This 14500 INR worth vortex mixer by Neuation is just like any other variable vortex mixer used in a molecular biology lab. This too is used for mixing complex macromolecules such as carbohydrates, lipids, proteins, enzymes, dyes, antibodies etc. Preparing biological solution is a vital step in most molecular biology experiments. Whether you are making an enzyme-substrate solution or protein solution for protein estimation - you need to mix the solution homogenously in order to get accurate results. Vortex Mixer 4200 rpm does this at variable speeds ranging from 300 rpm to 4200 rpm. You just need to hold the microtubes and the centrifuge tubes on the vortex rubber and control the desired speed and time on the digital display. They are generally on and off touch based LED equipment which means you need to just touch the rubber vortex while the switch is on and it will work automatically. Similarly, it automatically stops once you withdraw touching the rubber vortex with the microtubes kept in your hand. Vortex Mixer 4200 rpm is a small equipment weighing less than 3kg and has a load bearing capacity of 500 gm which makes it useable both inside laminar hoods and cold rooms. Thus, it can be used to prepare biological solutions in all conditions, even in cryopreservation conditions.
