Transfer Pipettes DIY

I use a small plastic bottle and a clear plastic straw to make a pipette.

Make a hole in a bottle cap using a hot soldering iron.

Insert the plastic straw in the hole.

Seal the hole in the cap with hot glue.

I prefer to do it from the inside of the cap.

Let the glue cool.

Screw the cap onto the bottle.
Make sure it's screwed tight.
The straw should be the only way for air to get in/out the bottle.
We have made the pipette.

Test the pipette.

Squeeze the bottle slightly with your fingers.

The bottle should return to its normal shape instantly as you release your grip.

Squeeze and hold the bottle.

Dip the straw into the water.

Ease your grip on the bottle to create a vacuum in the bottle that sucks water into the straw.
The water should stay in the straw.

Squeezing the bottle again forces the water out of the straw.

Water leaks from the straw if the cap is screwed loosely or if the hole in the cap is not sealed.
Hold the end of the straw pointing down.
Otherwise water will flow from the straw into the bottle.

Use the pipette to catch and transfer any little creatures and baby fish.
Here I transfer a newborn guppy.
Keep both aquariums close to each other to prevent any accidents.

Place the end of the straw as close to the target as possible.
Release your grip on the bottle.

Pipettes make the transfer safe and do not disturbing anything in the aquarium.

Here you can see the fry in the straw.

Dip the straw in the water.

Squeeze the bottle gently to release your catch.

I am going to transfer it back.

Pipettes are a good tool for aquariums of any size, and the only tool to go with in small aquariums.

Have fun and happy aquariums :)
