Dear All, I have a Mettler Toledo analytical balance that has been recently been calibrated and is giving me some problems. When I attempt to weigh anything,...
BM, Who HASN'T encountered this problem? Ugh! I sympathize...it can be very frustrating at times. Personally, I've never had any luck using a static gun, and...
Don't discount the possibility of a problem with the balance, either mechanical or electronic. A service call may be in order. R. McIntosh ... From: B M...

I thought that might've been the culprit initially but then I attempted weighing empty glass vials with the same result. ... ...
BM, The symptoms you describe sound so much like static that it is hard to believe it could be anything else - especially since the Mettler service rep...

I seem to recall that the Haug unit offers a flexible point ionization unit in addition to a U-shaped pass through unit (both can be used at the same time)....

Thank you all for your insightful suggestions. My balance seems to be giving good results now. The level of static electricity that affects the balance in...
On behalf of the Microplate Standards Development Committee (MSDC) of the Society for Biomolecular Screening, I would like to let you know that on January 8,...
Are there technologies to plate transformed E.coli on to Genetix plates using Robotic arms and pipeting channels? I especially looking for ways to spread the...
Scinomix has built custom automation in the past for this specific application. Please contact me if you would like more details. Regards, Russ Leeker Phone:...
Dear Ram, I shall be interested to see the replies to this thread you have started. Here at Genetix we spread E.coli using sterile glass beads. We manually...

Dear Ram Allegro Technologies have successfully plated cells onto Genetix plates using the Equator low volume pipetting systems in relation to optimizing the ...
BioTX Automation has also developed a system to automate this type of process in the past. An example using an Epson SCARA robot is displayed on our home page....
Does anybody have any ideas on precision plate locators for positioning 1536 well plates more accurately on a liquid handling xyz platform? The standard dowel...
Can anybody offer any advise on a method that I can use to help cool a well plate while in position on a xyz platform. Can I get something off the shelf? I...
Hello, I'm not too aware of US (I'm assuming the amount was in US dollars) prices but I doubt that you would get something that cheap. If it's any help then...
Tecan makes such a device for precisely locating plates on certain racks. Please contact me offline if this is for a Tecan platform, and I'll be glad to...
Hello, We've been looking at different ways to collect DNA samples (buccal or bloodstains) on paper (FTA, 3MM, etc.). For development, we've been punching...

TO the group Many times we are asked what material is best for deep well plates, polypropylene or polystyrene. My question, if chemcial resistance is not a ...
S, If you are using a system with a movable head on a large deck, the error in the precision is most likely due to the head position, not the plate position. ...
