  • Standard Operating Procedures
    Standard Operating Procedures 1 Standard Operating Procedures OVERVIEW In the following laboratory exercises you will be introduced to some of the glassware and tech- niques used by chemists to isolate components from natural or synthetic mixtures and to purify the individual compounds and characterize them by determining some of their physical proper- ties. While working collaboratively with your group members you will become acquainted with: a) Volumetric glassware b) Liquid-liquid extraction apparatus c) Distillation apparatus OBJECTIVES After finishing these sessions and reporting your results to your mentor, you should be able to: • Prepare solutions of exact concentrations • Separate liquid-liquid mixtures • Purify compounds by recrystallization • Separate mixtures by simple and fractional distillation 2 EXPERIMENT 1 Glassware Calibration, Primary and Secondary Standards, and Manual Titrations PART 1. Volumetric Glassware Calibration Volumetric glassware is used to either contain or deliver liquids at a specified temperature. Glassware manufacturers indicate this by inscribing on the volumetric ware the initials TC (to contain) or TD (to deliver) along with the calibration temperature, which is usually 20°C1. Volumetric glassware must be scrupulously clean before use. The presence of streaks or droplets is an indication of the presence of a grease film. To eliminate grease from glassware, scrub with detergent solution, rinse with tap water, and finally rinse with a small portion of distilled water. Volumetric flasks (TC) A volumetric flask has a large round bottom with only one graduation mark positioned on the long narrow neck. Graduation Mark Stopper The position of the mark facilitates the accurate and precise reading of the meniscus. If the flask is used to prepare a solution starting with a solid compound, add small amounts of sol- vent until the entire solid dissolves.

  • Laboratory Equipment Used in Filtration
    KNOW YOUR LAB EQUIPMENTS Test tube A test tube, also known as a sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom. Beakers Beakers are used as containers. They are available in a variety of sizes. Although they often possess volume markings, these are only rough estimates of the liquid volume. The markings are not necessarily accurate. Erlenmeyer flask Erlenmeyer flasks are often used as reaction vessels, particularly in titrations. As with beakers, the volume markings should not be considered accurate. Volumetric flask Volumetric flasks are used to measure and store solutions with a high degree of accuracy. These flasks generally possess a marking near the top that indicates the level at which the volume of the liquid is equal to the volume written on the outside of the flask. These devices are often used when solutions containing dissolved solids of known concentration are needed. Graduated cylinder Graduated cylinders are used to transfer liquids with a moderate degree of accuracy. Pipette Pipettes are used for transferring liquids with a fixed volume and quantity of liquid must be known to a high degree of accuracy. Graduated pipette These Pipettes are calibrated in the factory to release the desired quantity of liquid. Disposable pipette Disposable transfer. These Pipettes are made of plastic and are useful for transferring liquids dropwise. Burette Burettes are devices used typically in analytical, quantitative chemistry applications for measuring liquid solution. Differing from a pipette since the sample quantity delivered is changeable, graduated Burettes are used heavily in titration experiments.

    m A Simple Apparatus for the Study of Phototropic Responses in Seedlings. Geo. N. Hoffer. The purpose of this apparatus is to determine the minimum (piantity of light, acting as a lateral stimulus, that will produce a curvature response in seedlings of various kinds as well as some of the fungi, such as Fhj/comyccs and PUoJxAuh. Any kind of light may lie used, Iiut in the comparative studies I use direct sunlight. The <iuantity of liglit is regulated by opening and closing an iris diaphragm with various-sized apertures for definite lengths of time. The apparatus is made from a microscope carrying case. As shown in the photograph, Fig. 1, the outside attachments are the drawtube and rack and pinion of a microscope removed from the base and attached to one side of the box. Tlie tube works through a hole in the side of the box. The opening is made light proof by a velvet collar. Fig. III. \(\ glued to the rim and held to the tube of the scope by rubber I)ands. Into anotlu'r hole is Gttid a hemispheric, revolving iris diaphragm. Fig. Ill, I. This is on the adjacent side of the box close to the microscope and en the same level with the objective of the microscope. A mirror is at- tached to the box to reflect light directly into it through the iris and onto the plant. A micrometer eyepiece in tlie microscope is the index by which all of the readings are made. The illumination for the readings is supplied by the light which passes through the bottle, Fig.
