Microplastic extraction from beach sediments

The method presented in this video was optimized for samples that were collected on beaches. And contain a high amount of twigs, leaves, drift wood and other organic material. This method is also applicable for samples from other sediments like soil for example. The goal is a sample as clean as possible. In this video we show a step by step guide how to remove drift wood and other material from beach samples. 00:00 Introduction 00:39 Density separation with a saturated salt solution (NaCl) 04:04 Density separation with ethanol 06:28 Removal of drift wood using a vacuum pump 08:42 Results and final steps If you want to learn more about our research, please visit our website: https://microplasticresearch.wordpres...
