The HI84502-50 is a 230 mL bottle of titrant solution for use with the HI84502 TItratable Acidity Mini Titrator for Wine Analysis. The HI84502-50 titrant solution is used for both the low and high acidity ranges. The titrant is pre-standardized, eliminating the need for any volumetric glassware or a analytical balance and ensuring titrations are fast, accurate, and simple to perform. Pre-standardized titrant Clearly marked expiration date and lot number Air tight bottle with tamper-proof seal to ensure quality The HI84502-50 is a 230 mL bottle of alkaline titrant solution that is used for low and high range determinations of acidity in wine. The HI84502 mini titrator is designed to determine the acidity of wine by potentiometric titration in both a low range (0.1 to 5.0 g/L of tartaric acid) and high range (4.0 to 25.0 g/L of tartaric acid). Total acidity for both ranges is measured on a degassed sample of wine to a fixed endpoint of pH 8.20. The determination of total acids in wine is made according to a neutralization reaction, that is the reaction between the acids found in wine and a base. Total acidity, also referred to as titratable acidity, is the sum of the fixed and volatile acids. In the United States, the total acidity of wine is usually expressed in terms of tartaric acid, even though the other acids are measured. Total acidity directly affects the color and flavor of wine and, depending on the style of the wine, is sought in a perfect balance with the sweet and bitter sensations of other components. Too much acidity makes wine tart and sharp; too little makes wines flat and uninteresting. Proper acidity in wine is what makes it refreshing and an ideal accompaniment to food. Replacement reagents required to operate the HI84502 include:   Low Range - 0.1 to 5.0 g/L of tartaric acid High Range - 4.0 to 25.0 g/L of tartaric acid Pump calibration standard HI84502-55 Titrant solution HI84502-50

The HI84502-55 is a 120 mL bottle of pump calibration standard that is used to calibrate the dosing system of the HI84502 TItratable Acidity Mini Titrator for Wine Analysis. With 4 mL of solution required per pump calibration, there is enough standard to perform approximately 30 pump calibrations. A calibrated dosing pump allows for the accurate determination of the amount of titrant used when performing a titration. The amount of volume dosed along with the concentration of the titrant is used by the pre-programmed formula within the HI84502 in determining the exact titratable acidity. The pump calibration procedure should be performed anytime the titrant or pH electrode is replaced. Routine calibration is recommended to ensure the highest of accuracy when performing a titration. Pre-measured solution Clearly marked expiration date and lot number Air tight bottle with tamper-proof seal to ensure quality Analysis of titratable acidity in wine, as performed on the HI84502 mini titrator, utilizes a simple sample preparation, a high-quality titrant dosing pump, potentiometric endpoint detector, and automatic computations. As the titrant comes pre-standardized, it is important to determine the amount of titrant delivered by the dosing pump by performing a pump calibration procedure. In this procedure, the analysis of a known volume of a known solution is titrated with to the pH 8.2 endpoint determined by the HI1048B pH electrode. The same pump calibration solution is used for both the low and high ranges. The pump calibration procedure should be performed anytime the titrant, syringe, tubing or pH electrode is replaced. It is recommended to do a pump calibration every time a new set of titrations are to be performed.   Replacement reagents required to operate the HI84502 include:   Low Range - 0.1 to 5.0 g/L of tartaric acid High Range - 4.0 to 25.0 g/L of tartaric acid Pump calibration standard HI84502-55 Titrant solution HI84502-50 Used to calibrate the dosing system of the HI84502 TA Mini Titrator for Wine Analysis with one bottle allowing for appx 30 (4mL) pump calibrations Clearly marked expiration date and lot number, Air tight bottle with tamper-proof seal to ensure quality.

The HI1048B is a glass body, refillable, sleeve junction pH electrode with a BNC connector. This electrode features a double junction reference, Hanna's Clogging Prevention System (CPS) technology and spherical glass sensing bulb made with general purpose glass. This pH electrode is ideal for wine must and juice due to their high solids content that would clog a standard general purpose pH electrode. Clogging Prevention System (CPS™) Technology Refillable Electrode Double Junction Design Hanna Instruments offers a wide variety of pH electrodes that are designed for many different applications. The type of glass used for sensing pH, bulb shape, body material, type of junction, type of reference and electrolyte used are just some of the design considerations.   The HI1048B uses general purpose (GP) glass, spherical bulb, glass body, sleeve junction with CPS™ technology, double junction and is refillable with 3.5M KCl, making it ideal for wine must, juice, and other samples with a high solids content.   General Purpose Glass Formulation General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring the pH of samples that are at ambient temperatures. The HI1048B is suitable to use with samples that measure from 0 to 80°C.   Spherical Glass Tip The spherical shaped tip design allows for a wide area of contact with the measured sample. This permits a faster electrode response with a higher degree of stability.   CPS Sleeve Junction Clogging Prevention System (CPS) technology is an innovation in for the improvement of pH measurements in samples that have a high solids content. Conventional pH electrodes use ceramic junctions that can clog quickly when used in samples that have a high solids content such as wine must or juice. When the junction is clogged, the electrode does not function. CPS technology utilizes the porousness of ground glass coupled with a PTFE sleeve to prevent clogging of the junction. The ground glass allows the proper flow of the liquid, while the PTFE sleeve repels solids. As a result, pH electrodes with CPS technology take up to 20 times longer to be fouled as compared to conventional electrodes.   Double Junction Reference A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or for samples that contain sulfides that can cause the silver to precipitates and clog the junction. The clogging of the junction will result in drifty and erratic readings.   Refillable The HI1048B is a refillable probe. Since it is a double junction pH electrode, the fill solution is the HI7082 3.5M KCl. This solution does not contain any silver as with single junction electrode fill solutions.   Glass Electrode Body The glass body is ideal for laboratory use. The glass is resistant to many harsh chemicals and is easily cleaned. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent. The faster the equilibrium the steadier the reference potential.   BNC Connector The HI1048B has a BNC connector. This type of connector is universal in that it can be used on any pH meter that has a female BNC probe input. Other types of connectors include DIN, screw type, T-type, and 3.5mm to name a few. These types of connectors tend to be proprietary for a particular type of meter and are not interchangeable.   Single Junction Versus Double Junction pH Electrodes Conventional electrodes are normally single junction. As depicted by the figure above, these electrodes have only a single junction between the internal reference wire and the external solution. Under adverse conditions, such as high pressure, high temperature, highly acidic or alkaline solutions, the positive flow of the electrolyte through the junction is often reversed resulting in the ingress of sample solution into the reference compartment. If this is left unchecked, the reference electrode can become contaminated, leading to complete electrode failure. Another potential problem with single junction electrodes is the clogging of the junction due to silver chloride (AgCl) precipitation. Silver can be easily precipitate in samples that contain Tris buffer or heavy metals. When the electrolyte solution makes contact with the sample, some AgCl will precipitate on the external face of the junction. The result is drifty readings obtained from the sensor.   Hanna’s double junction system, as the name implies, has two junctions, only one of which is in contact with the sample as shown in the figure. Under adverse conditions, the same tendency of sample ingress is evident. However, as the reference electrode system is separated physically from the intermediate electrolyte area, the contamination of the electrode is minimized. The likelihood of clogging of the junction is also reduced with a double junction electrode since the outer reference cell uses a fill solution that is “silver-free”. Since there is no silver present, there is no precipitate forming to clog the junction.
