1. Overview


Syringe pumps are used in the field of scientific research to provide a reliable and repeatable method for moving liquids. Typically, the most common use of a syringe pump is to dispense a liquid at a known rate. This can be for use in processes such as pre-metered coating, automated systems, chemical synthesis, microfluidics, and flow chemistry. Other uses of syringe pumps include the withdrawal of liquids from a system for processes such as automated sample taking, and fluid level adjustment. By combining both infusion and withdrawal from syringes it is possible to use a syringe pump for an even wider array of applications including continuous flow of solutions, solution mixing, and the emulsification of solutions

A syringe pump works by fixing the barrel of the syringe to the body of the equipment while at the same time fixing the plunger to a moving platform. This movement is achieved via the use of a high accuracy stepper motor where the distance moved by the platform is well known and characterised. By knowing the internal diameter of the syringe being used it is possible to work out the volume displaced when the platform moves. The Ossila Syringe Pump provides you with a simple easily programmable system, where each program can have up to 99 different steps in which the rate, volume, and/or time of infusion/withdrawal can be chosen. By selecting the correct diameter syringe, it is possible to achieve flow rates as low as nanolitres per minute or as high as millilitres per second.

  • Modification or service has taken place by anyone other than an Ossila engineer.
  • The unit has been subjected to chemical damage through improper use.
  • The unit has been operated outside the usage parameters stated in the user documentation associated with the unit.
  • The unit has been rendered inoperable through accident, misuse, contamination, improper maintenance, modification, or other external causes.

3.7 Health and Safety - Operation

Pinch points warning symbol

Pinch point and entanglement hazards are present during operation of the syringe pump. As some precaution users should avoid handling or leaning over the equipment during operation in order to avoid possible crushing or entanglement of hair and/or clothing.

3.8 Health and Safety - Servicing

Electrical shock warning symbol

Service or installation work that includes integrating electrical components should be performed by an Ossila engineer only. Never alter the wiring of any purchased equipment. If changes are made, such alterations may damage the equipment, cause injury or death. At the very least, such alterations may void your equipment’s warranty.

4. Equipment Purpose


The Ossila Syringe Pump has been designed to provide users with a tool to move volumes of fluids accurately and repeatedly at specified rates. The equipment can be used in a wide variety of experiments where accurate dispense volumes and/or dispense rates are required. In order to achieve this, the system uses a stepper motor to enable movement of specified distances. This is done by securing the body of the syringe to the frame of the syringe pump while at the same time securing the syringe plunger to the moving holder. The internal diameter of the syringe can be used to determine the volume displaced by the movement of the stepper motor and plunger. By choosing the appropriate syringe size, a wide range of dispense rates can be achieved.

The exact syringe types, deposition rates, deposition volumes, and solutions used are up to the user to choose and will vary depending upon the type of experiment being undertaken. For more information on uses please see the operating instructions and guidelines, for more information on the dispensing limits please see the specifications.

9.2 Attaching a Syringe to the System

When using the Syringe Pump the following procedures should be done while attaching the syringe to the system to achieve the best results.

  1. The solution should be preloaded into the syringe; make sure all air bubbles are removed from the syringe before attaching to the system.
  2. The syringe barrel should be placed flat into the groove on the syringe holder, and the barrel top should be placed inside the clamping mechanism (see Figure. 9.2). The top clamping arm should be lowered onto the top of the syringe and locked into place by tightening the wing nut on the side of the syringe holder. The barrel top should be clamped into place by tightening the wing nut screws as the opposite end of the syringe holder.

10. Maintenance


The rail guide and the lead screw should be sparingly lubricated periodically; every 200 hrs of usage. The rail guide and the lead screw should be lubricated with super lube synthetic grease provided with the pump.

To clean the exterior surfaces, use a lint-free cloth to remove loose dust. Use care to avoid scratching the clear display window. For more efficient cleaning, use a soft cloth dampened (not soaked) with water, an aqueous solution of 75% isopropyl alcohol, or a mild detergent.
