BIOTECHLIQUID CHROMATOGRAPHY DETECTORS

Analysis at the measurement site

The Biotech range of Runge Mikron Detectors consists of a photometer, a fluorimeter and a conductivity meter, all flexible and portable.

The product line has the following unique features:

Flexible

Light sources, filters and measuring can be adapted to changing tasks. Ideal solution for changing routine tasks, yet more affordable and compacter than a fully variable detector.

Upgradeable

Your detector grows in line with your requirements and/or budget. Start with one wavelength and then upgrade later.

Connective

USB-C connector for data and energy, drivers for Data Apex Clarity, SCPA ChromStar, SCPA PrepCon, LabVIEW, open Runge protocol for customized implementation.

Small

LED technology is what makes mikron possible.

Cool

Functions at 4°C (39°F), no waste heat.

Durable

At least 5,000 operating hours.

Thrifty

Under 2,5 W power consumption.

Non-toxic

No mercury vapour lamp.

Runge Mikron 31 photometer

Absorption photometer with two modular interchangeable LED light sources.

The mikron 31 is the photometer for changing routine tasks. If you are not dependent on spectra, you can opt for this small, light and affordable detector. With this device you take the detector to the measurement site and not vice versa.

It simultaneously takes measurements on one or two wavelengths (rapid scanning). Wavelengths can be selected from a broad range extending from UV-C to IR-A.

It can be used directly in chilled environments down to 4°C (39°F) and its optical design, with a reference channel, guarantees a high degree of accuracy with no external calibration.

Runge mikron 71 fluorimeter

Fluorimeter with modular interchangeable LED light sources and emission filters.

The mikron 71 pocket sized fluorimeter allows you to take the detector to the measurement task whether it is in the field, the laboratory or in a production plant.

The detector comes with fixed but exchangeable wavelengths for analyte excitation and emission.

Due to the LED light source, the detector can be used directly in a chilled setting at 4 °C (39°F) in bioanalysis. The reference channel ensures a high degree of accuracy with no external calibration.

Runge mikron 81 conductivity meter

Conductivity meter for medium and high conductivity values.

Due to its compact size the mikron 81 conductivity meter can be used at the measurement site. It has a broad measurement range from 0.002 to 500 mS/cm which can be adjusted even more accurately by selecting the appropriate measuring cell. Consistent precise and fast temperature compensation ensures automated temperature correction of the conductivity signal across the broad measurement range.

The detector can be operated in chilled environments down to 4°C (39°F) making it ideal for applications in biology, pharmaceutics and food industries.

The detector design allows for a wide flow rate range up to 1L/minute.
