Laboratory Sample Storage

UV Resistance of Plastic Lab Containers

If a reagent stored near a window gradually changes color over a week, the cause is often not contamination—it’s UV-induced degradation. In some cases, the container itself becomes brittle after…

Autoclavable vs Non-Autoclavable Containers

If a bottle deforms after a 121°C autoclave cycle, the cap may no longer maintain torque, and sealing performance drops. The next step—storage or transport—introduces micro-leakage that is not immediately…

Glass vs Plastic Laboratory Containers

If a container shatters during cold-room handling, the loss is immediate. If a plastic bottle slowly allows vapor transmission, the loss is gradual—and often harder to detect. In pharmaceutical and…

PET vs HDPE Bottles for Laboratory Use

If a solvent stored in a clear bottle gradually loses volume over a week, the issue is often not evaporation alone—it’s permeability through the container wall. In other cases, a…

Temperature Tolerance of PP Containers

If a tube warps after autoclaving at 121°C, the cap torque drops and sealing fails. The next run looks fine—until micro-leakage introduces contamination. At the other extreme, a bottle that…

Advantages of Polypropylene Containers in Labs

If a container cracks during -80°C storage due to uneven wall thickness or material brittleness, the result is not just sample loss—it can contaminate an entire freezer system and compromise…
