Clinkx XinPAGE Mini Vertical Electrophoresis Tank

Overview

The Clinkx XinPAGE Mini Vertical Electrophoresis Tank is an engineered solution for high-reproducibility SDS-PAGE and native PAGE applications in molecular biology, proteomics, and quality control laboratories. Designed around the principles of constant-voltage or constant-current electrophoretic separation in polyacrylamide gels, the system supports standardized protein mobility analysis under controlled thermal and electrical conditions. Its compact vertical architecture accommodates standard mini-gel formats while integrating mechanical and electrical safety features aligned with international laboratory equipment standards (IEC 61010-1 and GB/T 2900.88). The unit operates without external cooling modules but maintains thermal stability during typical 30–90 min runs via passive heat dissipation and low-resistance electrode pathways—critical for minimizing band distortion and ensuring inter-run consistency.

Key Features

• Single-hand operational design: Integrated latch-style lid enables one-handed opening/closing; lid orientation is mechanically constrained to prevent misalignment and ensure automatic electrical disconnection upon removal.
• Durable gold-plated spring-pin electrodes: Precision-machined 1.6 mm × 1.0 mm contact pins deliver stable conductivity over >100,000 insertion cycles; corrosion-resistant plating ensures long-term signal integrity across repeated buffer exposures.
• In-situ gel casting capability: Gel pouring, polymerization, and electrophoresis occur within the same chamber—eliminating gel transfer steps, reducing contamination risk, and improving alignment repeatability between runs.
• Modular pre-cast gel compatibility: Accommodates widely available stepless pre-cast gels (e.g., Bio-Rad Criterion, Thermo Fisher Novex, Lonza eGels), enabling rapid assay deployment without acrylamide handling.
• Standardized mini-gel format support: Accepts glass plates measuring 100 mm × 85 mm and yields gels of 100 mm × 75 mm × 1.0 mm—fully compatible with downstream Western blotting, staining, and densitometric quantification workflows.
• Regulatory-ready electrical safety architecture: Power supply interface complies with IEC 61010-1 and GB/T 2900.88 for measurement, control, and laboratory use; all conductive paths are double-insulated and grounded per Class I appliance requirements.

Sample Compatibility & Compliance

The XinPAGE Mini supports a broad range of sample types including denatured and native proteins, protein complexes, and small peptides (1–250 kDa range). Its 1.0 mm gel thickness ensures optimal resolution for Coomassie- and silver-stained bands while maintaining mechanical stability during handling. Buffer systems include Tris-Glycine, Tris-Tricine, and Bis-Tris MOPS, with compatibility verified for both hand-poured and pre-cast gels lacking comb-step features. From a regulatory standpoint, the device meets essential safety requirements for GLP-compliant environments; its fixed-lid interlock mechanism and auto-disconnect function satisfy functional safety criteria outlined in ISO 13857 for accessible hazardous voltage zones. While not a medical device, its construction and documentation align with general-purpose lab instrument expectations under FDA 21 CFR Part 11–adjacent operational traceability frameworks when paired with compliant power supplies and data loggers.

Software & Data Management

As a standalone electrophoresis tank, the XinPAGE Mini does not incorporate embedded firmware or digital interfaces. However, it is fully interoperable with third-party imaging systems (e.g., Azure Biosystems Sapphire, Bio-Rad ChemiDoc) and analysis platforms (ImageLab, AlphaView SA, Fiji/ImageJ) via standardized gel dimensions and UV-transparent cassette materials. Users may document run parameters—including voltage, current, time, and buffer composition—in laboratory notebooks or LIMS-compatible templates. For audit readiness, manual logs can be structured to reflect critical process parameters (CPPs) as defined in ISO/IEC 17025:2017 Clause 7.7 (result reporting) and USP analytical instrument qualification guidelines.

Applications

• SDS-PAGE for protein molecular weight estimation and purity assessment in biopharmaceutical QC labs
• Native PAGE analysis of oligomeric states and protein–ligand interactions
• Western blotting workflow integration—direct transfer from gel to membrane without intermediate handling
• Educational training in core electrophoresis theory and technique, including troubleshooting of common artifacts (smiling, streaking, poor resolution)
• Preparative electrophoresis for excision-based mass spectrometry sample preparation

FAQ

Is the XinPAGE Mini compatible with standard mini-gel electrophoresis power supplies?
Yes—it accepts standard DC outputs up to 300 V / 400 mA and features universal banana jack inputs compliant with most commercial power supplies (e.g., Bio-Rad PowerPac Basic, C.B.S. Scientific EPS-200).

Can I use this system for gradient gels?
Yes—the in-situ casting design supports gradient gel preparation using dual-chamber pourers or programmable gradient mixers; gel thickness uniformity is maintained across 4–20% T gradients.

Does the unit include glass plates and combs?
Yes—each XinPAGE Mini system ships with two sets of 100 mm × 85 mm glass plates, sealing cassettes, and interchangeable 10-well and 15-well combs (1.0 mm thickness).

What maintenance is required for the gold-plated electrodes?
No routine maintenance is needed; electrodes are sealed within the base assembly and require only periodic visual inspection for physical damage or buffer residue accumulation after extended use.

Is technical documentation available in English for regulatory submission packages?
Yes—CE-marked declaration of conformity, IEC 61010-1 test reports, and dimensional drawings are provided upon request for inclusion in validation protocols or audit dossiers.
