Product news

HANNA’s new family of research grade laboratory benchtop instruments feature a 240 x 320 dot-matrix color display with on-screen help, simultaneous graphing, language selection and custom configuration. Four models are available to measure pH, pH and ISE, conductivity, pH, DO, BOD and conductivity.

HANNA’s pH meters feature a 5 point calibration with a choice of custom or memorized buffers and provide the user with the exclusive CAL CHECK™ electrode diagnostic system. ISE models allow direct calibration and measurement with a choice of units, as well as incremental methods.

Our new conductivity meters have EC, resistivity, TDS and salinity measuring scales. EC has an extended range from 0.001 μS/cm to 1 S/cm with auto recognition of the probe type used. Salinity measurements can be displayed in practical salinity, natural sea water or in percent scale.

All conductivity models feature stages 1, 2 and 3 USP modes plus linear and natural water temperature compensation. All models are equipped with USB and RS 232 ports for PC connectivity and offer logging, graphing and GLP.

ElectrophoresisElectrophoresis equipment is used to separate mixtures of protein, DNA or RNA, based on their electric charge, size and other physical characteristics, by passing them through a medium such as a polyacrylamide gel, an agarose gel or a capillary tube. Electrophoresis equipment includes horizontal and vertical gel electrophoresis chambers, isoelectric focusing systems, 2D electrophoresis and capillary electrophoresis instruments. Precast gels with a gradient can be used or gels can be hand cast. Samples are run alongside ladders or markers to identify the approximate size of a molecule. Separated proteins and nucleic acids in the gel can be stained or probed with fluorescent markers and then imaged and detected using gel documentation instruments, transilluminators, densitometers and scanners.

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.

Features of ph and ion meters to consider include temperature compensation, auto-calibration, adjustable resolution, measurable range and accuracy. Meters can be handheld, portable, benchtop and modular.
