Bulgaria – Electrodes – Доставка на електроди и консумативи за рН- метри, оксиметри, апарати за електропроводимост (лабораторни и преносими) и автоматични титратори

Delivery of electrodes and consumables for apparatuses (laboratory and portable) for measurement, necessary for daily laboratory activities. The apparatuses for determining the characteristics of active reaction (pH), electrical conductivity, dissolved oxygen, and specific anions and cations are among the most frequently used technical means in the laboratories of the Institute of Oceanology at the Bulgarian Academy of Sciences (IO-BAS) during field tests of water samples (surface, groundwater, wastewater, and marine) and laboratory tests of samples from water, soil, sediments, suspensions, and waste products. To determine the above-mentioned characteristics with the required analytical accuracy for reporting the results of the conducted tests, it is necessary to purchase specific measuring cells (electrodes), through which the measurement process is ensured. It is for this reason that a public procurement contract with the subject: "Delivery of electrodes and consumables for pH meters, oxymeters, electrical conductivity apparatuses (laboratory and portable) and automatic titrators" must be entrusted. The delivery of various types of electrodes and the necessary consumables for their maintenance is dictated by the fact that they have a relatively short service life, after which their technical parameters deteriorate and the conduct of accurate measurements is impossible, while the consumables are necessary to maintain the electrodes in their optimal measurement parameters within their maximum shelf life.

The subject of the contract is delivery. The public procurement is divided into five distinct positions as follows:

Distinct Position No. 1 - Electrodes compatible with WTW devices

Distinct Position No. 2 - Electrodes compatible with Thermo Fisher Scientific Orion Star devices

Distinct Position No. 3 - Electrodes compatible with Metrohm apparatuses

Distinct Position No. 4 - Electrodes compatible with Agilent apparatuses

Distinct Position No. 5 - Consumables for the maintenance of electrodes
