SEC-3010 Refractometer / Viscometer

dual detector, zero dead volume, highest sensitivity, up to 80 °C,

A true Dual-Detector, refractometer and viscometer, the only one of this kind available. Not just two detectors in one common housing, but our unique patented design. The refractometer is integral component of the viscometer bridge, measurement of concentration AND viscosity take place on the exactly same sample segment, at the very same time. Compared to the more common "external" connection of the two detectors, the SEC-3010 Dual-Detector provides a factor of 2 to 5 higher sensitivity, near ZERO delay volume and unsurpassed overall performance.

GPC Viscometer
There is no need to wait for the sample "breakthrough" (the negative signal you must expect after each injection) or to adapt an "internal delay" to the number of size exclusion chromatography columns you use like other viscometer designs require.
The Dual-Detector will match any GPC/SEC application you might think of, with any solvent, at any temperature up to 80°C.

SEC-3010 Microvolume Viscometer

lowest internal volume, high sensitivity, for flow up to 0.3 mL/min,

The SEC-3010 Microvolume Viscometer is our newest development. Users asked for a viscometer able to provide the same outstanding performance as our "normal" one, but working at flow rates below 0.3 mL/min and with a maximum injection volume of 20 µL. Our Team thought about it a while, and came back with this instrument. They reached the goal and made some decisive design modifications to even improve performance.


The SEC-3010 Microvolume Viscometer surprises with fantastic 4 µL (!!) cell volume, total internal volume of only 5 mL (!) including dilution lines, and breathtaking signal to noise ratio at 0.2 mL/min flow. No limitations in terms of solvent, temperature control up to 80°C. If your GPC/SEC application requires low sample volumes and low flow rate or you are moving to green SEC and save solvent, this is the viscometer you have been looking for.

SEC-3010 Viscometer

high sensitivity, up to 80 °C,

A plain viscometer to be added to an existing GPC/SEC system, in our unique, patented bridge design. Compared to others, this viscometer offer superb sensitivity and signal/noise ratio without the drawbacks of other designs like breakthrough after each injection. Wheter you want to modernise your conventional SEC system or replace a now outdated viscometer, this is the unit to go with. Of course the SEC-3010 viscometer will operate with any solvent and at temperature up to 80°C.


You can also connect the analog output of your existing RI to it, combine the SEC-3010 viscometer with ParSEC SEC Software, and enjoy the comfort of a modern software package too.
