ATTO WSL-1565 Kronos HT-Bioluminescence measurement system for living cell and tissues

Buy ATTO products from MSE Supplies at the best Value.

The Kronos HT is performing to detect high sensitivity for dim and weak luminescence consecutively in culture samples such as cells and tissues in 24 well plates for a long time. 96 well plates and 35 mm dishes also applicable.

Features

Sample stage is in the incubation chamber in which temperature and CO2 gas concentration is controlled and humidity is kept >90%RH.
24・96 wells micro plate applicable.
Long-time detection available *1hour～30days
2 plates are measured by 2 PMTs (one PMT to one plate)
Plates are not moved, PMTs are moved to each well. > No shaking cells, so less damage to delicate cells and applicable to floating cells such as hematocytes.
PMTs are cooled to 10℃ > The dark noise is lower.
Built in filters for Multi-color luciferase assay

MSE Supplies is an authorized distributor of ATTO products.
