    Abstract: The apparatus includes a sampling head adapted to be mounted at a sample pickup station. The head includes a hollow sample pickup probe adapted to be inserted into a sample container at the sample pickup station for extracting a given amount of fluid sample from the container. The pickup probe is movable between a first or sampling position and a second or retracted position by means of an air cylinder. A valve mechanism connected to the probe is operable on movement of the probe to the sampling position for connecting the probe to a device for withdrawing fluid from the sample container through the probe. The air cylinder not only moves the probe but also, and at the same time, operates the valve mechanism, between first and second valve positions. In the second position the valve mechanism effects fluid connections for mixing a given amount of the fluid sample with another fluid, for simultaneously transferring the mixture to a receptacle and for drawing de-ionized water through the probe for cleaning same. The apparatus also includes a water delivery trough and a mechanism for moving same into position under the raised probe. The air cylinder is operable to lower the probe into the trough with a lost motion mechanism of the sampling head permitting the valve mechanism to remain in the second valve position while the probe is so lowered.

    Abstract: A cuvette having a tubular body, an upper head portion and a lower substantially conically shaped portion having a central port defining an entrance. An examining chamber is defined within said cuvette body. The interior walls of said body are characterized by the absence of sharp angular junctions so that there are smooth transitions between adjacent planes within the chamber. A ball preferably of glass is seated at the entrance upon at least a pair of inwardly directed upset portions so that the ball is prevented from tightly seating in the cuvette entrance. The combination of the ball and upset portions provides an impedance to outflowing liquids from the chamber through the lower port. The head portion of the cuvette comprises an end cap or plug sealedly engaged removably within the upper end of the body and having a through passage terminating in a port directed to the body interior radially of the axis of said body. A probe secured to the lower end of the cuvette body at the entrance completes the cuvette assembly.

    Abstract: 1376684 Photo-electric testing COULTER ELECTRONICS Inc 10 Oct 1972 [14 Oct 1971] 46659/72 Heading G1A [Also in Division F1] A cuvette for photometric analysis of a sample comprises a transparent cylinder 28 Fig.3 having upper and lower cylinder heads 76, 64 with central ports 94, 74, a hollow probe 68 depending from the lower port and a free piston-like cylindrical member 84, disposed within the cylinder and having an outer diameter less than the inner diameter of the cylinder 28 by a capillary degree, the member 84 being shaped sealingly to engage O ring 82 which forms an upper valve seat, but to engage the lower cylinder head in a manner permitting the flow of gaseous and liquid fluids through the port when so engaged. The housing around the cuvette includes a lamp source 50 for directing light of a wavelength determined by filter 18 through the cuvette to a photo-cell 26. The cuvette operation is controlled by the programmed application of a vacuum or pressure to the top port, an initial application of gas under pressure serving to mix the sample before it is drawn into the cuvette by a succeeding vacuum, and a final application of pressure serving for scavenging. The member 84 and the cylinder heads may be of carbon.

    Abstract: Lipaemic blood serum is clarified by forming an interface between a body of lipaemic serum and a lipid-specific solvent having a specific gravity less than the serium, and subjecting the interfaced liqs. to a centrifugal field having a min. field strength of 1000 RCF for a predetermined duration while maintaining the integrity of the interface so that the solvent rides centripetally relative to teh lipaemic serum body, then removing the interfaced liqs. and withdrawing one of the resultant solvent and serum layers without disturbing the other. The method is useful for clarifying the lipaemic blood serum samples having turbidity due to chylomicrons without subjecting the serum samples to the disadvantages encountered using either centrifugation alone or extn. with specific solvents. Suitable solvents which can be used incl. opt. halogenated aliphatic or aromatic which are lipid solvents, immiscible with water and sp. gravity less than 1.030, e.G. ether, pet. ether, CHCl3 etc.
