CK-1 Cleaning Chamber for Microscopy Sample Preparation

Overview

The CK-1 Cleaning Chamber is a precision-engineered accessory designed for controlled sample preparation and post-imaging cleaning in high-resolution light microscopy workflows. Developed by NARISHIGE—a Japanese manufacturer with decades of expertise in micromanipulation and optical instrumentation—the CK-1 serves as a dedicated chamber for gentle rinsing, solvent exchange, or immersion medium conditioning of glass coverslips and delicate biological specimens. Its operational principle relies on passive fluid dynamics: the shallow, radially symmetric cavity—formed by a flat borosilicate glass base and a softly contoured silicone gasket—creates a laminar flow profile during liquid introduction. This geometry minimizes shear stress and turbulence, preventing mechanical disruption of fragile cellular structures or fluorescent labels while enabling uniform meniscus formation. The chamber is not a standalone analytical instrument but an integral component in GLP-compliant slide preparation protocols, particularly where reproducibility of surface wetting, refractive index matching, and contamination control are critical—such as in TIRF, confocal, or super-resolution imaging.

Key Features

• Borosilicate glass base ensures optical clarity, thermal stability, and chemical resistance to common aqueous and organic solvents (e.g., ethanol, xylene, PBS, glycerol-based mounting media).
• Gentle radial slope design promotes uniform fluid entry and stabilizes the capillary-driven dome shape of the meniscus—reducing edge artifacts and improving immersion lens coupling consistency.
• Reusable stainless steel clamping fixture provides secure, non-marring fixation of coverslips without deformation; compatible with standard #1.5 (0.17 mm) and #1 coverslips (0.13–0.16 mm).
• Integrated silicone rubber gasket (FDA-compliant, autoclavable up to 121°C for 20 min) ensures leak-tight sealing while accommodating minor thickness variations across commercial coverslip batches.
• Modular construction enables rapid disassembly: all components are non-threaded, tool-free, and compatible with ultrasonic cleaning, plasma treatment, and ISO 13485-aligned sterilization validation protocols.

Sample Compatibility & Compliance

The CK-1 is validated for use with standard microscope coverslips (22 × 22 mm, 24 × 50 mm, and round 12 mm/18 mm formats), hydrophilic/hydrophobic surface-modified substrates, and thin-film biosensors. It supports both aqueous (e.g., deionized water, buffered saline) and oil-based immersion media (e.g., Type F, Type N, Cargille immersion oils). The device complies with ISO 8596:2017 (Ophthalmic optics — Fundamental requirements for ophthalmic instruments) regarding optical material purity and surface defect limits. While not a medical device itself, its materials meet USP Class VI biocompatibility standards, and its design facilitates adherence to FDA 21 CFR Part 11 requirements when integrated into electronic lab notebook (ELN)-linked microscopy SOPs—particularly through traceable cleaning logs and gasket replacement tracking.

Software & Data Management

The CK-1 operates entirely manually and requires no embedded firmware, drivers, or proprietary software. However, it integrates seamlessly into digital microscopy workflows via standardized documentation practices: users may log chamber usage (e.g., lot number of coverslips, immersion medium batch ID, cleaning cycle parameters) directly into LIMS or ELN platforms such as LabArchives or Benchling. Its physical design supports barcode labeling on the base plate for asset tracking, and the included silicone grease is supplied with CoA (Certificate of Analysis) traceable to Lot #, enabling full chain-of-custody compliance in regulated environments including clinical research laboratories operating under CLIA or CAP accreditation.

Applications

• Routine cleaning and dehydration-rehydration cycling of reusable coverslips in core imaging facilities.
• Controlled solvent exchange during resin infiltration for EM sample preparation (e.g., transitioning from acetone to Epon).
• Pre-immersion conditioning of high-NA objective lenses to eliminate air bubbles at the oil-glass interface.
• Surface passivation verification using contact angle measurement setups—where consistent meniscus geometry is essential for repeatability.
• Training modules for microscopy technicians on contamination mitigation, meniscus management, and aseptic handling of optical interfaces.

FAQ

Is the CK-1 compatible with inverted microscopes?
Yes—the low-profile 8 mm height allows unobstructed access for long-working-distance objectives and motorized stage navigation.
Can the silicone gasket be replaced independently?
Yes—gaskets are supplied as consumables (Cat. No. GSK-CK1) and certified for ≥50 autoclave cycles without swelling or extractables increase.
Does NARISHIGE provide calibration documentation for the CK-1?
No calibration is required, as the CK-1 is a passive mechanical device; dimensional tolerances are held to ±0.05 mm per JIS B 0401 Grade IT7.
What is the maximum temperature exposure limit for the glass base?
Borosilicate glass withstands continuous use up to 500°C; however, thermal shock resistance is optimized for ambient-to-60°C transitions only.
Are custom-sized coverslip variants available?
NARISHIGE offers OEM configuration support for non-standard dimensions under MOQ 50 units; lead time is 12 weeks from approved drawing submission.
