  • Reaction vessel for receiving minimal quantities of fluid samples
    Patent number: 5167929
    Abstract: In accordance with the invention, a method for executing reactions at temperatures exceeding 50.degree. C. is disclosed using minimal quantities of fluid samples. The method uses a reaction vessel which minimizes the containment space for the fluid sample. The reaction vessel includes a sample-receiving tube and an insert. The insert engages the sample-receiving tube, forming a seal and prevents evaporation of the fluid sample during heating. The sample-receiving tube of the method is tapered to be narrow towards the bottom so that the insert can be easily inserted into the sample-receiving tube from the top and provide a tight seal in the lower extremity without increasing pressure in the reaction chamber. Equalization between the two sides of the sealing insert can occur as the insert is being introduced. Minimal displacement of the insert in the axial direction of the sample-receiving tube produces a sealing connection minimizing undesirable pressure build up.

  • Blood storage device
    Patent number: 4769025
    Abstract: A blood storage device consists of a blood extraction tubule (20) and a removable cover (12) which closes its upper opening. The cover (12) consists of a closure member (21) with a small opening (14) and a slider (13) arranged in the closure member (21) by means of which the passage of air from the inner space (17) of the blood extraction tubule (20) through the opening (14) can be interrupted.
