Clinox XinPRO Series Mini Vertical Electrophoresis Tank

Overview

The Clinox XinPRO Series Mini Vertical Electrophoresis Tank is an engineered solution for high-fidelity protein separation via slab-gel electrophoresis, with primary application in isoelectric focusing (IEF) and SDS-PAGE workflows. Designed around the Couette-flow principle of vertical gel casting and uniform electric field distribution, this system enables reproducible polymerization and migration under controlled thermal and mechanical conditions. Its compact footprint and modular architecture align with modern laboratory space constraints without compromising structural integrity or electrophoretic resolution. The tank supports standard polyacrylamide gel electrophoresis protocols compliant with ISO/IEC 17025-accredited laboratories and meets foundational design criteria referenced in ASTM D4290 (Standard Guide for Electrophoretic Separation of Biomolecules) and USP (Electrophoresis).

Key Features

• Modular gel-casting base with streamlined, non-spring clamping mechanism—eliminates long-term compression fatigue and seal failure associated with coil-spring systems.
• Fixed edge-sealing spacers mounted directly to the long glass plate ensure precise alignment between short and long plates, minimizing gel leakage during polymerization.
• Cam-actuated gel frame guarantees repeatable dimensional registration across multiple casting cycles, maintaining consistent gel thickness and well geometry.
• Ultra-flat borosilicate glass support platform at the base of the casting frame prevents lateral slippage of glass plates during acrylamide pouring and polymerization.
• Full-plate reverse backlighting integrated into the base allows real-time visual monitoring of stacking and resolving gel layer formation, enhancing protocol consistency.
• Wedge-profile electrode chamber side clips slide parallel—not rotate—ensuring uniform compressive force on sealing steps and eliminating fluid egress caused by incomplete cam engagement.
• Comb inserts feature toothed edges and internal ridges that physically isolate polymerizing gel from ambient oxygen, mitigating inhibition of free-radical polymerization and ensuring complete crosslinking.
• All glass plates and combs are laser-etched with nominal thickness (e.g., 1.0 mm, 1.5 mm) and well count (e.g., 10-, 15-, or 20-well), enabling rapid identification and traceability within multi-user lab environments.
• Reinforced edge-sealing spacers increase overall plate rigidity, reducing fracture risk during handling, washing, or staining procedures.

Sample Compatibility & Compliance

The XinPRO tank accommodates standard vertical polyacrylamide gels (up to 83 mm × 73 mm active area) and is compatible with common IEF gel formulations (e.g., pH 3–10, 4–7, or narrow-range ampholyte gradients). It supports both hand-poured and pre-cast gel formats when used with auxiliary casting accessories. The system conforms to general electrical safety standards per IEC 61010-1 for laboratory equipment and is constructed using UL94-V0 rated flame-retardant polymers. While not certified for GLP/GMP production environments, its design supports audit-ready documentation practices—including lot-specific gel plate logs and voltage/current calibration records—when integrated into FDA 21 CFR Part 11–compliant LIMS or ELN platforms.

Software & Data Management

As a standalone electrophoresis tank, the XinPRO Series does not incorporate embedded firmware or digital control interfaces. However, it is fully interoperable with third-party power supplies (e.g., Bio-Rad PowerPac Basic, Thermo Fisher Owl E2 series) equipped with programmable voltage ramping, current limiting, and time-based shutdown. When paired with imaging systems such as Clinox GelView or Syngene G:BOX chemi, raw electropherograms can be imported into ImageLab, Quantity One, or open-source tools like Fiji/ImageJ for densitometric quantification, molecular weight estimation, and pI mapping—supporting FAIR data principles (Findable, Accessible, Interoperable, Reusable).

Applications

• High-resolution isoelectric focusing of complex protein mixtures (e.g., serum, cell lysates, recombinant expression supernatants).
• Two-dimensional electrophoresis (2-DE) first-dimension IEF followed by second-dimension SDS-PAGE.
• Validation of protein purity, post-translational modifications (e.g., phosphorylation, glycosylation), and charge heterogeneity.
• Preparative-scale gel electrophoresis for downstream mass spectrometry sample preparation.
• Teaching laboratories requiring robust, low-maintenance vertical electrophoresis platforms aligned with undergraduate biochemistry curricula.

FAQ

Is the XinPRO tank compatible with pre-cast gels?
Yes—when used with optional gel-loading adapters and buffer chamber inserts, it accepts commercially available pre-cast polyacrylamide gels of matching dimensions.
What power supply specifications are recommended?
A constant-voltage or constant-current supply capable of delivering 100–500 V DC and up to 500 mA is optimal; compatibility has been verified with outputs ranging from 50–2000 V and 1–2000 mA.
Can the tank be sterilized for sterile technique applications?
The acrylic housing and silicone gaskets tolerate 70% ethanol wipe-down and UV irradiation (254 nm, 30 min); autoclaving is not advised due to thermal deformation risk.
Are replacement glass plates and combs available separately?
Yes—Clinox offers OEM-specified glass plates (1.0 mm and 1.5 mm thicknesses), multi-well combs (10-, 15-, and 20-well), and sealing spacers through authorized distributors with documented lot traceability.
Does the system support temperature-controlled electrophoresis?
No built-in cooling; however, the low thermal mass design permits integration with external recirculating chillers via custom buffer chamber manifolds—commonly deployed for high-voltage IEF runs exceeding 1,500 V.
