CELLTREAT
Bottle Top Filter Units
• 4 different capacity units • 0.45µm and 0.22µm pore sizes
• Use with Media/Solution bottles with 45mm diameter neck
STERILE units with polystyrene funnels,
choose PES membrane or Nylon membrane.
NON-STERILE units with polypropylene funnels,
choose Nylon membrane or PTFE membrane.
All RNase, DNase, DNA, Pyrogen Free.

Bottle Top Filter units fit on CELLTREAT's sterile plastic Solution Bottles (CT-229781, CT-229782, CT-229784, and CT-229785) and on all standard GL 45 threaded Glass Media and Vacuum bottles (those with 45mm diameter necks).  These bottle tops fit on standard Corning® brand media bottles (with orange screwcap), Schott Duran (with blue screwcap) and other popular brands.

All sterile units feature an angled hose barb adapter fits 3 size hose diameters and increases unit stability. This angled hose barb with tubing attached is designed to reduce the tipping of units under to hood.

Polyethersulflone (PES) Membrane Units

Nylon Membrane Bottle Top Units

• Hydrophilic nylon membrane has excellent chemical compatibility and does not require pre-wetting
• Available sterile or non-sterile
• Non-Sterile units that have a polypropylene funnel, are autoclavable, and resistant to chemicals
• Nylon membrane is thermostable to 180°C • High strength
• Nylon has Low Hold-up volumes and is Very Retentive
• Nylon binds in removing trace protein, DNA, and RNA • Pyrogen Free
• Ideal for filtering HPLC samples and respective solvents
• Used for filtering radioactive solutions
_____________________________________________

PTFE Membrane Bottle Top Units
• Hydrophobic PTFE membrane is inert to most organic solvents, alkalies, acids, propellents, and cryogenic solutions
• PTFE membrane needs pre-wetting prior to use to open pores. Prewet with methanol, acetone, or with a compatible fluid having a low viscosity (<0.6 centipoise)
• High thermostability to 140°C • Autoclavable
• For alcohol and non-aqueous solutions • Used for gas/air venting • For HPLC samples and ultra-cleaing of non-aqueous or organic solvents

Non-Sterile Polypropylene Bottle Top Filters

• Fits on standard GL 45 threaded glass vacuum bottles
• Excellent chemical resistance offered with polypropylene housing as compared to polystyrene
• High temperature range of 4˚C to 37˚C is suitable for many applications
• Hydrophilic Nylon membrane has excellent chemical compatibility with esters, bases and alcohols. Does not require pre-wetting
• Hydrophobic PTFE membrane has excellent temperature resistance and is useful for clarifying aqueous samples as well as strong acid and alkali solvent filtration
