All Glass Filter Holder 47 mm, complete

The Waters All Glass Filter Holder 47 mm is a five-component set of lab equipment that is made of 100% borosilicate glass. This assures resistance to even the most aggressive solvents for solvent filtration using 47mm filters, giving you a wide range of solvents to work with by investing in only one lab equipment. The most chemically-inert glass available, generally used in high precision laboratories to prevent alteration of test results, is used in the manufacturing of the lab equipment.

The All Glass Filter Holder 47 mm is comprised of:

• One-liter 47 mm glass funnel/support assembly that permits filtration of an entire liter at once.

• Support assembly's unique base design with integral vacuum connection prevents contamination of the vacuum line with filtrate.

• One-liter glass funnel is graduated from 300 to 1,000 mL in 50 mL increments.

• 300 mL glass funnel is graduated from 100 to 250 mL in 25 mL increments. The stepped stem fits into standard one-hole stoppers (9mm).

Filtering of samples and solvents is a method of preventative maintenance that decreases lab time and expenses. Filtering provides quick protection for the instruments and column sections by decreasing downtime. A variety of membranes with different solvent and sample compatibilities, as well as a variety of filtering application devices, are among the many filtering products that Waters carries.

Filters should occasionally be modified depending on usage and mobility phase. To replace the filter, no additional tools are needed. After being inserted into the filter, the unique Plastic Tight Male Nut is manually tightened. The tight plastic fitting only needs to be finger tightened in order to hold without flanging.
