biosan WB-4MS Stirred Water Bath

Safety precautions

• Caution! Make sure you have fully read and understood the present instructions before using the equipment. Please pay special attention to sections marked by this symbol.
• Caution! Hot surface! Platform surface becomes very hot during use. Always use protective cotton gloves to install or remove samples when the temperature is set higher than 60°C.
• Caution! Magnetism! Effects of a strong magnetic field on the biological systems have to be taken in to account. Magnetic fields can affect heart pacemakers, data carriers, etc.
• Caution! Do not use as heat transfer medium any other liquids except distilled water.

General safety

• Save the unit from shocks and falling.
• Store and transport the unit at ambient temperatures between -20°C and +60°C and maximum relative humidity of 80%.
• After transportation or storage and before connecting it to the electric circuit, keep the unit under room temperature for 2-3 hrs.
• Before using any cleaning or decontamination methods except those recom-mended by the manufacturer, check with the manufacturer that the proposed method will not damage the equipment.
• Do not make modifications in the design of the unit.
• If water steams away from the bath and the heating element is higher than 100°С, the thermostat automatically powers off. Add water to the bath only after cooling of the heating element.

Electrical safety

• Connect only to the mains corresponding to that on the serial number label.
• Do not plug the unit into an ungrounded power socket, and do not use an un-grounded extension lead.
• Ensure that the power plug is easily accessible during use.
• Disconnect the unit from the mains before moving.
• If the liquid penetrates into the unit, disconnect it from the mains and have it checked by a repair and maintenance technician.
• Do not operate the unit in premises where condensation can form. The operating conditions of the unit are defined in the Specifications section.

During operation

• Do not operate in environments with aggressive or explosive chemical mixtures. Please contact the manufacturer about the possibility of the operation in specific atmospheres.
• Do not operate the unit if it is faulty or has been installed incorrectly.
• Do not use outside laboratory rooms.
• Do not check the temperature by touch. Use a thermometer.

Biological safety

• The user is responsible to carry out appropriate decontamination if hazardous material spills on or penetrates into the equipment.

General information

Water bath-thermostat WB-4MS is designed for chemical, pharmaceutical, medical and biological laboratory research that requires maintaining a constant temperature from +25 °C to +100 °C.
WB-4MS provides increased temperature stabilization accuracy (up to 0.1°C) due to the built-in magnetic stirrer (stirring speed is regulated in the 250 to 1000 rpm range). Ease of setup and maintenance, high-temperature maintenance accuracy, compact size, and the innovative design of the water bath-thermostat meet the requirements of a modern laboratory.

Getting started

Unpacking. Remove packing materials carefully and retain them for future shipments or storage of the unit. Examine the unit carefully for any damage incurred during transit. The warranty does not cover in-transit damage. The warranty covers only the units transported in the original package.

Setup.

• Place the unit upon an even horizontal stable non-flammable surface 30 cm away from any flammable materials, and clear 20 cm around the device on all sides for ventilation.
• Connect the power cable to the socket on the rear side of the unit, and position it with easy access to the power switch and plug.
• Remove the protective film from the display.
• Place the magnetic stirring element at the bottom of the bath.
• Caution! A magnetic stirring element is made for stirring distilled water for uniformity of the temperature.
• Place the BP-1 platform at the bottom of the bath over the heating element.
• If necessary, place optional tube racks on the BP-1 platform. Do not place more than 2 tube racks at once.
• Fill the water bath with distilled water to cover the heating element (2-3 L).
• Caution! Turning the unit on when the heating element is not covered with water is strictly prohibited.
• Caution! If the protection from overheating is activated, switch off the unit and have unit checked by a repair and maintenance technician in accordance with the procedure specified in the Maintenance section.

Operation

Recommendations during operation.

• The water level in the bath should cover heating element. A user is responsible for monitoring of the water level in the bath.
• If water has steamed away from the bath, the unit should be switched off. Water may be added to the bath only after cooling of the heating element.
• We recommend covering the water bath with a lid if the temperature exceeds 50°C.
• Do not fill glassware over the level they are immersed in the water to ensure best temperature uniformity of the samples.
• Caution! Turning the unit on when the heating element is not covered with water is strictly prohibited.

Connect the power cord to a grounded power socket. Switch ON the Power switch situated on the front right lower side of the unit.

The unit will turn on and the following readouts appears on the display:

• Previously set time (fig. 1/2), set speed of magnetic stirring element (fig. 1/4) and set temperature of water (fig. 1/6) in the upper line (Set);
• Time indication (STOP, fig. 1/1), current speed of magnetic stirring element (fig. 1/3) and current temperature of water (fig. 1/5) in the lower line (Actual).
• Settings. Press the Select key (fig. 1/7) to choose the parameter to change. Each pressing of the Select key consecutively activates the parameters. The active pa-rameter is flashing. Use the ▼ and ▲ keys (fig. 1/4) to set required value. Pressing the key for more than 2 s will increase the increment.
• Temperature setting. Activate and set the temperature (T(°C), fig. 1/6). Heating starts. The actual temperature value appears in the lower line of the display (fig. 1/5).
• Magnetic stirring element rotation speed setting. Activate and set the rotation speed in rpm (RPM, fig. 1/4). The actual speed value appears in the lower line of the display (fig. 1/3).
• Time setting. Activate and set the desired time in hours and minutes (Time (hr:min), fig. 1/2).

Press the Run/Stop key (fig. 1/9) to start the timer. The elapsed time interval ap-pears in the lower line of the display (fig. 1/1).
After the set time interval elapses, the timer gives a sound signal and the flashing STOP indication will be shown on the display. Press the Run/Stop key once to stop the sound signal.

Caution! Stopping the timer does not stop the heating/temperature maintenance process. The heating can be stopped by reducing the temperature be-low 25°C using the ▼ key (fig. 1/4) until the OFF indication appears on the display.

• If the working time is set to 00:00, the unit operates continuously.
• To stop the timer before the set time interval elapses, if required, press the
• Run/Stop key. Press the Run/Stop key again, the timer starts counting the previously set time.
• After the thermal stabilization of the unit, e.g. when the set and current temperature readings become equal, open the water bath lid, place samples into the bath and close the lid.
• After finishing the operation, switch OFF the power switch. Disconnect the power cord from the electric circuit.
