pH Storage Solution

Use the Tris-Compatible Flat pH Sensor to measure the pH of a solution or semisolid, such as food or soil. The Tris-Compatible Flat pH Sensor is a highly versatile sensor. Because the glass membrane is flat instead of a bulb, it is more durable, easier to clean, and allows for flat surface measurements or smaller sample sizes. It features a sealed, gel-filled, double-junction electrode, making it compatible with Tris buffers and solutions containing proteins or sulfides. The flat glass shape also makes it useful for measuring the pH of semisolids such as food or soil slurries. Range:pH 0–14 User manual

The Go Direct Electrode Amplifier offers an affordable way to expand your experiment options. Its BNC connector provides the flexibility to attach and remove a Vernier electrode, such as the pH Electrode, Flat pH Electrode, ORP Electrode, ISE electrode, or a third-party electrode. You can explore pH one day and potassium concentrations the next.   Because the Go Direct Electrode Amplifier is compatible with third-party electrodes, students learn consistent calibration and handling techniques on one amplifier using one software program. When electrodes expire or become damaged you need only replace the electrode—lowering your overall equipment costs.   Rechargeable Battery—Ready When You Are The robust rechargeable battery offers long battery life and provides always-ready operation when using the sensor wirelessly. Monitor battery life directly from our free Graphical Analysis™ 4 app or LabQuest 2 App. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students.   Wired or Wireless—The Flexibility to Choose Our Go Direct sensors connect directly to your mobile device, Chromebook™, or computer using our free Graphical Analysis™ 4 app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth® wireless technology, allowing you to choose the solution best for your classroom or laboratory.

Utilizzate il sensore di pH proprio come fareste con un pHmetro tradizionale, con i vantaggi aggiuntivi della raccolta automatica dei dati, della creazione di grafici e dell'analisi dei dati. Le attività tipiche che utilizzano il nostro sensore di pH includono: Titolazioni acido-base Studi sugli acidi e le basi per uso domestico Monitoraggio delle variazioni di pH durante reazioni chimiche o in acquario come risultato della fotosintesi Indagini sulle piogge acide e sui tamponi Analisi della qualità delle acque di torrenti e laghi Se state studiando tamponi Tris o semisolidi di questo tipo, prendete in considerazione il sensore di pH piatto Vernier Tris-Compatible.

The Oxidation-Reduction Potential (ORP) Sensor measures the ability of a solution to act as an oxidizing or reducing agent. Use the ORP Sensor to measure the oxidizing ability of chlorine in swimming pools or to determine when the equivalence point has been reached in an oxidation-reduction reaction. Type:Sealed, gel-filled, epoxy body, Ag/AgCl reference Storage solution:pH-4/KCl solution (10 g KCl in 100 mL buffer pH-4 solution) Redox potential range:-450 to +1100 mV User manual

The Go Direct pH Sensor is a general-purpose pH sensor used to monitor pH of aqueous solutions. It directly connects wirelessly via Bluetooth® or wired via USB to your platform. The Go Direct pH Sensor is an important and versatile sensor for lab and field activities alike. It gives students the freedom to explore pH without the inconvenience of wires—no more spilled solutions or dangling wires. The Go Direct pH transmits live readings and captures data in real-time. The Go Direct pH Sensor can be used in a variety of experiments: Conduct acid-base titrations. Monitor pH change during chemical reactions. Test the pH and alkalinity of bodies of water. Investigate household acids and bases. This sensor is comprised of a pH electrode connected to a Go Direct Electrode Amplifier via a BNC connector. This design enables you to use the Go Direct Electrode Amplifier with other Vernier electrodes, such as the Flat pH Electrode, ORP Electrode, ISE electrode, or a third-party electrode.

Der Go Direct Tris-kompatible pH-Sensor mit flacher Elektrode ist ein äußerst vielseitiger Sensor. Da die Glasmembran anstelle einer Kugel flach ist, ist sie haltbarer, leichter zu reinigen und ermöglicht flache Oberflächenmessungen oder kleinere Probengrößen. Er verfügt über eine versiegelte, gelgefüllte Doppelkontaktelektrode, die es kompatibel mit Tris-Puffern und Lösungen mit Proteinen oder Sulfiden macht. Die flache Glasform ermöglicht die Messung des pH-Wertes von pastosen und halbfesten  Stoffen wie Lebensmittel oder Bodenschlämmen.
