Abstract: This invention relates to a disposable pipette tip or tube designed to perform biological or chemical sample preparation, purification or separation where the samples are in a closed bottle with a lid with septum or membrane. In an automatic sampler for HPLC or Gas chromatography, septum closed vials are used to prevent samples from drying out or evaporating during the analytical process. The auto sampler needles are used to prick the septum at the vial to get the sample out for injecting in injector for the analysis. The same needle takes the samples from each vial, and therefore a contamination of the samples is possible.

Abstract: A spherical dialysis chamber with a heavier cap (the density of cap material is higher than that of the dialyzer) or the distribution of weight is such that it is higher weight distribution is towards the cap, so that it tilts always towards the bottom of the container containing the dialysis buffer.

Abstract: In the present invention, dialysis tubing is placed in a chamber, where an ultrasonic or a other mist producer is present. The ultrasonic mist producer will produce mist and small water droplets will be attached to the surface of dialysis membrane (sheet or tubing) and will condense and the water drops will fall back in the solution tank, where the ultrasonic probe produces the mist. When the droplet is attached to the membrane surface, the dialysis will take place.

Abstract: In this invention we describe a shaking device that is used to shake, stir, mix, rotate or agitate samples in containers attached to the shaking device. The shaking device, herein referred to as the shaker, is used to mix the solid, liquid or gaseous components of the sample in the container. The shaker described in this invention has a flexible arm to which the containers containing samples are attached. Due to the flexibility of the arm, its shape can be changed such that the speed and type of sample shaking can be varied based on the shape of the arm and based on where on the arm a sample container is attached. In this manner, orbital, linear, circular and other two or three-dimensional shaking, mixing, agitation and stirring of the sample can be achieved. The present invention provides an easy new method for shaking samples in containers of different shapes and volumes, at different speeds and in different orientations in space.

Abstract: In this invention we describe a magnet or magnetic material that is attached to a pipette to hang it on a ferrous or magnetic material. The magnet can be attached to any place on the pipette in such a way that the pipette can be hung as desired on the magnetic or ferrous surface such as ferrous clips, iron or steel sheets (refrigerator, lab bench, hood etc.). This will help to organize the laboratories. Furthermore this will reduce the contamination from pipette to pipette and sample to sample.
