Data handling work station
HeraCell 150i with standard settings
Currently, we provide a total of six shelves in two incubators (HeraCell 150i).
Standard settings: 37°C, 5% CO2.
Diverging settings can be arranged.
Optional with orbital shaking plate.
In addition, we can provide incubation in a compact table top CO2 incubator (Midi40).
Table top incubator
For microbiological work including all standard plastic ware and instruments.
HeraSafe KS laminar flow safety cabinet
For generating fresh tissue slices a sequentially ordered set of equipment, including consumables, is available:
Anaesthesia area
Induction boxes (ambient air)
Peristaltic pump for transcardiac perfusion
Dissection place for organ removal and blocking
Vibration microtome for tissue slicing
Warm water bath for slice incubation
Supply of carbogen at all sections.
Acute slice preparation work flow station
For generating artificial cerebrospinal fluids and other soultions a fine scale, osmometer and pH meter (Seven Compact by Mettler Toledo) with a semi-micro electrode is available.
Solution mixing and testing work space
The work station for surface treatments of the recording arrays (cleaning, hydrophilization) includes, amongst others, a plasma cleaner and UV curer. The plasma cleaner is in the process of establishment and will be operated with pure oxygen.
Array maintenance work station
Electrotechnical and fine mechanical work station
A work station with soldering iron, UV curing light and further fine mechanical and electrotechnical equipment is available.
The following recording devices are in the process of establishment:
