transfer between the movable element and the sample holder, but in the spirit of maintaining a stable construction of the sample holder, it is proposed that the at least one non-magnetic material in the sample holder be made of plastic or aluminum. Also of the shell to prevent any kind of heat transfer between the movable element and the sample holder, it is suggested that the spirit of the movable element is made of plastic or aluminum. Advantages The advantages of a stirring mechanism according to the present invention consist of the possibility of placing a sample holder in the different calibration and cooking layers of the calorimeter with a movable element, where it is easy to make a connection to the sample holder to push or pull the sample holder and to disconnect and remove the sample holder so as not to increase the feed integrity.
Bara en begransad fysisk kontakt fordras fOr att utfOra infOrande eller uttagande av provhallaren utan att flagon varmeoverforing sker mellan provhallaren och det rorliga elementet samt utan fysisk kontakt under matningen. Only a limited physical contact is required to perform insertion or removal of the sample holder without flake heat transfer between the sample holder and the movable element and without physical contact during feeding.
