Buying guides

15 selection guides, one per equipment category. Each one walks through the decisions to make before comparing models, the details a useful quotation needs, and the questions buyers ask most.

• Consumables & ReagentsOne quotation for every brand on the benchConsumables burn budget in small, frequent orders spread across suppliers. Send the whole list — catalogue numbers or specifications, any mix of brands — and it comes back as one quotation, one delivery and one tax invoice.2,223 productsRead the guide
• BalanceSpecify the smallest sample as well as the heaviest loadA balance must accommodate the container and largest load, while meeting the required accuracy for the smallest net sample. Readability is only the display increment. Start with those two loads and the allowed weighing tolerance before comparing model names or decimal places.544 productsRead the guide
• Viscometers & AccessoriesA viscosity result belongs to a complete test conditionFor comparable results, define the viscometer model or torque range, spindle, speed, temperature, container and sample preparation together. A viscosity value without those conditions may not reproduce the same test.507 productsRead the guide
• Water Testing & AnalysisTurn the water-testing requirement into a parameter-by-parameter orderA water-testing setup can combine sensors for pH, conductivity and dissolved oxygen with photometric tests for specific substances. List the result, expected range and required method for each parameter, then quote the instruments and the supplies that each method consumes.399 productsRead the guide
• pH meterChoose the meter, sensor and standards as one measurement systemFor a Thai QC laboratory or production team, a useful quotation names the meter, compatible sensor and calibration supplies together. Start with the sample and acceptance requirement, then compare range, uncertainty or accuracy specifications, and the records your method needs.388 productsRead the guide
• Electrodes & ProbesCheck the connector first, then the sampleAn electrode is chosen against two unrelated things: the meter it plugs into, and the sample it sits in. The connector decides whether it works at all. The junction and body decide how long it lasts and whether the reading can be trusted.320 productsRead the guide
• MicrobiologyBuild the equipment list from the method, not from a generic laboratory checklistISO 7218:2024 covers general requirements and guidance for food-chain microbiological examinations. The exact equipment still depends on the organism, sample, reference method and your laboratory quality system.316 productsRead the guide
• CentrifugesMatch the method, rotor and tube before comparing maximum speedA useful centrifuge quotation starts with the required separation and sample format. RCF, rotor compatibility, tube size, batch capacity and temperature control are more actionable than a model name alone.283 productsRead the guide
• Glass wareGlass type, tolerance class and joint decide the line before the brandMost glassware disputes start with a line that only says "beaker 500 mL". State the glass, the accuracy class for anything that measures a volume, and the thread or ground joint that has to fit what the lab already owns. Duran, Pyrex, Vitlab, LGS and Kartell can then be compared like for like.125 productsRead the guide
• Vacuum PumpsQuote the complete filtration path—not the pump aloneA working setup combines a pump, protection trap, tubing, filter holder, receiver and membrane that are compatible with the sample. Chemistry, viscosity, solids and batch volume determine the configuration.116 productsRead the guide
• AutoclaveStart with the load and process—not chamber litres aloneThe same chamber volume can serve very different work. Describe what will be processed, the container geometry, batch size, utilities and documentation before comparing models or asking for price.85 productsRead the guide
• IncubatorStart with the set point and the actual room temperatureA microbiological incubator, a cooled BOD incubator and a CO2 incubator are different machines, not grades of one. Fix the application, the set point and the ambient temperature of the room it will stand in before comparing chamber volumes.71 productsRead the guide
• SpectrophotometerStart with the analytical technique—not the word “spectrometer”Define the method, wavelength region, sample format and required records before comparing instruments. UV-Vis, visible, atomic absorption and chromatography are different techniques and should not be treated as interchangeable catalog names.38 productsRead the guide
• Water Purification systemChoose water quality for the application, then size the systemType I, II and III labels are a starting language—not a complete specification. Define the method’s contaminant limits, feedwater, peak and daily demand, dispense pattern and maintenance plan before comparing systems.23 productsRead the guide
• Muffle FurnaceMaximum temperature is only one part of the furnace specificationDefine the process, continuous working temperature, load, chamber, atmosphere or exhaust need, program and utilities. A furnace that reaches the setpoint may still be unsuitable for the sample or duty cycle.18 productsRead the guide
