Heating Mantles
HEATING MANTLES 17-1000: STIRMANTLE The StirMantle adds electromagnetic stirring capability (50-750 rpm) to the Series TM heating mantle for spherical flasks. Heating and stirring are independent; choose either or both. Speed is easily adjusted by a single dial on the StirControl II. The StirControl II creates and synchronizes the magnetic field. Its stirring speed is extremely stable, even at 50 rpm, despite temperature or load. When restarting (as for removal and reinsertion of the flask), Glas-Col's exclusive "Synchrostart" feature maintains linkage between the field and the bar. At restart, the selected speed is reached in approximately 4 seconds. The StirControl II connects to the StirMantle by cord, so it may be placed outside corrosive hood atmospheres and is easily accessible.

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. Operation temperature range +4°С to +40°С (from cold rooms to incubators) at maximal relative humidity 80%.

Organic Techniques
ORGANIC TECHNIQUES Organic techniques Introduction Practical organic chemistry is primarily concerned with synthesising (making) organic compounds and the purpose of a ‘synthesis’ is to prepare a pure sample of a specified compound. Essentially, there are five steps involved: • preparation – the appropriate reaction is carried out and a crude sample of the desired product is prepared • isolation – the crude sample of the product is separated from the reaction mixture • purification – the crude product is purified • identification – the identity of the pure compound is confirmed • calculation of the percentage yield. Apart from the last, each of the steps entails a variety of experimental techniques and operations, and in what follows some of the more important ones will be described. While they will be considered from a practical standpoint, we will touch on their theoretical basis where appropriate. Preparation Most organic preparations are carried out in fairly complex assemblies of glassware. The glassware has ground-glass joints that allow the individual pieces to fit together tightly, thus eliminating any need for corks or rubber stoppers. Suppose we had to prepare a compound that required the reactants to be heated, which is generally the case in organic chemistry. Let’s look at the glassware needed. It is illustrated below and consists of a round-bottomed or pear-shaped flask and a condenser. 26 A PRACTICAL GUIDE (AH, CHEMISTRY) © Crown copyright 2012 ORGANIC TECHNIQUES The assembled apparatus is shown below with the condenser mounted vertically above the reaction flask. The reaction flask should be of a size such that when the reactants are in place it is about half full. -

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.
