laboratoriumartefacten

Laboratoriumartefacten refers to objects or materials that are unintentionally introduced into a sample or experimental setup during the process of laboratory work. These artefacts can originate from a variety of sources and can significantly impact the accuracy and reliability of experimental results. Common sources include contamination from glassware, reagents, instruments, or the laboratory environment itself. Dust particles, airborne microbes, or residual chemicals can all act as artefacts. Human error, such as improper handling or cleaning procedures, is also a frequent contributor. The nature of the artefact can range from microscopic particles to macroscopic debris. Identifying and mitigating laboratory artefacts is a critical aspect of good laboratory practice. Techniques for minimizing artefacts involve meticulous cleaning of equipment, using high-purity reagents, working in controlled environments like fume hoods or cleanrooms, and implementing strict sterile techniques when necessary. Proper documentation of the experimental procedure, including any observed anomalies, is also important for troubleshooting and identifying potential artefacts. The presence of artefacts can lead to false positives, false negatives, or altered measurements, necessitating careful consideration during data analysis and interpretation.
