Consult our Harvard Apparatus pump catalog for the complete list of available syringes models (there is a wide variety of size, volume, tips, etc.). Most of them fit Harvard Apparatus pumps.

• Plastic Syringes. Propose a wide range of models from the single us Monoject Plastic syring to the Becton Dickinson Pastic syringes and super syringes.
• Hamilton glass syringes are considered the industry standard for precision fluid delivery. Harvard Apparatus offers a broad selection of these precision syringes which, when combined with Harvard Apparatus syringe pumps, offer fluid delivery with unparalleled accuracy and precision. A variety of syringe terminations are available to interface with virtually any system or experimental protocol.
• Stainless steel syringes intended for high pressure applications with good resistance to most aggressive liquids.

Harvard Apparatus offers a broad selection of syringe pumps to suit almost every application. Syringe pump models have been expanded to include new innovative pumps with the widest range of flow rates and forces of any manufacturer.

Recent additions are the PHD ULTRA CP, capable of delivering flow at constant pressure, and the PHD ULTRA XF with force capability in excess of 1,000 lbs., ideal for high flow rates and viscous solutions.

With more than 100 years of success and a proven track record of designing and manufacturing high quality reliable syringe pumps, only Harvard Apparatus has the scientific depth and fluidics knowledge to recommend the right pump and accessories for your application. Our superior technical experts are available to assists you from start to finish. 

Harvard Apparatus invented the lead screw based syringe pump in the 1950´s and introduced the first microprocessor pump, the now legendary Pump 22, in the 1980´s. Our syringe pumps are so accurate, even at low flow rates, that they have become the standard for mass spectrometry calibration, animal infusion and anywhere accurate volumes must be delivered.

Our Pump 11 Pico Plus Elite is best suited for low rate studies ans small volume injections. It is ideal for applications including: Microdialysis, animal drug and nutritional studies, cellular injection, and more.

The pumps can be used with a wide range of accessories (Valves, connectors, Footswitches, alarms, syringe warmers…) for continuous delivery, “auto fill” functions, daisy chains or any other specific application requiring additional features.

With actual major health problems linked to food and drink intakes such as alcoholism and obesity, the search to define the role of brain and molecular mechanisms in regulating food and drink intake has taken on a new priority.

Knowledge in the field of animal energetics is largely based upon indirect calorimetry, which is estimation of metabolic heat production by the organism from measurement of indices such as oxygen consumption or carbon dioxide production.

Progressive-ratio (PR) schedules permit studying food-motivated behavior.

Self administration is a classical model of human drug-taking behavior and consists in establishing in rodents an operant conditioning of an instrumental response (nose-poke, lever pressure) to obtain a reward, according to a fix or progressive ratio.

The purpose of the Conditioned Place Preference test is to characterize the rewarding potential of a drug or other experimental condition.

Social transmission of food preference is a test that is used in rodents to assess memory processes as well as social interaction ability.

The delayed matching to position/non-matching to position tasks (DMTP/DNMTP) are used to assess spatial working memory. 

The recognition test is based on the natural tendency of rodents to investigate a novel congener instead of a familiar one.
