What sort of scales are you using? Do you need proper pharmacy scales or will 0.01g accurate ordinary ones do?

Yes, used this method. Weighed bottles at first use (snap top/metal seal removed) and wrote this as start weight on box/in DD register (as double check). Bottle weiged at day end to checks grams lost (total MLS used) to check against register. Did it daily for accuracy as any longer period between checks was a pain to find any 'misses'!

RCVS inspection fully approved of this method as bottle not compromised by content withdrawals to check remaining volume and was quite accurate (can never be quite 100% unless using hub-free needles...).

*Edited* as you are calculating the difference in weight (equivalent to MLS used) in the bottle, the difference in bottle weight between bottles is irrelevant You just need a starting point for each bottle!
