Macherey-Nagel NANOCOLOR VARIO C2 single thermoblock, 12 positions, 919350

For day-to-day work in water and wastewater analysis, a piece of equipment is needed that the laboratory team can rely on day in, day out – one that is robust, large enough to handle the usual sample throughput, and easy to operate. The Macherey-Nagel NANOCOLOR VARIO C2 thermoblock is designed precisely for this purpose: as a single-block unit with 12 positions, it covers day-to-day operations in sewage treatment works, environmental and contract laboratories, without the added complexity of a dual-block unit or the limitations of a small portable device. Unlike the portable or particularly high-performance models in the range, it is deliberately designed to strike a balanced compromise between capacity, ease of use and purchase cost.

12 positions for day-to-day laboratory work

The VARIO C2 accommodates up to 12 cuvette tests with an external diameter of 16 mm simultaneously and carries out the chemical digestion prior to photometric measurement. Six preset standard temperatures (70 °C, 100 °C, 120 °C, 148 °C, 150 °C, 160 °C) minimise operational errors in routine work, whilst six additional freely definable programme slots also cover individual or less frequently required digestion procedures without the need for a second instrument. The standard bore size of 16 mm is compatible with common NANOCOLOR cuvette tests, meaning that standard methods can be carried out directly without the need for special accessories.

Precise temperature range, user-friendly operation

The temperature range extends from 40 to 160 °C in 1 °C increments, with a stability of ±1 °C in accordance with DIN, EN, ISO and EPA methods. Compliance with these recognised test methods is particularly relevant for laboratories with a duty to provide evidence to regulatory authorities or clients, as it enables results to be documented in a traceable manner. Operation is via a backlit colour touchscreen with an icon-based menu in nine languages, including German, English and French, ensuring that even temporary staff or trainees can quickly find their way around.

Space-saving for everyday laboratory use

With external dimensions of 282 x 169 x 146 mm and a weight of 2,800 g (gross, including packaging), the VARIO C2 fits on any laboratory workstation without taking up valuable space at the fume cupboard or on the workbench. Its compact design also makes it easy to position next to a NANOCOLOR photometer, enabling a direct transition from digestion to measurement.

Network-ready and capable of data logging

RS232, USB-A and USB-B interfaces enable connection to PC systems and data exchange. Free software updates can be installed via the internet/PC or a USB stick. This simplifies both integration with existing laboratory software and the sharing of test reports as part of quality assurance. In combination with the optional NANOCOLOR T-Set (919917) or the USB version (919921), automatic calibration including a test certificate in accordance with DWA-A 704 is possible – an important component for internal quality assurance and for audits.

Reliable in everyday laboratory use

The VARIO C2 meets CE requirements and is designed for an ambient temperature range of 10 to 40 °C and a maximum relative humidity of 80 per cent (non-condensing), as required for continuous operation in everyday laboratory use.

Position within the NANOCOLOR VARIO range

In addition to the VARIO C2, Macherey-Nagel offers four further thermoblocks in the NANOCOLOR VARIO range: the portable VARIO Mini with 6 positions for use outside the laboratory; the VARIO C2 M with additional 22 mm bores for larger digestion vessels; the VARIO 4 with two independently controllable blocks and 24 positions for high throughput; and the VARIO HC with active cooling for shorter cycle times. For those who exclusively digest standard 16 mm cuvettes and find that 12 positions are sufficient for their day-to-day laboratory work, the VARIO C2 is the ideal central piece of equipment, without having to pay extra for specialised applications.

Typical areas of application

The VARIO C2 is the workhorse of the NANOCOLOR thermoblock range: designed for daily routine operation where a moderate number of samples need to be digested regularly, for example when a plant laboratory processes a fixed series of COD and nutrient samples every morning before the samples are analysed photometrically:

• Daily COD, total nitrogen and total phosphorus analysis in sewage treatment works and municipal wastewater treatment plants
• Routine digestion in in-house laboratories with their own wastewater monitoring
• Environmental and contract laboratories with a regular, predictable sample throughput
• Training and university laboratories as the central sample preparation unit for practical sessions
• Metal digestion and other photometric cuvette tests, in which up to 12 samples are digested in parallel
