30mL Dispenser.  Part of the sulfide testing kit.

250ml  Most popular of the two solutions.   Used for the determination of proteins in wine must.  It is also used to determine the quantity of bentonite needed to remove the proteins in white or rose wines.  Protein affects the turbidity of wine

Also known as boiling chips or anti bumping granules. These are used to calm the boiling to avoid overflows and for safety reason.  Use with the cash still and other applications.

Use these PTFE chips to promote gentle, efficient boiling and help prevent overheating of highly volatile liquids. Saint Gobain Performance Plastics™ Chemware™ PTFE Boiling Stones are not affected by acids, hydrocarbons, ketones, esters, alcohols or alkalis.

HI70300L is a storage solution prepared with reagent grade chemicals that can be used to ensure optimum performance of your pH and ORP electrodes. It is necessary to store a pH electrode in a solution in order to keep the glass membrane of the pH electrode hydrated. Ideally a storage solution should be used; never store an electrode in distilled or deionized water. The Hanna Instruments storage solution is specifically formulated to minimize microbial growth and to prevent any effects of diffusion/osmotic from storing a probe in a solution with the highly concentrated inner reference electrolyte. Storing your pH and/or ORP electrodes in a storage solution will also keep the junction clear. Maintaining the hydrated layer and clear junction will help to ensure a fast and reliable measurement. In the case of cleaning your pH electrode in one of our cleaning solutions, we recommend soaking the electrode in the HI70300L storage solution for at least one hour before taking measurements.

• Special formulation to minimize microbial growth and osmotic/diffusion effects between the solution and inner reference electrolyte
• Manufactured specifically for pH and ORP electrodes
• Clearly marked expiration date and lot number

HI7082 is a pH and ORP electrode fill solution that contains 3.5M KCl, which is specifically produced for double junction electrodes. The electrolyte level in refillable electrodes should be checked before performing any measurements. If the level is low, refill with the proper electrolyte solution to ensure optimum performance. This simple maintenance helps guarantee adequate head pressure to promote the flow of reference electrolyte into the sample being measured.

• Fill solution for double junction pH & ORP electrodes
• Convenient 30 mL bottles
• Clearly marked bottle with expiration date and lot number

The HI70635L is a highly effective cleaning solution that is specially formulated for use with pH electrodes that become coated with wine juice and must deposits. Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. Hanna’s cleaning solutions eliminate impurities and residues that are left on electrode surfaces when immersed in samples during measurement and stored incorrectly. Hanna suggests cleaning the bulb and junction of your electrode on a regular basis to ensure that the probe is always clean and prevent any clogging of the junction. Measuring the pH in wine is a critical step ensuring the quality of the final product, for more information read our ebook.

Hanna’s line of cleaning solutions have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened bottle.

• Specially formulated cleaning solution to remove wine deposits from a pH electrode
• Air tight bottle with tamper-proof seal to ensure quality
• Expiration date and lot number clearly marked on the bottle

The HI84102 is an automatic mini titrator for titratable acidity in wine. The HI84102-50 is the titrant solution to be used with the HI84102. The titrant is pre-standardized eliminating the need for any volumetric glassware or a analytical balance. The HI84102 with the prepared HI84102-50 makes titratable acidity titrations 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
