Thames Restek has expanded its product portfolio with an increased range of Restek's Quechers SPE tubes.
The tubes are now available in three centrifuge sizes to meet the needs of extraction and clean-up of pesticide residue samples from food products.
Sizes on offer are 2ml, 15ml and 50ml, which contain ultra-pure pre-weighed adsorbent mixes.
The Quechers tubes enable a fourfold increase in sample throughput to be achieved with a fourfold decrease in material costs, according to the company.
The Quechers SPE tubes have been specifically designed for use with the Quechers method of extraction and clean-up using DSPE, which was developed by the US Department of Agriculture Eastern Regional Research Center.
Free sample packs of Restek's Quechers SPE tubes are available through Thames Restek.
