Choosing the appropriate plastic reagent bottle is crucial in the laboratory. Let's explore two common materials - HDPE and PP: their respective advantages and applicable scenarios.
Material properties:
HDPE (High Density Polyethylene): This material has a brittleness temperature of -100 ℃, making it excellent when stored at low temperatures, such as in Buffer buffer solutions at 2-8 ℃ and enzyme reagent bottles at -20 ℃.
PP (polypropylene): The brittleness temperature of PP is 0 ℃, which is more suitable for products that require high-temperature storage.
Transparency:
The transparency of PP is better than that of HDPE, which makes PP clearer when observing the state of the reagent.
Performance comparison:
PP has strong impact resistance, and its plastic products usually have a longer service life than HDPE.
Although HDPE has better low-temperature resistance, its toughness may not be as good as PP.
Choose appropriate plastic reagent bottle materials to ensure safe storage and service life of the reagents.
