In-line solution heating is the simplest and most effective method of warming perfusion solutions. The heater is connected to the chamber with a short length of tubing such that the warmed perfusate flows directly into the chamber bath. Depending on bath volume and other factors, in-line solution heating alone by it self may be sufficient for many applications.
In-line solution heaters from Warner Instruments are used to warm perfusate solutions as they flow into a chamber (such as our Imaging and Recording Chambers). Their small size allows for placement close to the chamber input allowing the perfusate to be warmed immediately prior to entry. The SH-27B is our rapid flow in-line solution heater. It is ideal for perfusion flows up to 10 ml/min while the SF-28 is recommended for applications requiring solution flow rates of less than 2 ml/min.
