Overview

The Mettler Toledo XS204 is a classic 220 g analytical balance with 0.1 mg readability, making it suitable for a broad range of routine and demanding quantitative laboratory procedures.

Its specifications place it squarely within the traditional analytical-balance category.

Compared with a general-purpose precision balance providing 0.01 g or 0.001 g readability, the XS204 offers substantially greater resolution for procedures involving smaller samples, tighter tolerances, standards preparation, gravimetric analysis, and quantitative chemistry.

At the same time, its 220 g capacity provides enough working range for many common laboratory containers, weighing papers, filters, vials, sample boats, and small vessels.

The Excellence XS platform adds features beyond simple mass determination, including automatic internal adjustment, touchscreen operation, built-in weighing applications, electronic connectivity, and a draft-shield system designed for high-resolution analytical work.

For laboratories seeking a proven analytical balance without requiring semi-micro or microbalance resolution, the XS204 remains a highly capable instrument.

Common Applications

The Mettler Toledo XS204 is well suited for standards preparation, pharmaceutical analysis, quantitative chemistry, gravimetric analysis, reagent preparation, formulation, sample preparation, filter weighing, quality control, density determination, percentage weighing, differential weighing, piece counting, and general analytical laboratory work.

Pharmaceutical and biotechnology laboratories can use the XS204 for reference standards, reagents, formulation ingredients, research samples, and routine quality-control procedures.

Chemical laboratories can use the balance for quantitative analysis, solution preparation, compound weighing, and research.

Environmental laboratories can use the XS204 for filters, residues, and other gravimetric procedures where 0.1 mg resolution is appropriate.

Academic, food and beverage, cosmetics, materials science, and industrial laboratories may also use the XS204 wherever high-quality analytical weighing is required.

Ideal Laboratory Types

The XS204 is an excellent fit for pharmaceutical, biotechnology, chemical, environmental, academic, food and beverage, cosmetics, materials science, analytical testing, research, and quality-control laboratories.

It is particularly useful as a general-purpose analytical balance in laboratories that perform a variety of quantitative procedures but do not routinely require 10 µg semi-micro or 1 µg microbalance resolution.

The combination of 220 g capacity and 0.1 mg readability provides substantial flexibility.

A laboratory can use the XS204 for relatively small analytical samples while still retaining enough working capacity for common containers and tare vessels.

For many facilities, this makes the XS204 an effective primary analytical balance.

Analytical Weighing Performance

The Mettler Toledo XS204 provides 0.1 mg readability throughout its entire 220 g weighing range.

Mettler Toledo specifies a repeatability limit of 0.1 mg at nominal load, with typical repeatability of approximately 0.04 mg under appropriate operating conditions.

At lower loads, the manufacturer's technical documentation identifies repeatability performance appropriate for analytical-balance work.

Linearity deviation is specified at ±0.2 mg.

The balance also provides an approximately 1.5-second settling time, helping support efficient repetitive sample weighing.

These specifications make the XS204 suitable for procedures requiring traditional analytical-balance performance without the increased environmental sensitivity associated with semi-micro or microgram-level instruments.

Minimum Sample Weight & USP Applications

Mettler Toledo specifies a typical USP minimum sample weight of approximately 82 mg for the XS204 under reference conditions.

The manufacturer also identifies a typical minimum weight of approximately 8.2 mg at 1% relative uncertainty.

These figures demonstrate why readability and minimum sample weight should not be treated as the same specification.

Although the XS204 displays mass in 0.1 mg increments, the smallest quantity that can be weighed quantitatively depends on repeatability and the uncertainty permitted by the laboratory's procedure.

For USP, GMP, GLP, or other controlled applications, laboratories should establish minimum sample weight based on the actual repeatability of the installed balance under its operating conditions.

Installation quality, environmental stability, calibration condition, operator technique, and sample characteristics can all affect actual minimum weight.

Controlling Drafts, Vibration & Static

At 0.1 mg readability, analytical balances are sensitive to environmental influences that may be insignificant when using lower-resolution precision balances.

Air movement, vibration, temperature gradients, static electricity, unstable work surfaces, and incorrect leveling can all influence weighing results.

The XS204 incorporates an enclosed analytical draft shield that helps isolate the SmartGrid weighing pan from routine laboratory airflow.

The balance should still be installed on a rigid, stable, level weighing surface away from strong vibration sources such as centrifuges, shakers, pumps, compressors, and refrigerators.

Static electricity can also affect samples such as powders, filters, plastics, films, glass containers, and weighing boats.

Where static becomes significant, appropriate antistatic procedures or equipment can help improve weighing stability.

FACT Automatic Internal Adjustment

The XS204 incorporates Mettler Toledo's FACT automatic internal adjustment system.

FACT uses an internal reference weight to perform automatic adjustment in response to defined operating conditions, helping maintain weighing performance without requiring the operator to manually place an external calibration weight on the pan for routine adjustment.

This is particularly valuable for analytical balances because environmental temperature changes can influence sensitivity.

FACT helps reduce the possibility that users will continue weighing after conditions have changed sufficiently to require adjustment.

Automatic internal adjustment does not eliminate the need for independent performance verification.

Laboratories operating under USP, GMP, GLP, ISO, or internal quality procedures may still require scheduled testing with appropriate traceable external reference weights.

American Instrument Exchange verifies FACT operation and externally tests weighing performance as part of the refurbishment process.

SmartGrid Weighing Pan

The XS204 incorporates Mettler Toledo's SmartGrid weighing pan.

Instead of using a conventional solid pan, SmartGrid reduces the surface area exposed to moving air within the weighing chamber.

This can help reduce turbulence and improve stabilization after the draft shield is opened to place or remove a sample.

The design is particularly useful during repetitive analytical weighing, where users may exchange samples frequently.

SmartGrid also allows spilled material to fall away from the primary weighing surface, making the weighing area easier to inspect and clean.

Draft Shield & Ergonomic Sample Access

The XS204 incorporates a fully enclosed analytical draft shield with approximately 235 mm of usable chamber height.

This provides room for a variety of sample containers, bottles, vessels, filters, and accessories while protecting the weighing area from surrounding laboratory airflow.

The XS analytical platform was also designed to allow convenient access to the weighing chamber from either side.

This can reduce awkward hand and arm movements during repetitive sample handling.

For laboratories performing numerous analytical measurements each day, these ergonomic considerations can improve workflow without compromising environmental protection around the weighing pan.

Touchscreen Operation & Built-In Applications

The XS204 uses a touch-sensitive graphical terminal rather than a basic segmented display.

The interface provides access to weighing functions, applications, balance settings, and system information.

Built-in applications include functions for:

  • Normal weighing

  • Statistics

  • Formulation

  • Density determination

  • Percent weighing

  • Piece counting

  • Dynamic weighing

  • Laboratory data-management workflows

These applications allow the XS204 to support considerably more than simple mass determination.

For laboratories performing repetitive quantitative procedures, integrated functions can reduce manual calculations and help standardize routine weighing workflows.

Connectivity & LabX Compatibility

The XS204 includes an integrated RS232C interface for connection to compatible laboratory computers, printers, and peripherals.

The balance also provides a slot for an optional additional interface, allowing connectivity to be adapted to laboratory requirements.

The XS platform can also be used with Mettler Toledo LabX software.

LabX can support electronic collection, calculation, storage, and reporting of weighing data when appropriately configured.

Electronic data transfer can reduce handwritten transcription and improve consistency in laboratories performing large numbers of routine analytical measurements.

Choosing Between an Analytical and Semi-Micro Balance

The XS204 provides 0.1 mg readability, which is the traditional resolution associated with laboratory analytical balances.

A semi-microbalance commonly provides 0.01 mg / 10 µg readability, making it ten times more sensitive.

That additional sensitivity is useful for smaller samples, tighter uncertainty requirements, reference materials, and applications where reducing sample consumption is important.

However, increased sensitivity also increases susceptibility to vibration, airflow, static electricity, temperature changes, and operator technique.

For routine quantitative chemistry, standards preparation, reagent weighing, formulation, and general analytical work, the XS204's 0.1 mg readability is often entirely appropriate.

A semi-microbalance becomes preferable when the application specifically requires measurements below conventional analytical resolution.

XS204 vs. XS204DR

The XS204 and XS204DR are different balances despite their similar model names.

The XS204 is a single-range analytical balance providing 0.1 mg readability throughout its entire 220 g capacity.

The XS204DR uses a DeltaRange architecture, with a different combination of full-range and fine-range readability.

This distinction is important when purchasing used laboratory balances because specifications for the XS204DR should not be transferred to the XS204.

For laboratories that want consistent conventional analytical resolution across the entire weighing range, the XS204's single-range architecture is particularly straightforward.

XS204 vs. XS105

The XS204 and XS105 serve different high-resolution weighing needs.

The XS204 provides 220 g capacity with 0.1 mg readability.

The XS105 provides substantially finer 0.01 mg / 10 µg readability but with a lower 120 g maximum capacity.

The XS105 is therefore better suited for procedures requiring semi-micro-level resolution.

The XS204 is better suited for laboratories that need conventional analytical resolution while benefiting from nearly twice the maximum capacity.

The right choice depends on whether the application prioritizes higher capacity or finer resolution.

Refurbishment & Performance Testing

Every used Mettler Toledo XS204 sold by American Instrument Exchange is inspected, cleaned, refurbished as necessary, calibrated, and tested before shipment.

Our technicians use appropriate calibration weights to evaluate critical performance characteristics including accuracy, repeatability, linearity, corner-load performance, stability, and reduced span across appropriate portions of the weighing range.

The MonoBloc weighing system, FACT automatic internal adjustment, SmartGrid, touchscreen, controls, draft shield, leveling components, interfaces, and other installed functions are inspected and tested for proper operation.

The weighing chamber, SmartGrid pan, glass panels, and accessible components are thoroughly cleaned.

The balance then receives a final operational inspection before shipment.

Each refurbished XS204 includes a 90-day warranty from American Instrument Exchange.

Shipping & Installation Considerations

Analytical balances should be carefully handled during transportation and installation.

American Instrument Exchange securely prepares the XS204 for shipment to protect its weighing system, SmartGrid pan, glass draft shield, terminal, and electronic components.

Once received, the balance should be installed on a rigid, stable, vibration-resistant weighing surface away from strong airflow, direct sunlight, doors, HVAC outlets, centrifuges, shakers, pumps, and other significant sources of vibration.

The balance should be properly leveled and allowed to acclimate to the laboratory environment before final adjustment and critical quantitative weighing.

For regulated or particularly demanding applications, installation should be followed by appropriate calibration verification, repeatability testing, minimum-weight determination, or qualification according to the laboratory's quality procedures.
