Overview
The Sartorius Entris II BCA224I-1S is a current-generation analytical balance designed to provide reliable 0.1 mg weighing performance with a versatile 220 g working capacity.
That combination makes it an excellent general-purpose analytical balance.
While many analytical procedures involve relatively small samples, the total load placed on a balance includes both the sample and its container. Vials, crucibles, weighing bottles, flasks, filters, and other vessels can consume a significant portion of a balance's capacity before the sample is added.
The 220 g capacity of the BCA224I-1S provides additional tare flexibility while retaining conventional analytical resolution.
The Entris II Advanced platform also provides a substantial set of workflow and quality-control features, including automatic internal adjustment, leveling assistance, calibration-event documentation, user controls, electronic connectivity, and integrated applications.
Common Applications
The Sartorius BCA224I-1S is well suited for quantitative chemical analysis, pharmaceutical sample preparation, formulation, standards preparation, reagent weighing, gravimetric analysis, quality control, density determination, percentage weighing, differential weighing, filter weighing, residue analysis, and general laboratory research.
Pharmaceutical and biotechnology laboratories can use the balance for reference materials, formulation ingredients, research compounds, reagents, buffers, and routine analytical procedures.
Chemical laboratories can use the BCA224I-1S for standards preparation, solution preparation, compound weighing, quantitative analysis, and quality-control work.
Environmental laboratories may use the balance for filters, residues, particulate analysis, and other gravimetric procedures requiring 0.1 mg resolution.
Academic, food science, cosmetics, materials science, and industrial laboratories can also use the Entris II for a broad range of quantitative weighing procedures.
Ideal Laboratory Types
The BCA224I-1S is particularly well suited for pharmaceutical, biotechnology, chemical, environmental, analytical testing, academic, food and beverage, cosmetics, materials science, R&D, and quality-control laboratories.
Its combination of 220 g capacity and 0.1 mg readability makes it especially attractive as a general-purpose analytical balance in multi-user laboratories.
The larger capacity provides flexibility for laboratories whose sample sizes and weighing vessels vary significantly from one procedure to another.
For laboratories that routinely require 10 µg readability or very small minimum sample weights, a semi-microbalance may be more appropriate. When conventional 0.1 mg analytical resolution satisfies the method, however, the BCA224I-1S offers an excellent balance of sensitivity, capacity, speed, and ease of use.
Analytical Weighing Performance
The BCA224I-1S provides 0.1 mg readability throughout its 220 g weighing capacity.
Sartorius specifies repeatability of 0.1 mg and linearity of 0.2 mg.
Typical stabilization time is ≤1.5 seconds, allowing relatively fast repetitive measurements while maintaining analytical-level resolution.
This performance profile makes the Entris II appropriate for routine quantitative laboratory procedures where conventional analytical resolution is required.
Why 220 g Capacity Matters
Maximum capacity can be easy to overlook when selecting an analytical balance.
For many laboratory procedures, the actual sample weighs only a few grams. However, the balance must support the combined weight of the sample and its container.
A 220 g analytical balance provides significantly more flexibility for heavier tare vessels than a 120 g model.
This can be useful when weighing into larger glassware, sample containers, crucibles, bottles, or other vessels that consume a meaningful portion of the balance's working capacity.
The BCA224I-1S therefore provides the same 0.1 mg readability as lower-capacity analytical models while reducing the likelihood that vessel weight will become a limiting factor.
Minimum Sample Weight & Quantitative Applications
Readability and minimum sample weight are not the same measurement.
The BCA224I-1S displays mass in increments of 0.1 mg, but this does not mean that a 0.1 mg sample can be weighed quantitatively with acceptable relative uncertainty.
Minimum sample weight depends primarily on repeatability and the uncertainty requirements of the laboratory procedure.
For USP, GMP, GLP, or other controlled applications, laboratories should establish an appropriate minimum sample weight based on repeatability testing performed on the installed balance under actual operating conditions.
Environmental conditions, balance installation, vibration, airflow, static electricity, operator technique, and sample characteristics can all affect practical repeatability.
Controlling Drafts & Airflow
At 0.1 mg readability, air movement can produce visible changes in displayed weight.
The BCA224I-1S therefore incorporates a manual glass analytical draft shield around the weighing chamber.
The enclosure protects the sample and weighing pan from routine air movement caused by HVAC systems, doors, nearby personnel, and other laboratory activity.
The 240 mm weighing-chamber height provides room for a variety of laboratory containers and sample vessels.
The balance should nevertheless be installed away from direct HVAC outlets, fans, frequently opened doors, windows, and other strong sources of air movement.
Vibration, Temperature & Static Control
The BCA224I-1S should be installed on a rigid, stable weighing surface away from significant sources of vibration.
Centrifuges, shakers, pumps, compressors, refrigerators, freezers, and other laboratory equipment can transmit vibration through benches, floors, or surrounding structures.
Temperature differences between the sample and laboratory environment can also influence analytical measurements. Samples should be allowed to approach room conditions before critical weighing whenever the procedure permits.
Static electricity can become significant when weighing powders, filters, plastic containers, films, glassware, and other materials that readily accumulate electrostatic charge.
Appropriate antistatic techniques or accessories may be useful when static becomes a meaningful source of weighing error.
isoCAL Automatic Internal Adjustment
The BCA224I-1S incorporates Sartorius isoCAL automatic internal adjustment.
isoCAL uses an internal reference weight to automatically perform adjustment when defined time or environmental conditions indicate that adjustment is appropriate.
This helps maintain weighing performance as laboratory temperature changes throughout the day and reduces the need for users to manually initiate routine adjustment with external weights.
For an analytical balance operating at 0.1 mg readability, automatic internal adjustment can provide a meaningful improvement in convenience and day-to-day consistency.
External verification with appropriate reference weights may still be required under USP, GMP, GLP, ISO, or laboratory-specific quality procedures.
Real-Time Level Support
Proper leveling is essential for reliable analytical weighing.
The Entris II Advanced Line incorporates Real-Time Level Support to help users recognize when the balance requires leveling.
This is particularly useful in shared laboratories where an instrument may be cleaned, moved, or repositioned by different technicians.
The system provides additional operator guidance and helps reduce the possibility that measurements will be performed while the balance is incorrectly leveled.
CalAudit Trail
The Entris II Advanced platform incorporates CalAudit Trail functionality to support documentation of calibration and adjustment activity.
Maintaining a history of adjustment events can be valuable in laboratories operating under formal quality systems.
Rather than treating calibration as an isolated event, CalAudit Trail provides additional traceability around balance adjustment and performance.
This capability can be especially useful when multiple technicians use the same instrument or when weighing results form part of a documented analytical procedure.
Integrated Protection Systems
Sartorius Entris II Advanced balances incorporate protection features designed to help users recognize unsuitable operating conditions and reduce the risk of compromised results.
These systems provide additional guidance beyond simply displaying a mass value.
In busy or multi-user laboratories, integrated safeguards can help standardize weighing procedures and reduce dependence on operator experience alone.
Graphic Touch Display
The BCA224I-1S uses a graphic touch display for access to weighing functions, applications, configuration settings, calibration information, and system controls.
The interface is designed to make common laboratory weighing procedures straightforward while providing access to more advanced functions when needed.
For laboratories replacing older analytical balances, the modern interface can reduce operator training requirements and simplify routine method setup.
Built-In Applications
The Entris II Advanced platform includes integrated applications for common laboratory weighing procedures.
These include functions for weighing and dosing, counting, percentage weighing, mixing, totalizing, animal weighing, calculations, density determination, statistics, peak hold, checkweighing, and mass-unit conversion.
Underfloor weighing capability is also available for applications where a sample cannot be conveniently positioned on the normal weighing pan.
Built-in applications can reduce manual calculations and help laboratories perform repetitive procedures more consistently.
Connectivity & Data Transfer
The BCA224I-1S provides RS232 and USB-C connectivity for communication with compatible computers, printers, and laboratory peripherals.
Electronic data transfer can reduce reliance on handwritten results and manual transcription.
For laboratories processing significant numbers of samples, direct transfer can improve efficiency while reducing the possibility of transcription errors.
Connectivity also makes the Entris II easier to incorporate into increasingly digital laboratory workflows.
Underfloor Weighing
The BCA224I-1S supports underfloor weighing.
This allows an object to be suspended beneath the balance rather than positioned directly on the weighing pan.
Underfloor weighing can be useful for density determination, magnetic samples, oversized objects, and specialized research procedures where conventional pan weighing is impractical.

Choosing Between 120 g and 220 g Analytical Balances
The primary difference between 120 g and 220 g analytical balances is working capacity rather than resolution.
Both can provide conventional 0.1 mg analytical readability.
A 120 g balance can be entirely sufficient for laboratories that primarily work with small samples and lightweight vessels.
The 220 g BCA224I-1S provides an additional 100 g of capacity, allowing technicians to use heavier containers while retaining the same 0.1 mg readability.
For a general-purpose analytical balance that may be used across many procedures and by multiple departments, the additional capacity can provide valuable flexibility.
BCA224I-1S vs. BCA124I-1S
The BCA224I-1S and BCA124I-1S share the same basic analytical resolution and many of the same Entris II Advanced features.
Both provide 0.1 mg readability, isoCAL automatic internal adjustment, an analytical draft shield, Real-Time Level Support, CalAudit Trail, touchscreen operation, and electronic connectivity.
The major difference is capacity.
The BCA124I-1S provides 120 g maximum capacity.
The BCA224I-1S provides 220 g maximum capacity.
For laboratories whose total loads consistently remain below 120 g, the smaller model may provide everything required.
The BCA224I-1S is preferable when heavier vessels, larger samples, or greater tare flexibility are useful.
BCA224I-1S vs. BCA224-1S
Sartorius offers both internal- and external-adjustment versions of its 220 g Entris II Advanced analytical balance.
The BCA224I-1S includes isoCAL automatic internal adjustment.
The BCA224-1S uses external adjustment.
Both provide 220 g capacity and 0.1 mg readability.
The internal-adjustment BCA224I-1S is especially useful for laboratories that want automatic time- and temperature-responsive adjustment.
The externally adjusted BCA224-1S can be appropriate for laboratories that already maintain suitable calibration weights and prefer manual control over adjustment procedures.
Analytical Balance vs. Semi-Microbalance
The BCA224I-1S provides 0.1 mg analytical readability.
A semi-microbalance typically provides 0.01 mg / 10 µg readability, offering ten times finer displayed resolution.
Semi-micro performance can be valuable for small samples, expensive compounds, potent substances, reference standards, and methods with particularly demanding uncertainty requirements.
However, greater sensitivity also increases susceptibility to vibration, air movement, static electricity, temperature gradients, and operator technique.
For routine quantitative analysis, formulation, sample preparation, standards work, and quality control where 0.1 mg resolution is sufficient, the BCA224I-1S provides a practical combination of sensitivity, capacity, speed, and ease of use.
Entris II Advanced vs. Entris II Essential
Sartorius offers Entris II balances in Essential and Advanced configurations.
The Advanced Line represented by the BCA224I-1S adds workflow and quality-control capabilities intended for laboratories that want more than basic weighing functionality.
Features such as Real-Time Level Support, CalAudit Trail, integrated protection systems, expanded applications, and enhanced operator controls can be useful in multi-user or quality-controlled environments.
Laboratories primarily concerned with straightforward mass measurement may find an Essential configuration sufficient.
The Advanced Line becomes more attractive when weighing is part of a documented laboratory workflow.
