This is a list of equipment suppliers for DIYBio FAQ: Projects.

In the United Kingdom


Brunel Microscopes Ltd has many years professional experience in all aspects of microscopy and specimen preparation. They stock a wide range of light microscopes, stereomicroscopes, accessories, prepared slides, stains and reagents that are suited to the professional and amateur microscopist, as well as educational establishments, industry and research.

Used Microscopes UK is a Brunel Microscopes website dedicated to preowned microscopes, accessories and ex-demonstration equipment.

Educational lab kits

Since its establishment in 1984-5, the NCBE has gained an international reputation for the development of innovative educational resources. The NCBE sells enzymes, microcentrifuges, pipettes, electrophoresis kits, transformers and other science kits.

In the United States of America

Chemical Suppliers

From the website: "Chemsavers is a distributor of laboratory chemicals. We stock many different types of chemicals and often hard to find and one of a kind chemicals. We offer below retail prices and free shipping. How can we do this? We make special purchases on sale items, bulk items and close outs. As far as most of the basic lab chemicals go, we keep them in stock as we purchase directly from the manufacturers to increase the savings to you"

Their international shipping policies are not known.

Cory Tobin notes: "Lab Depot sells pouches of pre-mixed TBE powder. For $22.71 you get enough to make 1L of 10x TBE. The usual working concentration of TBE is 1/2x, so this makes 20L of buffer. They don't mention only shipping to academic/commercial addresses so I suppose they will send the stuff to your apartment."

Culture Media

A recent question was asking where to find a supplier of amino acids for media. Sunrise Science Products ( is good, primarily focused on basic yeast media. They also ship to residential addresses. Likely better purity than one would find at a GNC type store where there is no assurance of the actual content of any bottle.

Educational and kit suppliers

From the website : "Here at American Science & Surplus we are fascinated by discovery and invention. And we are dedicated to having fun along the way. We offer an eclectic range of products, many with a science or educational tilt to them, others simply handy or amusing. Value is important, and whenever we can, we carry surplus at prices well below retail. We love closeouts, inventory overruns, mis-manufactures, and items whose time has not come.

A word of caution: When a surplus item is gone, it is gone. So if you see something you love, best get it now since we may not have it tomorrow. When we can't find surplus, we may carry regular merchandise which we think those interested in learning and tinkering will find appealing, but only if we feel it is good quality at a fair price."

Note: does NOT ship outside of US territories

Second hand online marketplaces was founded in 1995 to provide a forum where buyers and sellers of new, used, surplus, and refurbished scientific and laboratory equipment could find items, negotiate terms, and complete transactions online. LabX is a media service for the exchange of scientific equipment. We neither buy nor sell equipment, but rather provide a means for buyers and sellers to connect.

EBay sells, just about everything - including lab equipment

GOIndustry auction off stuff when companies go under. They usually have at least one ongoing sale of both large and small equipment, benches & cabinets, and glassware. There are a few catches, though. You may have to pick the stuff up - they won't automatically ship it to you.
