Hi Mate, I'm assuming you are talking about syphoning into bottles.. are you racking your beer at all ? If you rack your beer into another fermenter and let it sit a few days b4 you bottle it you remove more of the sedement, and leave the cake behind at the bottom.
if your not racking your beer, you could try to buy a sediment trap for the inside of your fermenter tap and fill your bottles using the keg tap instead of a syphon, if you must syphon use a (steralized) pole/rod/broomstick/whatever and attatch the syphon hose to it, but not all the way to the end of the hose, that way when you stick the rod/broomstick in the beer to bootle you will only syphon the beer, not the sediment. But in all seriousness, i'd do some research into "racking" it produces a much nicer clearer,cleaner beer.
All the best
