Emptying water jacket
We are trying to remove the Napco 6300 incubator from our lab, but need to remove the water in the water jacket first.
We cannot find any accessories (threaded hoses, siphon primer) to get the water out, or a port at the bottom for gravity draining.
Has anyone had success with this? It seems like it should be so simple, but I can't get a good seal in the threaded water port.
There is no drain at the base or other specific emptying device. This was done to eliminate any possibility of leakage. At the time of its creation, there were other brands on the market with major leakage problems so the Napco design was a response to that situation.
The procedure is:
- Remove the filling cap
- Take a length of tubing slightly longer than the height of the incubator.
- Fill it with water and place your thumbs over the ends.
- Go to the incubator and keeping your thumb over the top end, lower the bnottom end of the tubing through the filling hole. until it touches the bottom of the jacket.
- Lower the other end of the tubing into a recipient, remover your thumb and siphon off the water.
- Tip the incubator when near the end to get the residual water out (do this before bubbles appear!).
Be aware that the water jacket contains about 40 liters (about 10.5 gallons).
I hope that this helps,
