Overview
The TB-2 TLC Plate Storage Cabinet & Adjustable Shelf Rack is a purpose-engineered auxiliary system designed for laboratories utilizing thin-layer chromatography (TLC) as a core analytical technique. Unlike standalone scanning instruments, the TB-2 functions as a critical workflow-integrated hardware platform supporting plate handling, conditioning, and archival integrity across all stages of TLC analysis—from post-development drying and solvent evaporation to pre-scanning stabilization and long-term storage. Its mechanical architecture adheres to ISO 17025-aligned laboratory infrastructure standards, emphasizing dimensional stability, environmental isolation, and operator ergonomics. The cabinet integrates seamlessly with KEZHE’s family of TLC scanners (e.g., CS-9301, CS-9501), ensuring consistent plate positioning and minimizing alignment-induced measurement variance during densitometric quantification.
Key Features
- Modular dual-function design: Combines a ventilated drying/hot-air curing chamber (with optional PTC heater module) and a vibration-damped storage cabinet in a single footprint.
- Precision-adjustable shelf rack: Each stainless steel shelf features micrometer-calibrated lateral width adjustment (50–220 mm range) and bubble-level-indicated horizontal leveling (±0.1° tolerance), ensuring flatness-critical plate orientation for reproducible scanner calibration.
- UV- and solvent-resistant construction: Anodized 6063-T5 aluminum frame, 8-mm tempered glass viewing doors with magnetic edge seals, and non-outgassing silicone gaskets prevent cross-contamination and degradation of sensitive stationary phases (e.g., silica gel F254, RP-18W).
- Plate size adaptability: Accommodates standard TLC plates from 50 × 50 mm (micro TLC) up to 200 × 200 mm (preparative scale), with integrated anti-slip rubberized shelf liners and removable edge guides for secure vertical stacking.
- Integrated airflow management: Dual passive ventilation grilles (top exhaust, bottom intake) with optional HEPA-filtered recirculation mode support controlled solvent vapor dissipation—critical when handling chloroform-, benzene-, or ethyl acetate-based mobile phases.
Sample Compatibility & Compliance
The TB-2 is validated for use with all commercially available TLC plates—including silica gel, alumina, cellulose, polyamide, and reversed-phase variants—regardless of binder type (calcium sulfate, gypsum, or polymer-based). Its interior geometry conforms to ASTM D1193 Type IV water purity handling guidelines for ambient storage conditions, and its sealed enclosure meets ICH Q5C temperature/humidity stability requirements for chromatographic plate archiving. All materials comply with USP extractables testing protocols; no leachable organics or metal ions are detected under simulated 72-hour static exposure at 40°C/75% RH. The unit supports GLP-compliant documentation workflows via optional RFID-tagged shelf labels (sold separately) compatible with LIMS integration.
Software & Data Management
While the TB-2 is a hardware-only accessory, it interfaces directly with KEZHE’s VisionTLC Suite v4.2+ software through synchronized barcode/QR code plate logging. When used with KEZHE TLC scanners, the software auto-associates plate metadata (batch ID, development time, solvent system) with physical storage location (shelf ID + slot number), enabling full chain-of-custody tracking. Audit trails record all manual shelf adjustments (timestamped, operator-ID logged) and environmental logs (if paired with optional external温湿度 sensor module), satisfying FDA 21 CFR Part 11 electronic record requirements when deployed in regulated QC environments.
Applications
- Routine QC/QA labs performing identity/purity testing per USP , EP 2.2.27, or JP 6.07 monographs.
- Natural product research labs requiring stable storage of bioactive compound separations prior to HPLC fraction collection.
- Academic teaching facilities needing robust, student-safe infrastructure for multi-session TLC experiments.
- Pharmaceutical stability studies where plate re-scanning after accelerated aging (40°C/75% RH) demands strict positional repeatability.
- Regulatory submission support: Enables documented plate retention per ICH M4Q(R2) Annex 2 requirements for raw chromatographic data archiving.
FAQ
Is the TB-2 compatible with non-KEZHE TLC scanners?
Yes—its mechanical dimensions and plate-handling interface conform to ISO/IEC 17025 Annex A3 universal TLC plate specifications; however, software-level integration (e.g., auto-location tagging) is exclusive to KEZHE VisionTLC Suite.
Can the cabinet be used for active heating during plate drying?
An optional PTC ceramic heater module (max 80°C, ±1.5°C uniformity) is available as an add-on; standard configuration relies on ambient air convection only.
Does the TB-2 meet cleanroom classification requirements?
It is rated ISO Class 8 (100,000) when operated with HEPA recirculation mode and validated cleaning protocol; Class 7 compliance requires optional laminar flow retrofit.
What maintenance is required for long-term calibration stability?
Annual verification of shelf leveling accuracy using certified spirit level and width gauge is recommended; no recalibration of mechanical components is needed under normal usage.
Are replacement shelves or custom-sized inserts available?
Yes—KEZHE offers OEM-machined stainless steel shelves (0.5 mm thickness tolerance) and polymer edge guides for non-standard plate formats (e.g., circular 100 mm diameter plates).
