JULABO SW22 Shaking Water Bath – Temperature-Controlled Laboratory Incubator Bath

The JULABO SW22 Shaking Water Bath is a laboratory temperature-control instrument designed for heating, incubating, and agitating samples under controlled conditions. Manufactured by JULABO, the SW22 combines a heated water bath with a mechanical shaking platform, allowing laboratories to maintain a selected temperature while continuously mixing or agitating compatible sample containers. This combination makes the instrument useful for research, biotechnology, pharmaceutical development, microbiology, biochemistry, and general laboratory applications.

The SW22 is designed for applications where both temperature stability and consistent sample movement are important. A water bath provides uniform thermal contact around compatible containers, while the integrated shaking mechanism promotes mixing and improves contact between samples and the surrounding bath environment. Depending on the experimental protocol, this can support sample incubation, extraction, dissolution, and other temperature-dependent laboratory procedures.

The instrument features a stainless-steel bath tank designed for laboratory use. Stainless steel offers durability and resistance to routine laboratory conditions when maintained according to the manufacturer's instructions. The bath accommodates a filling volume of approximately 8 to 20 litres, providing space for multiple sample containers depending on their dimensions and the installed shaking accessories. The usable bath opening measures approximately 50 × 30 cm, with an immersion depth of 18 cm.

The JULABO SW22 offers a working temperature range of approximately 20°C to 99.9°C when the appropriate cooling arrangement is installed. Without additional cooling, the standard working range begins at approximately 25°C. Temperature regulation is managed through microprocessor-based PID control, which helps maintain the selected setpoint during operation. The specified temperature stability is ±0.2°C under the manufacturer's stated conditions. This makes the instrument suitable for many routine incubation and heating procedures that require controlled bath temperatures.

The integrated shaking mechanism operates at adjustable frequencies from 20 to 200 revolutions per minute (rpm). The standard shaking stroke is 15 mm, with an extended 25 mm option available for certain configurations. Adjustable shaking allows the user to select an agitation level appropriate for the sample type, container format, and laboratory protocol. The removable shaking carriage helps simplify sample loading and removal, making it practical for routine laboratory workflows.

The SW22 includes a digital LED display and keypad controls for setting and monitoring operating parameters. Its electronic timer can be configured from one minute up to 9 hours and 59 minutes. These features support repeatable incubation procedures and help laboratories maintain consistent operating conditions across experiments. The instrument also incorporates high- and low-temperature warnings, protective shutdown functions, and dry-running protection with audible and visual alarms to help safeguard the equipment and samples.

In biotechnology and molecular biology laboratories, a shaking water bath can be used for warming reagents, incubating compatible samples, supporting selected extraction protocols, and preparing solutions that require both heating and agitation. In pharmaceutical research, it may support dissolution studies, temperature-dependent experiments, and sample preparation when the instrument's operating range and shaking characteristics meet the requirements of the method. In academic and industrial laboratories, it can be used for general incubation and mixing procedures.

The SW22 is also designed for convenient routine maintenance. The bath includes a drain arrangement to facilitate emptying and cleaning, while the shaking platform can be removed when required. The transparent cover shown in the photograph allows the bath area to remain covered during operation; the exact cover configuration and its inclusion should be verified against the supplied accessories.

Before use, operators should confirm that the selected bath liquid, sample containers, operating temperature, and shaking speed are appropriate for the experiment. For operation near or below ambient temperature, the manufacturer specifies the use of a suitable cooling coil or immersion cooler. Electrical supply requirements must also be checked against the unit's nameplate, since available voltage versions differ.

Overall, the JULABO SW22 Shaking Water Bath is a versatile laboratory instrument for procedures requiring simultaneous temperature control and sample agitation. Its stainless-steel bath, adjustable shaking speed, digital temperature control, programmable timer, and safety functions make it a practical choice for laboratories conducting routine research, testing, and sample preparation.
