Product Parameters
Glass Filter Membrane
Product Name: Filter Membrane
Product Brand: Labshark
Product Material: Ultra-fine alkali-free glass fiber
Product Application:Glass fiber filter membrane is a high-performance filter medium made of ultrafine alkali-free glass fibers. It is binder-free and chemically inert. It features fast flow rates, high strength, and high filtration efficiency. It can retain submicron particles and withstand temperatures up to 500℃. It is suitable for monitoring TSP and PM10 at high and medium flow rates. It is widely used in ambient air monitoring, water quality analysis, gas analysis, and routine laboratory filtration.
Product Features:① Small membrane pore size and high interception efficiency② Comply with national standards③ High flow rate and low resistance④ Good temperature resistance
Precautions:
Avoid direct contact with the glass fiber filter membrane with your hands. Microfibers may shed and adhere to your hands, causing itching and discomfort.
When used for particle weight concentration determination, strict constant weight pretreatment is required. Ensure a tight seal when installing the filter in the filter holder or filter device to prevent particle bypass.
Use powder-free gloves and tweezers during handling, installation, and storage to prevent contamination and fiber shedding that could affect background readings.
Store properly after opening to avoid contamination, which may affect experimental results.
Excessive exposure requires special first aid measures and medical follow-up.
For your safety and health, please observe required personal protective equipment in the laboratory.
For research purposes only. Not for use as medicine, food, or for household or other purposes.
