*I need to get with Joe/Mike/Dan to try to remove the plate in the shaker | |||
*If/when that is done, I need to remove the racks (for possible re-use of plate) and then clean out the entire chamber (lots of rust and scale and other nasty things in there) | |||
*We got the instructions manual and it only mentions cleaning the outside and the glass window | |||
*I suppose that a damp towel or paper towel (no detergent) will be ok | |||
*Thanks Joe and Mike for getting out the plate | |||
**The bolts just had surface rust and they recommend using some penetrating oil or anti-seize to make the changing better | |||
*I will run a cloth through there and try to pick up as much as I can | |||
*If needed, I can use some 1% Alconox solution to clean up the tougher stuff, then wipe it dry | |||
*The plate will not be replaced until the very end. We dont know if a new one is needed or if we will recycle the current one | |||
**Either way, new flask mounts will be needed and that would require the plate to be out to install | |||
***We also need some standard allen wrenches 7/32 (as ours are metric) to get it in there properly | |||
*The boxes from the plate have been removed and are sitting on the table out in the chase | |||
**Koch mentioned that they should be saved as someone might want them (Osinski?) | |||
*The plate itself has the 4 mounting holes in the middle and then some smaller ones on the outer border where the boxes were mounted | |||
**Those outer holes were "Jimmy Rigged". I dont know if we can mount flask holders on this plate, but I suppose we can machine it | |||
*The inside has been wiped clean with paper towels and water. | |||
*I am letting it dry out before I turn it on to test the temperature settings | |||
===Temp Tests=== | |||
*Started the incubator's heater at 3:30pm, set it to 37C | |||
**The current reading by the probe is 20C and the display says 24C | |||
*The instructions state that the temperature setting is for degrees above ambient | |||
**Something to look into once it heats up | |||
*So it turns out that it was not heating up and that we needed for the spinning to be on to get the heater going. | |||
**Its been ~5mins since we turned it on and the heat is at ~90% of the set value | |||
*When the temp said 37C, the meter only read ~27C | |||
*Cranking up the temp (maxes out at 60) | |||
*To measure the temp, i tossed the DVM and probe into the incubator and shut the lid | |||
*The probe is sitting on the bottom of the incubator, possibly touching the floor, but most likely not | |||
**I'm trying to measure air temp, and I am assuming the actual temp is a bit higher than what the meter is reading from the air | |||
*Right now the display says 50 and the meter is reading 33-34C | |||
**The built in temp probe for the incubator is located near the heating element (so says the manual) and may not reflect the actual temperature of the samples inside | |||
* I set the temperature to 60 (maxed) and right now the internal temp is 58 and the meter is reading 37 | |||
*When the incubator maxed out at 60.1 the power meter turned itself off. Rather than warm it back up again (since i would need to open the lid to turn the stupid meter back on), I just turned off the incubator to save energy | |||
*Oh, Koch wondered what the HRS setting was. It's Hours you want the thing to run before turning off. Default is run forever! | |||
[[User:Steven J. Koch|Steve Koch]] 01:08, 11 August 2009 (EDT): Great work with the incubator! That is really interesting about the temperature being so far off from the display & good idea to put the whole meter in there. Actually, I have another idea: you could put a big plastic jug full of water in there, and let it incubate for a couple hours. Then you could pull it out and measure its temperature: that would be the ultimate answer. If indeed we need to put it at 60 to achieve 37, that's really important to know...thanks! | |||
