Soil soil equipments and use (soil science)

soil lab equipment

1. Study about different types of glassware used in soil science lab

2. This presentation is prepared by- Venus Chourey (1 Year,1Semester) B.sc Agriculture Sant kabir college of agriculture and research station Kawardha,chhattisgarh ) SUBMITTED TO- Shree Ravishankar nag (Department of Soil science)

3. During soil practical classes,various instruments/mechanical tools and glass ware are used in the laboratory for experiments.Therefore , the following are the glass tools used during experimental work in the laboratory :- Conical flask Beaker Culture tube Petri dish Valumetric flask Distillation apparatus micro-slides Cavity Slides Cover slips (10) Pipette (11) Watch Glass (12) Funnel (13) Measuring cylinder (14) Cooplin jar (15) Desiccator

4. CONICAL FLASK Flask can be used for making solution or for holding, containing, collecting, or sometimes volumetrically measuring chemical, sample, solution, etc. for chemical reactions or other processes such as mixing, heating, cooling, dissolving, precipitation, boiling (as in distillation), or analysis.

5. BEAKER These cylindrical-shaped instruments have flat bottoms and usually a small beak or spout for pouring. Beakers are available in a wide range of materials and sizes ranging from one milliliter to several liters and are used to stir, heat, mix, measure, or dispense liquids.

6. PETRI DISH The Petri dish is used to cultivate microorganisms while separating them from airborne contaminants. They provide a controlled environment for the growth of these organisms, which can then be used for further study or soil organism testing.

7. CULTURE TUBE Culture tube is a glass or hard plastic tube that is always longer than it is wide. It can hold chemicals, fluids, microorganisms, or other substances used by scientists for various experiments.

8. VOLUMETRIC FLASKS The volumetric flask is used for measuring accurate volumes of liquid materials for laboratory experiments. They are favored when available because they are more accurate than graduated cylinders and beakers, which are other pieces of equipment that are used to measure liquids.

9. Distillation appartus Thre are three essential pieces of distillation equipment needed to carry out the process; Reboiler or Pot – Used to heat the source liquid. Condenser – The heated vapour is cooled back to a liquid state. Receiver Flask – The device into which the concentrate/distillate is collected.

10. MICRO SLIdes slide is a thin flat piece of glass, typically 76 x 26 mm (3 by 1 inches) and about 1 mm thick, used to hold objects for examination under a microscope. Typically the object is placed or secured (mounted) on the slide, and then both are inserted together in the microscope for viewing.

11. CAVITY SLIDES Cavity Slide size is 1" x 3" (25mm x 75mm x 1.3mm) thick. The diameter of the concave is 16mm. Made from premium quality clear glass. Edges are precision ground and polished.. It uses to hold slightly thicker objects, and certain samples such as liquids and tissue cultures.

12. Cover slips cover slips are made out of glass and are essential equipment for the lab. They can be used to keep solid specimens pressed flat, and liquid samples shaped into a flat layer of even thickness. They're approximately 0.13mm to 0.17mm thick.

13. PipeTTE pipette (sometimes spelled as pipet) is a type of laboratory tool commonly used to transport a measured volume of liquid, often as a media dispenser.

14. Watch glass A watch glass is a round, concave glass dish used for evaporation in soil practical lab. It can also be employed for weighing solids and as a lid for flask and beaker. They are mainly used to dry and weigh solid compounds and to cover containers such as TLC developing chambers.

15. funnels To channel liquids or fine-grained substances into containers with a small opening. Used for pouring liquids or powder through a small opening and for holding the filter paper in filtration.

16. Corpin jar A specimen jar, also known as a gas jar is a laboratory container used to store, transport, and examine solid or liquid specimens.

17. Desiccator Desiccators are specialized containers used to create and maintain a dry environment for storing moisture-sensitive items, such as chemicals, pharmaceuticals, and electronic components. They are typically made of glass or plastic and consist of main compartment with a removable lid and stopper. Desiccator is crucial to prevent moisture from entering the container.
