Description

The Go Direct 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.

Experiments

Lab Ideas and Innovative Uses

  • Demonstrate the Properties of Amino Acids with a Tris-Compatible Flat pH Sensor
  • Measuring the pH of Soil with the New Tris-Compatible Flat pH Sensor

Specificiation

  • Range: pH 0–14 (Some sodium error in ranges greater than pH 12 due to thicker glass and higher impedance values)
  • Electrode type: Double-junction, sealed, gel-filled, Ag/AgCl reference, polycarbonate body
  • Membrane style: Flat glass
  • Storage solution: pH 4/KCl solution (10 g KCl in 100 mL buffer pH-4 solution)
  • Temperature range:

0– 100ºC (readings not compensated)
12 mm OD
Impedance: ~20 kΩ at 25ºC

  • Response time: 98% of full response in 30 s at 25ºC
