The Mettler Toledo XS64 is a traditional 0.1 mg analytical balance optimized for relatively small samples.
Its 61 g maximum capacity is considerably lower than the 120 g, 220 g, or higher capacities offered by many other analytical balances, but that is not necessarily a disadvantage.
For laboratories primarily weighing small quantities of chemicals, pharmaceutical ingredients, reference standards, filters, powders, or research samples, the additional capacity of a larger analytical balance may simply be unnecessary.
The XS64 instead provides a compact analytical weighing system with the same 0.1 mg resolution expected from larger analytical balances.
Its Excellence XS platform adds automatic internal adjustment, SmartGrid technology, motorized draft-shield operation, touchscreen controls, electronic connectivity, and integrated weighing applications.
This combination makes the XS64 particularly attractive for laboratories that want a sophisticated analytical balance without paying for weighing capacity their applications do not require.
The Mettler Toledo XS64 is well suited for analytical chemistry, pharmaceutical research, reference-standard preparation, quantitative sample preparation, gravimetric analysis, reagent weighing, filter weighing, residue determination, quality control, density determination, formulation research, and other small-sample analytical procedures.
Pharmaceutical and biotechnology laboratories can use the XS64 for active ingredients, standards, research compounds, formulation components, and other relatively small samples.
Chemical laboratories can use the balance for quantitative analysis, compound preparation, solution preparation, and gravimetric procedures.
Environmental laboratories may use the XS64 for filters, residues, and other applications where the total load remains within its 61 g capacity.
Academic, materials science, cosmetics, food science, and industrial research laboratories can also use the XS64 wherever conventional 0.1 mg analytical resolution is required.
The XS64 is particularly well suited for pharmaceutical, biotechnology, chemical, environmental, academic, materials science, analytical testing, quality-control, and research laboratories.
It is an especially logical choice for laboratories whose samples and weighing vessels consistently remain well below 61 g.
A laboratory weighing milligram- or gram-scale chemical samples may gain little practical benefit from purchasing a 220 g analytical balance if its procedures never approach that capacity.
In those environments, the XS64 provides full analytical resolution in a compact, sophisticated weighing platform.
Laboratories that regularly use heavier bottles, vessels, filters, containers, or tare weights should instead consider a higher-capacity analytical balance.
The XS64 provides 0.1 mg / 0.0001 g readability throughout its weighing range.
Mettler Toledo's technical specifications identify a 0.1 mg repeatability limit at a 60 g load and approximately 0.07 mg at a 10 g load.
Under reference conditions, typical repeatability can be approximately 0.04 mg.
This distinction is useful when evaluating balance performance.
The 0.1 mg figure represents the manufacturer's specified repeatability limit at a high load, while the lower typical value represents performance that may be achievable under favorable operating conditions.
Mettler Toledo specifies 0.2 mg linearity deviation and an approximately 1.5-second stabilization time.
Together, these specifications make the XS64 well suited for routine analytical weighing where fast stabilization and consistent sub-milligram performance are required.
Minimum sample weight should not be confused with the XS64's 0.1 mg readability.
Readability simply describes the smallest increment shown on the balance display.
Minimum sample weight depends primarily on repeatability and the maximum relative measurement uncertainty permitted by the procedure.
This distinction becomes especially important in pharmaceutical, quality-control, and regulated laboratory environments.
For USP applications, laboratories should establish minimum sample weight from the actual repeatability of the installed XS64 under its operating conditions rather than assuming that the smallest displayed increment represents an acceptable quantitative sample.
Environmental stability, calibration condition, weighing technique, vibration, static electricity, and sample characteristics can all affect installed performance.
This is why repeatability testing is an important component of both balance qualification and American Instrument Exchange's refurbishment process.
At 0.1 mg readability, air movement can significantly influence weighing stability.
The XS64 incorporates a fully enclosed analytical draft shield to isolate the SmartGrid weighing pan from surrounding laboratory airflow.
Motorized draft-shield operation also allows users to access the weighing chamber without repeatedly moving glass panels by hand.
This can reduce physical interaction with the balance and improve workflow during repetitive weighing.
The draft shield does not eliminate the need for proper balance placement.
The XS64 should still be installed away from HVAC outlets, open windows, frequently used doors, fans, and other significant airflow sources.
The XS64 incorporates Mettler Toledo's SmartGrid weighing pan, which is specifically designed to reduce the influence of air turbulence inside the weighing chamber.
Rather than presenting a large solid surface to moving air, the grid-style pan reduces the surface area exposed to airflow.
This can help the balance reach a stable measurement more quickly after the draft shield is opened and a sample is introduced.
SmartGrid is particularly useful during repetitive analytical procedures where samples are frequently exchanged.
The design also allows spilled material to fall below the primary weighing surface, helping make the weighing chamber easier to inspect and clean.
The XS64 incorporates FACT automatic internal adjustment.
FACT allows the balance to perform automatic adjustment using its internal reference system when defined conditions indicate that adjustment is necessary.
This helps maintain weighing performance without requiring the operator to manually place an external calibration weight on the SmartGrid pan every time routine adjustment is required.
For an analytical balance capable of resolving 0.1 mg changes, this can be particularly useful as laboratory temperature conditions change throughout the day.
FACT does not eliminate the need for independent verification.
Laboratories operating under USP, GMP, GLP, ISO, or internal quality procedures may still require scheduled performance checks using appropriate traceable external reference weights.
American Instrument Exchange verifies operation of the internal adjustment system and externally evaluates weighing performance during refurbishment.
One of the more useful features of the XS64 is its motorized draft-shield system.
Reducing the need to manually move draft-shield panels can improve efficiency during repetitive analytical weighing.
It can also reduce the amount of physical contact with the balance and minimize unnecessary disturbances inside the weighing chamber.
The Excellence XS draft shield is designed to be dismantled without specialized tools, simplifying routine cleaning of the glass panels and weighing chamber.
For laboratories processing many analytical samples each day, these ergonomic features can make a meaningful difference in workflow.
Analytical balances should be installed on a rigid, stable, level weighing surface away from significant vibration.
Centrifuges, shakers, pumps, compressors, refrigerators, freezers, and other laboratory equipment can transmit vibration through benches, floors, and building structures.
Temperature stability is also important.
Samples that are substantially warmer or cooler than the surrounding laboratory can create convection currents inside the weighing chamber and contribute to unstable results.
Static electricity may affect powders, filters, plastic vessels, glassware, films, and other materials prone to accumulating charge.
When necessary, appropriate antistatic devices, conductive containers, grounding procedures, or humidity control can help reduce electrostatic influences.
The XS64 uses Mettler Toledo's Excellence touchscreen interface, providing convenient access to weighing functions, balance settings, applications, and stored information.
Integrated applications allow the XS64 to support more than basic mass determination.
Depending on configuration, the platform can support procedures including statistics, formulation, density determination, percentage weighing, piece counting, differential weighing, and other laboratory workflows.
These functions can reduce manual calculations and simplify repetitive procedures.
For multi-step laboratory workflows, stored settings can also help improve consistency between measurements.
The XS64 supports electronic connectivity for integration with compatible computers, printers, peripherals, and laboratory data systems.
Electronic transfer of weighing results can reduce manual transcription and the risk of recording errors.
The Excellence XS platform is also compatible with Mettler Toledo LabX.
When appropriately configured, LabX can support electronic result capture, calculations, data storage, traceability, and standardized weighing workflows.
For laboratories moving away from handwritten weighing records, these capabilities can extend the useful life of the XS64 beyond simple standalone weighing.

The XS64 provides the same 0.1 mg readability commonly found on 120 g and 220 g analytical balances, but with a significantly lower maximum capacity.
Whether this matters depends entirely on the application.
For laboratories routinely weighing samples of only a few milligrams or grams in lightweight vessels, a 61 g capacity may provide ample working range.
There is little benefit to purchasing substantially more capacity if it will never be used.
A 220 g analytical balance becomes preferable when laboratories regularly work with heavier tare vessels, larger samples, bottles, containers, or procedures where total loads may exceed 61 g.
The XS64 is therefore particularly attractive as a small-sample analytical balance, while higher-capacity models offer greater flexibility for diverse sample sizes.
The XS64 and XS204 are closely related Excellence analytical balances that provide the same 0.1 mg readability.
Their primary difference is capacity.
The XS64 provides 61 g maximum capacity, while the XS204 provides 220 g maximum capacity.
The XS204 is therefore substantially more flexible when laboratories work with heavier samples or tare vessels.
The XS64 can be an excellent choice when samples consistently remain below 61 g and additional capacity is unnecessary.
Because both models provide the same displayed resolution, choosing between them is primarily a question of required working capacity rather than readability.
The XS64 and XS105 serve different analytical requirements.
The XS64 provides 61 g capacity with 0.1 mg readability.
The XS105 provides 120 g capacity with much finer 0.01 mg / 10 µg readability.
The XS105 therefore offers both greater capacity and ten times finer displayed resolution, but that additional sensitivity also increases environmental requirements and is unnecessary for many routine analytical procedures.
The XS64 is appropriate when conventional 0.1 mg analytical resolution satisfies the method.
The XS105 becomes preferable when the application genuinely requires semi-micro-level sensitivity.
It can be tempting to select the laboratory balance with the greatest possible resolution, but additional sensitivity does not automatically produce better laboratory results.
Higher-resolution balances are generally more susceptible to airflow, vibration, temperature gradients, static electricity, and operator technique.
For many quantitative chemistry, standards preparation, reagent weighing, quality-control, and research procedures, 0.1 mg analytical readability provides an appropriate balance between sensitivity, stability, speed, and ease of use.
The XS64 is particularly well suited to these applications when total sample and tare weight remains within its 61 g capacity.
Every used Mettler Toledo XS64 sold by American Instrument Exchange is inspected, cleaned, refurbished as necessary, calibrated, and tested before shipment.

The MonoBloc weighing system, FACT automatic internal adjustment, SmartGrid pan, motorized draft shield, touchscreen, controls, leveling components, interfaces, and other installed functions are inspected and tested for proper operation.
The weighing chamber, SmartGrid pan, draft-shield panels, and accessible surfaces are thoroughly cleaned before the balance receives a final operational inspection.
Each refurbished XS64 includes a 90-day warranty from American Instrument Exchange.
American Instrument Exchange securely prepares the XS64 for shipment to protect its sensitive weighing system, SmartGrid pan, motorized draft shield, touchscreen terminal, glass panels, and electronic components.
After delivery, the balance should be installed on a rigid, stable, vibration-resistant weighing surface away from HVAC outlets, direct sunlight, doors, centrifuges, shakers, pumps, compressors, and other significant sources of airflow or vibration.
The XS64 should be properly leveled and allowed to acclimate to the laboratory environment before final adjustment and critical quantitative measurements are performed.
For regulated applications, installation should also be followed by appropriate calibration verification, repeatability testing, minimum-weight determination, or qualification according to the laboratory's quality procedures.
American Instrument Exchange maintains an extensive inventory of used and refurbished laboratory balances, including analytical balances, semi-micro balances, microbalances, and precision balances for applications ranging from routine sample preparation to high-resolution quantitative analysis.
