C-Trap Dymo Short Tether Package Upgrade

The University at Buffalo intends to make an award under our discretionary authority, pursuant to NYS Education Law §355 (5) (a), which is up to $125,000, for a C-Trap Dymo Short Tether Package upgrade. The Short Tether upgrade must include the minimum requirements and be compatible with the existing C-Trap Dymo 300 Optical Tweezer-Fluorescence Microscope system and Bluelake software. A sealed bid will not be held. If you are interested in providing a proposal for the above commodity or a university approved equivalent, you must contact the appropriately designated Campus contact in this advertisement within 15 business days of this Advertisement Notice.
