Ossila have developed a new range of high-precision syringe pumps for the automatic dispensing of solutions. Our syringe pumps can deliver an accurate and continuous flow of volumes, ranging from nanoliters per minute to milliliters per second. With a simple-to-use design, this syringe pump accommodates almost any type of syringe (ranging in sizes from 50μl to 100ml). Our pumps can operate over a wide range of rates starting from as low as 1nl.s-1, up to nearly 0.5ml.s-1. For more information, please see our interactive syringe selection table.
Ossila's syringe pumps operate in both infusion and withdraw modes, giving you a high degree of user flexibility. Each syringe pump is individually programmable with the ability to save up to 20 different programs at once. Each program can contain up to 100 individual steps where the dispense volume, rate, and time can be controlled.
Syringe pumps (also known as syringe drivers) are used for the movement of fixed volumes of solutions at a specified rate, to deliver/remove a specific amount from a solution. This is achieved via the use of a motor that can either insert or retract a plunger from a syringe. By knowing the internal diameter of the syringe and the distance moved by the motor, the volume and rate at which a solution is moved can be calculated. Below are some examples of how single and dual syringe pumps can operate to give you a large variety of different functions. These include the infusion and withdrawal of liquids (either continuously or in a pulsing motion), the mixing of two different solutions into a single solution, or the continuous pumping of a single solution (via the use of check valves) to withdraw solution from a large reservoir.
Applications for syringe pumps include:
List of compatible syringes:
|Travel Per Revolution||1 mm|
|Steps Per Revolution||200|
|Travel Per Step||5 μm|
|Microsteps Per Step||64|
|Travel Per Microstep||78 nm|
|Minimum Speed||12 μm.s-1|
|Maximum Speed||5 mm.s-1*|
* Maximum speed can exceed this however this is dependent upon solution viscosity, syringe diameter, tube/needle diameter, and tube/needle length.
Below is a table which can be used to determine the minimum repeatable dispense volume, slowest continuous dispense rate, and fastest dispense rate for a given syringe size. The syringe diameters given for sizes ranging from 1 ml to 50 ml are for Norm-Ject disposable syringes which can be purchased here. If the size you require is not listed, you can enter in a custom diameter:
|Minimum Repeatable Dispense Volume:||nl|
|Minimum Dispense Rate:||nl.s-1|
|Maximum Dispense Rate:||μl.s-1|
Ossila's intuitive syringe pump software allows for the easy programming of complex multi-step experiments. The syringe pump can save up to 10 different programs with a total of 99 steps. Each step allows the user to select a dispense rate, a dispense time, and/or a dispense volume. Combining a colour LCD display, with a simple to use touch pad, and intuitive user interface the Ossila syringe pump allows for the rapid navigation through the options and settings letting the user quickly and easily set up and run new experiments.
The Ossila syringe pump allows the user to either set the syringe size from a range of preset sizes, or enter a custom size. Additionally, the maximum force provided can be controlled allowing the user to protect glass syringes from potential damage. A manual mode has also been added to allow the position of the syringe pump to be set up quickly for faster loading and unloading of syringes.
To the best of our knowledge the technical information provided here is accurate. However, Ossila assume no liability for the accuracy of this information. The values provided here are typical at the time of manufacture and may vary over time and from batch to batch.
