Abstract: An adjustable support apparatus including a base with horizontal support members is provided. The adjustable support apparatus includes a first upright support member of a first predetermined height that is supported at one end thereof on one of the horizontal support members, and an other end of the first upright support member has a first support that is generally parallel to the one of the horizontal support members. A second upright support member is supported at one end thereof on a second one of the horizontal support members, and an other end of the second upright support member has a second support that is generally parallel to the second one of the horizontal support members.

Abstract: The present invention pertains to a hemolysis sensor, a hemolysis sensor system and methods of utilizing the hemolysis sensor or hemolysis sensor system to monitor or detect hemolysis in a sample, such as a whole blood sample, a plasma sample, a serum sample or hemolyzed blood. The hemolysis sensor responds to extracellular hemoglobin levels, for example, extracellular hemoglobin in a whole blood sample as a method for detecting hemolysis in whole blood.

Abstract: A system for electrochemical measurement of glucose concentration in an undiluted test sample, e.g. blood is provided containing a sensor including a three-layered contiguous membrane. The membrane has a thickness of 50 to 130 microns, and is composed of a 1 to 10 micron thick first layer, a 10 to 30 micron thick second layer having an average pore diameter of 15 nanometers and a 40 to 80 micron thick third layer containing glucose oxidase. The third layer is less dense than the first and second layers and the first layer is more dense than the second layer. The layers of the membrane are fused together such that no clear distinction can be made between the layers at the boundary. The sensor is calibrated in a standard glucose solution which includes catalase as a hydrogen peroxide scavenger, and the sensor has a response that is linear throughout the concentration range of glucose in an undiluted sample.

Abstract: It has been found that imidazole and related buffers enhance the activity of certain preservatives, for example either (1) a mixture of 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one or (2) 5-bromo-5-nitro-1,3-dioxane, that are used in clinical diagnostic reagents. It has also been found that these buffers and certain surfactants, such as BRIJ 700 and related hydrophilic surfactants, enhance the precision and accuracy of enzyme biosensors.
