The life sciences field is an important part of the modern medical laboratory, navigating research, production, and quality assurance for sample and solution preparation, dilution, and overall workflow. Achieving precise data measurements with scale use is crucial within this highly regulated environment, providing the right solution for accuracy, measurement reliability, user comfort, and safety. Being noncompliant can lead to expensive and labor-intensive corrections as well as a need for reputation repair when confidence in laboratory data is tarnished.
Using high-precision scales, life science professionals are better equipped to provide data that’s correct and on target. Incorporating high-quality scales in the life sciences laboratory provides problem-solving solutions that are engineered for a more efficient, accurate, and streamlined environment. This starts the moment sample preparation begins using a high-precision scale.
Volumetric sample preparation
Life sciences laboratories that rely on traditional methods opt for volumetric sample preparation. Here, samples are typically weighed directly into a volumetric flask and the flask is then filled with solvent. Weighing papers may be used, transferring the sample to a volumetric flask for dissolution. Traditional methods do carry more risk of errors. These can be minimized by preparing larger volumes of sample solution for easier weighing as well as following proper processing protocols.
Gravimetric Sample Preparation
Improved instrumentation and software have provided dramatic improvements in sample analysis and data processing for life sciences. This includes the gravimetric sample preparation approach, offering greater accuracy with less uncertainty of measurement to minimize and even eliminate many of the issues of the past.
The gravimetric method – weighing both the solid and the diluent – enables a specified concentration to be prepared accurately and precisely, reducing sample variability and impacting positively on the number of instances of out-of-specification results. In addition, fully automated powder and liquid dispensing systems eliminate the use of weighing papers and volumetric flasks, helping to further reduce laboratory errors and increase efficiency.
Solution Preparation and Dilutions
Once a sample is prepared, the process is far from complete. Life sciences laboratories continue working with reagents, buffers, solutions, instrument performance verification, and calibration determination. As for performing dilutions, following the gravimetric approach helps avoid errors while pinpointing accurate weight.
Life sciences laboratory work may include a workflow box that customizes and guides every step of the workflow process for high-performing data integration. For example, a clearly visible green light lets you know when it’s safe to start. Warning lights and other determinants can also be included with customization features.
