Centrifugal Filter Devices
Sartorius Air Pressure Controller (APC) for Vivacell Models
Use in combination with Vivacell™ Products to regulate and apply pressure to Vivacell™ units. Can be used with any pressure source.
Cole-Parmer Advantec USY-20 Disposable Ultrafiltration Unit, 200K MWCO, pack of 24
These disposable ultrafiltration units are designed for ease in concentrating, separating, or otherwise purifying small volumes (<2 mL) of liquid samples, on the basis of molecular weight cutoff using positive pressure. The unit is constructed of polypropylene cap, acrylic retentive cell, and filtrate cell. Filter media is polysulfone. To use, simply dispense sample into the retentive cell by pipette, place cap on retentive cell, and inject 10 mL of air with a syringe. Remove cap to stop filtration. Sterilization: 25% ethanol, 5% formalin.
Stellar Scientific EXCELBAND 100 BP 3K DNA 500UL
The DM2300 ExcelBand 100 bp+3K DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct loading on gel. The DM2300 DNA ladder is composed of 12 individual DNA fragments: 3k, 1.5k, 1k, 900, 800, 700, 600, 500, 400, 300, 200 and 100 bp derived from a mixture of PCR products and specifically digested plasmid DNA. This product contains two enhanced bands (1.5 kb and 500 bp) for easy referencing. In addition, two tracking dyes, Xylene cyanol FF and Orange G which mimic the migration of 4,000 bp and 50 bp dsDNA during electrophoresis are also added for real time monitoring.
Electron Microscopy Sciences CytoSep™ Cytology Single Funnel Tubing with Cap
This plastic CytoSep MEGA Funnel provides an easy, efficient and cost effective method of producing high quality thin-layer slide preparations and can be used for preparation of large volume samples. It eliminates the needs for stainless steel clips.
The larger funnel is quick and easy to remove. The large rectangular cell deposition area of 22 x 14.75 mm (325 mm squared) provides for up to 12 times the sample volume (6 ml) of the single Cyto Cytology Funnel. Strategically placed baffles inhibit cell setting which results in uniform cell deposition and excellent quality slide preparations. This MEGA funnels and cap minimize user exposure to pathogens while reducing the risk of specimen cross contamination. Can prepared both air dried and fixed preparations.
