Abstract: The present invention relates to an apparatus designed to perform chemical reaction kinetics studies and more particularly to an apparatus which is capable of conducting accelerated automated kinetics studies with user-defined temperature profiles and sampling periods. The apparatus includes at least one hot reaction block for heating one or more reaction vessels and at least one cold reaction block for cooling the one or more reaction vessels after heating thereof. The apparatus includes a robotic device for transferring one reaction vessel from one hot reaction block to one cold reaction block and a controller having a user interface for inputting a predetermined temperature profile and a predetermined sampling interval.

Abstract: A high throughput high performance chromatography system operating at a high mixing pressure including a plurality of pressurized solvent reservoirs, e.g. pumps, each maintaining an associated solvent at a substantially constant pressure. A plurality of flow control valves are connected downstream or upstream of the reservoirs for controlling the flow rate of the solvent into the respective columns. The number of reservoirs equals the number of solvents. Accordingly, the system reduces the number of pumps required thereby saving money and space. Furthermore, the system increases sample throughput, accelerates method development and minimizes organic waste.

Abstract: The present invention provides an apparatus for automatically transferring and weighing a powder material. The apparatus comprises a weigh station including a device for weighing the powder material in a container. A transfer device for collecting and dispensing the powder material is provided in which the device has a hollow body having a first end and a second end. The first end being operatively connected to a vacuum source so that a vacuum is selectively formed in the body. A collecting/dispensing tip is detachably coupled to the second end of the body. The tip is a hollow member with a tip orifice at one end so that a vacuum is formed in the tip upon actuation of the vacuum source. A controller for causing the selective actuation of the vacuum source and movement of at least one of the transfer device and the container is provided.

Abstract: The present invention features a method and apparatus with a rotatable central reservoir and radially extending support arms for packing chromatographic columns at a consistent gradient of particle impact by using centripetal forces to independently accelerate particles comprising a bed material through a filling opening at one end of the column and continuously as they move axially along the length of the column to their packed destination. The method and apparatus are particularly suitable for use in packing capillary columns having an interior diameter of about 500 microns or less.
