buchner funnel -swim got a large plastic salt shaker from XXX kitchens cut the bottom out inverted it and glued it inside a plastic funnel, coffee filter papers are just cut in a circle to fit and it works as good as swims real buchner funnel
buchner flask - swim uses 500ml polski orgorki gerkin jar with 2 holes drilled in the lid one for the funnel to be glued into, the other for the vacuum line,
vac pump is a 12 volt tyre compresser $15 with a 20 ml syringe minus plunger glued with arldite onto the air inlet plastic hose is pushed over the syringe
sep funnel--get a 50 ml syringe minus plunger cut the finger placement tabs off just enought to leave a flange then drill out a gatorade sized lid so the syringe fits firmly, glue with arldite and screw the lid back on the bottle and you have a bottle with a syringe poking out the top. the syringe was used just because its hard to seperate when you cant see the layers through the neck of a plastic bottle it also reduces the neck size and cutting down waste. syringes come with pastic caps for when you are shaking /swirling and use your finger as the stop cock gloves are advisable .a small hole is drilled in the bottom of the bottle to allow air in and this is taped over with electrical tape or your finger when shaking
you can make do with rubber stoppers from the home brew shop i have heard about a friend using rubber door stoppers
swim still prefers his sep funnel to a glass one as he tends to drop them all the time
im sure ive seen a bottle of port at the bottle shop that was about 750ml and almost round perhaps that would do
swim hasnt had much luck ,making a condenser that was any good his most succsesfull one only for distill not reflux was made from a 2lt coke bottle and a piece of hard clear plastic (was for storing colored pipe cleaners)tube that was pushed through the neck of the bottle and out of a hole that was melted in the bottom the ends were sikaflexed in to prevent leaking and a hole was cut up the top of the coke bottle so you could fill the unit up with ice it worked ok but was bulky and required lots of ice
