LabEXACT 12K883 Filter Membrane

The LabEXACT 12K883 is a binderless borosilicate glass microfiber filter membrane designed for laboratory filtration tasks. It suits technicians who need consistent pore structure for particle retention or air monitoring. Each disc measures 11 cm in diameter with a nominal pore size of 1.2 µm. The product is supplied in a pack of 100 pieces.

Sustained thermal and flow performance

The membrane withstands a maximum operating temperature of 500 degrees Celsius without binder degradation. Its 0.28 mm thickness provides mechanical stability during prolonged vacuum or pressure filtration cycles. Grade C glass microfiber construction maintains consistent flow rates when processing liquids or air over extended periods. The binderless design minimises extractables during long-duration hot filtration.

Application limits of glass microfiber media

The 1.2 µm pore rating defines the lower particle size retained under standard test conditions. Chemical compatibility is limited to fluids that do not attack borosilicate glass at elevated temperatures. The 11 cm diameter restricts use to filter holders or funnels that accept this specific disc size. Package quantity of 100 sets a minimum lot size for procurement planning.

Questions about this item

Does the 1.2 um pore size let hot exhaust pass through the 11 cm discs without clogging during a full day of testing?

The binderless borosilicate glass microfiber handles 500 degrees C, so continuous hot air or liquid flow through the 1.2 um pores will not degrade the 0.28 mm thick membrane.

What holder or funnel fits the 11 cm diameter so the 100 filters seal properly for leakage checks?

Any standard 11 cm funnel or filter holder with a flat sealing surface will clamp the 0.28 mm thick discs; the bore size matches common lab hardware.

Will the Grade C glass microfiber media withstand the solvents used in older analysers that I still run?

Borosilicate glass microfiber resists most laboratory solvents and the binderless construction prevents media shedding into legacy fluid paths.
