PET relies on the use of tracers (i.e. biomolecules labeled with radionuclides) for imaging. Due to the short half-life of the radionuclides used, PET tracer production is typically performed right before an imaging event. Production of a PET tracer can be broken down into three major parts: production of the radionuclide, radiochemical synthesis of the tracer, and, lastly, purification, formulation and quality control testing of the tracer. Several groups, including our own, have looked into leveraging the benefits of microfluidics (reduced system size, finer control of reaction parameters, reduced reagent consumption) towards the production of PET tracers. -
Rotary Evaporator (Single/Dual Condenser Type)
Version : 2020 Rotary Evaporator (Single/Dual Condenser Type) USA-RE20-UL/USA-RE20D-UL USA-RE50-UL/USA-RE50D-UL Introduction Rotary evaporator produced by USA LAB Inc. is a new type of product developed by the company for many years of design and production experience. The laboratory instrument rotary evaporator is mainly used to continuously distill a large amount of volatile solvents under reduced pressure. In particular, the concentration of the extract and the distillation of the receiving liquid at the time of chromatographic separation can be used to purify the reaction product. The basic principle of a rotary evaporator is vacuum distillation, that is, under reduced pressure, the distillation flask is continuously rotated as the solvent is distilled. The company's after-sales service will accompany you from the date of purchase. Please refer to this instruction manual (operation manual) before using. If you have any questions, please feel free to contact us and we will do our best to serve you. TABLE OF CONTENTS 1. Working principle and scope of application 4 2. Precautions 4 3.

Laboratory Rectifying Stills of Glass 2
» LABORATORY RECTIFYING STILLS OF GLASS 2 By Johannes H. Bruun 3 and Sylvester T. Schicktanz 3 ABSTRACT A complete description is given of a set of all-glass rectifying stills, suitable for distillation at pressures ranging from atmospheric down to about 50 mm. The stills are provided with efficient bubbling-cap columns containing 30 to 60 plates. Adiabatic conditions around the column are maintained by surrounding it with a jacket provided with a series of independent electrical heating units. Suitable means are provided for adjusting or maintaining the reflux ratio at the top of the column. For the purpose of conveniently obtaining an accurate value of the true boiling points of the distillates a continuous boiling-point apparatus is incor- porated in the receiving system. An efficient still of the packed-column type for distillations under pressures less than 50 mm is also described. Methods of operation and efficiency tests are given for the stills. CONTENTS Page I.

By Angelo DePalma PhD Rotary evaporators are standard laboratory equipment found in nearly all laboratories. Chemical, pharmaceutical, food, and environmental industries are the most common users, but rotary evaporators, or “rotovaps,” may be found wherever processes require sample concentration or solvent distillation. All rotary evaporators include a heating bath, condenser, collecting vessel, and rotating sample or distillation flask. BUCHI Corporation (New Castle, DE), a leading manufacturer of rotovaps, still sells a large number of those simple units to academic and even industrial labs. But another world of rotary evaporation exists for laboratories that value application versatility, automation, and connectivity. “Our largest-volume market has been and remains pharmaceuticals, and they’re willing to pay for a high degree of automation, for many features that go beyond simple rotovaps,” says Jason Wagner, VP of marketing at BUCHI. “But there’s still a big market for stripped-down, no-frills models.” 3 A “full system” has a chiller to replace the use of cold tap water in the condenser unless dry ice is readily available. -

Building a Home Distillation Apparatus
BUILDING A HOME DISTILLATION APPARATUS A Step by Step Guide Building a Home Distillation Apparatus i BUILDING A HOME DISTILLATION APPARATUS Foreword The pages that follow contain a step-by-step guide to building a relatively sophisticated distillation apparatus from commonly available materials, using simple tools, and at a cost of under $100 USD. The information contained on this site is directed at anyone who may want to know more about the subject: students, hobbyists, tinkers, pure water enthusiasts, survivors, the curious, and perhaps even amateur wine and beer makers. Designing and building this apparatus is the only subject of this manual. You will find that it confines itself solely to those areas. It does not enter into the domains of fermentation, recipes for making mash, beer, wine or any other spirits. These areas are covered in detail in other readily available books and numerous web sites. The site contains two separate design plans for the stills. And while both can be used for a number of distillation tasks, it should be recognized that their designs have been optimized for the task of separating ethyl alcohol from a water-based mixture. Having said that, remember that the real purpose of this site is to educate and inform those of you who are interested in this subject. It is not to be construed in any fashion as an encouragement to break the law. If you believe the law is incorrect, please take the time to contact your representatives in government, cast your vote at the polls, write newsletters to the media, and in general, try to make the changes in a legal and democratic manner. -

Rotary Evaporator Fact Sheet
Rotary Evaporator Fact Sheet What are Rotary Evaporators? A rotary evaporator (also called as “rotavap” or “rotovap”) is a device used in labs for the efficient and gentle removal of solvents from samples by evaporation. The picture on the right shows what a typical rotary evaporator includes. What are Potential Hazards? • Burn hazard from heating water Source: bath (usually range from 25 – http://www.chem.ucalgary.ca/courses/351/laboratory/rotavap.pdf 95 °C) or cryogens used for cooling. • Implosion hazard from vacuum system. • Ignition hazard if flammable liquid vapors escape the apparatus or accumulate in the pump. • Inhalation hazard if toxic chemical vapors escape the apparatus. • Pinch point hazard from the motor unit and manual quick-action jack. • Entanglement with spinning parts. • Electrocution/shock hazard from the outlet. • Cut hazard from broken flasks. How to Work Safely with Rotary Evaporators? 1. Wear lab coats, eye protection (safety glasses or goggles), closed-toes shoes, and appropriate gloves while operating the equipment. 2. Tie back long hair and do not wear loose items to avoid entanglement. 3. Ensure that the apparatus is maintained in a good working order. Seals should be checked periodically and replaced as necessary. Decrease in vacuum and leaking are generally indications that seals should be replaced. 4. Use a vacuum source that is appropriate for the level of vacuum needed. Diaphragm pumps are appropriate for most applications. Belt pumps and rotary vane pumps provide high levels of vacuum that can cause excessive bumping (i.e., flash boiling of solvent) and clog traps. Water aspirators should not be used as these can allow solvent vapors to enter drains and waste large volumes of water. -

Some contaminating factors affecting diffusion pump performance were identified and explained, and some advances in vacuum distillation-fractionation tech- nology were achieved which resulted in a two-decade-or-more lower ultimate pressure. Data are presented to show the overall or individual contaminating effects of commonly used phthalate ester plasticizers of 390 to 530 molecular weight on diffusion pump performance.
