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.
