Good morning,
We have several waste containers for HPLC waste that are directly 'plumbed' to the equipment (see
example).
Because it is a 5 gallon can and we don't pour off into larger drums (for one thing, the weight of the nearly-full container), in the past we've used a hand-operated fuel oil pump; however the gasket wears out quickly and the time to empty the container is significant.
How do you handle this if you don't pour off into a 30- or 55-gallon drum? Is there a pump or other method you use? I am concerned that a
pump used to dispense flammables might not have the right fittings for the container we use. However, if you successfully use this pump with this type of waste receptable please let me know!
Many thanks,
Margaret
