Ocean Diagnostics has recently introduced a new technology upgrade to our [Ascension](https://oceandiagnostics.com/microplastics-sampling?utm_source=hs_email&utm_medium=email&_hsenc=p2ANqtz-8nWznPF6u4l6UnvV8PtUNsvPkWqvwvH_fm6N7stiYTixlXBOPzrZwcCz61Q7otCDVaZ741) depth sampler for microplastics applications. The previous impeller pump, which had a 400-litre maximum pump capacity, has been replaced with a new hybrid pump that can pump 2,000 litres of water in a single battery charge.* This change will help researchers meet new microplastics sampling standards.

All future Ascension orders will integrate this pump for microplastics applications. Our next Ascension production run begins this fall. [Contact our sales team](https://oceandiagnostics.com/contact-us) with questions or to place your order.
