Hi, and thanks in advance for your input. Do you have any recommendations for a lyophilizer brand and/or model for EV preservation from cell culture media? I'm looking for an R&d to small scale production freeze dryer. We need is a reliable, reproducible unit, that we can produce in. We’ve had a bad experience with one instrument terms of unit performance, reproducibility and customer support, so we are returning it, and we are looking for a replacement. Thank you!
