Dear Colleagues, This fall we will be integrating automated CE analysis into our undergraduate biochemistry curriculum. Our immediate goal is to familiarize...
Dear All, I work in a natural products based pharmaceutical company and have been getting very low yields during my purification runs. Does someone know any...
Kevin, There are two sources local to you in NJ that would be a good point of reference for information on CE. Eutech Scientific- Dr. R. Sahai Phone no...
My laboratory would like to buy a Plaque Picker. I am looking for one which can pick up the whole plaque/agar with a hollow needle. Please share some of your...
Hello to all HTS and Assay Automation people! We've just purchased the new Titertek Multidrop Micro (1ul-50ul) and already encountered a problem with the...
Hi, Have a look at the biopick from Biorobotic. This is a fully automated colony picker but able to use a hollow needle for plaque picking as well. ...
Can anybody offer any advise on the elimination of hanging liquid drops on the end of pipettes after an aspiration/dispensation cycle with liquid handlers?...
Hi Andrey, Although I do not have experience with the new Multidrop Micro, I am quite familiar with Titertek Multidrop dispenser principals. My general steps...
Andry, With our Tecan Genensis, if we get residual drops after pipetting, it's usually an indication of air in the lines. Or it may be a loose connection...
Hi, there are some ways to prevent drops on the end of tips. One way is to work with air gaps. That is useful specially if you work with low volumes. An other...
Although Titertek resells it, I believe that Thermo manufactures the multidrop micro. If the problem were a common one, I would imagine they would have a...
... We deal with this by doing a "touch" after the aspirate or dispense. This is a liquid sensing move with zero movement below the surface and of course...
Hello There, It depends on the liquid handler you use. If if is something like the BioMek FX or MultiMek, you can create a "liquid tip touch" maneuver where...
D Sweeny, There are many variables connected with this problem. It would help the forum if other users knew what brand pipettors you are using, what format...

When sterilizing fixed tips on my Apricot transfer device I have observed that 70% Ethanol washes have little or no effect on E coli. Does anyone have any...
Hi, I don't know what type of liquid handler you are using, but in general a 'traveling air gap' can be used following aspiration to delay reagent from leaking...
You might try Eosin Y, I know it will go into solution in acetone with adequate vortexing, but I don't have a sense if it precipitates out over time or with...
Hollow needles can have very serious cross-contamination issues. What are you trying to accomplish with a hollow needle? Is cross-contamination a potential...
... The quick and simple answer is to use a tip-touch after each aspiration and dispense. I know that this is a standard option on the Velocity11 VPrep and ...
D Sweeny, depending of the liquid handler you use, you may apply different or additional methods. One is to use a tip touch, i.e. the tips move to the border...
At Genetix we use solid pins to pick phage plaques and simply use a thicker pin than we would for picking bacterial colonies. We have data from a customer...
Hello there, I have successfully used a sterilization wash protocol on a Robbins Hydra fixed-tip syringe liquid handler for over 5 years and running. Alcohol...
It wasn't clear to me what type of liquid handler was being referred to here. If there was a previous thread by schwonney concerning the Multidrop, then I...
I'm looking for solutions to integrating a Discovery-1 system from Universal Imaging (Molecular Devices) with a CRS Dimension 5 robotic arm. We purchased the...
To clear up any confusion (or to confuse some more thoroughly), there was a question posed first by keen_ii regarding the MultiDrop Micro and hanging droplets...
The fact that I find this exciting will tempt you to offer me life-style advice, however: I was excited to learn recently how effective it could be to withdraw...
I apologize for the confusion regarding the system I was referring to when talking about hanging drops. The system is a prototype system we are evaluating. The...
