The Brr 20 with two optical ports and the Brr 30 with three optical ports provide temperature control and precision magnetic stirring for your sample. This product uses circulating water to cool the Peltier heat exchanger. Using room temperature water (~25 °C) it is perfectly suitable for everyday use from below 0 °C to 110 °C. Temperatures from 110 °C to 150 °C can be reached with the Extended Range versions. When very cold studies are desired, add additional windows and circulate ice water tp reach as low as -55 °C (no expensive Dewars or refrigerated baths required). Make your measurements in nearly any fluorometer or spectrophotometer.
