You should use round bottom flasks in StarFish systems. Placing conical (Erlenmeyer) flasks (or beakers) directly on the base plate is not recommended, as the magnetic stirring will not be as good as with round bottom flasks.
We sell a range of round bottom flasks that can be used with StarFish, but you can use round bottom flasks from the Carousel 6 Plus (or Classic) or from other suppliers too.
StarFish is compatible with round bottom flasks from 5 ml to 500 ml.
Various sizes of tubes and vials may also be used with StarFish.
If you would like well dimensions for any StarFish MonoBlocks/PolyBlocks to check for suitability with your glassware, please feel free to ask us.
