Proper sample preparation, such as homogenization
of samples for analysis and particle size analysis of solid substances, can impact assay
throughput, quality of data, and cost of analysis.
Laboratory mills, grinders, jaw
crushers, and presses are used for sample prep of solid samples.
Automated
dilution and dosage systems, for use with both solid and liquid samples, ensure accurate
weight/weight or weight/volume ratios.
Manual and automated sample prep equipment
is used in chemical, biotech, medical, forensic, and environmental analysis labs.
What Are Considerations When Choosing Sample Preparation Equipment?
The final result you hope to obtain from the sample will help narrow down the choice of
instrument.
With laboratory grinders, for example, cutting, shearing, pressure,
friction, or impact force may be used to obtain a final fineness as low as 0.1 µm.
Ultrasonic homogenizers or sonicators for use with fluid samples can achieve
speeds of 35,000 rpm.
