Theta profiles

Simple capillaries with septum

The main feature of our theta cross-section capillaries is their four completely separate chambers in a round cross-section. The individual inner chambers are separated from each other by the thinnest possible membrane, which remains fully intact even when drawing out to very thin tips.
They are ideally suited to liquid perfusion applications on cells, as the deformation of the cell wall or cell membrane can be reduced to a minimum.
In addition to the theta cross-section profiles, there are also capillaries with a septum creating two chambers. There is also the option of inserting filaments here.

Large-volume theta cross-section capillaries

We have further developed our small theta cross-section capillaries to now manufacture a larger version. The large-volume capillaries have a total diameter of max. 8 mm. The thin partitions separate the internal cross-section into four equally sized chambers, like a clover leaf. The tubes are used, for example, in reaction vessels in which several substances are encapsulated and can be released as necessary by breaking the tube.
