What label layout helps most on a crowded research shelf?

Shared shelves fail when labels look identical at a glance. Worth discussing (research packaging only) • Lot text large enough to read without removing the vial • Consistent placement of variant (for example mass) • Contrast that still works under cool white bench lighting • Whether a second small lot sticker on the cap helps or clutters Reply with what your lab actually mis-picks most often — name vs size vs lot — so feedback stays concrete. — Dane
