microflex™ LRF - The most powerful benchtop MALDI-TOF MS today

Benchtop MALDI-TOF MS with 15k resolution

The microflex LRF with 15k resolution in reflectron mode handles a wide range of analytical challenges and provides linear-reflectron based operating modes. It is easy to use with intuitive operations that are ideal for non-expert users and busy multi-instrument labs.

Food Adulteration

The world-wide financial impact by food adulteration is huge. With a fast but yet very affordable MALDI analysis e.g. olive oil and soy bean oil mixtures can be rapidly classified to determine adulterations.


Determine absolute molecular weight distributions of synthetic polymers up to 500 kDa. Analyse data with PolyTools or Polymerix (Sierra Analytics).

Quality Control

In quality control time to result is critical. Using the microflex LRF rapid analysis of lubricants can be achieved on semi-conductor devices or oligonucleotides.

Routine MS

Molecular weight determination in a general purpose mass spectrometry facility: fast results from the best benchtop MALDI system.

Efficient result generation

The design of the instrument maximizes up-time and performance. The proven robustness and ease of use of the microflex LRF is the result of various build-in technical features.

Increased mass resolution and accuracy

Highest resolution across an extended mass range is enabled by the ion source with its proprietary panoramic PAN™ pulsed ion extraction. The best mass resolution of a bench-top MALDI TOF is achieved due to an independent reflector power supply, the integrated high performance MCP detector and the high-precision digital analogue converters. 

Maximized up-time

The oil free vacuum system is fully integrated and noise reduced. The microflex LRF can be operated at a wide range of power supplies e.g. 110V or 240V. Stable ion generation is realized by a 60 Hz Fiber-optic laser delivery – this robust arrangement guarantees highest up-times also for multi-Instrument labs.

Flexibility and Sensitivity

The instrument’s design with its reflector and linear mode operation allows for highest flexibility for various analyte types, such as oligonucleotides, proteins and polymers. In linear mode the system can be run in positive and negative ion mode. The gridless design of the reflector enables unmatched sensitivity. Bruker’s proprietary AnchorChip™ technology further increases the sensitivity by a factor of 10.

microflex™ LRF -Technical details

The microflex LRF can be operated in positive and negative ion mode using the linear detector. The saturation free detector technology enables highest dynamic range and superior performance for high mass detection. Ion generation is achieved using a 60 Hz N2-Cartridge-Laser including variable power attenuator and UV optics The laser operates at 337 nm. The microScout™ ion source uses the exact dimensions of 1/4 microtiter plate with a medium area target plate (54 mm x 36 mm). The pumping system is fully integrated into the system and comprises a vacuum measurement and control unit as well as a 70 l/sec turbo-molecular pump and a diaphragm-pump.
