Special Accessory for Small Samples

Precious samples for particle size analysis need no longer be wasted with the launch of a new small-volume cell by Brookhaven Instruments. This cell requires only 180 microliters (μL) or less of sample material – usually 2-3 mL of suspension are needed to make measurements. The small-volume cell is particularly relevant for pharmaceutical research involving peptides, […]
