Film Strip Carrier KAISER 6507 — black film strip holder for enlargers and scanners

KAISER Film Strip Carrier 6507 is a black film strip holder designed to secure and position strips of 35 mm negatives for use with enlargers, film scanners and digital slide duplicators. The carrier accepts strips with up to six unmounted 35 mm frames and holds them flat and aligned to enable consistent framing, accurate exposure and reliable scanning or copying. Constructed for photographic darkroom and digitization workflows, it provides a stable platform for optical reproduction without contacting the emulsion surface.

Advantages

The film strip carrier offers precise film alignment and consistent spacing between frames, reducing the need for repeated adjustments during enlargement or scanning. Its black finish minimizes stray reflections and improves contrast control when working with lightboxes, enlarger heads or scanner light sources. The holder protects negatives from unnecessary handling and helps maintain flatness to avoid focus and registration errors. It is compact and compatible with standard strip film formats used in photographic and digitization equipment.

Suitable for

• Digitizing strips of 35 mm negatives with a film scanner or digital camera duplicator
• Making enlargements from multiple 35 mm frames in a darkroom enlarger
• Batch scanning or copying sequences of unmounted slide frames
• Archival reproduction and documentation of negative strips

Key specifications

• Material: rigid black carrier compatible with photographic use
• Capacity: holds up to six 35 mm unmounted frames per strip
• Finish: non-reflective black surface to reduce stray light and reflections
• Compatibility: fits standard 35 mm strip film formats and common enlarger/scanner duplicator setups
• Function: secures negatives flat for accurate focus, framing and exposure

How to use

Load the film strip by aligning the perforations or frame edges with the carrier guides and slide the strip into the holder until it sits flat and securely. Place the loaded carrier into the film gate of your enlarger, scanner or digital slide duplicator according to the device’s instructions, ensuring the carrier is seated evenly to maintain parallelism between the film and the imaging plane. Adjust focus, framing and exposure settings on your enlarger or scanner, then expose or scan each frame in sequence. Remove the strip by gently withdrawing it from the carrier to avoid scratching the emulsion.

Recommendations

Handle film by the edges and avoid touching the emulsion. Clean the carrier and device film gate periodically with a soft brush or blower to remove dust. For best results when scanning, use consistent exposure settings and, if available, employ dust and scratch removal or multi-sampling features in the scanner software.
