This lab includes a theoretical explanation of how buffers work and how they are made, including a derivation of the Henderson-Hasselbalch equation. Students will use what they have learned to ...

This lab includes a demonstration of the proper use of a burette system for titrations; including a detailed description, instructional video, and opportunity for students to collect data to ...

pH meters are used to determine the pH of a water sample or solution. There are four pH meters in the engineering laboratories. pH meters use electrodes to determine the difference in electrical ...

In this presentation, we will present a novel way of concentrating samples and performing buffer exchange using the µPULSE —TFF System. The instrument is a fully automated walk-away system that uses ...

Salmo gairdneri erythrocytes were lysed and the oxygen-binding properties of the haemolysates in 0.1 M tris-HCl, veronal-HCl, imidazole-HCl and phosphate buffers were determined over the pH range ...
