HPLC 용매 중에 미세한 입자가 남아 있을 경우 펌프, 시료 주입기 등의 각종 벨브 장치에 이상을 일으키며, 컬럼 앞부분의 필터를 막아 아벽상승을 초래합니다. 또한 용매 중의 기포는 컬럼 앞 부분의 필터를 막아 압력 상승을 초래 Baseline의 불안정을 일으킵니다

Ideal for vacuum filtration of liquids and degassing of HPLC solvents and mobile phases
- Made of 100% borosilicate glass, assures resistance to even the most aggressive solvents.
- One-liter 47 mm glass funnel/support assembly 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 1000 mL in 50 mL increments.
- 300 mL glass funnel is graduated from 100 to 250 mL in 25 mL increments. Stepped stem fits into standard one-hole stoppers (9 mm).
