摘要： A capillary stabilizer for a liquid sample, consisting of a capillary and a supporting element (a holder) being characteristic in that the capillary (1) is made of borosilicate glass and has a length in the range from 35.0 to 60.0 mm, an outer diameter in the range from 6.5 to 10.0 mm, and an inner diameter in the range from 1.2 to 1.8 mm. In the upper portion of the capillary there is a widening (2), which in its inlet portion has a diameter in the range of from 4.0 to 8.0 mm, and a height in the range of from 5.0 to 10.0 mm. In the lower portion of the capillary there is a widening (3) with a diameter of its base in the range of from 3.0 to 3.5 mm and a height in the range of from 0.7 to 1.0 mm. On the outer perimeter of the upper outlet of the capillary a chamfer (4) is made having a depth in the range of from 0.3 to 0.5 mm, simultaneously the capillary is placed in a supporting element (a holder) (5). Preferably, the capillary (1) has a funnel-shaped widening (4) in its upper portion. Preferably, the capillary (1) has a conical widening (3) in its lower portion.
Preferably, the holder (5) that is designed for operation at a room temperature is made of plastic. Preferably, the plastic from which the holder (5) is made is organic glass. Preferably, the holder (5) in the high-temperature variant is made of metal. Preferably, the metal from which the holder (5) is made is aluminum. Preferably, the holder (5) has a cylindrical hollow recess (6) at the bottom. Preferably, the holder (5) has a conical hollow recess (7) on the bottom located around the opening through which the capillary (1) passes.
