15mL Centrifuge Tubes,Polypropylene,Disposable Conical Bottom Screw Cap,Sterile

Simpure Conical Centrifuge Tubes 15mL 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. 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.

Specification:

Features:

1. High retentate recovery of >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. Leak-proof: With longer length screw caps, it is used to prevent sample leakage and it smooth, flat inner surface, no residual solution. 

5. 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.

6. 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.

7. Writing Area: 15mL 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. 

8. Compliance: Manufactured under ISO 9001: 2000 standard and FDA Quality System Regulation in Chapter 1, Title 21, Section 820 of CFR.

9. 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). Also the storage tubes with caps are great for storing seeds, beads, powders, spices, liquids, essential oils, plant culture and other samples.
