• For low temperature synthetic reactions within the range of -80°C to 20°C
PSL-1400 PSL-1820 PSL-2000
♦ 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 1820, and -40°C to 0°C for Model 1400.
♦ Vacuum insulation is used for the bath, providing excellent thermal insulation performance.
♦ New insulation method enables continuous operation (PSL-1820).
♦ The solution in the reaction vessel is stirred by a powerful stirring bar, and further mixed by another stirrer equipped in the bath, so the sample temperature is kept precisely uniform.
♦ Improves temperature control by eliminating the instability of using dry ice.
• Comparison of temperature controls (PSL-1820)
Dry ice-acetone refrigerant enables rapid cooling but lacks temperature stability. The PSL-1820 model takes slightly longer to reach -80°C; however, it maintains a highly stable temperature due to its vacuum insulation effect.
• A user-friendly control panel that is easy to view and operate
PSL-1400 PSL-1820 PSL-2000
• Installed inside a fume hood
Compact design allows installation inside a fume hood.
