Urea, guanidinehydrogenchloride and Dithioerythritol are protein denaturants, and SDS (sodiumdodecylsulfate) and PEG (polyethylenglycol) as binders. Ammoniumtetramethylenedithiocarbamate[ATMDC], ammoniumpyrrolidonedithocarbamate [APDC], tetramethylammoniumbromide [TMAB] and pentaalkylammoniumbromidehexaethyl [PAABHE] surfactants are stronger protein denaturants. How do N, N' methyl urea derivatives behave in this context are yet to be investigated, so hydrophilic and hydrophobic interactions do ascertain a denauration mechanism. The densities (r/kg m-3), apparent molal volumes (Vf/m3mol-1), viscosities (h/N s m-2), surface tension (g/N m-1) and friccohesity (s m-1) of urea, 1-methylurea, 1, 3-dimethylurea and 1, 1, 3, 3-tetramethylurea illustrate molecular structures. The surface tension, friccohesity and viscosities are measured with Survismeter together. Limiting densities, apparent molal volumes, intrinsic viscosities and surface tension data infer solvent interactions. The partial molal volumes contributions of -CH3 are derived from the limiting data of ureas which notice weakening of hydrophilic and strengthening of hydrophobic interactions with the -CH3 numbers due to occupation of hydrogen bonding sites. The hydrophilic-hydrophilic interaction shift towards the hydrophilic-hydrophobic interaction from urea to tetramethylurea.

Viscosity describes a fluid's resistance to flow or change in form, essentially measuring thickness of a liquid in everyday terms. The higher the viscosity the slower an object can pass though it; likewise, the lower the viscosity the faster an object will be able to move though it.For example: You can move a spoon more easily though a bowl of water than through a bowl of honey. The water is less viscous (thinner) compared to the (thick) honey.
Kinematic viscosity is the ratio of dynamic viscosity to density of the fluid. The SI unit of the quantity is square meter per second (symbol m²/s). The most frequent used unit of kinematic viscosity is Centistokes (cSt). 1 Centistokes (cSt) is the kinematic viscosity of a fluid with dynamic viscosity of 1 cP and volumic mass 1 g/cm³.

0.7-1 mPa*s (or cP).
The survismeter measures osmolarity by developing a standard calibration between PCI (Physicochemical indicators such as viscosity, surface tension, friccohesity) and known values of osmolarity of some molecule.
Viscosity and surface tension of liquid sample are indispensable friccohesity chemistry. The water dipoles if are 100% aligned then cohesive forces are higher and viscosity comparatively could be lower. The water dipoles are haphazardly aligned with different cohesive and adhesive forces. The viscosity explain the interlaminar frictional forces as the haphazardly aligned molecules develop stronger interlayer interaction resisting a flow. For such haphazardly aligned liquid develop comparatively weaker cohesive forces or the lower surface tension. Therefore, the viscosity and surface tension work hand in hand and both are measured using survismeter. The sur stands for surface tension while the vis for the viscosity. The friccohesity gives a new physicochemical profile of molecular mixtures especially the nanoformulations. The friccohesity is calculated using the Man Singh equation. Their detailed understanding could be attained by going through the Survismeter and Friccohesity books
Survismeter, a laboratory apparatus, measures surface tension (ST), Interfacial Tension (IFT) and Viscosity together without any external forces like electric, magnetic etc. Vertical pressure gradient in vertical units of the survismeter works well to operate this instrument. The pressure gradient may manauly be developed using simple piston pump. The ST, IFT and viscosity are fundamental data to characterize the pharmaceutical formulations. So their availability together is an asset in the hands of pharmaceutical and biophysical scientists.The survismeter in single step process measures surface tension,interracialtension, viscosity, particle size and state of emulsions.Previouslyviscosmeter, tensiometer were used for these parameters but now survismeter is in use. There is saying that "those who don't run with wheel they remain there onlywhereverthey were so it is better to run with wheel of train so as to move with time andmaintainpace with fast developments"
Viscosity is a measure of a fluid's resistance to flow, while surface tension is the force that acts to minimize the surface area of a liquid. Viscosity affects how easily a fluid can flow, while surface tension affects how a liquid behaves at its interface with another material.
The pollutants in general, are chemicals which have well defined molecular structure with definite electronic configuration. Due to different kind of electronic profile, the molecules develop molecular forces which lead to initiate complex molecular, ionic, and mixed interactions which do not easily allow separation of the molecular mixtures. Their separation needs intensified and different treatment with improvised methods to reduce intake of pollutants. The survismeter and Econoburette are the equipments of the same kinds which reduce reuse recycle and redesion the chemicals being used in analysis for quality control and formulation of the end products. The survismeter measures surface tension, interfacial tension, wetting coefficient, viscosity and Friccohesity together while the Econoburette conducts titration using chemicals at semimicro scale. So both the equipments reduce intake and also prevent discharge of chemicals to environment.
Viscosity of a fluid is mainly influenced by the friction caused by the interactions between its molecules. Therefore a dishwashing liquid or reagent does not affect the viscosity of water, it only affect its surface tension. .
Surface tension was first described by Thomas Young in the early 19th century. He studied the behavior of soap films and water droplets to understand the forces at play on the surface. Since then, scientists have further explored the molecular interactions that contribute to surface tension and its role in various natural phenomena.
Time of students and resources of country are valuable and all efforts must be made to save and make smart use. Since inception of surface tension, interfacial tension, wetting coefficient, surface area and viscosity are being measured with individual apparatuses with manifolds wastages. There was no combination and permutation of the measuring devices for centuries but now Singapore and Indian Govts patents numbers 126089 and 232429 respectively offer survismeter for measurements together with 95% saving. The universities, technological institutes and R & D centers must take note of this invention in national interests and for fascination of science.

The viscosity is similar to the viscosity of water.
The term for the thickness of a liquid is viscosity. This property determines how easily the liquid flows and is influenced by factors such as temperature and composition. A high viscosity liquid is more resistant to flowing, while a low viscosity liquid flows more easily.
