Julabo SW Series Reciprocating Water Baths

Overview

The SW22 and SW23 Shaking Water Baths are ideal for routine applications, such as temperature control of samples, incubations, material testing, corrosion tests, cell cultivation, food and beverage testing.  The working temperature ranges from +20 to +99.9°C qualifying them for a wide variety of applications.

Features:

• Working temperature range from +20 to +99.9°C
• User-friendly operation via keypad
• Bright LED-Display
• Bath volumes from 2 to 26 liters
• Splash-proof design
• Power switch integrated in keypad (patented)
• High temperature stability of ±0.2°C (model SW22) or ±0.02°C (model SW23)
• Dry-running protection with audible and optical alarm
• Warning and cut-off protection for high/low temperature
• Adjustable shaking frequencies from 20 to 200 RPM‘s in SW models
• Convenient bath drains
• Removable bottom plate and shaking insert
• Lift-up bath cover (optional)
• Wide selection of accessories for temperature control of samples
• All wetted parts are made of stainless steel or high grade plastics

Julabo shaking water baths with seamless, splash-water protected keypad offer a high operating comfort. The bright LED multi-display indicating up to 6 temperature values is visible from across the lab. Advanced microprocessor technology with PID temperature control eliminates temperature overshoot and provides high temperature stability. The built-in timer simplifies time-dependent applications. The RS232 interface allows on-line communication with PC. Sensitive samples in the bath are well protected: As soon as the high and low temperature limits are reached an interval tone sounds. If the liquid in the bath reaches a minimum, a complete shut-down is effected and a permanent signal tone sounds. Instruments are conceived for unsupervised continuous operation. Bath tanks and all parts in contact with the bath liquid are made of high-grade stainless steel.
