In Vitro Core

TopCount NXTTM Microplate Scintillation and Luminescence Counter

The In Vitro Core’s TopCount NXTTM analyzes six at a time, and counts samples in 96- and 384-well microplates, as well as microcentrifuge tubes. The external plate stacker allows multiple assay plates for a high unattended counting capacity. The system automatically controls the counting chamber temperature to ensure a stable and reproducible counting environment. The TopCount NXTTM can be used for Cell proliferation, Receptor binding assay, Solid Phase RIA/LIA, Reporter gene assays, 51Cr release assays, HPLC fraction analysis and Scintillation Proximity Assays (SPA).

HERMLE LabNet Z323K Centrifuge

This high performance centrifuge has high speed rotors capable of producing up to 26,810 x g. Higher speed and g-force allow this centrifuge to be used in a biological lab setting. Parameters are set using easy turn knobs while their values are shown on large digital displays. Speed can be set and displayed in rpm or rcf. It has a radius-correction feature, and braking intensity can be set to ten different levels. There is also a refrigeration system internally, so heating or cooling can take place inside the centrifuge.
