Sample drying and grinding (plant) | Research Analytical Laboratory

Sample drying and grinding (plant) Moist plant samples are dried at 65°C until crisp. Samples are then passed through a stainless steel grinder with 20 mesh sieve and mixed thoroughly. Ground samples can be stored at room temperature, but must be redried at 65°C for 2 hours and cooled in a desiccator before weighing for analysis.
