For controlled cooling of 25 to 1000 ml flasks without using jacketed reaction vessels. Units allow active temperature control from +150 to −30 °C (depending on circulator specification).

• Compatible with all standard laboratory circulator or chiller systems and any standard magnetic stirrer or overhead stirrer
• Compatible with standard laboratory round bottom flasks
• Precise temperature control of cooling block or flask contents (depending on circulator used)
• Unattended operation allows for overnight cooled reactions
• Possible to programme and control cooling/heating ramp rates (depending on circulator used)
