Constant Flow Syringes

When using a perfusion system, a common difficulty facing researchers is maintaining a constant flow as the reservoir empties. In general, since head pressure is a linear function of column height, the change in volume of a 60 cc syringe as the solution reservoir drains can result in a 20% decrease in flow rate.

When using a perfusion system, a common difficulty facing researchers is maintaining a constant flow as the reservoir empties. In general, since head pressure is a linear function of column height, the change in volume of a 60 cc syringe as the solution reservoir drains can result in a 20% decrease in flow rate.
Warner Instruments is pleased to introduce a simple and unique solution to this common problem. Our new DN Series Constant Flow Syringes virtually eliminate changes in flow rate, normally to less than 1%. These reservoirs are designed to maintain a constant pressure on the syringe contents without resorting to a complex or bulky apparatus (such as a pressure system or regulator).
When used in conjunction with Warner Instruments’ FR-50 Solution Flow Valve, precise, sub-maximal flow control is easily achieved. Syringe reservoirs may be refilled without interrupting solution flow. They are available in 5 to 60 cc volumes and can be used with Warner’s MSH Series Modular Syringe Holder System, see page M141.
