Multiskan Ascent 96/384
Multiskan Ascent 96/384 Plate Reader
Multiskan Ascent offers superior photometric measurement performance for 96- and 384-well plates. This instrument reads the plate rapidly and can be connected to robotic systems for increased throughput in photometric reading.

Excellent optical performance for 96- and 384-well plates

The high-quality optical system of the Multiskan Ascent ensures excellent reproducibility, accuracy and reliable results. The unit is linear up to an outstanding 4 Abs. units with 96-well plates and up to 3 Abs. units with 384-well plates, eliminating the need to dilute samples. This saves time in obtaining sample results.

A recent validation study in a high-throughput (HTS) environment with 384-well plates showed excellent consistency of the signal across all wells in the plate (low intraplate variation). No bias was observed in the IC50 as a result of curves being set up in different parts of the plate or between two separate plates (interplate variation). A good correlation was also observed in two different experiments using the same group of compounds (low interassay variation).

Fast measurements

Multiskan Ascent provides not only extreme accuracy and precision, but also very rapid measurements: It takes only 9 seconds to measure a 96-well plate and only 20 seconds to measure a 384-well plate. These values can have a noticeable effect on a laboratory’s throughput.

Easy and flexible robot integration

Another feature that makes Multiskan Ascent ideal for high-throughput environments is its simple and easy robot integration. This unit is designed for integration, which can increase walk-away reading capacity to 20 or 80 microplates.

Optional incubation

An optional internal incubator can be included for assays requiring temperature control. Temperature can reach up to 50°C.
