Lab Chat usually deals in HPLC, reference standards and testing methods. This time, it was BAC water.
A member posted a vial of vendor BAC and asked:
“Is this normal?”
Then:
“I mean, they look like bubbles right? Or am I 100% wrong?”
Amino Metrics was initially reassuring:
“Bubbles are friends.”
And he went on to explain that during manufacturing and purification, while collecting fractions, it’s a visual sign of a highly concentrated protein
The member then produced more examples.
“These are just plain bacwater by the way.”
Amino Metrics suggestion was that alcohol can act as an anti foam.
This was followed by the rather important correction:
*“VENDOR BACWATER.”
The discussion changed direction fairly quickly.
One member looked at the visible material in the vial and said:
“The aggregate/floaters alone screams no for me. I wouldn’t use a reconstituted vial that looked like that let alone plain BAC.”
Then came:
“Ganges River Bacwater. It’s special.”
Anela was even less diplomatic:
“That’s not bac water. That’s bath water.”
And finally someone else piped up with:
“BACKroom water!”
So, in the space of one Lab Chat discussion, we went from “Bubbles are friends” to BACKroom water.
The sensible bit: bubbles on their own prove very little. Visible floaters or cloudiness are another matter, although nobody can identify what they are from a Telegram video.
But as BAC-water reviews go, bath water, Ganges River and worm probably aren’t going on the vendor’s promotional material.
