WhYOKO CA Series Aluminum Thin-Layer Chromatography (TLC) Storage Cabinet with YJ Organic TLC Plate Storage Box

Overview

The WhYOKO CA Series TLC Storage Cabinet with YJ Organic Storage Box is a purpose-engineered laboratory accessory designed for the standardized handling, thermal conditioning, and inert storage of pre-coated and self-prepared thin-layer chromatography (TLC) plates. Unlike generic storage solutions, this system adheres to pharmacopoeial dimensional specifications (e.g., Chinese Pharmacopoeia ChP, USP , and EP 2.2.27), supporting routine QC/QA workflows in pharmaceutical, natural product, and forensic laboratories where plate integrity, contamination control, and batch traceability are critical. The cabinet operates on a passive mechanical storage principle—no electronics, no moving parts—relying instead on precision-machined aluminum architecture and chemically inert surface treatment to ensure dimensional stability, thermal uniformity during activation, and long-term protection against ambient moisture and particulate exposure.

Key Features

• Two-component modular design: CA-series aluminum storage cabinet (Type I or Type II) + YJ-series sealed organic solvent-resistant storage box—enabling sequential workflow from oven activation to dark, low-humidity plate preservation.
• Aerospace-grade anodized aluminum construction with uniform thermoplastic polymer coating (non-porous, non-shedding), providing exceptional corrosion resistance to alcohols, chlorinated solvents, ethyl acetate, and petroleum ether—while remaining compatible with standard TLC development chambers.
• Thermally stable up to 150 °C for direct co-placement with TLC plates inside forced-air ovens (e.g., Binder FD series, Memmert UF series); eliminates need for transfer between trays and reduces risk of plate chipping or silica gel delamination during thermal activation (105–110 °C, 30 min).
• Optimized internal geometry ensures zero plate-to-plate contact under gravity loading—preventing edge abrasion, layer cracking, or binder migration during stacking or transport.
• YJ organic storage box features gasket-sealed lid with integrated desiccant port (compatible with indicating silica gel or molecular sieve cartridges), enabling controlled RH environments (<30% RH recommended for activated plates).

Sample Compatibility & Compliance

The CA+YJ system accommodates all standard commercial and in-house prepared TLC plates conforming to pharmacopoeial dimensions: 5 × 10 cm, 10 × 10 cm, 10 × 20 cm, and 20 × 20 cm (layer thickness 0.1–0.25 mm). It supports silica gel 60 F₂₅₄, alumina, cellulose, and reversed-phase C18 plates without deformation or adsorbent leaching. While not a regulated analytical instrument per se, the system contributes directly to GLP-compliant documentation by enabling consistent plate handling—critical for audit readiness under FDA 21 CFR Part 11 (when paired with electronic lab notebook entries), ISO/IEC 17025:2017 Clause 7.2.2 (method validation), and ChP General Chapter 0502 (TLC procedures). Units are supplied with material certification (RoHS-compliant polymer coating, aluminum alloy 6061-T6).

Software & Data Management

This is a hardware-only storage solution with no embedded firmware, connectivity, or software interface. However, it integrates seamlessly into digital laboratory ecosystems via manual logbook entries or LIMS-integrated plate tracking protocols. Each CA cabinet bears a laser-engraved serial number and model designation (e.g., “WHY-CA-I-2024-XXXX”), supporting physical asset tagging and inventory reconciliation. Users may assign unique identifiers to individual plate batches stored within the YJ box—facilitating full traceability from activation timestamp to chromatographic run ID when documented alongside analytical data in compliant ELN platforms (e.g., LabArchives, Benchling, or Veeva Vault RIM).

Applications

• Routine QC release testing of herbal extracts, synthetic intermediates, and finished dosage forms per ChP/USP monographs.
• Stability-indicating method development where plate activation consistency directly impacts R_f reproducibility (CV <1.8% across n=12 plates).
• High-throughput preparative TLC workflows requiring rapid plate turnover and minimized handling-induced variability.
• Teaching laboratories requiring durable, reusable, and dimensionally accurate storage for student-manipulated plates.
• Reference standard archiving—activated plates stored >6 months in YJ boxes retain baseline resolution for caffeine, paracetamol, and ibuprofen under nitrogen-purged conditions.

FAQ

Can the CA cabinet be used in vacuum ovens?
No. The thermoplastic coating is rated for atmospheric-pressure dry heat only (≤150 °C). Vacuum or steam environments may cause blistering or adhesion loss.
Is the YJ box suitable for storing plates after derivatization with ninhydrin or anisaldehyde reagents?
Only after complete solvent evaporation and thorough air-drying. Residual reagent vapors may degrade the gasket elastomer over time.
What cleaning agents are approved for routine maintenance?
Deionized water or 70% ethanol wipe-down. Avoid sodium hydroxide >0.1 M, hydrochloric acid >1 M, or acetone-based cleaners.
Does the system meet ISO 9001 requirements for calibration traceability?
As a non-measuring device, it requires no calibration—but dimensional conformity is verified per ISO 286-1 (tolerance class h9) during final QA inspection, with test reports available upon request.
Can two Type I cabinets fit simultaneously inside one YJ box?
Yes—the YJ Organic Storage Box is explicitly engineered to accommodate dual CA-I units side-by-side, maximizing space efficiency in shared fume hood or oven zones.
