Water baths with circulation

Laboratory water baths with circulation

Precise heating of medical and chemical samples requires reliable equipment. Modern circulating water baths minimize the risk of errors, ensuring full repeatability of processes – the foundation of success in any laboratory. Stable conditions are guaranteed by the forced circulation of liquids, which is the responsibility of an efficient pump. It ensures the same temperature throughout the tank, thanks to which WSL solutions effectively replace older equipment.

Users can choose between the compact LWTc series (up to 26 litres) and the LWMc models with a capacity of up to 51 litres.

• precise maintenance of temperature throughout the tank thanks to circulation,
• safe operating range of devices up to 100°C,
• Availability of various variants with a capacity of up to 51 liters,
• robust design adapted to intensive use,
• the possibility of perfect adjustment of dimensions to the workplace,
• High accuracy essential for professional serial testing.

Forced circulation and temperature homogeneity

Forced liquid circulation is an advanced solution that effectively eliminates thermal layers and prevents dead zones inside the tank. This  ensures that the device maintains the same temperature throughout the volume of the medium, which is essential for processes that require the highest precision. Compared to traditional static baths, models equipped with circulation guarantee much higher stability of operating parameters.

The use of a modern circulation system and advanced control brings a number of benefits:

• elimination of unwanted temperature differences inside the device,
• the ability to perform precise calibration of the equipment,
• ideal conditions for accurate testing of liquid viscosity,
• the option of thermostating external systems thanks to the built-in pump,
• full repeatability of results regardless of the load,
• maintaining the highest standards of occupational

The heart of the entire system is  the PR-1 controller, which precisely supervises the operation of the device. It is this component that provides researchers with the necessary certainty and ensures that the variable load does not affect the quality and reliability of the measurements obtained.

Steel construction and PID temperature control

The interior of the device is made of high-quality stainless steel, which guarantees durability and resistance to corrosion and chemicals. Thanks to bathtub embossing technology, maintaining impeccable hygiene is much easier. Efficient  stainless steel tubular heater is responsible for efficient heating  .

• made of chemical-resistant stainless steel,
• pressed bathtubs to facilitate hygiene,
• efficient heating system with a tubular heater,
• thermal stabilization thanks to the PID controller,
• intuitive touch panel or LED display,
• Secure non-volatile memory to protect settings.

Advanced PID controller with NTC sensor eliminates temperature fluctuations, protecting biological samples. Operation is facilitated by the ability to program work steps, and the non-volatile memory retains parameters even after a power failure, giving full control over the process.

Shaking, cooling and multi-chamber baths

The choice of a specific model depends primarily on the nature of the research being conducted. Shaking baths, which integrate a stable temperature with mechanical movement, are the foundation for incubation and breeding processes. Depending on the requirements of the project, linear or orbital motion can be used, precisely adjusting the intensity of the vibrations. The safety of laboratory vessels, on the other hand, is guaranteed by universal handles that hold the flasks stably during operation.

Professional laboratory analyses use specialized solutions:

• baths with shaking integrating stable temperature with mechanical movement,
• multi-station models increasing the efficiency of mass evaporation of samples,
• viscometric and pycnometric devices for viscosity and density testing,
• laboratory equipment equipped with an additional cooling coil,
• Variants with magnetic stirrer for perfect fluid uniformity.

The use of a magnetic stirrer allows for full repeatability and reliability of results, which is essential in processes that require constant stirring. By ensuring perfect fluid homogeneity , the researcher can be sure that each step of the experiment takes place under controlled and optimal conditions.

The use of circulation baths in diagnostics

Modern medicine requires the highest precision, which is why circulation baths are its technological foundation, providing optimal conditions for conducting advanced research.

These devices are crucial wherever thermal stability directly determines the safety and reliability of laboratory processes.

• safe defrosting of plasma at a constant temperature of 37°C,
• precise incubation of cultures in clinical analytics,
• improvement of the preparation of tissue sections in histology,
• reliable verification of the stability of new drugs in pharmacy,
• maintaining thermal continuity in physicochemical experiments,
• Creating an optimal environment for microbiology testing.

WSL's innovative solutions use forced water circulation, which effectively eliminates the risk of sudden temperature jumps. This mechanism guarantees full repeatability of results and the highest reliability of each process, building modern standards in professional laboratory diagnostics.

Overheating protection and accessories

The user's safety is ensured by an advanced, multi-level security system. An independent hydraulic thermostat protects the device from overheating, and a precise electronic sensor constantly monitors the liquid level, which effectively prevents the heater from running "dry". In the event of an abnormality, the system instantly cuts off the power supply, informing you of the problem with clear audible and visual signals.

Everyday use is facilitated by a wide range of accessories made of corrosion-resistant materials. High functionality and safety of work are ensured by the following solutions:

• flat or gable cover adapted to the specifics of the tests,
• perforated shelf covering the heating elements,
• dedicated baskets and stands to facilitate the organization of samples,
• digital controller with timer for precise time management,
• built-in drain valve simplifying tank emptying,
• full compliance with European standards and CE certificate.
