Labplas products are made with extruded tubes of virgin low-density polyethylene. All of our sampling bags comply with the applicable regulations of the Food and Drug Administration (21 CFR 177.1520 (c)3.1a, (c)3.2a and 178.2010 and EU No 10/2011 for use in contact with food.
The material's fabrication is done without any deliberate contact with heavy metals and their concentration in the plastic does not exceed 100 ppm which is in compliance with CONEG and RoHS model requirements.
NO, the maximum tolerated temperature is 80°C or 176°F.
Yes, for temperatures of up to 80°C or 176°F. In this case, make sure to use or products line with safety tabs.
Labplas products can tolerate temperatures as low as -100°C or -148°F, therefore liquid nitrogen is not appropriate.
The polymer film permeability (cm2/m2/day/bars) is quite significant; 7 for nitrogen (N2), 20 for Oxygen (O2), 100 for carbondioxide (CO2) and 1 for water vapour (water bath H2O(v)). However, the bags are waterproof.
Labplas offers various neutralizing solutions. However, given the vast amount of products available on the market, which one is recommended? Depending on the surface, the type of cleaning agents and the type of testing (qualitative or quantitative), they are all suitable choices! For further information, please refer to our latest publication under the tab "News - Publication".
YES. Labplas products are sterilized by the extrusion process or by gamma irradiation. The polyethylene tube extrusion process occurs at temperatures of 200°C (400°F). For our surface sampling kits, irradiation is carried out at intensities ranging from 5 - 30 kGy, depending on the product.
