Syringe Filters, PTFE
Recommended for HPLC and GC samples, sterilisation and clarification of most solvents and filtration of gases and for air ventingPolytetrafluorethylene (PTFE, Teflon) membrane, hydrophobicHigh chemical resistance to most solvents and acidsExcellent for the sterilisation and clarification of most solvents (such as acetone, dimethyl formamide or DMSO), and of very aggressive or acidic solutionsFree from wetting agentsThey must be pre-wetted with a polar solvent such as ethanol or isopropanol before filtering aqueous samplesHousing material: PolypropyleneFitting inlet: Female Luer-LockFitting outlet: Male Luer-Slip
Syringe filters, sterile
Applications: Prefiltration and clarification of highly viscous solutions and the removal of large particles from suspensions. Use as a prefilter, with glass fiber membrane 25 mm housing diameter and with additional 0.2 µm CA-membrane.
Syringeless filter system Claristep®
Sartorius has developed a easy-to-use and straightforward filtration setup. The manually operated Claristep® Filtration System offers a way for clarifying your samples prior to analysis.Up to 8 samples are processed simultaneouslyNo syringe requiredNo need for a vacuum source or a power supplyFor low sample volumes ranging from 60 to 600 µlHold-up volume < 30 µlSuitable for all 12 x 32 mm test tubesScope of supply: Claristep® Station consisting of a base, a lid and an exchangeable tray
Syringeless filters Mini-UniPrep™
The Whatman Mini-UniPrep™ filter provides a quick and easy means of removing particles from HPLC samples. In comparison to other methods the amount of time required for sample preparation is reduced to one third. Mini-Uni-Prep™ is a ready-to-use filter unit consisting of a 0.4ml chamber and a plunger. The plunger contains a filtration membrane at one end and a cap with septum at the other. The plunger is pressed through the sample in the chamber. The pressure generated forces the filtrate into the plunger reservoir, with air escaping through the vent hole until the locking mechanism engages to form an airtight seal. The unit can now be placed in any autosampler and the sample analysed.
Syringeless filters SEPARA
SEPARA integrates in one single device auto-sampler vial, filtration membrane, plunger, and cap/septa. The single step filtering process is efficient and saves time. Fast and simple to use. Reducing sample loss. After filtration the sample is ready to use in most standard autosampler. The pre-slit cap ensures easy and clean transfer of sample. 5 different septa material, PP vial with Ø 12 x 33 mm, Filtering capacity 0.48 ml, dead volume <30 µl, maximum operating temperature 50 °C
Syringeless filters, amber Mini-UniPrep™
Amber colorant prevents photo degradation of light sensitive samples. Same colorant used in pharmaceutical containers designed to meet USP specifications for light resistance. Translucent amber chamber and plunger enable easy visual inspection
Syringeless filters, Autovial™
Provides a single disposable, manual pressure filtration system which is fast and easy to use in sample preparation.Built-in pre-filter for 'difficult' samplesMinimal wasteComprise a graduated, medical grade PP barrel, maximum capacity 12ml with 3cm2 filter at the base, luer slip outlet and plunger. Non-sterile
Syringeless filters, slit septa Mini-UniPrep™
Slit septum cap enables Mini-UniPrep use with current robotics on HPLC instruments for high throughput automationDurable yet flexible slit septum cap has been specially designed for instruments with sensitive sampling needs. Sample evaporation is minimal.
Syringeless filters, UniPrep™
Comprise a 5ml capacity, medical grade polypropylene test tube which initially holds the sample, and hollow plunger incorporating a filter at the tip. In use the sample is manually pressure filtered into the plunger which then acts as a storage vial for the filtered sample. The plunger has a removable cap. Non-sterile.
Ventilation filter Sartovent®, PP
The filter is suitable for food products and it reliably retains particles and microbes reliably. It can be steam sterilized or autoclaved separately. The air inlet and outlet openings are configured to ensure optimum flow. The integrated splash guard prevents premature blockage of the membrane.DIN 11.851Retention rating 0,2 µm, nominalHeight 80 mmOuter diameter 110 mm
