- 1. IMTIAZ ALI RIND REG: 2K17-SS-163 TOPIC: LABORATORY EQUIPMET & THEIR USES
- 2. ANALYTICAL WEIGHING BALANCE It is the laboratory instrument and use for precise determining mass of matter and Also used for weighing plant sample, fertilizer sample, soil sample and chemicals (powder forms) and we can weigh the material in milligrams to grams.
- 3. ATOMIC ABSORPTION SPECTROPHOTOMETER Spectrophotometer is a laboratory instrument use for determining many trace elements/ micro nutrients such as copper (Cu), zinc (Zn) Iron (Fe) Nickel (Ni) Manganese (Mn) , Molybdenum (Mo) etc. And also use for Determine the Heavy metals which are contaminate Air, Soil Environment, and Water Such as Cadmium (Cd) , Lead (Pb), Chromium (Cr) Selenium (Se) Arsenic (As) etc.
- 4. Fume Chamber / Fume Hood It is also laboratory instrument which is used for reduces exposure to hazardous fumes, vapors, gases and dust or other toxic substance when release solution preparation and hazardous chemicals can be also kept.
- 5. Oven An Oven provides a temperature higher than that of atmosphere and the temperature range covered by oven is b/w 50 0C - 250 0C, and these are used for rapid drying ,rapid moisture evaporation from material and for sterilization of articles that can be sterilized by dry heat specially in microbial laboratory.
- 6. ICP MS) Inductively Coupled Plasma Mass Spectrometer It is a multi elements analysis technique where the ICP sources convert the atoms of the elements in the sample to ions these ions are then separated and detected by the mass spectrometer and all kind of material can measure such as Francium (Fr) Radium (Ra) Actinium (Ac) Protactinium (Pa) Neptunium (Np) etc.
- 7. Magnetic Stirrer It is also laboratory instrument or device and also used for mixing two reagents or chemicals or used for dissolving or heating purpose because tow knob the left knob control the stirring rate and the right knob control heating.
- 8. pH Meter A pH meter is a scientific instrument that measure the hydrogen-ions activity in water –based solution ,it indicate acidity or alkalinity and it expressed as pH, It is measured on a scale of (0 to 14) .
- 9. Water Bath A water bath is a laboratory equipment made from a container filled with heated water, it is used to incubate samples in water at the constant temperature over a long period of time and it is also used when several tubes are to be handled while maintaining temperature of content.
- 10. Muffle Furnace Muffle Furnace is a vital testing instrument that is utilized in the laboratories for the test of different materials it is used for conducting the test that require a high amount of heat and it can reach a very high temperature up to a 9500 0C and it can be used in laboratories for performing the research about various properties of different material and also used for converting the material in absolute ashes ,this ash is used for performing the analysis of different attributes of the material that are being tested .
- 11. Flame Photometer An instrument used in inorganic chemicals analysis, used to determine the concentration of certain metal ions among them Sodium (Na) Potassium (K) Lithium (Li) Barium (Ba) Calcium (Ca)
- 12. Spectrophotometer A spectrophotometer is an instrument that measure the amount of light absorbed by a sample and it is used to determine the phosphorus in soil sample ,plant sample fertilizer sample and other elements are also determine by spectrophotometer such as sulfur ,Boron ,Nitrate-Nitrogen
