Filtry membranowe z estru celulozy - MembraClear

Filtr MembraClear przeznaczony jest do pobierania próbek z azbestem przy zastosowaniu metody filtracji membranowej z kontrastem fazowym. Podczas pobierania próbek izoluje się włókna azbestu z powietrza w celu oznaczenia zawartości.
MembraClear PCM filter is designed for asbestos sampling using the membrane filter method for phase contrast microscopy. Asbestos sampling isolates these fibers from circulating air to determine concentrations.

• Mixed cellulose ester membranes designed for use with the ‘hot block method’
• White with black grid for high contrast during asbestos testing using microscopy
• Becomes transparent with acetone vapor treatment, distinguishing fibers from crystalline artifacts
• 0.8 μm pore size, with three filter diameter options

We offer a wide variety of sterile and non-sterile mixed cellulose ester membranes for various analytical applications.

High-contrast black grid, clear filter background
MembraClear mixed cellulose ester membranes are designed for quick and clear fiber counting. Acetone vapor treatment renders the PCM filter clear, preventing confusion between asbestos fibers and crystalline artifacts. The black grid on the filter’s white surface enhances contrast.

Asbestos testing using the membrane filter method
The membrane filter method is used to assess the risk of potential asbestos contamination. First, sample air is pumped through mixed cellulose ester membranes to extract airborne fibers. The asbestos concentration is analyzed with phase contrast microscopy, and asbestos fibers are analyzed in line with set rules that determine if a space is within airborne exposure limits.
