Procedure: Contract award without prior publication
CPV classification: 38519200 | 38519400 | 38519650 | 38970000 | 45214630
Estimated value: 300000 EUR

Technical requirements: The contracting authority has investigated whether there are suppliers on the market that can meet the specific requirements for the microscope for the research.
We found that the Dragonfly system (Andor Technology Ltd) is the only setup that combines the required needed specification needed for our applications. Among the available options on the Andor Dragonfly 202 scan unit, the spinning disk confocal microscope option is our required choice as it allows simultaneously high-speed imaging, which is compatible with DNA-PAINT, livecell imaging and enables characterisation of thick samples through background rejection.
The goal of this voluntary transparency notice is is to inform the market that TU Delft intends to conclude an agreement with Andor. Based on market research, it appears that Andor is the only appropriate supplier on the market that can meet our technical specifications. It has been unequivocally established that there is no competition for this purchase for technical reasons.
The contracting authority will observe a standstill period of at least 20 (twenty) calendar days starting after the date of publishing this announcement (from 9 July 2021 until 2 August 2021).
Any supplier who disagrees with this decision may appeal against it within the aforementioned period in preliminary relief proceedings before the Preliminary Relief Court in The Hague. After this standstill period, rights to object expire.
1) Spinning disc confocal scanner on an upright microscope to be used with water dipping lenses delivering optical sectioning of <500 nm;
4) High power widefield illumination laser engine (405, 488, 561,640,730 nm) for high power laser (> 700 mW) applications like DNA-PAINT
5) Surfaces capable of ‘Massive Model Rendering’ to interactively render surfaces of 100GB size or larger;
During the vendor research, multiple microscope systems and samples were tested from various ongoing projects related to the development of engineered micro/meso-scale cell environments (eg neurons, bones, cancer). The scientists have found that the Dragonfly system (Andor Technology Ltd) is the only setup that combines the required specifications. Of the options available on the Andor Dragonfly 202 scanning unit, the spinning disk confocal microscope option is required as it enables simultaneous high-speed imaging, which is compatible with DNAPAINT, enables live cell imaging and characterisation of thick samples by
