Laboratory Paraffin Sealing Film

1. Transparent, flexible, thermoplastic, high-performance waterproof material.

2. Colorless, odorless, tasteless, does not contain organic fluorine.

3. Thickness 0.125μm.

4. 3-5 times, stretching horizontally and vertically.

5. The range of use of the environment is 20 ° - 40 °, it is best to use the environment of 36 °, (close to human body temperature), after 58 ° C, the performance begins to decline sharply (barely function), up to 100 ° C and more gradually melts into colloid.

1. Oxygen permeability: E. coli four and a half hours of culture to measure od600 repeated experiments in three groups, the bacterial density is very high, the bacterial liquid is diluted 7 times the test od value * 7, to come to the final od value, the United States product od value of 1.55, 1.47, 1.47.

2. Deep-freeze storage: -80℃ frozen for 15 days without any deviation or rupture.

3. Permeability: 150 cc/m2/24 hours at 73°F and 50% humidity.

4. Oxide: 4,400 cc/m2/24 hrs at 73°F and 50% RH. Note: Permeability coefficients were determined at 0°C and 760 mm Hg.

5. Water Vapor: Flat: 88 g/m2/24 hrs at 100°F and 90% R.H. vs. Desiccant (Moisture Absorber)

6. Folding: Due to the inherent low permeability and low sensitivity of the material to water vapor, they differ fundamentally in humidity compared to oxygen or carbon dioxide permeability.

7. Action of common reagents: Not destroyed in liquid nitrogen; Concentrated hydrochloric acid (12N), diluted to (5N), no visible effect after 24 hours; Concentrated sulfuric acid (36N), diluted to (5N), no visible effect after 24 hours; Concentrated nitric acid (22%), no visible effect after 24 hours; Concentrated sodium hydroxide (28%), no visible effect after 24 hours; Potassium permanganate 5%, non-permanent, no visible effect in brown color for 18 hours without visible effect; iodine solution 0.1N: 18 hours in brown color without visible effect.
