Titrators
Titrators automate the classic technique of adding a reagent to a sample until a reaction reaches its end point, delivering the precise, repeatable results that manual titration struggles to match in a busy QC lab. This category covers potentiometric titrators, Karl Fischer instruments for water content and automated systems with sample changers. Buyers can compare titration modes, electrode options and automation level, then contact sellers directly about condition and consumables. Financing on qualifying listings supports labs upgrading from manual methods.

Titrator Types
Titrators differ by the measurement principle and the parameter they determine. The variants below cover the main instrument classes.
Potentiometric titrators
Instruments that track electrode potential to detect the end point for acid-base, redox and precipitation titrations. They cover a broad range of routine QC determinations.
Karl Fischer titrators
Dedicated systems that measure water content by volumetric or coulometric Karl Fischer titration. Coulometric versions suit trace moisture while volumetric handles higher water levels.
Automated titrators with sample changers
Systems paired with a carousel or rack to process many samples unattended. They raise throughput and remove operator-to-operator variation across a batch.
Compact benchtop titrators
Space-efficient instruments for single-parameter routine titrations in smaller labs. They bring automated end point detection to a modest footprint.

Why Choose Machinery Masters
Verified Sellers Only
Every seller is verified before a single listing goes live. Machinery Masters also reviews listings for accuracy, so buyers can commit to high value machinery with confidence.
Global Reach
Listings come from sellers across Europe, North America, and beyond. That reach widens the options past any regional dealer network, and it is often the only way to find discontinued models in good condition.
Flexible Financing Options
Qualifying listings carry financing through partner providers. Terms are shown directly on eligible product pages, spreading the cost instead of draining working capital in one hit.
Direct Seller Contact
No broker sits between the buyer and the seller. Ask about service history, arrange inspections, and negotiate directly with the person who actually knows the machine.
Applications and Uses
Automated titration supports precise measurement across many QC and research settings. The examples below show where titrators are relied on.
Pharmaceutical assay and water content
Labs determine active content, acid value and moisture to confirm products meet specification. Karl Fischer titration is central to controlling water in formulations.
Food and beverage QC
Producers measure acidity, salt and other parameters to control quality and consistency. Automated titration handles the high sample counts these programmes generate.
Petrochemical and lubricant testing
Analysts determine acid and base numbers to assess product condition and quality. Potentiometric titrators provide the repeatable end points these tests need.
Environmental and water analysis
Testing labs quantify hardness, alkalinity and chloride in water samples. Automated systems keep results consistent across large sample sets.
Benefits from Machinery Masters
Within Analytical Instruments & Detection Systems, this category gathers titrators and connects you with sellers who detail electrodes, automation and consumables.
Titration platforms brought into one category
Potentiometric, Karl Fischer and automated titrators sit together for easy comparison against your parameters. That saves contacting several suppliers to cover different determinations.
Step off manual methods at a used-titrator price
A sound used titrator brings automated end point detection for a fraction of a new instrument's cost. That makes the move up from manual titration easy to justify.
Electrode and burette detail from the owner
You confirm electrode condition, burette dosing accuracy and reagent compatibility directly with the seller. Those specifics decide whether a titrator suits your methods.
Frequently Asked Questions About Titrators
The electrode and burette are the parts that most affect accuracy, so ask about their condition and age. Electrodes have a service life and may need replacement, while burette dosing units should be checked for accuracy. Confirm whether a working electrode is included. These components matter far more than the instrument's outward condition.
Confirm whether the titrator handles acid-base, redox, precipitation or Karl Fischer methods as your work requires. Some instruments cover several modes while others are dedicated. Ask whether the software supports the determinations you run. Matching modes to your methods ensures the instrument does the job.
Coulometric Karl Fischer suits trace moisture measurement, while volumetric handles samples with higher water content. Choose based on the moisture range of your samples. Confirm the reagent type the instrument uses and that it remains available. Selecting the right principle is central to accurate water determination.
Titrators use electrodes, reagents, solvents and sometimes drying agents that need regular replacement. Ask the seller which consumables the instrument requires and whether any come with it. Confirm these remain readily sourced. Understanding running costs helps you budget accurately.
Sellers are identified on the marketplace, so you can request photographs, model details and service records directly. Ask whether the titrator was removed in working order and why. Buying from the owner puts your questions about titration setup with someone who knows the unit. That transparency supports a confident purchase.
