pH and ORP Solutions

Ready-made Solutions Buffer solutions that can be prepared in small batches from capsules, tablets or powders, are called “fresh” because they are prepared at the time of use. They are considered to be, but are not very precise. The quality of buffer solutions produced depends onmany factors including the quantity and quality of the chemicals and distilled water used in production. Other important factors are the temperature and the instruments used to prepare them. Hannabuffersolutionsarecheckedcarefully, inanasepticenvironment with the highest precision reference instruments, and are calibrated to NIST Standards. Hanna solutions are more convenient than the so-called “fresh” solutions. The main standard buffer solutions produced by Hanna are available in bottles or in sealed sachets, complete with or without a certificate of analysis. The following pages show the series of calibration solutions in the various types of packages that will satisfy every application need, while always guaranteeing a highly accurate buffer. A Complete Range The entire range of Hanna solutions include: · · pH buffer solutions · · Standard solutions for conductivity, TDS, turbidity, salinity and ISE calibration · · ORP test and pretreatment solutions · · Reference fill solutions for refillable electrodes · · General and specific cleaning solutions for electrodes · · Solutions for electrode maintenance and storage · · Solutions for sample preparation Solutions are available inmany sizes ranging from20mL sachets to 3.78 L (1 gallon) containers for large quantities used in laboratories. For safety and traceability, all Hanna solutions are provided with a label showing the batch number and expiration date. Calibration and Cleaning Solutions The fundamental use of calibration and cleaning solutions is to correctly maintain electrode operation to assure accurate and reproducible readings. Often, readings are not correct because the sensors have not been properly handled. Using Hanna’s wide range of solutions will help guarantee proper cleaning and calibration of electrodes and probes for maximum performance. Our application-engineered solutions have been produced with reference instruments calibrated with NIST standards. Our range of buffer and cleaning solutions have been extended with three new lines: the HI50XX series of technical buffer solutions allows for calibration of pH meters from 1.00 to 13.00 pH; the HI60XX series of solutions with millesimal resolutions is available for pHmeasurements with an accuracy of ±0.002 pH; finally, the HI70XX application specific cleaning solutions available in bottles of 250 and 500 mL, as well as in small sachets of 20 mL each.

A Wide Variety of Single Dose Sachets

Get the best out of your instruments using single dose Hanna calibration and maintenance solutions. A wide range of pH, conductivity, TDS and cleaning solutions are available in the form of practical 20 mL sachets. Sachets are Practical, Safe and Ready to Use Single dose sachets are quick and easy to use. Each sealed, light-tight sachet holds just the right amount of solution. Every time your instrument is calibrated using these Hanna sachets, it is like using a newly opened bottle of solution.

Combination Kits in Bottles and Sachets These kits are useful for multiparameter instruments or for two-point calibration. Table of Reference Temperatures

All calibration solutions are provided with a label presenting a reference table of the relationship between pH or conductivity values and temperature. Bottles that Meet FDA Standards For accuracy over an extended period of time, ask for Hanna solutions in FDA (US Food & Drug Administration) type light-tight bottles. Certified Solutions For those operators who request it, we provide standard solutions complete with certificate of analysis. These certificates are prepared in accordance with NIST standards to avoid any possible error in determining the actual pH value. HI50XX and HI60XX series solutions are provided with a certificate of analysis. HI70XX series certified solutions are provided with certificate/box. Solutions in sachets (HI700xxC series) are also available with a certificate of analysis. Just like in our bottled solutions, the certificate shows the date of production, batch number and expiration date.
