To use the temperature control settings on the pump, you would need to plug the Heating Sleeve for Stainless Steel Syringes for the Chemyx Stainless Steel Syringes to use with the Fusion 6000 High-Pressure Syringe Pump (Legacy Product) and Fusion 6000-X High-Pressure Syringe Pump.
They are four heating syringe sleeve sizes for the stainless steel syringe: 10mL, 20mL, 50mL and 100mL.
The heating sleeves can heat up to 80°C. The minimum temperature is the room temperature of your environment.
Please note that larger syringes will take longer to reach the temperature, because of the larger heat capacity and larger surface area for heat loss.
