Blood Pipette Shaking Machine Mark II.
BLOOD PIPETTE SHAKING MACHINE MARK II BY K. C. PARRY Fromn the Medical Division, Atomic Energy Research Establishment, Harwell (RECEIVED FOR PUBLICATION JUNE 22, 1950) The blood pipette shaking machine previously reported (Parry and Simmonds, 1950) has been modified to incorporate various improvements. In the new machine (1) the pipettes lie in the same plane and there is greater ease of insert...

Thermoviridin appeared to be an organic acid which was dialyzable. The antibiotic showed maximum absorption in the range of 268 to 272 m,u. Thermoviridin was primarily active against the gram positive bacteria tested. A preliminary toxicity test in mice, consisting of a single intraperitoneal injection of 32 mg of material which had 25 thermoviridin units per mg, did not cause death in any case.

Curved quantum waveguides are known to bind particles. We show that a number of charged fermions in such a trap can be tuned by an external electrostatic eld; if the latter is slowly increased, the bent duct can serve as a single particle ejector.

An automatic pipette is a very useful equipment for any laboratory carrying out Kahn tests on a large number of sera. A number of devices were tried in a field laboratory which was functioning as a serological laboratory for the CeylonArmy Command during the years 1945 and 1946. A mechanical pipette which can easily be prepared with materials salvaged from a small workshop is described below. T...

Microfluidics has emerged as a powerful laboratory toolbox for biologists, allowing manipulation and analysis of processes at a cellular and sub-cellular level, through utilization of microfabricated features at size-scales relevant to that of a single cell. In the majority of microfluidic devices, sample processing and analysis occur within closed microchannels, imposing restrictions on sample...
