BioSan WB-4MS: for temperature stabilization for your laboratory.

The BioSan WB-4MS is a water bath thermostat. It is particularly suitable for scientific and medical or pharmaceutical purposes. It is used to precisely regulate the temperature of the liquid.

The main features

Up to 4 liters of water can fit in the tank. You can set any temperature between 25 °C and 100 °C. The control range is at least 5 °C above the ambient temperature, but not more than 100 °C. The thermostat has a timer sound signal and has a quiet motor.

The temperature can be set directly on the device. To 1/10 degree accuracy (0.1 °C) , the temperature can be stabilized and adjusted.

For this purpose, an integrated magnetic stirrer is available with a stirring speed range between 250 and 1 000 rpm. And you can attach one or two test tube racks to the water bath thermostat.

Are there other similar devices?

The manufacturer not only offers the WB-4MS, but also several other pure water systems.

  • Labaqua Trace: With this, an inorganic analysis is possible – up to 30 liters fit into the storage tank. The instrument weighs 24 kg.
  • Labaqua HPLC: With this water producer, the proportion of TOC in the water is particularly low. The object is particularly suitable for bioscientific activities (microbiology and molecular biology).
  • Labaqua Bio: The Labaqua Bio pure water system is also used in molecular biology. This model has a weight of 26 kilograms.

What does the model look like?

Let's get back to the WB-4MS. Those who see the object for the first time will be impressed by its modern appearance. A red button for switching on and off is located at the bottom right. The bottom is black, but the upper part of the case is white.

The display and control panel is light blue. Below the display are four buttons for controlling the processes. The interior is made of steel and plastic. Of course, the steel is stainless.

The device impresses with its easy setup and operation. It is not too big, so you still have space for other items on the work surface. In addition to the device, the delivery includes a power cable and several plugs. Optionally, various sample and microcentrifuge tubes can be included.

Special features in terms of technology

The LCD display has 2 x 16 characters. However, there is no cooling system. However, it is possible to run the instrument between one minute and 4 days at a time. There is a digital time setting .

The dimensions are 340 mm x 270 mm x 250 mm (width/height/depth). This provides a working volume of 235 mm x 135 mm x 110 mm. The device weighs 3.4 kilograms. It consumes between 2.6 and 6.0 amps of electricity, at a voltage of 100 to 230 volts – and at 50 to 60 hertz. BioSan makes the process easier for you by sounding a timer tone signal.
