Flask Tray P6-250

Overview

The Flask Tray P6-250 is a precision-engineered laboratory accessory designed to securely hold and organize standard Erlenmeyer flasks, volumetric flasks, and conical culture vessels during storage, transport, or incubation workflows. Constructed from high-grade, autoclavable polypropylene, the tray features a rigid, chemically resistant architecture optimized for repeated use in demanding wet-lab environments—including microbiology labs, bioprocessing facilities, and quality control laboratories. Its modular design adheres to standard benchtop and incubator footprint constraints (e.g., compatible with 250 mm × 250 mm shelf spacing), enabling seamless integration into ISO 15189-accredited workflows and GLP-compliant sample handling protocols. Unlike generic plastic trays, the P6-250 incorporates molded retention geometry—each well is dimensionally calibrated to cradle 250 mL flasks with ±0.5 mm radial tolerance—minimizing lateral movement and preventing cap loosening during orbital shaking or stack-based storage.

Key Features

• Optimized well geometry for stable retention of 250 mL Erlenmeyer flasks (e.g., Pyrex® 7740, Kimax® 3330) without additional clamping or foam inserts
• Chemical resistance validated against common lab solvents including 70% ethanol, 10% sodium hypochlorite, and 1 M HCl (per ASTM D543-20)
• Autoclavable at 121 °C, 15 psi for ≥20 cycles without warping or dimensional drift (tested per ISO 17664-1)
• Stackable design with interlocking alignment lugs—up to six trays may be safely stacked under static load conditions (per EN 17277:2020)
• Non-slip base with micro-textured surface pattern (Ra ≈ 3.2 µm) to prevent sliding on stainless-steel or laminated work surfaces
• Integrated alphanumeric labeling zones (laser-etchable surface) for traceable asset management in FDA 21 CFR Part 11–aligned environments

Sample Compatibility & Compliance

The P6-250 supports flasks conforming to ISO 4788 (volumetric flasks) and DIN 12331 (Erlenmeyer flasks), with nominal neck diameters of 32–38 mm and base diameters of 85–92 mm. It is routinely deployed in applications requiring adherence to USP Analytical Instrument Qualification (AIQ) guidelines for ancillary equipment—particularly where tray-induced vibration damping or thermal mass uniformity impacts incubation reproducibility. The material complies with EU Regulation (EC) No 1935/2004 for food-contact materials and has been certified non-cytotoxic per ISO 10993-5. Documentation includes full Declaration of Conformity (DoC), material safety data sheet (MSDS), and batch-specific validation reports upon request.

Software & Data Management

While the P6-250 is a passive hardware component, its physical attributes support digital lab infrastructure. The etch-ready surface enables direct integration with LIMS barcode labeling systems (e.g., Thermo Fisher SampleManager, LabVantage). When used in automated incubator systems (e.g., Binder KBWF series), the tray’s consistent height (28.5 mm ± 0.3 mm) ensures reliable robotic gripper engagement and vision-system recognition. Traceability is enhanced through optional QR code engraving—compatible with audit-trail generation in electronic lab notebooks (ELNs) compliant with ALCOA+ principles.

Applications

• Standardized flask staging prior to sterilization in gravity-displacement or pre-vacuum autoclaves
• Controlled-temperature incubation of microbial cultures (e.g., ASTM D5428-22 for waterborne pathogen assays)
• High-throughput media preparation workflows in pharmaceutical QC labs operating under ICH Q5C stability guidelines
• Transport of filled flasks between analytical suites while maintaining orientation integrity during cart-based transit
• Support platform for flask-mounted pH or DO probes during long-term fermentation monitoring

FAQ

Is the P6-250 compatible with shaker-incubators?
Yes—the tray’s low center of gravity and anti-slip base maintain positional stability at orbital speeds up to 150 rpm (amplitude 25 mm), as verified per DIN EN 60068-2-6.
Can it be used for sterile filtration setups?
It serves as a validated support platform for vacuum filtration manifolds when paired with filter flasks meeting ISO 4792 specifications; however, direct contact with aggressive filtrates (e.g., concentrated TCA) requires prior compatibility testing.
Does the tray meet cleanroom classification requirements?
The polypropylene formulation yields ≤10 particles ≥0.5 µm per cubic foot under ISO Class 5 conditions after Class 100 cleanroom washing (per ISO 14644-1); particle shedding data available in Certificate of Analysis.
What documentation accompanies each shipment?
Each unit ships with a Unique Identification Number (UIN), batch-specific CoA, and compliance summary referencing ISO, ASTM, and EU regulatory frameworks.
