(DN Series) Constant Flow Syringes

Product Summary

Provides a constant flow rate from solution reservoirs regardless of varying solution height.

  • A simple design that's easy to use
  • Maintains constant head pressure from multiple solution reservoirs
  • Uses ordinary gravity feed for smooth, pulse free flow
  • Does not require bulky pressure systems or regulators
  • Enables reproducible flow rates
  • Compatible with Warner's modular syringe holders
  • Can be used with Warner's FR-50 flow valve

A common difficulty facing researchers when using a perfusion system is maintaining a constant rate of solution 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. The 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.

Constant Flow Syringes (DN Series)

 

When used in conjunction with Warner's FR-50 Solution Flow Valve, precise, sub-maximal flow control is easily achieved. Syringe reservoirs may be refilled without interrupting solution flow.Reservoirs are available in 5 to 60 cc volumes and can be used with Warner's MSH Series Modular Syringe Holder System.
