OK,
Firstly, what you do depends on what samples you are dealing with. We
decalcify smallish samples of bone about 1x1cm - this can either compact or
trabecular bone.
Here are some of the things I learned..
1. Do not overload the chamber.place samples between the electrodes, and
rather do fewer samples - decal can be very quick if used right.
2. Do not use metal lids on casettes if using them (or any metal clips,
parts etc)
3. If the samples aer heavily mineralised, ie huge pieces of compact bone,
change the fluid when you see that the fizzing around the electrodes has
slowed
4. Rather swich off the unit overnight (with the samples still in) if you
are doing a long decal - then swich on in the day, so that you can monitor
progress.
5. Not all sam[les will decalcify at the same rate - check them all
individually at 4 - 5hr, or in the morning of the next day
5. When decal is finished - rinse samples thoroughly in running tap water
for at LEAST and hour before processing
6. I have decalcified a slice of pig femur about 0.5 cm thick in about 5hrs
hope this helps

The time expended in the process was too long and the tissues had artifacts
when examined on the microscope. We did exactly the same procedure described
in the Sakura brochure.
Do you do something different? How do you verify the process? How long does
it take to get the samples decalcified?
Thanks for your help!

Could you please explain what the problems are. I have had excellent
results
with this system

Hi,
Does anyone out there have experience with the decalcifier System from
Sakura? We have just recived the equipment but we could'nt get the
results
that they describe in the brochure.
