Engin, Cc: ccp4bb The Innovaplate SD-2 (also known as the MRC 2 well plate, or MRC 2 Lens Crystallisation Microplate, or Swissci plate) is manufactured exclusively by Swissci (Switzerland) and distributed by several companies, including Hampton Research. The plate is manufactured and available in two different plastics, UVP (UV compatible) or Polystyrene. Hampton Research offers the UVP version. Engin, I have forwarded you message to Paul Reardon (Swissci) and I will be in touch with you directly to help get you running. Regarding your second question, Art Robbins Instruments still offers refurbished Hydras, parts and service. http://www.artrobbins.com/hydra/ Kind Regards, Bob Cudney Hampton Research 34 Journey Aliso Viejo, CA 92656-3317 USA Telephone (949) 425-1321 extension 200 Fax (949) 425-1611 [log in to unmask] www.hamptonresearch.com -----Original Message----- From: CCP4 bulletin board [mailto:[log in to unmask]] On Behalf Of Engin Ozkan Sent: Wednesday, March 10, 2010 9:55 PM To: [log in to unmask] Subject: [ccp4bb] crystallization plates and robotics Hi, everybody, We recently recognized a problem with our Innovaplate SD-2 (a.k.a. MRC 2-Well) plates from Hampton. Our last batch of Innovaplates have an inconsistent well height such that our crystallization robot (a Mosquito) cannot put protein in all the wells. When tested with an older Innovaplate or a hanging drop cover, everything was fine. Is anybody else observing this? I heard that European customers might be getting the same plates from a different source/manufacturing facility. If that is the case, from which company do you buy these plates? Another question is about 96-channel pipetting equipment: For experiments unrelated to crystallography I am in need of getting a 96-channel pipetting machine, such as Rainin's Liquidator. I am also hoping to use this for transferring crystallization screens from blocks into crystallization trays (Our robot sets up only the drops, but does not transfer large volumes of crystallization solutions). Does anybody use the Liquidator for crystallization reagent transfers, and if you do so, would you recommend it? I am open to any brand/model, so all suggestions are welcome.
