Hellma® Traycell 2.0 mm (Factor*100) Cap

This Hellma TrayCell Cap has a small mirror that works with the TrayCell accessory (L7110289) to ensure a constant pathlength of 2 mm when measuring samples. These measurements are then adjusted by a factor of 100 to make them equivalent to measurements taken in a 1 cm cell.

The Hellma® Traycell Accessory is a fiber-optic, ultra-micro cell designed for UV/Vis analysis of DNA/RNA and proteins. The dimensions of the TrayCell are equivalent to a standard cuvette, allowing it to work in most spectrophotometers. LAMBDA spectrometers require a beam height of 15 mm.

Features and Benefits include:

  • Suitable for almost any current spectrophotometers
  • Ideally suited for very small measurement volumes: 0.7 L to 10 L
  • Trouble-free measurement of the sample at different optical path lengths simply by exchanging the cap [caps with dilution factors: 5, 10, 50 and 100]
  • Fast and simple cleaning of the optics before measuring the next sample - the TrayCell remains in the cell holder!
  • Samples can be reused after the measurement simply by piping them off
  • During measurements, TrayCell shows excellent shows excellent reproducibility.
