In this chapter, two commonly used techniques that are utilized in many immunoglobulin purification schemes are described. The first procedure, ammonium sulfate fractionation, is generally employed as the initial step in the isolation of crude antibodies from serum or ascitic fluid ( 1 – 5 ).

A centrifuge is a piece of equipment that puts an object in rotation around a fixed axis (spins it in a circle), applying a potentially strong force perpendicular to the axis of spin (outward). The centrifuge works using the sedimentation principle, where the centripetal acceleration causes denser substances and particles to move outward in the ...

Celluloid centrifuge tubes are highly flammable and prone to shrinkage with age. They distort on boiling and can be highly explosive in an autoclave. If celluloid tubes must be used, an appropriate chemical disinfectant must be used to decontaminate them. Avoid overfilling centrifuge tubes to prevent closures from becoming wet.

A typical disk centrifuge stack contains 100 or more disks. The disks reduce the distance that a solid particle must travel before it is separated from the feed. Disk centrifuges range in diameter from 102-762 mm, and are capable of creating forces up to 14,000 times that of gravity. The two diagrams below show how disk centrifuges work.

Centrifuge - Vacuum, Separation, Purification: In the centrifuges described above, the rotor spins in air or some other gas at atmospheric pressure. The gaseous friction on a spinning rotor increases at a relatively high rate so that the power required to drive the rotor also increases rapidly. As a result, the temperature of the rotor rises drastically, sometimes …

Abstract. The influence of an additive (gelatin), impurity (antimony) or a combination of both gelatin and antimony on zinc electrowinning in sulphuric acid electrolytes was investigated by electrochemical noise measurements. This study was oriented to examine the utility of using electrochemical noise (EN) technique to …

A new technique for manufacturing single-barreled and double-barreled antimony pH microelectrodes is described. The results of investigations into the accuracy of antimony as a pH sensor disclosed that the pH-voltage response is: 1) within the physiologic range, principally the result of the hydrogen ion activity of the solution in which the ...

After letting the centrifuge rest for 30 minutes, 1) don your PPE, 2) use tongs to handle sharps, 3) remove sealed buckets and place in BSC, 4) disassemble and place other affected parts in disinfectant in BSC, 5) recover samples in BSC, 6) disinfect the bowl (if affected), 7) and follow all waste management guidelines for equipment and PPE ...

Centrifuges and Microcentrifuges. Centrifuges and microcentrifuges are commonplace in laboratories. They are used to separate solutions using the centrifugal force created by the rotor moving on a fixed axis. Successful sample centrifugation depends on the density, temperature, and viscosity of the sample and solution, and the speed of the ...

The plasma tubes were centrifuged at four different centrifuge settings and analysed for potassium (K +), lactate dehydrogenase (LD), glucose and phosphorus (Pi) at zero time, poststorage at six hours at 21 °C and six days at 2–8°C.At …

The term centrifuge can refer to a machine that houses a rapidly rotating container to separate its contents by density (noun) or to the act of using the machine (verb). Centrifuges are most often used to separate different liquids and solid particulates from liquids, but they may be used for gases. They are also used for purposes other than ...

As a centrifuge (Figure 1.90a) can spin up to 10,000 rotations per minute, an unbalanced load will cause the centrifuge to knock and wobble. If severely unbalanced, the centrifuge can even wobble off the benchtop, causing harm to anything in its way (they are heavy!). To prevent wobbling, every sample in the centrifuge needs to be balanced by ...

Centrifuge is a novel microbial classification engine that enables rapid, accurate, and sensitive labeling of reads and quantification of species on desktop computers.
