Statement of Purpose

These links and documents contain information about best practices for fluid collections relevant to natural history collections.

Introduction

Importance of stable environment for long-term preservation

Unstable storage environment accelerates deterioration

-Warmer temperatures speed up deterioration processes

-An increase of 10°C doubles chemical reactions

-Extraction of lipids and proteins goes faster

-Cooler temperatures condense lipids and promote paraformaldehyde formation

-Fluctuations in the temperature and humidity of the storage environment stress specimens, containers and their seals. Relative humidity is temperature dependant, and even short exposures to relative humidity over 65% can trigger a mold outbreak.
