To set up several chemical laboratories, basic equipment is to be purchased: Scales To enable economical external maintenance of the scales, both analytical balance types (0.1mg and 1mg) should be from the same manufacturer! Analytical balance 0.1mg: Maximum weighing capacity: 120 g Readability: 0.0001 g, Linearity: 0.0002 g Reproducibility: 0.0001 g, Weighing pan: Min. Ø 90 mm Fully automatic, internal temperature and time-controlled adjustment function Large weighing interior; Height not less than 210 mm Analytical balance 1mg: Maximum weighing capacity: 420 g, readability: 0.001 g, linearity: 0.002 g, reproducibility: 0.001 g, weighing pan: min. Ø 120 mm Fully automatic, internal temperature and time-controlled adjustment function Large weighing interior; height not less than 210 mm Manual draft shield with 3 sliding doors, not verifiable Drying and heating cabinet Working temperature range up to 250 °C Air movement via convection, adjustable exhaust air flap Controller with timer function (1 min to 99 h) Rotary vane pump Since two rotary vane pumps of the same type are already available, only the rotary vane pump Rz 2.5 from Vacuubrand is being considered in order to enable economical in-house and possible external maintenance. Suction capacity (m3/h) 2.3 Ultimate vacuum abs. 2 x 10-3 Mbar Ultimate vacuum abs. with gas ballast 1 x 10-2 Mbar Small footprint up to WxHxD 160 x 390 x 300 mm With oil filling, thermal motor protection, power cable (length: 2 m), exhaust filter Fo, butterfly valve Vs 16, PP adapter (small flange DN 16 to hose shaft DN 10), clamping and centering rings. 13 single-channel microliter pipettes Mechanical air cushion pipette with adjustable variable volume 2x matching pipette carousel for 6 pipettes including quality certificates To enable economical third-party maintenance of the microliter pipettes, all should be from the same manufacturer! Please note further requirements/information in the price list!

Software for data and text analysis

The subject of the procedure is the procurement of pH and oxygen sensors. The sensors are required to repair an existing bioreactor (labfors 5, S/n: S-000127113) from Infors Ht. The probes must be preconfigured on the Labfors 5.

Framework agreement “coaching pool for the Pogs”

Materials and chemicals for genotyping

Framework Agreement on Tax Advisory Services (Section 2b UStG)

The subject of the procedure is the procurement of a phase-stable optical chopper, including a controller with synchronization option of an external signal, preferably MC2000B-EC - Optical Chopper System With MC1F10HP 10/100 Slot (36°) Chopper Blade, 230 Vac Power Cord, or equivalent. The chopper is required in ultrashort-time spectroscopy, for very small sample volumes (aqueous and organic solutions, protein samples) for applications in transient UV/VIS spectroscopy and when operating a liquid jet system. The phase-stable optical chopper and the controller with synchronization option of an external signal must meet the following specifications/parameters: - Frequency range from 100 Hz to 2000 Hz. - Phase drift less than 1° - Input signal for synchronization via BNC connection. - Output signal for reading the chopper position via BNC
