To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** Hi Tom Thanks for your suggestion. We use the Zeiss oil for water lens routinely and it works very well as long as one doesnt try to image a whole multiwell plate. Oil (normal or for water lenses) is too viscous for large areas. It collects at places and goes missing at others. We have tried this a lot without success. The only option we have found to combine higher throughput and high resolution is to use a water objective. It works really nicely with glass bottom plates but now we also acquire time lapses, so I guess the only way to go is to have a water refill system. Hence my query... Does anyone have any experience with this type of protocols?

I've also wondered if silanizing the bottom of the plate to make it more hydrophobic would give a more uniform oil distribution.

To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** G'day Sylvie, I've been building my own "lens re-watering" systems for water immersion objectives for about ten years. Back then I let most, if not all, the microscope companies know about it. They are very easy to build. My version uses a plastic pipette to add water via gravity feed. Any excess flow is sucked away via a peristaltic pump. All you need is some thin PE tubing (eg. Polyethylene Tubing I.D. = 0.58mm O.D. 0.96mm) Actual diameters not important, anything roughly those dimensions will do. You very slowly warm the tubing by holding it beside (NOT above), and about 5cm away from the flame of a Bunsen burner. Rotating slowly between thumbs and forefingers. Don't heat too quickly, slower the better. Keep the tubing under mild tension as you heat. As soon as it starts to stretch, remove from heat, BEFORE it breaks. That's the tricky part that needs practise. Don't throw away the failures, they are useful too, more later. Cut the PE tubing at it's thinnest point with a scalpel. You now have two plastic pipettes, that will not damage your lens. The failures end up curved, you can use these to suck away excess water (you'll have no shortage of these!) You now want to find a short length of some very large diameter Poly Vinyl tubing that will fit snugly around the top of your objective. eg. recently for a Leica WI lens we used approx. 30mm internal diameter tubing. Cut a thin slice of this tubing so that you have a ring, you can then fit this around the top of your objective, and have it just a little higher than the edges of the objective so that it forms a "moat", for those lenses that don't have a "moat". For lenses that do have a moat, allow the tubing to be just slightly proud of the moat. It should not be so large as to get in the way of the stage or your specimen. A trick taught to me by my colleague Robin Cole from the Ludwig: If the tubing is a little too large in diameter, you can shrink a small section by tightening a hose clamp around it (not when it is on an objective). Then heat the tubing (and clamp) with a heat gun (or very hot water might work too). Remove from heat, once cooled down to room temp., remove the hose clamp. Voila! Smaller tubing. Once fitted around the top of your objective, using an 18 Gauge hypodermic needle and a drilling motion with thumb and forefinger, drill two small holes through the very top of the tubing that now forms a moat. These holes will accommodate your re-watering pipette and suction tube. The pipette should be inserted so that it is just adjacent to the flat part of the objective that has the top lens. In other words you don't need it right next to the lens, a little way back so that it does not get banged against the coverslip. Capillary action will ensure the water will go between lens and coverslip. Sometimes you may want to use a little double sided tape to keep everything out of the way. Rig up a gravity feed with a 50ml syringe (without plunger) and 3-Way stop cock. I also use a 2ml syringe (with plunger) in the other port of the stop cock to prime the system, and for short term experiments eg, 2 hours you can use this to add water manually every 30 min. For longer term experiments eg. overnight, use gravity to do the work. The "failures"are bent and useful. Take one of these and insert through the other hole drilled into the moat, and connect to a peristaltic pump. Any excess flow onto the lens will spill into the moat, and as it builds up will be harmlessly sucked away via the pump into a beaker. In this way you don't need to carefully regulate flow rates. I have a PowerPoint describing this better and will send it via email to anyone who asks. I was going to write this up as a technique paper years ago, but the release of oils the same refractive index as water, and later commercial re-watering systems stopped me from doing so. I guess J. Microsc. may still be interested as a short Tech note. What do people think? Email me if you want the Re-watering gizmo How-to PowerPoint. We have successfully used this on time-lapse experiments at 37Deg C for three days continuous. Topping up the 50ml syringe each morning just to be sure. Cheers Steve Stephen H.

To join, leave or search the confocal microscopy listserv, go to: http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy ***** Interested parties I just received information from a company that makes a device for this application. They were not responding to this thread but after a review of their web site I saw that they have addressed this problem. I have never used it but I did look into the technology. Apparently it uses a new kind of micro-pump that uses Piezo deflection of a membrane to induce nanoflow. It looks good and I am waiting to get a demo of this in my lab. It looks to me that this is the company that makes a water replenishment system for Leica. They might have a device for other manufacturers objectives but I don't know. I am still looking into it.

I think this would be a very useful paper to have available. I think it would be well worth your time (and great for the rest of us!) doing a quick write up with a few diagrams/pictures to make clear exactly how it works. Thanks, Ian |
