Collection: Laboratory Water Circulators

Yamato Laboratory Water Circulators & Chillers

Yamato Scientific water circulators supply a steady source of temperature-controlled fluid to remove process heat — keeping rotary-evaporator condensers, viscometers, spectrofluorometers and reaction vessels at a stable set point. Every unit is a sealed closed-circulation system, so coolant is conserved rather than run to drain, and all are sold by LabSupplies.com as an authorized Yamato Scientific dealer, in stock and shipped from USA inventory.

The Yamato circulator lineup

• CB-100 — Benchtop Water Circulator, 3.4 L: the only model in the range with both heating and cooling (−10 °C to 80 °C). A slim 180 mm-wide footprint for viscometry, spectrofluorometry and general bench cooling/heating.
• CF-303Y / CF-313Y — Cooling Water Circulator, 3.9 L: compact refrigerated chiller, −20 °C to 30 °C, ~450 W cooling at 10 °C. Installs on or below the bench. Available in 115 V (CF-303Y) and 220 V (CF-313Y).
• CF-802A — Cooling Water Circulator, 16 L: high-capacity refrigerated chiller, ~1320 W cooling at 10 °C, that can serve up to four rotary evaporators at once, with an optional in-body solvent-recovery secondary trap.

How the models differ

Choose CB-100 when the application needs a regulated warm or cold bath and a small footprint. Choose the CF series for dedicated cooling: CF-303Y/313Y for a single rotary evaporator or condenser, and CF-802A when one chiller must cool a high heat load or several evaporators simultaneously. All three use environmentally responsible refrigerants and Pt100Ω temperature sensing with a white-LED digital controller.

For solvent recovery and concentration work, a circulator is most effective alongside a cold trap to protect the vacuum pump, and pairs naturally with a Yamato rotary evaporator. Not sure which circulator fits your load? See our Water Circulator & Cold Trap Buying Guide.
