The viscosity of a fluid is a parameter representing the internal friction of the flow. When adjacent fluid flows have different speeds, in addition to the collisions between matter particles, there is also a momentum exchange between them. The elements in the high-speed flow will increase the kinetic energy of the slow-speed stream and vice versa, the matter particles from the slow flow will inhibit the motion of the fast flow. The viscometer and visco-cups will determine the measured value of the solution.

pH is the measure of the activity (activity) of hydrogen ions (H +) in the solution and therefore its acidity or base. In aqueous systems, the activity of the hydrogen ion is determined by the electrolyte constant of the water (Kw) = 1,008 × 10−14 at 25 ° C) and interaction with other ions present in the solution. Because of this electrolyte constant, a neutral solution (the activity of hydrogen ions equals the activity of hydrogen ions) has a pH of approximately 7. Aqueous solutions with a pH value less than 7 are considered to be present. acidity, while pH values greater than 7 are considered to be alkaline. Testing of water samples instead of purple litmus paper is now available for more accurate results. Calibrate the pH meter with the standard pH solution
Chemical
Conductivity is the ability of an environment to allow the movement of charged particles through it, when there is force acting on them, such as the electrostatic force of an electric field. Movement can create electric current. The mechanism of this motion depends on matter. To obtain measurement values, we must use conductivity meter and conductivity calibration with conductive standard solution.
Chemical
Refractometer is also known as a concentration meter, photometer (or brix meter). It is used to measure concentrations of substances dissolved in water or in solution form. Refractometer is used a lot in life it is an optical instrument used to measure the concentration of water-soluble substances such as:
Measure salinity of sea, salt water.
Measure honey concentration and amount of water of honey
Measure the sweetness of soft drinks, juices, fruit juices.
Measure alcohol content, fermentation, wine, fermented juice
Chemical
Turbidity of water originates from the presence of a number of suspended substances that vary in size from rough dispersion to colloidal, suspension (size 0.1 - 10mm). In water, opaque substances are usually: clay, organic matter, inorganic, plants and microorganisms, including plankton.
Chemical
A gas detector is a device that detects the presence of gases in an area. This type of device is used to detect a leak or the content of a gas in the environment, when the gas is detected, it can create an audible alarm for operators in the area where the leak is located. Leakage occurs, giving them the opportunity to leave the area.
Chemical
The burette is a long glass tube, graduated by volume, the lower part of the baby's claws, with a valve and the end with a tapered tip. There are many different types and capacities (usually Bs of 2ml - 25ml capacity) are engraved on the tube body to the nearest 0.1 - 0.01 ml
Chemical
Pipettes or straws are common laboratory equipment in chemistry, biology and medicine, used to transport a volume of liquid. There are different types of pipettes with different precision and precision depending on the purpose of use
Chemical
The volumetric flask is used to measure liquid exactly to the desired volume and can be used for storage, preparation and preparation of chemicals for solution. The volumetric flask meets many laboratory standards and is widely used around the world.
Chemical
A cylinder is a device used for the purpose of quickly confirming a specified volume of solution for an experiment. It can be applied to laboratory samples or chemicals, solutions for the process of testing, analyzing, synthesizing samples in the laboratory.
