Membrane Solutions Conical Centrifuge Tubes 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: 50mL 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 5mL, 2.5mL increments, white writing area resists solvents.

6) Writing Area: 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.

Product Description
Membrane Solutions Lab Supply Syringe Filters PES with extremely high microbial filtration capacity and unique threaded interface design with ISO 9001 certificated.
PES Syringe Filter Diameter: 25mm, 0.22μm pore size can fast sterilization of buffers, culture media or other solutions.
The most commonly types membrane for sterile syringe filters are PES and PES with GF pre-filter. PES features high flow and lowest protein adsorption, which can meet the broadly applications, such as buffer, protein, culture medium, additives and so on. And GF pre-filter has excellent dirt-holding capacity, which makes a syringe filter a much larger throughput for some “hard to filter” sample.

High Water Flow Rates
Polyethersulfone microporous membrane is a hydrophilic membrane with high flow rate, low dissolution, good strength, no adsorption of protein and extract, no pollution to samples.

High Bubble Points
MS filter withstands a maximum case pressure of 10 bar (145 psi) and the solution is 20% faster than comparable products

High Throughput
MS filter have a larger filter surface area increases the flow rate. It also reduces the pressure required to empty the syringe, making the filtration solution easier.
