A practical guide to the sensible selection and procurement of basic laboratory equipment and consumables when resources are limited. Arguing that buyers get the best deal when they know as much, if not more, than the seller, the book sets out a wealth of guidelines and advice in the form of checklists, flowcharts, model forms and letters, equipment specifications, performance tests, and abundant tips and warnings. Information is addressed to laboratory staff who use, maintain, and repair equipment as well as to those who make purchasing decisions. Details range from tests for determining whether equipment lives up to its advertised claims, through a table showing the expected life of essential spare parts for a refrigerator, to tips for avoiding the tricks of high pressure selling. Throughout, the authors use a lively and engaging style to give readers the competence - and confidence - needed to make wise purchasing decisions. The book has eight chapters presented in three parts. Part one, on choosing and buying laboratory equipment, opens with a step-by-step guide to the factors to consider when making purchasing decisions. Particular attention is given to the role of quotations and the questions that should be asked when deciding which offer is best. Chapter two, on the buying business, explains the importance of suitability, reliability, timely delivery, and cost in the procurement process. Chapter three addresses common consumer problems, offering advice on when to lodge complaints and how to secure reimbursements for faulty equipment. Subsequent chapters outline the do's and don'ts of equipment care, describe the precautions to take when purchasing second-hand equipment, and offer guidance on the selection of minor equipment and consumables. The most extensive chapter, printed on yellow pages, is a 62-page buyer's guide to the selection of sixteen major equipment items for intermediate and peripheral laboratories. For each, information includes a quick reference guide indicating the questions to consider when making decisions, technical specifications and requirements, including spare parts, methods for testing performance, and a model form for assessing quotations. Part two covers energy sources and requirements, safeguards against power disturbances, and problems that may arise with specific energy sources, such as hand power, combustion powered generators, batteries, and solar energy systems. Additional reference tools are provided in the final part, which includes detailed examples of equipment data specification sheets; sample forms for ordering equipment, reporting problems, and securing quotations; advice on how to anticipate and avoid problems with donated equipment; precautions when ordering and transporting chemicals, reagents, stains, and dehydrated media; addresses of equipment manufacturers; and a list of non-profit and low profit suppliers of both second-hand and new equipment.
This volume updates and combines two National Academy Press bestsellers--Prudent Practices for Handling Hazardous Chemicals in Laboratories and Prudent Practices for Disposal of Chemicals from Laboratories--which have served for more than a decade as leading sources of chemical safety guidelines for the laboratory. Developed by experts from academia and industry, with specialties in such areas as chemical sciences, pollution prevention, and laboratory safety, Prudent Practices for Safety in Laboratories provides step-by-step planning procedures for handling, storage, and disposal of chemicals. The volume explores the current culture of laboratory safety and provides an updated guide to federal regulations. Organized around a recommended workflow protocol for experiments, the book offers prudent practices designed to promote safety and it includes practical information on assessing hazards, managing chemicals, disposing of wastes, and more. Prudent Practices for Safety in Laboratories is essential reading for people working with laboratory chemicals: research chemists, technicians, safety officers, chemistry educators, and students.

Now in its fifth edition, the book has been updated to include more detailed descriptions of new or more commonly used techniques since the last edition as well as remove those that are no longer used, procedures which have been developed recently, ionization constants (pKa values) and also more detail about the trivial names of compounds.In addition to having two general chapters on purification procedures, this book provides details of the physical properties and purification procedures, taken from literature, of a very extensive number of organic, inorganic and biochemical compounds which are commercially available. This is the only complete source that covers the purification of laboratory chemicals that are commercially available in this manner and format.* Complete update of this valuable, well-known reference* Provides purification procedures of commercially available chemicals and biochemicals* Includes an extremely useful compilation of ionisation constants
Prudent Practices in the Laboratory-the book that has served for decades as the standard for chemical laboratory safety practice-now features updates and new topics. This revised edition has an expanded chapter on chemical management and delves into new areas, such as nanotechnology, laboratory security, and emergency planning. Developed by experts from academia and industry, with specialties in such areas as chemical sciences, pollution prevention, and laboratory safety, Prudent Practices in the Laboratory provides guidance on planning procedures for the handling, storage, and disposal of chemicals. The book offers prudent practices designed to promote safety and includes practical information on assessing hazards, managing chemicals, disposing of wastes, and more. Prudent Practices in the Laboratory will continue to serve as the leading source of chemical safety guidelines for people working with laboratory chemicals: research chemists, technicians, safety officers, educators, and students.
The in-lab preparation of certain chemical reagents provides a number of advantages over purchasing various commercially prepared samples. This is especially true in isolated regions where acquiring the necessary substances from overseas can cause undue delay and inconvenience due to restrictions on the transportation of hazardous chemicals.
