Graduated Cylinders: Glass or PP, PMP ?

[olderthandirt]

I've been using glass cylinders for measuring, comfortable with them, and I've accepted the looong wait to get the majority of my VG out of em'.

I read recently, somewhere, that VG does not "stick" to polypropylene or polymethylpentene as it does to glass.
Any insights, thoughts or anecdotes regarding this?

surface tension is what you're talking about. its the liquids ability to cling to a surface. you can take a glass and over-fill it with water and see it bow up over the height of the glass.

I use Glass Graduated Cylinders also.

I don't get to hung up if a Small amount of VG is left when I pour it out. It isn't going to throw my Ratios off Dramatically.

I can't tell the Difference between 70%VG:30%PG and 68%VG:32%PG.

Is surface tension the property that accounts for the slow pour of VG from the glass?
Makes sense to a point, one product description for PMP cylinders made mention that the meniscus would be flatter as opposed to that in glass.

Agreed that the amount ultimately remaining in the cylinder isn't really enough to be concerned with zoid, but hey, if VG , I stay as close to 100% as is realistic, really does pour more readily and completely from PP or PMP I'd likely choose one of those materials in the future.

Has anyone here used both glass and poly with VG and noted a difference?
