Dynaflow® Resolve Temperature Control

The Dynaflow® Resolve Temperature Control (TC) system is an add-on to your Dynaflow Resolve system and enables reliable and fast ion channel recordings at elevated temperatures. With the Dynaflow Resolve TC system the recording temperature can be set anywhere between room temperature and 45°C, without the risk of temperature fluctuations following solution switch. Temperature control during ion channel research is especially important in studies of ion channel kinetics and in safety pharmacology applications.

Features

Temperature-controlled patch clamp experiments are greatly simplified with the Dynaflow® Resolve TC system. The system has been developed to enable the use of the Dynaflow Resolve chip for patch clamp recording at physiologically relevant temperatures, combining the features of controlled solution exchange and low substance consumption with precise temperature-control. The system consists of a temperature controller unit and a heat stage insert. As only one precisely controlled heat source is used, all 16 different solutions in a Dynaflow Resolve chip will have the same temperature, with no risk of temperature shifts when changing solution environment. The high performance of the feedback controller also ensures high temperature stability during the experiment even when running hour-long experiments

Benefits

  • Enabling recordings at room temp. to 45°C
  • Fast solution exchange capability
  • Stable recordings and excellent data quality
  • Minimal substance consumption

Assays

  • Safety pharmacology
  • Receptor kinetics studies
