Plovdivski universitet "Paisii Hilendarski" has launched a multi-lot specialised devices contract for its NPD subdivision, bringing together air-quality monitoring stations, 3D printing facilities and educational kits. The mix of environmental sensors and hands-on teaching tools shows how a university procurement can link clean-air research with STEM skills development.
Published on 4th December 2025, the contract notice sets out plans to supply various specialised devices and apparatus in separate lots for the NPD subdivision of Plovdivski universitet "Paisii Hilendarski" (PU "Paisii Hilendarski"). Among the lots are a stationary station for monitoring air quality and an autonomous system for monitoring meteorological parameters and air quality, alongside other laboratory and teaching equipment described in the technical documentation.
By pairing a fixed air-quality station with an autonomous monitoring system, the university is positioning its NPD subdivision to gather data under a range of conditions. The combination offers scope to track local meteorology and pollution levels in a consistent way, while also experimenting with more flexible or mobile deployments through the autonomous unit.
The emphasis on environmental monitoring sits within a broader local push to invest in clean‑air and waste infrastructure. In July 2025, the municipal enterprise Chistota in Panagyurishte launched a procurement for waste containers of various types, while in December 2025 Plovdiv Municipality published a tender for specialised equipment including waste collection vehicles, a loader excavator, tractors and wood chipping machines. Against that backdrop, the university’s order focuses on the measurement side of environmental management, generating the data that can underpin future policy and teaching.
The same multi‑lot contract also covers 3D printing equipment and educational kits for the NPD subdivision. Procuring fabrication tools, kits and environmental sensors together suggests an effort to build integrated STEM environments, where students can observe air‑quality data and work with modern prototyping equipment in the same setting.
Across Bulgaria, schools and dedicated centres are making similar moves. In July 2025, Sredno uchilishte "Naiden Gerov" in Plovdiv issued a procurement for STEM centre equipment covering delivery, installation, training and warranty support across three lots. Around the same time, PGSAG "Penyo Penov" in Ruse sought to establish a school STEM environment through a tender for computer equipment and peripheral devices, with explicit reference to meeting environmental standards.
The push is not limited to individual schools. In October 2025, the Natsionalen STEM tsentar went to market for audiovisual and photography equipment through a contract notice that combines delivery and installation with training in how to operate the systems and warranty support. This focus on complete packages – hardware plus skills – mirrors the way the Plovdiv university’s NPD subdivision is equipping itself with both instruments and teaching kits.
Elsewhere in Europe, higher education providers are assembling similarly diverse technology portfolios. In August 2025, Hungarian institution Gábor Dénes Egyetem published a procurement for high‑tech laboratory tools ranging from drones and imaging devices to robots, IT equipment and educational kits, evaluated on the basis of lowest price. In October 2025, Veszprémi Szakképzési Centrum followed with a four‑lot tender for vocational training equipment, including pneumatic kits, chemical instruments and a vehicle propulsion laboratory, with installation and training for staff built into the scope.
The NPD subdivision’s order also fits a wider pattern of Bulgarian universities and research institutes using public procurement to modernise laboratories. In July 2025, Sofiyski universitet "Sv. Kliment Ohridski" issued a laboratory equipment procurement split into ten lots, covering precision scales, autoclaves, microscopes and other devices, all to be delivered, installed, commissioned and supported under warranty.
In August 2025, the Institut po molekulyarna biologiya "Akademik Rumen Tsanev" sought to purchase a broad suite of systems through a 22‑lot tender that spans PCR machines, microscopes and centrifuges, all tied to detailed technical requirements and safety standards. By November 2025, the Institut po polimeri – BAN had followed with a two‑lot procurement for a particle size and zeta potential measuring device and a thermogravimetric analysis system, both required to comply with European safety standards and precise specifications.
Technical performance and service conditions are also central in engineering and medical research. Tehnicheski universitet in Sofia published a notice for new measurement instruments and systems in August 2025, stipulating a warranty period of at least 24 months and a maximum delivery time of 90 days. In November 2025, Meditsinski universitet – Plovdiv tendered for a patch‑clamp system, texture analyser and 3D DLP bioprinter to support scientific projects, echoing the emphasis on 3D technologies in the Plovdiv NPD subdivision’s own order.
Health‑sector teaching and research institutions add another layer. Also in July 2025, Meditsinski universitet – Varna published a procurement for equipment, tools and consumables funded by its Science Fund, including installation, commissioning and staff training. On the same date, the Faculty of Dental Medicine at Meditsinski universitet – Sofia issued a tender for dental equipment that similarly combines delivery and installation with training and warranty maintenance.
Taken together, these notices highlight a procurement model built around multiple lots, tightly specified instruments and bundled services such as installation, commissioning, training and ongoing support. The NPD subdivision contract at PU "Paisii Hilendarski" fits within that model, but adds a distinctive focus on air‑quality monitoring alongside 3D printing and teaching kits.
The summary of the Plovdiv contract does not spell out individual performance thresholds for the air‑quality station or the autonomous monitoring system; those details sit in the technical documentation. However, similar laboratory and STEM tenders across Bulgaria and neighbouring countries point to increasingly demanding specifications, explicit safety requirements and formalised warranty obligations.
As the Plovdiv university moves from notice to contract award and implementation, the key questions will be how its NPD subdivision integrates fixed and autonomous air‑quality monitoring into research and teaching, and how the new 3D printing and educational kits are used alongside the sensors. For suppliers of environmental monitoring systems, laboratory instruments and STEM equipment, the contract underlines continuing demand from public‑sector education buyers looking to strengthen both their data and their teaching infrastructure in a single procurement.
