3 Function
The Büchi Recirculating Chiller B-740 is a closed-circuit
cooler for use with rotary evaporators. The two models
are distinguished by their outputs. The 800 watt version
is optimal for cooling one laboratory rotary evaporator, the
1400 watt version is sufficient for cooling two rotary evapo-
rators. The 2500 watt version has enough cooling capacity
to perfectly fit to Rotavapor R-220.
The temperature range extends from -10°C to 20°C, alt-
hough heating is not possible. The B-740 regulates the
temperature to /- 1 K exactly. The desired value
is simply entered with two keys (UP and DOWN) and can
be easily read from the LCD display (desired and actual
temperatures).
The environmentally-friendly refrigerant R134a is used as
the refrigerating medium.
