Glass Microfiber Filter 7 cm 1.5 µm PK100

This pack contains one hundred glass microfiber filters each measuring 7 cm in diameter with a 1.5 µm pore size. The binderless borosilicate glass construction suits laboratory air and liquid filtration tasks. Each disc is 0.43 mm thick and rated for a maximum operating temperature of 500 °C.

Grade TSS and binderless material

The TSS grade indicates a specific filtration performance level for total suspended solids. A binderless matrix reduces extractables and ensures the filter does not introduce contaminants into sensitive samples. The borosilicate glass microfiber withstands high temperatures without degrading during hot gravimetric analysis.

Suits gravimetric labs and air sampling

Technicians performing EPA or standard methods gravimetric testing will find the pore size and temperature rating appropriate. Facilities needing sterile membrane filters or larger diameter discs for high-volume filtration should evaluate alternative products. Users requiring chemical resistance beyond borosilicate glass must verify compatibility separately.

Questions about this item

How often will the 1.5 µm glass microfiber filters need replacement during continuous liquid filtration?

Replacement frequency depends on the particulate load and volume processed; each filter is a single-use consumable supplied in a pack of 100.

What is the first limit reached when filtering hot liquids at the maximum operating temperature of 500 °C?

The binderless borosilicate glass microfiber is rated to 500 °C; the practical limit is the filter's pore clogging or mechanical stress before the material degrades.

Does the 0.43 mm thick filter media generate noticeable heat or require extra power when used in an all-day air sampling rig?

The passive filter media adds no heat or power draw; only the sampling pump contributes to operating temperature and energy use.
