Filtration apparatus

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

• Funnel Volume 250 ml
• to be used with Ø 47/50 mm membranes and Ø 40 mm pre-filter
• silicone cap and venting nozzle included in scope of supply
• GV 050A-Types equipped with rapid closure clamp

Amicon® ultra centrifugal filters promote high sample recovery, even in diluted samples, through ultrafiltration and also provide fast sample processing. Particularly suitable for sensitive downstream applications as the centrifugal filters provide the fastest and most efficient concentration. The Ultracel-30 centrifugal filters have a NMWL (Nominal Molecular Weight Limit) of 30 kDa.

Features & Benefits:

• Prevents turning to dryness
• Provides a predictable concentration factor
• No calibration is necessary to run multiple samples in parallel
• Vertical membrane aligned with filtrate instead of vertical for loss constipation, less waste and faster filtration
• 25 to 80 times the concentration in one step
• Wide chemical compatibility, heat-sealed membrane and compatible with pH 1-9
• Maximum sample recovery as Ultracel® low-bund membrane > 90 % recovery
• Centrifuge your valuable sample with security in a robust, slim unit that prevents leakage

Ready-to-use funnels and filters in one. Milliflex® filter units combine a sterile gridded membrane filter with a sterile funnel.

The EZ-Pak® system with the Microfil® filter system contains sterile, ready-to-use funnels. These are in a convenient dispenser with a special filtration support to facilitate processing. Preparatory steps do not have to be observed, as they are not required here. The special "Push-Fit" funnel ensures perfect sealing without clamps.

High sample recovery by ultrafiltration, even in diluted samples, and fast sample processing are offered by Amicon® ultra-centrifugal filters. The centrifugal filters, for fastest and most efficient concentrations, are specially designed for sensitive downstream applications. The Ultracel-10 centrifugal filters have a NMWL (Nominal Molecular Weight Limit) of 10 kDa.

Features & Benefits:

• Prevents rotation to dryness
• Providing a predictable concentration factor
• No calibration necessary if several samples are to be run in parallel
• Vertical membrane, aligned with filtrate
• Less clogging, faster filtration and less waste

• Robust, slim unit that prevents leakage

The Biopak® final filter is a disposable ultrafiltration module that is installed directly at the extraction point of Milli-Q water treatment systems. The filter produces pyrogen and nuclease-free ultrapure water for up to three months. The final filter consists of a white ABS housing and polysulfone hollow fibers.

Features & Advantages:

• Pyrogen-free water (< 0.001 EU/ml)
• RNase-free (< 1 pg/ml) and DNase-free water (< 5 pg/ml)
• Bacteria-free water (< 0.1 CFU/ml)
• Direct installation on all Type I water treatment systems from Merck Millipore
• Maintenance-free

For fast and uncomplicated sterile filtration of aqueous solutions in bottles with narrow or wide threads, the Steritop™ bottle top filter with large filter surface is ideal. Inside the funnel there is a small tab with which you can securely attach a separately available pre-filter during filtration. In order to provide optimum protection against contamination, the thread of the bottle cap is slightly set back.

• Fast flow rates and low protein binding
• Gamma sterilized
• Click-seal closure signals correct closure
• Quick Release: unscrewing the bottle with only a quarter turn
• Easier labeling due to frosted writing surface/bright cap color
