We are grateful to the Veterinary Faculty Utrecht to support an upgrade for the NIKON A1R system. Many users will benefit from this upgrade since it will vastly improve confocal imaging speeds. The upgrade will be performed around the last week of May 2019.
The TOKAI HIT heater for lenses on the NIKON system is repaired. Please be careful wrapping the foil around the lenses, the fit should be tight but do not pull the wiring or deform the aluminium foil while wrapping.
Unfortunately, the TOKAI hit lens heater is broken again. We are in contact with the Japanese supplier but it may take some time for it to be repaired (it needs to be sent to Japan). We have imaged live cells without the heater overnight without any problems, yet the temperature at the lens spot will be several degrees below the set temperature. Contact CCI staff if you intent to install the hairdryer for additional heating.
The TOKAI hit objective heater is complete again. Be careful when changing objectives when the velcro is around it. The connecting wires can be dislodged from the connectors by these fast movements. Also, the aluminium inner surface is fragile be carefull when you wrap te velcro around an objective.
The objective heater for live cell imaging on the NIKON A1R-STORM system is broken. The thermocouple is being replaced. For short term time lapse (and vibration insensitive imaging) you can use the hair dryer to warm the lower part of the microscope.
The attachment of the different adapters for the TOKAI hit heating chamber on the A1R NIKON / STORM microscope has been changed. Magnets have been glued onto the MCL-piezo stepper adapter to snap sample holders by pairing magnets. Place a sample holder and carefully put the supplied separate 12 mm diameter plate magnets over the front-left and back-right corners.
The Bio-Imaging Utrecht community organizes an ImageJ/FIJI workshop for experienced users on Tuesday the 4th of April. Previous sessions were very well appreciated and they allow you to interact with experts in IJ coding. You can learn image analyses automation and the experts can help you find, tweak and apply the proper plugin(s) for you specific question. It is highly advised for microscopists who use FIJI but have problems overseeing the large analyses possibilities offered by the platform. Register using the form attached here (deadline 17th March)
A new 20x Plan Achromat VC objective (air) has arrived and is installed on the NIKON A1R/STORM machine. The multi immersion objective is removed from the turret but will remain available for users (ask CCI staff if you prefer to use it). The new objective is more widely applicable, has a working distance of 1 mm, a NA of 0.75 and should work well with the perfect focus system. We will test it in the coming period.
Today, the NIS elements software on the NIKON A1R/STORM system has been updated to the newest version for the NIS suite (4.5) and the STORM module (4.1). In STORM, Z stacking features, fiducial marker integration and sequential recordings on identical positions can be performed, potentially on regions in live cells. In addtition, the 405 laser was re-aligned and set at a higher level in the startup script to allow better imaging in the UV region. Users should take care that this laser setting is different from their previous sessions.
The storage for gas tanks (CO2, N2) in the CCI corridor has been replaced and moved to make space for the flow cabinet that will be positionned in the recess behind it. Beware that the corridor has become more shallow because of the move.
