The Sartorius MA37 is designed for laboratories and production environments that need reliable routine moisture analysis without the complexity of a high-end method-development platform.
The instrument determines moisture using the thermogravimetric loss-on-drying principle.
A sample is placed on the weighing pan and its initial mass is recorded. The integrated infrared heater then dries the material according to the selected temperature and heating program while the weighing system continuously monitors changes in mass.
As water and other volatile components leave the sample, its mass decreases.
When the selected endpoint is reached, the MA37 calculates and displays the moisture result, dry-matter result, or another selected measurement format.
By integrating weighing and drying into a single instrument, the MA37 can substantially reduce analysis time compared with conventional oven loss-on-drying procedures.
The Sartorius MA37 can be used for routine moisture determination in food and beverage, pharmaceutical, chemical, plastics, agricultural, cosmetics, environmental, paper, manufacturing, and industrial quality-control applications.
Food laboratories can use the MA37 for ingredients, grains, flour, starches, powders, snack products, dairy ingredients, and processed foods where moisture affects texture, shelf life, processing, or product consistency.
Pharmaceutical and chemical laboratories can use the instrument for powders, granulates, raw materials, intermediates, and incoming quality-control testing.
Industrial laboratories can use the MA37 for polymers, paper products, agricultural materials, chemicals, and other production samples requiring rapid loss-on-drying measurements.
The MA37 is particularly well suited for quality-control laboratories, production facilities, incoming-material inspection, food manufacturers, chemical companies, pharmaceutical manufacturers, agricultural laboratories, educational facilities, and industrial testing environments.
Its rugged construction and straightforward interface also make it appropriate for locations where instruments are used by multiple operators throughout the day.
The MA37 is especially attractive for laboratories that want modern touchscreen operation and flexible endpoint settings but do not need to maintain a large library of stored methods.
The MA37 uses thermogravimetric analysis to determine moisture from changes in sample mass.
The instrument first records the starting weight.
Infrared energy then heats the material and causes water and other volatile compounds to leave the sample.
The integrated weighing system continuously measures the resulting mass loss.
Once the selected endpoint criterion has been reached, the analyzer calculates the moisture result.
This approach eliminates the repeated weighing, oven drying, cooling, and reweighing steps associated with traditional loss-on-drying methods.
For suitable samples, moisture results can often be obtained in minutes rather than hours.
The MA37 provides a maximum weighing capacity of 70 g with 1 mg resolution.
This offers twice the capacity of the MA35 while maintaining the same 1 mg weighing resolution.
Maximum capacity should not be confused with typical sample size.
Sartorius identifies approximately 5 to 15 g as a typical sample quantity for many MA37 procedures.
The 70 g capacity provides additional working range for heavier sample containers or specialized applications while still supporting the smaller sample quantities commonly used for routine moisture analysis.
The MA37 reports moisture results to 0.01%.
This is appropriate for a broad range of routine quality-control, production, and research applications.
Moisture resolution is different from weighing resolution.
The internal weighing system measures mass changes in 1 mg increments, while the analyzer calculates moisture results based on the relationship between initial mass and mass lost during drying.
Final result quality therefore depends not only on instrument specifications but also on sample size, preparation, drying temperature, endpoint selection, and material characteristics.
The MA37 uses a durable metal-tube infrared heating system.
Sartorius designed the heater to provide rapid and uniform drying while remaining robust enough for frequent routine use.
The heater operates at more than 480 W and provides a wider temperature range than the MA35.
Uniform heating is particularly important in moisture analysis because uneven sample temperatures can produce incomplete drying or inconsistent results.
The combination of a high-performance heater and optimized sample chamber allows the MA37 to deliver rapid results while maintaining consistent drying conditions.
The MA37 provides a drying-temperature range from 40°C to 200°C, adjustable in 1°C increments.
This is a significant improvement over the MA35, which is limited to 160°C.
The broader range allows the MA37 to accommodate materials requiring more aggressive drying conditions.
Lower temperatures remain available for heat-sensitive samples that could scorch, oxidize, decompose, or form a surface film during rapid heating.
Method development should always consider whether mass loss represents water alone or includes other volatile components.
Standard drying is appropriate for many routine samples.
The MA37 raises the sample efficiently toward the selected target temperature and maintains the defined drying conditions until the selected endpoint has been reached.
For stable powders, granulates, food ingredients, raw materials, and other conventional samples, standard drying may provide the fastest practical route to a repeatable result.
Gentle drying is designed for temperature-sensitive materials.
Instead of subjecting the sample to rapid aggressive heating, the analyzer approaches the selected drying temperature more gradually.
This can be useful for samples that scorch, form a crust, foam, oxidize, or otherwise react poorly to rapid heating.
A gentler heating profile may also improve correlation with an established reference method for certain products.
The MA37 includes an MA35 mode specifically designed to support migration from the earlier Sartorius MA35.
Laboratories that have already developed moisture methods using an MA35 can transfer those method parameters more easily to the MA37.
This backward compatibility can be valuable when replacing older instruments because it reduces the need to completely redevelop routine moisture-analysis procedures.
The MA37 therefore provides a logical upgrade path for laboratories already standardized around the MA35 platform.
The MA37 supports fully automatic endpoint determination.
During drying, the instrument continuously evaluates the rate of change in sample mass.
When the sample reaches the appropriate stability condition, the measurement can stop automatically.
This can reduce unnecessary drying time and simplify routine operation.
Automatic endpoint detection is especially useful in environments where technicians need a straightforward procedure with minimal manual decision-making.
For laboratories requiring greater method control, the MA37 also provides semi-automatic endpoint criteria.
The instrument can terminate analysis according to a defined mass change between 1 and 50 mg over a selected period from 5 to 300 seconds.
It can also use percentage-based criteria between 0.1% and 5.0%.
These options allow laboratories to tailor endpoint behavior to the drying characteristics of a particular material.
The MA37 supports fixed-time measurements from approximately 2 minutes to 99 minutes and 59 seconds.
Timed methods are useful when a standard operating procedure requires a predetermined drying duration.
Manual termination is also available when the user needs complete control over the end of the analysis.
The combination of automatic, semi-automatic, timed, and manual operation makes the MA37 substantially more flexible than a basic single-mode moisture analyzer.
The MA37 uses an intuitive touchscreen interface with guided menu prompts.
This simplifies temperature selection, endpoint settings, result configuration, and operation.
A streamlined touchscreen workflow can reduce training requirements and improve consistency across multiple operators.
This is especially useful in production or quality-control environments where the analyzer may be used by several technicians during different shifts.
A visible status light provides information about the current stage of the analysis.
This allows users to monitor instrument status at a glance without standing directly in front of the analyzer.
In laboratories or production areas where technicians may be running multiple tests at once, this simple feature can improve workflow efficiency.
The MA37 incorporates illumination within the sample chamber.
This gives users a clearer view of the material during drying.
Visual monitoring can be useful when working with samples that may discolor, scorch, bubble, foam, or otherwise change physically during heating.
Observing these changes can provide valuable information during method development.
Moisture analyzers frequently handle powders, liquids, food products, chemicals, and other materials that can contaminate the sample chamber.
The MA37 uses Sartorius's BetterClean design to simplify cleaning.
The hood and sample-chamber plate can be removed, allowing easier access to surfaces that may collect residue.
Sartorius also specifies that removable components can be cleaned in a laboratory washer where appropriate.
This can be particularly valuable in food, pharmaceutical, and industrial settings where contamination control matters.
The removable chamber hood incorporates a SoftClose mechanism.
Controlled closing helps reduce abrupt movement around the weighing system and provides a more refined sample-handling workflow.
It also helps protect the chamber mechanism during frequent routine use.
The MA37 includes Sartorius reproTEST functionality.
Used with a ReproEasy pad, reproTEST evaluates the combined behavior of the heating and weighing systems.
This is important because moisture-analysis performance depends on both components.
A calibration weight can evaluate weighing accuracy, but it does not confirm heater performance.
reproTEST provides an additional system-level check for laboratories that want to monitor analyzer consistency over time.
Sartorius specifies typical repeatability of approximately ±0.2% with an initial sample weight around 1 g and approximately ±0.05% with an initial sample weight around 5 g.
This illustrates how sample quantity can affect moisture-analysis precision.
Larger representative samples produce a greater absolute change in mass during drying, which can improve repeatability.
However, overly thick samples can dry unevenly.
For many materials, Sartorius identifies approximately 5 to 15 g as a useful working range.
Samples should generally be distributed evenly across the pan to promote uniform drying.

The MA37 is the logical next step up from the Sartorius MA35.
The MA35 provides 35 g capacity, while the MA37 doubles that to 70 g.
Both provide 1 mg weighing resolution and 0.01% moisture resolution.
The MA37 increases the maximum drying temperature from 160°C to 200°C and adds a touchscreen interface, gentle drying, MA35 mode, more flexible semi-automatic endpoint criteria, a status indicator, illuminated chamber, BetterClean design, and reproTEST functionality.
For laboratories purchasing a new analyzer today, the MA37 provides substantially greater capability while retaining a straightforward routine-workflow philosophy.
The MA37 and MA160 share several features, including 1 mg weighing resolution, 0.01% moisture resolution, a 40°C to 200°C temperature range, touchscreen operation, standard and gentle drying modes, MA35 compatibility, and reproTEST functionality.
The major difference is workflow complexity.
The MA37 stores a single active method and is intended primarily for routine analysis.
The MA160 can store up to 100 methods, retains the last 999 results, and includes the Method Development Assistant.
The MA37 is therefore a strong choice for laboratories performing a relatively small number of standardized procedures.
The MA160 becomes more attractive when many different materials must be tested and separate methods need to be stored and recalled regularly.
Traditional loss-on-drying procedures may require initial weighing, extended drying in an oven, cooling in a desiccator, reweighing, and additional drying cycles until constant mass is achieved.
The MA37 performs weighing and drying simultaneously.
Because mass is monitored continuously, the analyzer can recognize when the selected endpoint has been reached and provide the result immediately.
This can reduce analysis time dramatically for suitable materials.
Where a laboratory operates under a validated or standardized oven procedure, however, the MA37 method should be appropriately correlated before being substituted for the reference method.
The MA37 occupies a useful position within the Sartorius moisture-analyzer lineup.
It provides substantially more capability than the MA35 without introducing the extensive method-management features of the MA160.
For laboratories performing a limited number of recurring moisture tests, this can be an ideal balance.
The touchscreen interface simplifies operation, while the broader temperature range and flexible endpoints provide enough control to accommodate a wide variety of samples.
Its rugged metal-tube heater, BetterClean chamber design, and simplified workflow also make it well suited for production environments.
