OCR exam board Biology PAG 4 Effect of substrate conc on catalase

Has anyone set this practical up using 50cm3 conical flasks as instructed in the PAG instructions?
I am looking to put together a class set of equipment to carry this practical out - we only have a handful of small conical flasks and no bungs to fit. But not sure I would be able to sort out delivery tubes to fit.
Also wondered if it could just be scaled up to use equipment we have - 250cm3 flasks.

What do other people do?
 
Same as LyndaR - the sheet instructs them to put 100cm3 of the H2O2 solution into a 250 conical.

I have to borrow all the delivery tubing stuff off our chemistry department.

@Lisa J Did you know that there is a prefix dropdown to specify the board which will save you time. You can still add it by editing your first post:
