Devices, systems, methods and kits are provided for use in determining the concentration of chemical and biochemical components in aqueous fluids. The subject devices include test strips which define a longitudinal axis and include a distal edge configured for insertion into a measurement instrument and having an alignment notch formed in the distal edge for engagement with an alignment member of the measurement instrument. The alignment notch has opposing edges wherein at least a portion of the opposing edges is in substantially parallel relation to the longitudinal axis. In using the subject devices, the devices are inserted into a measurement instrument having an alignment pin. When operatively engaged with the alignment pin, the notch serves to maintain the device in a substantially motionless position. The invention is useful in a variety of applications, particularly in the determination of blood glucose concentrations.

The invention discloses a grinding tool kit, equipment and method used for rolling surface finishing of tapered rollers. The equipment comprises a main machine, an outer circulation system, the grinding tool kit and a grinding tool kit clamp. The structure of the main machine comprises a grinding strip assembly rotary type and a grinding sleeve rotary type. The outer circulation system comprises a collecting unit, an arranging unit, a feeding unit and a conveying system. The grinding tool kit comprises a grinding sleeve and a grinding strip assembly, the grinding sleeve keeps coaxial during working, the grinding strip assembly penetrates through the grinding sleeve, a cylindrical spiral groove is formed in the inner surface of the grinding sleeve, and the grinding strip assembly comprises multiple grinding strips which are distributed in a circumferential columnar array manner, and linear grooves are formed in the front faces of the grinding strips. During grinding, under the action of friction and pushing of a spiral groove working face and linear groove working faces, tapered rollers move along the linear grooves and the spiral groove while rotating along the axes of the tapered rollers, and therefore grinding of the rolling surfaces of the tapered rollers is achieved. By means of the grinding tool kit, equipment and method, the size consistency of the rolling surfaces of the tapered rollers can be improved.

Methods and apparatus for preparing autologous blood serum eye drops within a potentially contaminating environment are disclosed. Key convenience kit apparatus providing novel methodology includes a plastic bag in which an innovative tray securely holds a plurality of empty eye drop bottles and associated caps disposed and sealed therein. Providing the only access pathway into the bag is a sterilizing filter appliance which filters all fluid entering the bag and provides a nozzle for dispensing into bottles disposed in the tray. The key convenience kit apparatus is sterilized prior to use, assuring all components disposed within the bag are within a desired sterility assurance level. The sterilized state of items associated with the key apparatus is maintained by the single pathway for fluid. Capping and sealing the bottles before opening the bag permits delivery of sterile product for use outside the bag.
