A cuvette for liquid samples, particularly for absorption spectrum analysis. The curvette has a multi-part housing structure enclosing a thin sample chamber which is delimited by two radiation transmitting discs and is provided with two bores leading to the sample chamber. Stoppers of a plastic material are inserted into the respective bores, each stopper being provided with a thin longitudinal channel which can be sealed by means of a hollow needle whose tip is inserted into it or by means of a closing needle.
