Balances and Moisture AnalyzersBalances & Moisture Analyzers / weighing scales measure static or dynamic loads. Features to consider when choosing an analytical balance include accuracy, capacity and resolution. Additional features and specialized balances include enclosures for weighing powder, microbalances for measuring small quantities, portable balances, moisture analyzers, top loading balances and internal calibration for measurements over time or with varied temperature.pH Meters and ElectrodesIon and pH meters are electrochemical equipment used to measure the pH (acidity or alkalinity) or specific ion concentration of a solution. Other meters can also measure the conductivity or dissolved oxygen content of a solution. pH meters, specific ion meters, conductivity meters and dissolved oxygen meters can come as benchtop or portable equipment. A meter’s electrodes can be replaced with easy to clean electrodes or electrodes for difficult media. pH, ion and conductivity meters are typically used in life science research, pharmaceutical testing, food and beverage, environmental and water analysis.

Explore a range of manual and electronic pipettes, including single and multichannel, serological and volumetric pipettes, as well as a range of pipette tips. Bottle-top dispensers are also available for simple and fast solvent dispensing. Find the best pipettes & dispensers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.TitrationTitration is an analytical technique for determining substance concentration in a solution. For titration consider a manual or automated system, volumetric or coulometric reagent addition and indication by a potentiometer, spectrometer, turbidometer or by the Karl Fischer method. Other features of titration to consider include burettes, reagents, concentration range, reaction time and autosamplers.
