What is the Sartorius MSA1203S100DE?
The Sartorius MSA1203S100DE is a configured Cubis precision balance rated for 1,200 g x 0.001 g. It may be written as MSA1203S 100 DE, MSA1203S-100-DE, Sartorius Cubis 1203S, MSA 1203S or 1200 gram milligram balance. Keeping the full model code in the purchase request helps distinguish this MSA display and DE draft-shield configuration from other Cubis controllers and enclosures.
Published performance specifications
Sartorius catalog information lists 1,200 g capacity, 1 mg readability, approximately 0.7 mg repeatability, ±2 mg linearity and a 140 x 140 mm pan. The configured model uses isoCAL internal adjustment, motorized automatic leveling and a compact manual-door draft shield.
The 1,200 g capacity is a practical middle ground for laboratories that need milligram resolution with heavier containers or batches. For best results, calculate gross load using the container, closure, sample and any fixture. Do not select the model only from nominal sample mass.
Readability, repeatability and minimum weight
A balance can show a 0.001 g increment without every measurement being accurate to 0.001 g. Repeatability describes short-term scatter under stated conditions, while linearity addresses response across the weighing range. Minimum weight is application-specific and should be determined from repeatability, required relative uncertainty, applicable standards and a representative operating environment.
Using isoCAL correctly
isoCAL can initiate internal adjustment when defined time or temperature criteria are reached, helping manage sensitivity changes. It does not independently prove ongoing measurement fitness. Laboratories should define daily checks, control limits, periodic calibration and actions for failed checks, and should retain records appropriate to their quality system.
Why the draft shield still matters at 1 mg
Even at milligram readability, airflow can affect large containers and low-density samples. Close the DE shield doors gently, center the load and wait for stability. Avoid bench vibration, direct HVAC flow and sunlight; let warm or cold samples equilibrate; and reduce static on plastic vessels, films and powders.
1203S versus 3203S
The MSA1203S100DE and MSA3203S100DE both display 1 mg increments and use a 140 mm pan in the published configurations. The 1203S offers 1,200 g capacity and tighter published repeatability/linearity, while the 3203S increases capacity to 3,200 g. The lower-capacity model is not automatically better for every method; compare gross load, required uncertainty and service availability.
Applications
Potential uses include formulation, checkweighing small assemblies, standards preparation, material testing, loss-on-drying support, quality control and research where a larger analytical-balance capacity is useful. It is not a washdown scale or a default Legal for Trade device; confirm environmental and regulatory suitability separately.
What to verify on this discontinued model
Because this Cubis generation is discontinued, verify whether the unit is new old stock, refurbished or used. Request the serial number, condition report and recent performance data; confirm the MSA controller, weighing module, DE enclosure, pan, adapter and cables; test automatic leveling and isoCAL; and check firmware, communication ports, warranty, return rights, parts and local service. For regulated work, confirm that the documentation package can support qualification and audit needs.
Frequently asked questions
What is the Sartorius MSA1203S100DE capacity?
It is rated for 1,200 g with 0.001 g, or 1 mg, readability.
What repeatability and linearity were published for this model?
Legacy Sartorius catalog data lists about 0.7 mg repeatability and ±2 mg linearity for the configured model.
Does MSA1203S100DE include automatic leveling?
The listed 100DE configuration includes motorized automatic leveling as well as isoCAL internal adjustment.
What is the difference between MSA1203S100DE and MSA3203S100DE?
Both read to 1 mg, but the 1203S is rated to 1,200 g while the 3203S is rated to 3,200 g. Their published performance values also differ.
Is this a current Sartorius model?
No. It is a legacy Cubis configuration, so condition, parts, software and service support need explicit confirmation.
What should I ask for before buying?
Ask for the complete configuration, serial number, condition, included accessories, calibration results, warranty, return terms, firmware/interfaces and available service support.
