This gives you an idea of the precision. 1/3 is not a scientific format, but a mathematical one, unless for some constraint you know that value is exactly 1/3, then there is no error associated with it.

Re: [ccp4bb] Problem in molecular replacement
In addition to that good suggestion, with a model at such high sequence identity and with reasonable resolution data, it would be a good idea to search for smaller models, like a single dimer or even a monomer, because the assembly may have changed conformation. Another possibility you should consider is that the space group may not be correct. Good luck!

[ccp4bb] rigaku micromax 007 cooling
Dear all, I have a Rigaku MicroMax 007 HF X-ray generator that is cooled by chilled water supplied rather unreliably through the building infrastructure. I was wondering what alternatives exist. Could other MicroMax 007 users share their experiences with alternative cooling solutions with me? Thank you.

Re: [ccp4bb] rigaku micromax 007 cooling
Dear Andreas, we had a similar issue with our MicroMax 007, with a primary water/water chiller (ATC K3) in between the generator and a secondary inhouse water circuit. After a year of reliable service the K3 would shut off occasionally and dump the 007 with a cooling error. We found that the solution to the issue was to place an additional pump directly in front of the K3. The issue being that the latter would temporarily shut off unless provided with a constant water pressure, which the water circuit wasn't giving apparently. This has now been running fine. Another solution would be a water-air chiller to cool your 007, but in our case that was not an option due to building specs. Hope this helps. I'm happy to provide more details if wanted.

Dear Andreas, We have a Hyfra water cooled system (VWK50) on our MicroMax 007, but it is probably over-dimensioned because it is also used by a Xstream equipment, a smaller dedicated cooler to the micromax could be better.

Re: [ccp4bb] rigaku micromax 007 cooling
I would warn you that the K3 and K9 chillers have internal hoses which cannot tollerate water pressure above 125 psi. We had a hose fail from the building chilled loop pressure. So, be careful adding any pressure with a pump before the chiller...and maybe consider one after the chiller to pull the water through. Kris Kris F. Tesh, Ph. D.

Thermo scientific has air/water chillers. Google: thermo scientific neslab merlin recirculating chillers brings up the links. We have one of these cooling an Oxford xcalibur. It supplies circulating cold water under pressure which we hook up where the house chilled water would go on the water/waer heat exchanger.

Re: [ccp4bb] rigaku micromax 007 cooling
Hi Andreas - My 007HF is cooled by a Haskris R050 chiller which I got from Rigaku. This has a refrigeration loop inside it to extract heat from the closed water loop that goes to the generator; the extracted heat can then go to building chilled water, or even an open loop (city cold water, then down the drain) if your building codes allow it. The advantage of this system is that it can handle unreliable chilled water temperature and flow, with allowable source water temperatures as high as 85 F. If your building water is really unreliable, you can even get an air-cooled Haskris - although your room A/C has to be able to handle the heat load in that case. Contact me off-list if you want more information. The system has been really reliable for me. - Matt On 7/24/14 11:53 AM, Andreas Förster wrote: Dear all, I have a Rigaku MicroMax 007 HF X-ray generator that is cooled by chilled water supplied rather unreliably through the building infrastructure.

Re: [ccp4bb] rigaku micromax 007 cooling
Hi Ours is cooled by a Haskris R250, which is sized for an XStream also. While our heat exchangers have had a couple of issues, overall the Haskris heat exchangers have performed quite well. They redesigned ours when they found out about our building chilled water. I'm not affiliated with and heartily recommend them. As for the water itself, I would ***NEVER*** allow building chilled water into the generator. Our water is extremely dirty and the supply is slightly below spec, so we have a pump downstream of the heat exchanger. There are also 2 filters upstream to pull some of the junk out. Lately, startup has required the use of the pump, which I interpret as buildup in the condenser, so that's eventually going to need a cleanout. That was what the redesign was all about. I imagine ours is an extreme case, but the heat exchanger makes up for a variety of ills. Rigaku also recommends a DI filter to keep conductivity low in the water going into the generator, which improves anode lifetime. Building chilled water will never be able to be as low as desired. Besides, facilities people can change things and you'd never know until it's too late...
