ABSTRACT:
A test apparatus for measuring blood characteristics comprises a measuring head having a measuring electrode and a reference electrode arranged in spaced relationship and a closure membrane covering a portion of said head, and an attachment connectable to said head having a wall defining a support membrane which is engageable on the closure membrane. The attachment defines a chamber for the blood sample in which the support membrane forms a bottom wall thereof so that the membrane supporting the blood is in contact with the closure member and thus is capable of being heated by a heater contained in the head without coming into contact with or contaminating the blood sample. The attachment while permitting the measurement to be made does not allow the blood being tested to come into contact with the measuring head. The attachment may be either disposed of or cleaned for re-use.
