IKA RET control-visc white Magnetic Stirrer with Balance, Enamelled Heating Plate, 20 L, 0005030000

Anyone wishing to monitor not only the temperature and speed but also the weighed mass during a stirring process would normally need to set up a separate weighing module alongside the stirrer. The IKA RET control-visc white (0005030000) integrates a weighing function with a range of 10 to 5,000 grams directly into the heated magnetic stirrer, combined with a technical enamel work surface, a TFT display and a connection for pH measurements.

Integrated weighing function up to 5,000 grams

The weighing function covers a range from 10 to 5,000 grams with an accuracy of ±(0.3 per cent plus 2 grams); the maximum permissible load for the weighing function is 5 kilograms. This allows, for example, the quantity of a substance added to be checked directly at the stirring station, without having to transfer the vessel to a separate balance in the meantime.

Enamelled hotplate with high temperature accuracy

The round heating surface, with a diameter of 135 millimetres, is made of technical enamel and covers a heating temperature range from 0 to 340 degrees Celsius (room temperature plus self-heating), with a setting accuracy of 0.1 Kelvin at the plate, which is finer than that of most other models in the C-MAG and RCT series, which typically operate with an accuracy of 1 to 5 Kelvin. The maximum medium temperature with a connected probe is 270 degrees Celsius, and the heating power is 600 watts.

pH measurement and TFT display for process control

A pH electrode can be connected via a BNC socket, allowing the pH value to be monitored directly on the unit whilst stirring. All values, including setpoints and actual values for speed and temperature, are shown on a TFT display; a graph function is also available for the graphical representation of process trends. A disengagement detection feature alerts the user if the stirring bar loses its connection to the magnetic field.

Stirring up to 20 l with disengagement detection

The speed range extends from 50 to 1,700 revolutions per minute, adjustable in increments of 10 revolutions per minute; stirring rods from 20 to 80 millimetres in length can be used. A disengagement detection system alerts the user when the stirring rod loses its magnetic coupling with the drive, particularly useful for viscous or inhomogeneous media, where an unnoticed stoppage of the stirring rod would otherwise only be detected at a late stage. The maximum load on the base is 25 kilograms.

Typical applications

With its integrated weighing function, pH connection and high temperature accuracy, the RET control-visc white is technically suitable for:

• Titrations and dosing processes with direct mass control at the stirring point
• Syntheses requiring a temperature accuracy of 0.1 Kelvin at the hotplate
• Combined pH and temperature monitoring during stirring
• Processes with documented progress via the integrated graph function
• Stirring processes up to 20 l with varying viscosity, monitored via viscosity trend measurement

Selection guide: control-visc compared to other digital IKA stirrers

Within the range of digital IKA stirrers, the control-visc model offers the most comprehensive range of additional features, whilst providing the same stirring capacity as the IKA Plate (RCT digital):

If you do not require either a weighing function or a pH connection, the IKA Plate (RCT digital) or the C-MAG HS 7 control offer a more cost-effective solution. The additional cost of the control-visc version is particularly worthwhile if mass and pH value are regularly part of the documented process.

Differences from comparable IKA stirrers

The IKA Plate (RCT digital) offers the same stirring capacity of 20 l, but does not include a weighing function or a pH connection and features an aluminium base instead of an enamelled one. The IKA C-MAG HS 7 control offers a higher heating power of 1,000 watts, also without a weighing function. For applications with a similar range of functions, but without the special white finish, IKA also offers the RET control-visc in the standard colour.

Technical details

Scope of delivery

• 1 x IKA RET control-visc white magnetic stirrer with heating and weighing function (0005030000)
• 1 x PT 100.70 temperature probe
• 1 x IKAFLON 30 magnetic stir bar
• 1 x IKAFLON 40 magnetic stir bar
• 1 x screwdriver
• 1 x H 104 protective cover for RET control
• 1 x USB cable (USB-A to Micro-B), 2 m

Use, installation, maintenance and disposal

With an IP 42 protection rating, the RET control-visc white is protected against foreign bodies larger than 1 millimetre and dripping water when tilted up to 15°; according to the manufacturer, its sealed design is intended for long-term operation. The temperature of the installation surface rises by up to 17 Kelvin during one hour of continuous stirring; this should be taken into account when using the weighing function in the immediate vicinity of the heating plate, as heat can affect the measurement accuracy of external precision scales. The supplied H 104 protective cover provides additional protection for the control panel against splashes. At the end of its service life, as an electrical appliance, the unit must not be disposed of with household waste but must be placed in the separate collection for waste electrical and electronic equipment; the manufacturer’s WEEE registration number is DE 66784213.

Investment rationale: When the weighing function and pH connection are worthwhile

The additional cost compared with the IKA Plate (RCT digital) or the C-MAG HS 7 control is particularly worthwhile if mass determination and pH measurement are regularly part of the same process and a separate weighing module or pH metre would otherwise have to be set up, wired and calibrated at the workstation. For standard applications without weighing or pH requirements, the additional equipment is usually not necessary; in such cases, the more affordable digital or control versions without a balance are sufficient.

Individual requirements and procurement service

Additional original accessories for the RET control-visc white are available on request, such as pH electrodes, support plates, reaction blocks, oil bath attachments and replacement protective covers. Through our procurement service, we also assist you with spare parts, calibrations and the standardisation of equipment across multiple workstations.

Frequently Asked Questions

How accurate is the integrated weighing function?
The weighing range is from 10 to 5,000 grams with an accuracy of ±(0.3 per cent plus 2 grams); the maximum load capacity is 5 kilograms.

Is a pH electrode included in the Scope of delivery?
No, the BNC socket for connecting a pH electrode is provided, but the electrode itself must be purchased separately.

How does the ‘white’ version differ from the standard RET control-visc?
According to the data sheet, it is a standalone version in a different colour with its own data sheet; the core technical specifications are comparable to those of the standard model.

Can heating take place simultaneously whilst weighing?
The weighing function is designed as an integrated additional function of the stirrer; details regarding simultaneous heating or stirring are available on request.

Can the process progression be analysed graphically?
Yes, the TFT display offers an integrated graph function that allows temperature and speed curves to be monitored directly on the unit whilst stirring.

What interfaces are available for connection to a control system?
The RET control-visc white features an RS232 interface as well as a micro-USB port, via which the unit can also be connected to a control system.

Is a temperature sensor included in the scope of delivery?
Yes, a PT 100.70 temperature sensor is included; additional PT 1000 sensors can be connected for other applications.

How should the RET control-visc white be disposed of correctly?
As an electrical appliance, it should be taken to a collection point for waste electrical and electronic equipment rather than disposed of with household waste; the manufacturer’s WEEE registration number is listed in the section on ‘Application, Installation, Maintenance and Disposal’.
