28. Hook pan is laboratory apparatus used to measure or carry weights. Some voltmeters help measure direct current (DC) circuits such as those found in batteries, while others measure alternating current (AC) circuits such as those found in home electrical outlets. To use these measurements to determine the areas of shapes and volumes ; To determine the density of water. Used in combination with agar to grow cells. Graduated Cylinder – a cylinder closed at one end and calibrated in the Metric system; used to measure the amount of liquid sample, never use it as a reaction vessel. There is a range of apparatus that National 5 Biology students must have knowledge of. Prev Question Next Question. Name Description Picture ; Beaker: Used to hold and heat liquids. The course also involves being able to describe and carry out experimental and measuring techniques. Modern microscopes can magnify objects to thousands of times their normal size. The balance has two platforms either mounted on or suspended from a cross-arm, and weights are placed on one platform until they balance the object being weighed. A triple beam balance is a kind of scale that gives an accurate reading of mass using three beams, each marked with different gram increments. )Triple beam balance- is a type of balance commonly used in the laboratory to determine the mass of samples. Alternative, Archimedes’ Principle can be used to determine the bulk volume of the core sample from the apparent weight change due to buoyancy when fully immersed. Wire Gauze Used to support a container, such as a beaker, on a ring stand while it is being heated. The apparatus is therefore capable of measuring the mass of an object to a precision of at least one tenth of a gram, which is probably good enough for most routine laboratory work. They are typically used to scoop a chemical out of its original container onto a weigh boat so that it can be weighed on a balance. Learn more. We used these tools to measure the thickness of a given number of pages of a textbook, the dimensions and volume of a lab table, the circumference of a brass cylinder and it’s weight. Nuclear density gauges measure density by measuring transmission through the soil of gamma radiation between a radioactive Cesium 137 (or other) source and Geiger-Mueller detection circuitry. The middle beam uses increments of 10 grams, while the largest uses increments of 100 grams. They allow humans to see structures, such as the inside of cells, which would otherwise be invisible. To weigh things using a balance. The bulk volume of the sample is the apparent volume change of the mercury in the pycnometer or graduated cylinder. When the pointer reaches its zero mark, the mass of the object being measured is ready to record. She has written about science as it relates to eco-friendly practices, conservation and the environment for Green Matters. Scientists can use voltmeters to measure the voltage of certain electrical reactions that may occur during experiments in their laboratories. Get scale calibration weights in three different sizes. The density is calculated by dividing the weight of gas by volume of measuring vessel. Centrifuge is used to separate precipitate from solution. They are also used to catch liquids from titrations and filtrates from filtering operations. To measure density of solids using a balance is an easy and convenient process that delivers highly reliable results when compared to other methods in which the volume of the part is determined independently of the weight. Bunsen burners are small gas burners that produce a single open flame. and used in the laboratory ... o measurement of boiling point with distillation apparatus o Siwoloboff method for small quantities o reliability of boiling point as a measure of purity. This causes a pointer at the end of the beams to move up and down with the changing weight. Kaplan SAT 2016 Chemistry II. Used to hold, mix or heat substances. Barometer is used to measure pressure.

The tools used for analysis may be subdivided into four categories: 1 Primary measuring equipment (pipettes, diluters, burettes, balances, thermometers, flow … Triple beam balance; Centigram balance; Platform balance; Analytical balance; TEMPERATURE. If the quantities of mass to be measured are very small (something weighing only a few milligrams for example), we will obviously need to use a more sensitive instrument. The smallest beam is the most precise, using increments of 1 to 10 grams. A meter that measures light intensity. Most modern voltmeters are digital and display the measured voltage as numbers on a small LCD screen. A device that uses lenses to magnify items that are normally too small for the human eye to see, e.g. Practice important Questions.
