TPP® Clipmax Chamber Slide System

The TPP® Clipmax Chamber Slide System (10 cm²) is a unique combination of a tissue culture flask and a removable microscope slide (25 x 75 mm), designed to simplify your cell culture and imaging workflows. Grow cells directly in the chamber, then remove the slide for easy fixation, staining, and imaging - without the need for transfer steps that increase contamination risk.

Clipmax is especially suited for cell culture, immunocytochemistry (ICC), immunofluorescence (IF), and cell analysis workflows, allowing you to work directly on the crystal-clear microscope slide for reliable, reproducible results.

Main Attributes

Optimal Optical Clarity

• Crystal-clear plastic microscope slide designed for cell imaging
• Suitable for staining, fixation, and especially for immunofluorescence measurements
• Solvent-resistant surface (acetone, ethanol, xylene) 

• Cell culture chamber slide for imaging and analysis
• Immunocytochemistry (ICC) and immunofluorescence (IF) studies
• Staining and fixation directly on the microscope slide
• Ideal for researchers needing a media-saving, solvent-resistant, chambered slide system

directly on one slide. Contact us today for a sample! 

TPP® Slidemax Chamber Slide System

Maintain optimal conditions for cell growth.

The TPP® Slidemax is a high-quality slide made of cyclo olefin polymer (COP) featuring an integrated chamber system. It allows experiments to be performed efficiently on a single slide and is available in variants with 1, 2, 4, or 8 chambers.

Adherent cells can be fixed and stained directly within the chambers on the activated growth surface, eliminating time-consuming transfers and minimizing the risk of cell loss. COP provides excellent optical properties thanks to its low autofluorescence, enabling high-resolution microscopy at wavelengths below 300 nm.

Its chemical resistance allows the use of organic solvents for various staining techniques. Only the growth surface of the slide is opto-mechanically activated, ensuring optimal cell adhesion and enhanced cell growth. This activation supports the efficient cultivation of adherent cells, enabling precise and reproducible experimental results.

The Slidemax lid ensures consistent and optimal gas exchange while minimizing evaporation through integrated spacers. The chamber and slide are permanently joined by ultrasonic welding, creating a robust and continuous material bond. This manufacturing process ensures a reliable and closed system under normal operating conditions. The TPP® Slidemax system is permanently sealed during manufacturing and must therefore be regarded as a closed system. Once the seal has been compromised or opened, its integrity cannot be restored.

Main Attributes

• COP microscope slide
• Available in 1-, 2-, 4-, 6-, and 8-well formats
• Very low autofluorescence
• Surface-treated for demanding cell types
• Suitable for staining and immunofluorescence applications
• Resistant to acetone, ethanol, and xylene
• Lid with integrated spacers for continuous gas exchange
• Snap-off culture chamber, no tools required
• Stackable design
• Tamper-evident seal
