GE BIO-SCIENCES VIVASPIN™ SAMPLE CONCENTRATORS
Vivaspin provides fast, nondenaturing concentration of biological samples by membrane ultrafiltration. The entire process is carried out in a single tube ensuring convenient sample handling and reduced sample loss. Recovery of the target molecule typically exceeds 95%. Patented dead-stop technology ensures that samples cannot be concentrated to dryness. The vertical polyethersulfone membrane minimizes membrane blockage and tolerates high flow rates.
