However, in the context of luminal and perivascular compartments, the application of a pH gradient is limited not only by the presence of the local neutral environment , but also by the fact that mildly acidic microenvironment is so far away from the tumor blood vessel networks (i.e., 100200 m) to exert an effective pH gradient [56,57].

Cleaning Agents and Surface Treatments Selection Guide

pH, or potential of Hydrogen, is a measure of the acidity or alkalinity of the substance, ranging between 0 and 14. pH plays a role in the function and cleaning power of acid (low pH) or alkaline (high pH) solutions. However, solutions with very high or very low pH are also much more hazardous to both equipment and personnel.

Some substances are classified as either an acid or a base. Think of acids and bases as oppositesacids have a low pH and bases have a high pH. For reference, water (a neutral) has a pH of 7 on a scale of 014. Scientists can tell if a substance is an acid or a base by means of an indicator. An indicator is typically a chemical that changes
