Nano-volume spectrophotometer

The NanoPhotometer® P-Class is an All-in-One spectrophotometer with proven micro volume (0.3μl) and cuvette performance.

Optimized for quantification and purity assessment of nucleic acid and protein samples, the NanoPhotometer® P-Class brings unmatched performance and features in a flexible, compact, and easy to use spectrophotometer.

The features are

  • Flexibility & mobility: All-in-One Small volume and cuvette capability always standard; Standalone mobile design with large LCD display and available thermal printer for convenient direct printing; Electronic data can be automatically generated in a variety of file formats when connected to a PC; USB flash drive, Bluetooth or SD-Memory capability is available on selected models
  • Detection range: Widest concentration coverage Apply NanoVolume samples directly without dilution; Optical alignment, high linearity, and automatic dilution provide the widest concentration range of dsDNA 2-18,750 ng/µl and protein (BSA) 0.08-543 mg/ml
  • Standardization: Instant Ready Technology™ Optimized Sample Condition Ensure homogeneous samples with built-in low vibration vortexer option for consistent readings and accurate results over the entire life-time
  • Small: 0.3 µl sample volume Compression Technology™ allows for accurate determination of nucleic acids, proteins, and peptides in ultra low sample volumes
  • Fast: 3.5 seconds per reading turn on and instantly measure without lamp warm up time; Full scan capability from 200-950nm in 3.5 sec
  • Accurate: Lifetime accuracy without recalibration,Sealed optics without moving parts or pathlength drift eliminates the need for costly and time consuming recalibrations; Avoid evaporation and sample limitations utilizing the patented Sample Compression Technology™
