47mm 필터 깔때기,유리

  • 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 1,000 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).

SolVac® Filter Holder

SolVac® Filter Holder

필터홀더

  • Versatile design fits most HPLC bottles, flasks, and containers, and eliminates the added steps of washing flasks and transferring mobile phase solvent from flask to reservoir.
  • Draws directly from HPLC solvent bottle. Less likely to spill aggressive solvents than glass funnels or disposable cups.
  • Durable plastic construction is less likely to break than glass funnels, assemblies, or adapters.
  • Patented magnetic seal is reliable and leak proof. Eliminates thepossibility of membrane shifting or tearing which can occur with aluminum clamps or threaded holders.
  • Reusable, chemically resistant polypropylene construction is resistant to common HPLC mobile
    phase solvents such as methanol, acetonitrile, and tetrahydrofuran.

Nanosep® MF Centrifugal Devices With GHP Membrane

Nanosep® MF Centrifugal Devices With GHP Membrane

원심분리기 디바이스(GHP)

  • Rapid processing of samples. Centrifugal devices are simple to use and save on sample preparation time. Spin multiple samples at once!
  • Universal membrane filter. The GHP hydrophilic polypropylene membrane is ideal for aqueous solutions and offers maximum chemical compatibility for aggressive solvents.
  • GHP membrane is a low protein binding membrane. It removes unwanted particulate from samples with high recovery of critical proteins.
  • Low extractables. Our HPLC-grade centrifugal devices are certified to be low in UV extractables.
  • Low hold-up volume (< 5 μL) makes these devices ideal for expensive samples.
  • High g-force ratings. Can be spun at 14,000 x g for confident rapid sample processing.
  • Leak-free operation. Unique sealing technology assures leak-free operation without the use of
    O-rings or adhesives that can add extractables.
  • Constructed of low binding polypropylene.
  • Fits standard centrifuge rotors that accept 1.5 mL tubes.

AcroPrep™ 24 Filtration System

AcroPrep™ 24 Filtration System

필터시스템

  • Reduces labor time by 20 minutes per carousel over the conventional
    syringe filter technique.
  • No need to use cumbersome, individually wrapped, disposable syringes. Use disposable pipette tips which are less costly, easier to use, and require less bench space.
  • Designed for use with Waters Alliance HPLC systems.
  • Pall’s HPLC certification ensures that analytical results will not be compromised by extractable filter material.
  • No cross-contamination. Each 1.9 mL well is individually sealed, ensuring your sample will accurately dispense into the Waters Alliance sample carousel* with no crosscontamination
    or splashing.
  • Materials of construction are identical to Pall’s Acrodisc® syringe filters; if you are currently using Acrodisc syringe filters, this will reduce the requirements for validation of the AcroPrep 24 filter plates.
  • Can be used with any conventional 12 x 32 mm vials; simply transfer your filtered samples from the Waters Alliance sample carousel to any HPLC sample carousel that houses 12 x 32 mm vials and save
    both time and labor. Can be used to process fewer than 24 samples. Simply label used wells or isolate unused wells with parafilm for application at a later time.
