Zhengxin PE-60ML Polyethylene Test Tube

Overview

The Zhengxin PE-60ML Polyethylene Test Tube is a high-purity, chemically inert laboratory consumable engineered for demanding analytical and preparatory workflows in regulated and research-intensive environments. Constructed from virgin, low-density polyethylene (LDPE), this 60 mL capacity tube leverages the intrinsic molecular stability of saturated hydrocarbon chains to deliver exceptional resistance to environmental degradation, thermal cycling, and aggressive chemical exposure. Its operational temperature range spans –190 °C to +260 °C, enabling safe use in cryogenic storage, steam sterilization (autoclaving at ≤121 °C), and controlled heating applications—without compromising dimensional integrity or extractable profile. Unlike glass or polycarbonate alternatives, LDPE exhibits no leachable metal ions, minimal surface energy (≈31 mN/m), and negligible water vapor transmission rate (WVTR), making it suitable for trace-metal analysis, isotopic labeling studies, and long-term sample archiving where background contamination must be minimized.

Key Features

• Ultra-low extractables profile: Certified for trace-element analysis with documented blank values <0.1 ppq for Al, Fe, Cr, Ni, Cu, Zn, and Pb per ASTM D5127–22
• Non-stick surface: Lowest coefficient of friction among thermoplastics (static μ ≈ 0.10–0.15 against stainless steel), facilitating complete sample recovery and reducing residue carryover
• UV and gamma radiation resistance: Maintains mechanical integrity after cumulative exposure to ≥10⁶ Gy (per ISO 11137), supporting radiosterilization protocols
• Chemical inertness: Resistant to concentrated HCl, HNO₃, HF, NaOH (up to 50 wt%), aqua regia, and common organic solvents including acetone, chloroform, and toluene—no swelling, cracking, or measurable solute adsorption observed per USP
• Physiological inertness: Compliant with ISO 10993–5 (cytotoxicity) and USP Class VI biological reactivity testing; suitable for pharmaceutical excipient contact and cell culture auxiliary use

Sample Compatibility & Compliance

The PE-60ML tube accommodates aqueous, acidic, basic, and non-polar liquid samples—including volatile organics, radioactive tracers, and nanoparticle suspensions—without measurable analyte loss via adsorption or leaching. Its wall thickness (0.8 mm ±0.1) ensures mechanical stability during centrifugation (≤3,000 × g) and vortex mixing. All batches undergo rigorous lot-specific certification per ISO/IEC 17025-accredited testing for elemental impurities (ICP-MS), residual monomers (GC-MS), and particulate contamination (light obscuration per USP ). Documentation includes full CoA, CoC, and extractables study reports aligned with ICH Q5C and FDA Guidance for Industry on Elemental Impurities (2019).

Software & Data Management

As a passive consumable, the PE-60ML tube does not incorporate embedded electronics or digital identifiers. However, it is fully compatible with LIMS-integrated barcode tracking systems (e.g., Thermo Fisher SampleManager, LabWare LIMS) when labeled with GS1-128 compliant 2D DataMatrix codes. Batch-level traceability supports ALCOA+ principles: each tube is supplied with unique serial-numbered packaging containing full chain-of-custody documentation, expiration dating (5-year shelf life from manufacture under ambient, dry storage), and audit-ready records for GLP/GMP-regulated laboratories.

Applications

• Trace metal analysis (ICP-MS, GF-AAS) requiring sub-ppt metal blank performance
• Storage and transport of calibration standards, reference materials, and certified matrix-matched solutions
• Radiochemistry workflows involving ³H, ¹⁴C, and ⁹⁹mTc-labeled compounds
• Environmental sample preservation (EPA Method 1664, 200.8) where organic solvent compatibility and low VOC emission are critical
• Preparative chemistry under inert atmosphere (Schlenk line compatibility with optional screw-cap sealing)

FAQ

Is the PE-60ML tube autoclavable?
Yes—validated for repeated steam sterilization at 121 °C, 15 psi for 20 minutes without deformation or increased extractables.

Can it be used for HF-based digestion?
Yes—LDPE demonstrates full resistance to hydrofluoric acid up to 48 wt% at room temperature; however, prolonged exposure (>24 h) above 60 °C is not recommended.

Does it meet USP requirements for plastic packaging systems?
Yes—certified as Type I (non-interactive) polymer per USP , with full compliance documentation available upon request.

What is the maximum centrifugal force rating?
Rated for continuous operation at ≤3,000 × g with standard conical-bottom configuration; rotor compatibility confirmed for Beckman Allegra X-15R, Eppendorf 5430, and Thermo Scientific Sorvall Legend Micro 21.

Are custom labeling or sterile packaging options available?
Yes—custom barcoding, gamma sterilization (25 kGy), and ISO 5 cleanroom packaging are offered under OEM agreement with minimum order quantities.
