I remember how at the University at the first laboratory work I was almost exposed to all harmful fumes. The teacher made me write an entire essay on safety at work. I turned to Paperial.com for writing a quality essay. But since then, there have been no such incidents. Therefore, carefully read the safety precautions and the most important advice: to improve how well fumes are taken up and away, put your reactions or equipment as far back in the fume hood as you possibly can.

Hello, Debra -

Apparently the company Education Insights sells the GeoSafari Talking Microscope.

If you have not already done so, I suggest you contact Education Insights Customer Service and ask about the availability of the slides you need.

You can find the Customer Service toll free phone number and email address here:

These equipments use a sbc492 by Aaeon motherboard, and usually they shows a message like "Cmos battery Low".These motherboards use an RTC M48T86PCI with a internal lithyum battery, and just replace that component.Other problems may occur, like damaged slots, and or oxidation, but generally the 486 architecture is a huge way to work,Only clean change the memory(dimm 128 x 100mh)and enjoy.A simple way is a replacement with a new one by Intel, still easy to find in some inventorys, i have many in USA who can suply.

hope to solved

Error 3 is a Door lock error and has nothing to do with the water sensor. Tighten the door down snuggly, but don't over-tighten. If it still doesn't work it may need a door rebuild or switch replacement. Call for service if it doesn't restart.

Error 2 on this model indicates that the imbalance sensor is tripped. If you run the unit with an empty rotor and it does not error, then it simply means that your load was imbalanced. Make sure to put vials into the unit opposite each other, as below.

If it displays "Error 2" with an empty rotor and you did not notice a vibration, then the imbalance sensor is broken and must be replaced. Do not attempt to run the centrifuge without the imbalance sensor, as serious injury may result.

I repair these machines, but you would have to ship it to me in Ohio, which would probably be very expensive.

Here is a rotor balance chart:
