Mettler Toledo analytical instruments
We personally find you the right new, used and refurbished mettler toledo analytical instruments from verified suppliers.
Mettler Toledo analytical instruments on Questpair are built around weighing: the XPR Excellence analytical and micro balances, the XSR Excellence precision balances, and a range of laboratory scales that read to the microgram. Among the listings that specify a type, analytical balances and precision balances dominate, alongside laboratory scales and electronic balances. The catalogue holds 1239 items from 19 verified suppliers and distributors across 10 countries. These are the instruments that sit under the first weighing step of a titration, a moisture determination, or a dilution series, so their readability and settling behaviour set the error floor for the analyses downstream.

Choosing a Mettler Toledo analytical instrument
Start with the smallest sample you weigh, not the heaviest. On a Mettler Toledo balance the deciding specification is minimum weight, the point below which measurement uncertainty exceeds the tolerance you can accept. An XPR analytical model holds a lower minimum weight than an XSR precision model, so a lab dosing micrograms needs the analytical tier regardless of how much bench space a larger-capacity balance would save. Weigh your routine sample mass against each line's readability before price enters the decision.
On a used unit, three things wear or drift. The internal calibration weight and its motorised mechanism age; ask the seller for a recent calibration record or an as-found report, since a balance without one is a reading you cannot defend. The levelling feet and the integrated level sensor matter because an analytical balance out of level reads false; confirm the feet turn freely and the bubble or electronic level responds. The draft shield glass and its runners take knocks in transit, so check that doors close square and seal.
The price band breaks along generation and tier. The cheapest listings are compact scales and spare parts; the middle holds older XSR and prior-generation analytical balances that still meet their original specification; the top is current XPR hardware with LabX connectivity. A ten-year-old analytical balance that has been serviced can outperform a neglected newer one, so condition outranks model year within a tier.
Watch the compatibility traps between Mettler Toledo's own components. A weighing pan and draft shield are specific to a balance family; an XPR accessory will not seat on an XSR. LabX software licences are tied to instrument generation, so confirm the unit's firmware supports the software version you intend to run before counting on a data trail. Where a listing omits the calibration history, parts can be sourced via Questpair to bring a sound balance back to specification.
Mettler Toledo balance series in the lab
Among the listings that specify a type, this pair holds analytical balances, precision balances, laboratory scales and electronic balances. The XPR Excellence line covers the analytical and microbalance end: readabilities down to the microgram, draft shields, and the SmartGrid weighing pan that reduces air turbulence around the sample. It suits a lab weighing reference standards, catalysts, or anything dosed below a milligram. The XSR Excellence line is the precision tier, reading to the milligram or hundredth of a gram over a larger capacity, which fits buffer preparation, bulk reagent weighing and routine QC. Below the Excellence families sit the EasyPlus and compact balances, aimed at teaching labs and benches where a readable milligram is enough. The series come from Mettler Toledo's own range; the intersection with this category is almost entirely the weighing instruments rather than the titrators or meters the maker also builds.
Where the XPR and XSR diverge
The dividing specification is readability against capacity, and the two lines are built for opposite ends of it. An XPR analytical balance typically reads to 0.01 mg or 0.1 mg with a capacity measured in low hundreds of grams, and its settling time and repeatability are what justify the price for sub-milligram work. An XPR microbalance pushes readability to the microgram and caps capacity far lower still. An XSR precision balance trades that resolution for range, reading to the milligram or centigram while carrying several kilograms. For reference-standard weighing the analytical model is the only honest choice; for preparing litres of buffer the precision model weighs faster and tolerates a heavier vessel. Minimum weight, not maximum capacity, is the figure that decides whether a given balance can legally report a given sample, so match the smallest sample you weigh to the balance, not the largest.
What a used Mettler Toledo balance costs here
Prices run from EUR 30 to EUR 40.046. The low end covers accessories, spare pans and simple electronic scales; the high end is a current-generation XPR analytical or microbalance with a draft shield and software. The average listing sits at EUR 1.592. 98 percent of the listings are used. That condition mix means most of what is on offer has a service history behind it, which matters more for a balance than for most instruments: the load cell, the levelling feet and the calibration record are what a buyer is really paying for.
Frequently asked questions
Which analytical instrument series does Mettler Toledo make?
The weighing lines are the XPR Excellence for analytical balances and microbalances, the XSR Excellence for precision balances, and the EasyPlus range for compact titrators, pH meters and density meters. On the chemistry side there are SevenExcellence meters for electrochemistry and the Titration Excellence T5, T7 and T9 instruments, often paired with InMotion autosamplers.
How do the XPR, XSR and EasyPlus series differ?
XPR analytical balances and microbalances resolve down to 0.1 mg or 1 microgram over a modest capacity of a few hundred grams, while XSR precision balances offer milligram readability across capacities that can reach several kilograms. EasyPlus covers the compact end, where a titrator, pH meter or density meter performs a fixed function rather than a configurable platform.
How much does a used Mettler Toledo analytical instrument cost?
Across the Questpair catalogue prices run from EUR 30 to EUR 40.046, with the average listing at EUR 1.592. The lower figures cover second-hand scales, accessories and spares, while the upper end covers automated titration systems and multi-station analytical setups.
Are refurbished Mettler Toledo units available?
Yes, both used and refurbished units appear in the catalogue, and 98 percent of the listings are used. Refurbished and used units are listed at lower prices than new equipment.
Which model suits which application?
Choose an XPR analytical or microbalance for sample weighing, filter analysis and formulation where sub-milligram resolution decides the work, and an XSR precision balance for bulk formulation and larger sample preparation where range matters more than the last decimal place. For chemistry, a single-method T5 titrator suits manual work while a T9 with an InMotion autosampler runs sequences unattended, and SevenExcellence meters cover pH, conductivity and ion-selective measurement depending on channel count.
What should I check before buying a used Mettler Toledo balance?
Ask the seller for a recent calibration record and, for an analytical balance or microbalance, confirm that internal adjustment weights are present and functioning. Check that the draught shield is intact and the doors run cleanly, since a warped shield undermines the resolution the instrument is bought for, and for titrators and pH meters confirm whether electrodes and burettes are included or exhausted.
Are parts and accessories interchangeable across the series?
InMotion autosamplers pair with specific titrator models rather than universally, so confirm the pairing before buying, and LabX software licences are separate from the hardware with the tier varying by unit. Parts can be sourced via Questpair when a listing does not include what you need.
How does Mettler Toledo compare to other analytical balance brands?
Within this maker's range the deciding distinction is readability against capacity, which separates the XPR, XSR and EasyPlus lines rather than ranking one above another. The Questpair catalogue holds 1239 of these instruments from 19 verified suppliers and distributors across 10 countries, so comparison here is mainly about condition and calibration state across the available listings.
