SLK 200

Desktop magnetic resonance equipment for measurement of oil or fat, moisture, fatty acid and protein content in different types of seeds, oils and food. Simultaneous, non-destructive and automated determination.

Industry Applications

Agriculture & Food

• Avocado
• Chocolate
• Dairy Products 
• Mayonnaise and Sauces
• Oil, Seeds, Grains and Oilseeds
• Olive


• Biodiesel and more


• Artificial, Synthetic and more fibers


The SLK 200 is capable of simultaneously analyzing the percentage of moisture, oil-fat, protein, oleic acid and main fatty acids in all types of samples.

*For the measurement of some parameters, it is necessary to add special modules to the equipment.
In just seconds you can see the results on your PC with an accuracy greater than 98%:
04” Oil and Moisture
12” Protein
20” Fatty Acids
The analysis does not affect or destroy the samples.
Intuitive and User-Friendly Software. With a short training allows the user to make their own measurements.
Through our unique assistance platform: Spinlock Online Help Desk® you will have the right support and after-sales service remotely.


Single Seed Sample Holder

Spinlock exclusive development for low signals with variable gain control. Made out of Teflon and aluminum and designed for more precise oleic acid measurements in seeds of different sizes. These Sample Holders are part of the Spinlock Single Seed System, created specifically for genetic work. Most importantly, samples are never destructed, being able to replicate them.

SLK AS 30 Automatic Sampler

Designed to automatically insert and remove samples, compatible with SLK 100, SLK 200 and SLK 1000 PM. The SLK Auto Sampler will pick up a bulk sample holder from a prepared set of samples, weigh it, and place it for measurement in the Spinlock equipment automatically. Capacity: 2 modules of 50 samples and scalable.

Grinder Mill

Stainless steel mill with enclosed motor for olive sample preparation at the laboratory. 220 VCA supply voltage, 1 HP power, 2850 revolutions per minute, 500 cm3 crushing capacity. Made of stainless steel. Includes opening safety switch. Includes filling hopper. Enclosed motor.
Grinder Mill

Bulk Sampler Holder

Designed to hold a volume of 37cm3, corresponding to 15 to 25 grams of sample. Different versions for different applications: Teflon and Glass.
Bulk Sampler Holder


Desktop magnetic resonance equipment (TD-NMR) for measurement of oil or fat, moisture, fatty acid and protein content. It makes simultaneous, non-destructive and automated determinations of these patterns.


Inside the box

The standard version of this equipment features the NMR Spectrometer, 2 bulk sample holders, the SLK software for measurement and a desktop PC.



Bulk sample holders, sample holders for unique seed measurement, software for measurement in other applications or samples, electronic scale to connect to NMR and PC.

SLK 200 Software

All Spinlock Software is developed entirely in-house, compatible with MS-Windows based computers to control the SLK 200 and visualize all results. Signals and measurements can be saved in a database which is then exported to .dat, .pdf and .xls type of files (MS-Excel). The SLK200 works with a USB port and can be connected to a desktop CPU or a laptop. And is updated regularly.


Spinlock offers 2 types of software


  1. Industrial / Commercial Software:
    Characterized for user-friendliness, does not require a qualified operator.

  2. Research Software:
    This allows full flexibility in operations. Permits programming any pulse sequence or NMR experiment. Request more information about Condor and Condor Lite by Contacting Us here.

Software is available in English and Spanish.
Specific requirements concern avoidance of introducing ferromagnetic tools or instruments inside the equipment as permanent damage may occur. Even though it may be located close to ferromagnetic materials, it is recommended to keep away (1 meter / 3 ft) elements that have magnets, antennas, electrical power transformers and other possible sources of electromagnetic interference.
Depending on the application. Generally, for Sunflower or Peanut the Oleic and Linoleic acid content measurement are unique advantages of the SLK 200.
Oil/Fat & Moisture content: 4 seconds.
Oleic/Linoleic: 20 seconds. However, Spinlock recommends using temperature “Stabilization Time” option activated which delays the measurement time to 3 minutes and 20 seconds.
It is recommended to clean the sample from ‘foreign matter’ as this should not be part of the weight, particularly for fat content measurement. However, nothing impedes the equipment from correctly measuring a sample with foreign matter. Chemically treated samples of sunflower for example can be measured. Sample grinding is not required for grain, the measurement is non-destructive, and samples are not altered during NMR measurements.
Room temperature should be controlled and stable at 25º C / 77º F.
It is preferred and recomended that the SLK 200 PC has internet access to allow for connection to Spinlock’s Online Helpdesk Service via remote desktop.
YES. The use of online UPS is recommended specially on remote field locations where atmospheric discharges can occur or the power line is not stable and clean thoughout the year.
Steady green.
Ambient or magnet temperature are outside the accepted range.
The SLK 200 in standard configuration will include: the NMR main body, 2 sample holders for bulk analysis, software for measurement and a desktop CPU (no monitor/keyboard/mouse and other peripherals included. Additionals might have been purchased like a static lab balance or single seed sampleholders.
Additional bulk sampleholders, Balance, Single Seed holders, SLK AS 30 Autosampler robot, Grider for Olives.
