A free molarity and dilution calculator covering four essential lab calculations: C1V1=C2V2 dilution (solve for any unknown), molarity from mass, mass from molarity, and serial dilution table generation. Includes worked examples, a concentration units guide and step-by-step preparation instructions for every result.
Free online buffer preparation calculator. Select your buffer system, enter target pH, concentration and volume, and get an exact lab-ready recipe with reagent masses and step-by-step instructions. Covers PBS, Tris-HCl, sodium phosphate, acetate, HEPES, MOPS and more.
Laboratory balances are essential weighing instruments used to measure samples, reagents, powders, chemicals and materials with accuracy and consistency. They are commonly used in research, education, quality control, pharmaceutical testing, food testing, industrial laboratories and general scientific workflows.
pH meters are essential laboratory instruments used to measure how acidic or alkaline a liquid sample is. They are widely used in research, water testing, food and beverage analysis, education, environmental monitoring, quality control and manufacturing where accurate and repeatable pH measurement is required.
Magnetic stirrers and hot plate stirrers are essential laboratory instruments used for consistent mixing, solution preparation and controlled heating. They are commonly used with beakers, flasks and bottles to dissolve solids, prepare reagents, maintain suspensions and support routine sample preparation across research, education, quality control and industrial laboratories.
