摘要： There are disclosed pipette tips having a wettable exterior surface shaped to force liquid that wets it to not fall under the influence of gravity to the terminal surface at which the dispensing aperture is located. For this, the radius R.sub.o of that wettable surface at the terminal surface satisfies the equation (I) R.sub.o

摘要： A method of use is disclosed of a device that causes phase separation of whole blood, using much lower centrifugal forces. As a result, leukocytes are separated from blood cells having specific gravities of 1.09 g/ml or higher. The method preferably uses a separation chamber arranged so that its long dimension or axis is parallel, not perpendicular, to the spin axis, and a valve that allows automatic removal of the ligher phase(s).In one aspect, the method separates a lighter phase from a heavier phase, for example, lymphocytes from whole blood, using a centrifugal force of reduced amount. In another aspect, DNA is extracted readily from the separated lighter phase since it is less likely that the lighter phase will be contaminated by erythrocytes as occurs in conventional separation techniques.

摘要： A needle device and method of use are disclosed, wherein the needle moves out of and into a protective housing, between two operative positions, one of which causes the housing to shield the needle. Each operative position includes releasable locking detents to temporarily hold the needle in one of those positions, the holding force of one being less than the other. A third position beyond the one that shields the needle in the housing is used to permanently lock the needle in the housing against accidental reuse. The needle device can be used with a blood collection container or a syringe drug delivery container, each one releasably mating with the device during use.

摘要： There are disclosed coaters that repeatedly and intermittently apply a uniform, thin coating of liquid onto a support at a rate that does not exceed the maximum swell rate of the support. Thus, developer liquid can be applied to photographic paper supports without leaving behind liquid effluent.The coater features a delivery channel leading from a manifold chamber to a slit orifice, the channel being improved in that it contains a plurality of spaced-apart wall portions connecting the opposed flow surfaces of the delivery channel, that extend in a direction towards the slit orifice, and structure inside the orifice for coalescing the individual streams fed by these wall portions, into a continuous strip of liquid to be dispensed by the slit orifice.

摘要： A device is disclosed that causes phase separation of whole blood, using much lower centrifugal forces. As a result, lymphocytes are separated from blood cells having specific gravities of 1.08 g/ml or higher. The device features a separation chamber arranged so that its long dimension or axis is parallel, not perpendicular, to the spin axis, and a valve that allows automatic removal of the lighter phase(s). The valve is constructed to respond only to the head of liquid pressure generated by an increased centrifugal force, and not to that increased force alone.
