Is the FastPrep®-24 System designed for the homogenization of hair samples for forensic toxicology analysis?
The FastPrep®-24 instrument combined with the TeenPrep™ adapter has been successfully used for the lysis of hair samples prior to drug analysis. Uncut hair samples are added to 15ml Lysing Matrix tubes containing 8 large 1/4 inch ceramic spheres and 4 steel beads, samples are homogenized 2 times for 50 seconds at speed 6.0 m/s. After the homogenization step, methanol is added to the powder-like homogenate for drug extraction. Recommendations for the homogenization of small mamounts of animal and plant tissues (less than 10mg) The homogenization of sample amounts lower than 10mg is performed with Lysing Matrix D tubes after removal of half of the ceramic beads from the tubes. Samples are disrupted at a speed setting of 6.0 m/s for 30 seconds.
