Desalting and Buffer Exchange with Sartorius Ultrafiltration Concentrators
Forget overnight dialysis – Exchange your buffer gently within minutes
During the preparation of biological samples, buffer exchange is an essential step, as it prepares the sample for downstream applications or enables subsequent long-term storage. The traditional method for buffer exchange is dialysis, but, as it relies on passive diffusion, it can take up to 24 hours.
You can substantially reduce the time needed for exchanging your buffer by applying Sartorius ultrafiltration devices for diafiltration. Whether applying centrifugal force in Vivaspin or make use of the cross flow method with Vivaflow for larger volumes; it’s a great save of time and you can get the job done within minutes.
