[Confocal] spinning disc 100x objective maltreatment
by Daniel Van Damme 26 Oct '16

26 Oct '16

Dear confocal users, The 100x objective of our spinning disc is broken, there is immersion oil inside the objective. We currently have a demo lens from Nikon which allows us to keep working while they are checking the cost to repair our objective. Oil inside the objective can only be caused by using too much immersion oil which has ran down the body of the lens and in between the body and the retractive top part. There is no alternative way to explain this than malpractice and this should not happen. The objectives are one of the most expensive parts of any microscope and anything abnormal should be reported to Evelien or me instantly. We will take measures to better protect the objectives, and at least from now on, everyone using this 100x objective should clean the lens with a soft tissue and lens paper whenever you change the sample. Also, when you are finished, the 100x objective should be cleaned with the lens cleaning solution (on a soft tissue followed by lens cleaning paper).

[Confocal] Zeiss710 sensitivity issue
by Daniel Van Damme 20 Oct '16

20 Oct '16

Dear all, I would like to remind everyone who uses the confocals to subscribe to the confocal mailing list (you can do this easily via intranet). Otherwise, you might miss future mails concerning the confocals (now I have included research, but this should be avoided to reduce spamming people who this does not concern). The Zeiss710 currently has a sensitivity issue as the amount of laser power required to image is abnormally high (40%). I have contacted Zeiss and will let you know when it will be solved. In the meantime, do take into account that you might need to use more laser power to image and that this will likely cause bleaching of your sample. Also, the epifluorescence light bulb has exceeded its life time and I will replace it. In the future, it would be nice however that when you notice this (old bulb flashing on the controller), to notify me or Evelien. How else can we know when to replace/order a new bulb? have fun imaging, d Daniel Van Damme - Expert scientist Advanced Live Cell Imaging VIB Department of Plant Systems Biology Ghent University Technologiepark 927 - 9052 Ghent - Belgium Tel. +32(0)9 331 39 13 www.psb.ugent.be

[Confocal] Fwd: Zeiss exciter issues: laser and fluorescence lamp

> Dear all, > I noticed that the argon laser is not working optimal anymore . The plasm is > almost degrades, which makes it unusable at the normal output (= position of > the small wheel just before the green light turns into the red light). > This wheel is now at a position that gives the best output. (approx around 4,7 > A, whereas normally this is around 6A). Please don't change, I put a tape > around it. Above this position there is no output at all. (you should see a > purple light, not an orange light). > A new laser is ordered and will be installed. > Also the lamp of the fluorescence lamp has been changed . This lamp was already > a lot above this maximum lifetime and caused a lot of noise. Also the lamp > sometimes felt out during the experiment. > Dued to a broken collector glas inside this lamphouse, it was impossible to make > a proper alignment with the new lamp. The Zeiss person will look into this > tomorrow to try to get it as good as possible for the moment until the part is > repaired. > I would like to address once more to contact Daniel or me whenever you encounter > some problems. > Thanks in advance, > Greetings, > Evelien > Evelien Mylle - Lab Manager / Technician > Advanced Live Cell Imaging > VIB Department of Plant Systems Biology > Ghent University > Technologiepark 927 - 9052 Ghent - Belgium > Tel. +32(0)9 331 39 34 > www.psb.ugent.be
