Lab Equipment Erlenmeyer Flask
Lab Equipment Erlenmeyer Flask • Erlenmeyer flasks hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated. Beaker • Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated. Graduated Cylinder • A graduated cylinder is used to measure volumes of liquids. Test Tubes • Test tubes are used to hold small amounts of liquid and to conduct small chemical reactions in. Test Tube Clamp • A test tube holder is useful for holding a test tube which is too hot to handle. Test tube and beaker Brushes • Test tube brushes are used to clean test tubes and graduated cylinders. • Forcing a large brush into a small test tube will often break the tube. Test Tube Racks • Test tube racks are for holding and organizing test tubes on the laboratory counter. Plastic racks may melt in contact with very hot test tubes. Spot Plates • Spot plates are used when we want to perform many small scale reactions at one time. We will use these many times during the year. Watch Glass • A watch glass is used to hold a small amount of solid, such as the product of a reaction. Glass Stir Rod • A glass rod is used to manually stir solutions. It can also be used to transfer a single drop of a solution. Funnel • A funnel is used to aid in the transfer of liquid from one vessel to another. • A funnel is used to separate a solid from a liquid Wash Bottle • A wash bottle has a spout that delivers a wash solution to a specific area. -

MS-3000 and MMS-3000, Magnetic Stirrers
Magnetic Stirrers, Overhead Stirrer MS-3000 and MMS-3000, Magnetic Stirrers MS-3000 and MMS-3000 are compact magnetic stirrers with stainless steel working surface. Units provide stirring of liquids with rotation speed of magnetic element up to 3,000 rpm. Up to date it is the highest value of the maximal speed for magnetic MS-3000 stirrers of global producers. Strong magnets hold the driven magnetic element firmly in the magnetic clutch. Stirring is performed without undesirable heating and noise. Enclosures of stirrer MS-3000 are made of strong steel and DESCRIPTION painted with powder enamel, which is chemically resistant to acids and alkali. The stirrers are supplied with a cylinder-shape magnetic stir- ring bar (6 × 25 mm) encapsulated in PTFE for universal use. MMS-3000 is equipped with a detachable stand for supporting various sensor elements (temperature, pH and others) inside the stirred liquid. Magnetic stirrer is ideal laboratory instrument for PH-metering, extraction and dialysing with the small quantities of substances.

20 Pts. Chemistry Lab: Writing Chemical Equations I
Name(s): ________________________________________________ 20 Pts. Chemistry Lab: Writing Chemical Equations I. Purpose: To observe, predict, classify, and write balanced chemical equations that illustrate a chemical reaction. II. Procedure: 1. At each lab bench station follow the directions to perform the experiment. You must record all observations carefully. A significant portion of the grade is based on your ability to describe a chemical reaction in words as well as symbols. 2. Complete the rest of the table for each station's experiment. Classify as double displacement, single displacement, decomposition, synthesis, or combustion. Include phase notation in your balanced chemical equation. Clean up after each experiment. 3. Wear safety glasses! III. Analysis: Data: Station 1-a: Directions: Place 20 drops of ethyl alcohol in an evaporating dish. Cap and remove the bottle from the work area. Obtain a test tube that is dry on the outside and fill it 1/3rd full of cold water. Light a lighter and bring the flame close to the alcohol. Turn off lighter as soon as the alcohol ignites. With a test tube holder place the tube above the burning alcohol. Observe the outside of the test tube. Allow all of the alcohol to burn. Observation Classification Balanced chemical equation with phase not. Station 1-b: Directions: Place a scoopula of sodium hydrogen carbonate in a 150-ml beaker. Add 20-ml of vinegar (dilute acetic acid). Note the temperature of the beaker. "Pour" the gas (Not the liquid!) evolved from the reaction mixture onto the evaporating dish with the burning alcohol. Observation Classification Balanced chemical equation with phase not. -

LB Agar Plates with Antibiotic · Benchling LB Agar Plates with Antibiotic
10/7/2018 LB Agar Plates with Antibiotic · Benchling LB Agar Plates with Antibiotic Introduction In order to conduct transformation experiements, you need to create agar plates that have antibiotics to select the bacteria which successfully take up your plasmid. This protocol explains how to create said agar plates containing chloroamphenicol. Materials › Tryptone › Yeast Extract › Sodium Chloride › Agar › Don't mix this up with agarose › dH2O › 1 Liter Glass Bottle › Autoclave › Stock solution antibiotic (25 mg/ml) › Stirring plate and magnetic stirrer › 24 Petri Plates (90 mm) Procedure Creating the Agar Solution 1. In a large bottle (at least 1 L), add the following: Table1 A B 1 Amount Component 2 5 grams Tryptone 3 2.5 grams Yeast Extract 4 7.5 grams Agar 5 5 grams NaCl 6 Q/S to 500 mL dH2O 2. Shake until solutes completely dissolve file:///tmp/tmpRXrOGL.html 1/2 10/7/2018 LB Agar Plates with Antibiotic · Benchling 3. Place magnetic stirring bar inside the bottle 4. Stir (7/10) with heat (about 4/10) and wait about 15-20 minutes for the salt to dissolve. When the bottle is tilted, salt should not collect at the bottom. Sterilizing the Agar 5. Pour water into a beige plastic bucket to about 1 inch deep 6. Place bottle in bucket 7. Place bucket containing bottle into autoclave and run at 121°C and 20 PSI for a total of 35 minutes (20 minutes sterilize, 15 minutes exhaust) 8. Once done, use hot hands to take bottle out of autoclave (be very careful) and place on a stirring plate 9. -
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. -
