Membrane Solutions Brand: Membrane Solutions founded in 2006. MS@ have devoted continuous efforts to bring about lab filtration solutions to all humankind with high-tech membrane technologies. Who we are? Membrane Solutions is a manufacturer and modifier of microporous menbranes, and a manufacturer of microfiltration devices. Membrane Solutions develops and produces products for Laboratory, Process and Municipal Applications. What we do? Membrane Solutions product are manufactured under ISO9001, and in a certified clean room environment using the latest manufacturing technologies, strict QC and QA principles conducted throughout. Rich experience has been accumulated by years of filter developing. Our values: Membrane Solutions LLC knows how to provide and help scientists to seclect the RIGHT membrane filter, with MS lab filtration products, scienctists are sure going to have the accurate testing results effeciently. Membrane Solutions Conical Centrifuge Tubes 15mL/50mL Centrifuge Tubes are designed for in vitro diagnostic use and intended for concentrating serum, urine, cerebrospinal fluid and other body fluid and other body fluids prior to analysis. Made from high-purity resins and molded using state-of-the-art processes; safe alternative to glass without sacrificing accuracy. Filter device is made from copolymer styrene/butadiene, and the membrane is made from low binding regenerated cellulose, and the filtrate tube is made from polypropylene. Features: 1) High Retentate Recovery: >90%, high recovery regenerated cellulose membrane in a range of molecular weight cut-offs. Hydrophobic, biologically inert surface for good cell or protein recovery. 2) High Quanlity Material: 15mL conical centrifuge tubes with High purity PP Material and Max.RCF: 9,400, it can Autoclavable at 121℃ and freezable to -80℃ , stable from -80°C to +121°C (-112°F to +250°F). [PP = polypropylene, PET = polyethylene terephthalate, RCF = relative centrifugal force (x g).] 3) Lake Proof: 15mL centrifuge tubes have longer length screw caps, which is used to prevent sample leakage and it smooth, flat inner surface, no residual solution. Blue plug-seal closure features double-start thread design for an exceptionally tight seal. 4) EO Sterilized: Centrifuge tubes 15mL is EO sterilized. Nonpyrogenic, endotoxin tested (0.5 EU/mL), DNase/RNase free. Each individual lot is certified for quality and purity. 5) Easy Read: Printed with evenly spaced black graduations to enhance readability without losing precision. Plastic centrifuge tubes easy-to-read black graduations are accurate to ±2%, start at 2mL, 1mL increments, white writing area resists solvents. 6) Writing Area: 15mL/50mL conical tubes with a large unerasable frosting white printed writing area provide easy and legible mark. Large white marking area makes labeling samples easy. Both the graduations and writing areas are chloroform-resistant. 7) Application: Conical Centrifuge Tubes are ideal for cell centrifugation; pelleting; separation by density gradients. Suitable for molecular biology applications including concentrating bacteria for DNA isolation, purification and precipitation of nucleic acids; sample storage (ambient temperature to -80°C); and centrifugation of precipitates. Resistant to alcohols and mild organic solvents (not recommended for extraction procedures). 8) Compliance: Manufactured under ISO 9001: 2000 standard and FDA Quality System Regulation in Chapter 1, Title 21, Section 820 of CFR. 15mL Centrifuge Tube Specifications:Part No.LBCT150SVolume(ml)15mlMaterialPolypropyleneFeatureConical, GraduatedPackaging50pcs/pkSterileYes 50mL Centrifuge Tube Specifications:Part No.LBCT500SVolume(ml):50mlMaterial:PolypropyleneFeature:Conical(graduation)Packaging:25pcs/pkSterile:Yes Package Included:15mL Centrifuge Tubes50pcs Conical centrifuge tubes 15mL or 100pcs Conical centrifuge tubes 15mL or 300pcs Conical centrifuge tubes 15mL or 500pcs Conical centrifuge tubes 15mL 50mL Cenrifuge Tubes25pcs Conical centrifuge tubes 50mL or 50pcs Conical centrifuge tubes 50mL or 200pcs Conical centrifuge tubes 50mL or 500pcs Conical centrifuge tubes 50mL Please according to your need to select the right one pack for you!!!
