This is the perfect tritration unit for use in the determination of titratable acidity of milk, wine, and juice products. Ideal when portability is required. Perform accurate, precise, economical,and convenient titrations without the bulk and fragility of conventional titration equipment. Weigh your sample (18 g for milk), use pH endpoint of 8.3, then turn a dial on the titrator to accurately dispense sodium hydroxide from a cartridge. At the endpoint, read TA from the digital display. Because the titrant is not exposed to air, the concentration of the solution is maintained between titrations. Each cartridge contains a concentrated sodium hydroxide solution permitting many titrations before replacement. Suggested set up includes the digital titrator and the accessories listed below.The digital titrator comes with a plastic case and five straight delivery tubes. The J-hook delivery tubes are used when a TitraStir® continuous mixer/stand is purchased for easy dispensing.
