Reagents & Standards
Reagents & Standards is the catch-all section of General Lab for prepared aqueous solutions used across routine analysis. Quality control, teaching, environmental and clinical laboratories draw on it for buffers, calibration solutions and general-purpose reagents.
The 111 Reagecon listings range from buffers such as pH 2.5 acetate buffer solution at 25°C to graded standards like acetone in water at 0.1%, 0.5% and 0.75% w/w, which suit calibration and verification of methods that measure low-level solvents. Many other prepared solutions sit alongside them, each with its concentration stated on the label.
Use the search box with the chemical name or concentration to narrow the list quickly. When a method specifies a concentration, choose the matching listing rather than diluting a stronger solution yourself, as this removes a source of error. For pH buffers used in meter calibration, see pH Buffer Solutions under Electrochemistry. Ask for a quotation on anything you need in quantity.
