Product Information: Grade 50 Filter Paper, 15 x 23 cm
Manufacturer Part # 1450-916
Description
- Hardened low ash: 0.015% ash maximum
- These filters are treated with a strong acid to remove trace metals and produce high wet strength and chemical resistance
- These are particularly suitable for Büchner filtration where the tough smooth surface of the filter makes it easy to recover precipitates
- The maximum ash content of these grades is intermediate between ashless and qualitative grades
- They are particularly suitable for Büchner filtrations where it is desirable to recover the precipitate from the filter surface after filtration
- Other characteristics include high wet strength and chemical resistance, which are similar to those of the acid-hardened ashless filter papers
- Retention of very fine crystalline precipitates
- The thinnest of all Whatman filter papers
- Slow flow rate
- Hardened and highly glazed surface
- This finish also keeps the paper free from loose surface fibers
- Highly suitable for qualitative or quantitative filtrations requiring vacuum assistance on Büchner or three-piece filter funnels
- Very strong when wet. Will withstand wet handling and precipitate removal by scraping. In the electronics industry, the virtual absence of fiber shedding is utilized in carriers for integrated circuits
- This grade is also available in Smear Tab format for wipe testing (e.g., testing of surfaces for radionuclide contamination)
