Grant Bio DEN-600 Photometer

The Grant Bio DEN-600 is a compact, portable, and rechargeable photometer designed for fast and accurate optical density measurements at 600 nm. Ideal for microbiology and protein analysis workflows, this device provides a reliable and cost-effective alternative to traditional spectrophotometers.

The DEN-600 supports multiple measurement methods, including:

• OD600 readings for estimating total cell concentration
• McFarland turbidity measurements (McF) for microbial standardization
• Bradford protein assay for protein quantification

Its lightweight, battery-powered design allows convenient use inside biosafety cabinets, anaerobic chambers, or any workspace requiring quick relocation. The versatile cell holder accommodates standard 10 mm cuvettes, round-bottom tubes, conical vials, and Falcon tubes. With USB connectivity and integrated DEN software, users can easily transfer, analyze, and calculate data for streamlined laboratory workflows.

Applications

• Cell concentration measurement
• Cell growth and culture density estimation
• Logphase detection for microbial induction
• Competent cell preparation
• Bradford protein quantification
• Antibiotic susceptibility testing
• Inhibitory testing

DEN MCF Standards (DENMCFSTDS)

The DEN-600 is compatible with a set of liquid McFarland standards in 16 mm glass tubes (0.5/1.0/2.0/3.0/4.0). Standards may be transferred into alternative tubes.

*Shelf-life no longer valid after transfer. Requires D16 adaptor.
