The Value Leader in Quality Syringe Pumps For Over 40 Years.

Established in 1968, Razel™ Scientific Instruments has a long standing tradition of providing researchers high quality, dependable syringe pumps at an exceptional value. Located in St. Albans, Vermont, we design, manufacture, and support all of our pumps in our own facility so you can be sure that your pump will meet all of your requirements now and for years to come.

“Work Horse” Syringe Pumps

Known throughout the industry as “work horse” pumps, longevity has been a hallmark of Razel™ syringe pumps. It is not unusual for our pumps to remain fully operational for decades. This industry leading reliability is due to the use of quality materials and exacting construction techniques in the manufacturing of each and every pump. Stainless steel is used for all critical parts, including the feed rod and upper frame, and many of our pumps are housed in an aluminum case for additional durability.

Flexibility and Ease of Use

Beyond durability, each Razel™ syringe pump is designed with flexibility and ease of use in mind. Our fully adjustable variable speed pumps, like the R-100E, offer a variety of  infusion rates and accommodate numerous syringe sizes. Our economical single speed pumps (R-E and R-DE) feature a selection of motors that can be easily changed out to expand the number of available infusion rates. Razel™ has a pump to suit nearly every need and budget.

Support for the Life of Your Pump

At Razel™  we stand behind our products, and our team is available to our customers for the life of their pump. New pumps are backed by a one year warranty. If there is ever a question as to the operation or set-up of one of our products, customers can contact us at 802.527.2343 or through the Contact Us form on this website.

Razel Scientific Instruments became a part of Mansfield Research and Development in January 2005. Razel™ infusion pumps carry C.E. approval for laboratory use in Europe.
