Filtration apparatus

The Stericup® vacuum filtration system combines a filtrate collection bottle with a Steritop™ filter unit. The stability of the unit during filtration is improved by the conical shape of the collection bottle. This makes handling much easier. Even for use under laminar flow conditions the slim, compact shape is qualified. Stacking the closed bottles on top of each other is feasible, thanks to the slightly curved bottom.

Features & Advantages:

• Filtration and storage from 150 ml to 1000 ml possible

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

Durapore® PVDF membranes are characterized by high throughput and high flow rate. To maximize recovery and minimize interaction with your sample, the membrane has very low protein binding.

Features & Benefits:

• Chemical compatibility
• Automation compatible
• Suitable for: Receptor/Ligand Binding Assay, Protein Kinase/Phosphatase Precipitation Assays, Bead-Based Assay

The Stericup® E and Steritop® E sterile vacuum systems are the latest addition to the Stericup® Quick Release family and reduce plastic and packaging by up to 69% by saving the filter funnel. The funnel-less filter products are suitable for use in sterile vacuum filtration of aqueous solutions such as media, tissue culture reagents and buffers.

• Fast flow rates and low protein binding
• Quick Release: unscrewing the bottle with only a quarter turn
• Easy labeling due to frosted writing surface/bright cap color
• Fits to all commercially available media bottles/sterile glass bottles with 38 mm/45 mm thread
• Gamma sterilized

Ideal for biological and pharmaceutical sterile filtration. PES membrane features low protein binding, low level of extractables and a high flow rate. Now available in three pore sizes: The best filter units with 0.20µm and 0.45µm pore size and new to the protection of valuable cell cultures from mycoplasma with 0.10µm pore size. Filter top and filtrate bottle are graduated. Blue color-coded collar with cellulosic vent plug side arm and quick-disconnect tubing adapter. Leakproof, sterile screw closure included for storage of sterile filtrate. Sterile, single packed. Certificate of Quality included in each full case. Lot number, catalogue number, membrane type, pore size and expiration date are printed on filter units, bottle tops and receivers for easy identification and lot traceability.

The Millipore glass filter holder was developed especially for the filtration of various liquids. However, the filter can also be used for other purposes such as HPLC solvent production. The vacuum connection is integrated on the filter holder base and the piston cap, above the filtrate outlet level. This prevents the filtrate from accidentally entering the vacuum tubes.

For cell culture, Greiner Bio-One offers standard and filter cap cell culture flasks with growth areas of four different sizes. Suspension culture flasks complete the range in another sizes.They are made of high-grade polystyrene. The special design of our cell culture flasks makes it possible to efficiently reach the cell lawn with a cell scraper, whilst still providing optimal access with a pipette. The special neck
design reduces the risk of wetting the inside of the cap with medium, thus providing additional protection against contamination. The stacking rim on the top of the flasks ensures firm standing and easy stackability in the incubator.

Properties:

• Improved cell adhesion through physical surface treatment
• Cell culture flasks with filter screw cap
• Canted neck
• Graduation on both sides
• Sterile and user-friendly packaging
• 25 cm², 75 cm² and 175 cm² growth areas
• High and flat design of the 175 cm² cell culture flask for variability of media volume

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-50 centrifugal filters have a NMWL (Nominal Molecular Weight Limit) of 50 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

Used for large volumes of aqueous samples. Presterilized. Contains a nylon membrane which is inherently hydrophilic, has low extractables, is bio-safe and has excellent flow rates. A glass microfibre prefilter ensures a long working life for the main filter and allows the easy filtration of large volumes and difficult samples.

• Connectors: stepped barb (SB) and female national pipe thread (FNPT)
• Filter: GMF/Nylon
