Razel Syringe Pumps

Razel syringe pumps have been available to researchers since 1968. During those 40 years the pumps have developed a reputation for affordability, reliability, and quality. In 2005 our company Mansfield Research and Development acquired Razel Scientific Instruments and continues to provide the scientific community with these accurate and dependable syringe pumps.

Infusion syringe pumps are widely used in many areas of research and industry. The Razel syringe pump line has been designed to cover a wide range of user needs. The pumps can operate manually, via computer, or on a timed infusion schedule. Syringe infusion rates of 0.00028 to 24 ml/min are possible depending on pump choice. All syringe pumps are designed to work with readily available syringes.

R-E The R-E syringe pump is outfitted with a single speed synchronous motor. With this setup, the speed of the motor determines the infusion rate for various syringes (5–50 ml capacity). Available motor speeds range from 0.008 rpm (0.017–0.603 ml/hr), to 20 rpm (0.688–24.122 ml/min). In its simplest form the R-E is a standalone pump operated by pressing an on/off switch. The R-ES option allows the user to operate the syringe pump via TTL pulses or switch closure. In this way, the syringe pump can be operated for set amounts of time via MED-PC® or other research tools. Other options for this pump include adapters to hold multiple syringes (R-ACC-Micro syringe adapter), and the R-DE option that has two pumps mounted on one base offering dual site synchronous infusion or use of an adapter that allows for five, 50 or 10 ml syringes to be used simultaneously (R-ACC-5, R-ACC-5/10ml respectively).
R99-E Researchers who need a pump that allows multiple infusion speeds without changing motors or syringe sizes should consider the R99 pump line. The R99 pumps have a built in wheel style flow chart that has 99 equally spaced pump speeds from 0.25 to 143 ml/hr when used with 5–50 ml syringes. A user simply selects the flow rate from the chart, inputs the corresponding number using a digital switch and begins infusing. Options are available for this syringe that allow the flow rate to be increased by 3 times (R99-EJ), or decreased to 1/10 of the normal speed (R99-EM). The R99-EJM model covers this entire infusion spectrum, providing rates from 0.025 to 430 ml/hr. The R99 pump line offers options for a single (R-ACC-Micro syringe insert) or multiple-micro syringe adapter (R-ACC-6), empty syringe alarms (R-Option-F), and a reversal switch option allows the pump to withdraw or infuse (R-Option-B).
R100-E In its standard form the R100-E pump allows users to set infusion rates, via digital switches, based on syringe manufacturer and size. An internal computer controls the infusion rate, and a convenient LCD display shows the infusion rate and syringe type used. This allows the user to select exact infusion rates from 0.025 to 430 ml/hr. Researchers who select the R100-EC option are provided with a USB interface and API software that allows control of 16 pumps. The software allows users to select flow rates on their computer, send on/off commands, set ramping infusion schedules, and select exact dose volumes. This pump is available with all options available for the R99 line, as well as remote operation using TTL or switch closure (R-Option-S).
Infusion Pump Control (IPC) Software for the R100 Syringe Pump The IPC software allows users all the functionality of the API software with a few added benefits. IPC can control up to 24 syringe pumps, users can easily enter cross sectional areas for syringes not currently available in the syringe library, and complete infusion protocols can be created. Infusion protocols can include ramped schedules from 0.01 to 430 ml/hr depending on the syringe type used. Steps can be added to protocols for pauses, withdrawals, and infusions. Each step can be designated with an initial and final flow rate, duration, or injection volume. This software is very useful for researchers who need multiple injection durations or volumes in designated time periods, or those who are managing many syringe pumps.
R-104A High/Low Speed Precision Microliter Syringe Pump Using high quality microliter glass syringes allows this pump to ensure precise, accurate delivery every time. This pump supports 10, 100, and 500 µl glass syringes. The pump has the ability to inject the entire syringe volume in a single injection at unprecedented speeds. This system can empty a 500 µl syringe in less than 400 ms. The pumps are USB controlled for ease of use.
PHM-102 Triple Infusion Pump If periodic infusions of animals in their home cages are of necessity for your research the PHM-102 should interest you. This pump allows researchers to provide timed infusions at equally spaced intervals for infusion of up to three animals concurrently. Just like the R-E pump, infusion speed and volume are determined by the single speed motor selected and syringe size used.
PHM-100VS Variable Speed Syringe Pump The PHM-100VS pump gives users the ability to vary the speed and duration of infusion using digital switches. Infusion times can range from 0.1 to 99 seconds in 0.1 second increments. The speed of injection is controlled by the unit’s stepper motor. There are nine available motor speeds allowing for injections rates from 0.017 ml/min to 24.122 ml/min. The pump is designed for syringes ranging from 1 ml to 50 ml. Users interested in the R99 pump line should also consider the PHM-100VS as it has a wider range of injection rates and allows injection duration to be pump controlled. •
