Low Temperature Bath PSL-1400 Series

HOME > Low Temperature Bath PSL-1400 Series

Constant temperature bath with magnetic stirrer PSL-1400・1810・2000

• For studying reaction conditions in environments from -80℃ to high temperatures

 

        

♦ There is no need to prepare dry ice, reducing both effort and running costs.

♦ Temperatures can be set from -80°C to 20°C for Model 2000, -80°C to 0°C for Model 1810, and -40°C to 0°C for Model 1400.

♦ PSL-1810 and PSL-2000 enable stable, long-term temperature control at -80℃ , which cannot be achieved with dry ice-acetone or ice.

♦ The bath uses vacuum insulation, providing excellent thermal performance.

♦ The solution in the reaction vessel is stirred by a powerful stirring bar and further mixed by an additional stirrer installed in the bath, ensuring uniform sample temperature.

♦ Improves temperature control by eliminating the instability of using dry ice.

 

• Comparison of temperature controls (PSL-1810)

A dry ice-acetone refrigerant enables rapid cooling but lacks temperature stability. The PSL-1810 model takes slightly longer to reach -80°C, but maintains highly stable temperatures thanks to its vacuum insulation.
