DVD1260 Viscosimeter
The SECcurity DVD1260 four capillary viscometer lowers the detection limit with an asymmetric bridge design. While other viscometers dilute 50% of the sample in the solvent path, the DVD1260 dilutes only 20% of the sample in the solvent path. 80% of the samples run through the sample path leading to an unparalleled signal/noise ratio without any digital signal processing.
Low-noise electronics combined with high-sensitivity pressure transducers results in excellent peak shapes and high signal linearity. The use of reservoirs (instead of hold-up columns) eliminates viscometer modifications when the column setup changes and reduces the analysis time to 50% compared with other viscometers.
The detector DVD1260 design allows seamless integration into any GPC/SEC or FFF System.
