Have you ever wondered why your titration results are not reproducible? This blog post discusses the most common random and systematic errors that can happen during a titration. It should serve as a guide to help identify and minimize the sources of these errors in titration ...

Have you ever asked yourself why you need an electrode for the endpoint detection in Karl Fischer (KF) titration? Theoretically, the endpoint of a Karl Fischer titration could be determined based on the color change of the reagent. However, if accuracy and reproducibility are important, endpoint detection with a double Pt electrode is a much better choice. As the indicator electrode ...
Using a manual buret filled with titrant, I added each drop individually to an Erlenmeyer flask that contained the sample solution (including the analyte to be measured) and the indicator which was added prior to the titration. ...

The aim of the study was to compare the sensitivity of the 2 assays, performed in 50 ml erlenmeyers flasks and in 25 ml long cells (disposable spectrophotometric cells with a 10 cm pathlength) respectively. ...
Abstract :Comparison is made between results of tests performed using the conventional algal growth inhibition test according to ISO 8692, in 250 ml Erlenmeyer flasks and based on laboratory algal cultures, with electronic counting of the algal cells (N), and those obtained with the Algaltoxkit-F™ tests using algal beads, long cells and Optical Density (OD) ...
If one is looking for something mundane glassware, such as graduated cylinders, pipettes, burettes, volumetric flasks, beakers and Erlenmeyer flasks Questron can be competitive with most sources for class A glassware. ...

Bromine Chloride – In an Erlenmeyer flask, 5.40g of KBr was added to 500mL of conc. HCl and allowed to dissolve for 2 hours. 7.60g of KBrO3 was slowly added to the solution. ...
Experiments were conducted in Erlenmeyer flasks under aerobic conditions, with TPH removal percentage varying from 5.9% to 25.1%, depending upon consortia type and concentration. ...
