® Titrette and Digital Burette (all models) Testing Instructions (SOP) May 2013 1. Introduction The standard ISO DIS 8655 describes both the design and the testing of bottle-top burette. The following Testing Instructions describe how to apply the ISO standard in practice. We recommend a testing every 3-12 months. This interval may be adjusted to individual requirements. For example, when working very frequently or when using aggressive media, the instrument should be tested more frequently. These Instructions may also be ...

CHEM 311L Quantitative Analysis Laboratory Revision 2.3 Calibration of Volumetric Glassware In this laboratory exercise, we will calibrate the three types of glassware typically used by an analytical chemist; a volumetric flask, a volumetric pipet and a buret. Over the course of this semester, we will use these tools extensively when performing Gravimetric and Titrimetric Analyses. In order to avoid introducing Systematic Errors into our measurements, each of these instruments must be properly calibrated. And, to reduce the Random ...
