Please direct all requests and/or questions to Kim Sparks before sending samples. Be sure to take time to ensure samples are packaged correctly and that the necessary precautions have been taken (i.e. frozen samples packed with dry ice). It is recommended that a secure carrier be used for shipping samples, so that you can track samples in case they do not arrive at COIL in a timely manner. Make sure samples meet prep guidelines.
