96-well SLE (Solid Supported Liquid-Liquid Extraction) Plate

The SLE Solid Supported Liquid-Liquid Extraction is an efficient and economical new method, which can extract the target compound from the water phase in two steps. Copure^® 96-well SLE plate adopts special technology to process the materials. The material adopts porousdiatomite filler with high specific surface area and strong chemical inertia as liquid-liquid distribution carrier. It can replace the most of traditional liquid-liquid extraction methods, and it has higher extraction efficiency and stability. This method is widely used in food safety, environmental monitoring, clinical diagnosis and industrial product detection.

Features

• Replace the traditional liquid-liquid extraction, provide an ideal surface of liquid-liquid extraction for  target analytes
• Avoid the emulsions phenomenon
• The operation of SLE is very simple: load-elute,  saving solvent and time, easy to automate
• Better reproducibility and higher recovery
• Lower detection limit and higher sensitivity
