For absorption measurements in miniaturized centrifuge tubes or vessels, Avantes offers the mini transmission dip probe. It features a miniaturized tip which is 130mm long and 3.2mm in diameter.
The mini transmission dip probe has a fixed 5 or 10-mm optical path length. It is available in three different versions: one for UV/VIS (200-800 nm) measurements, one for VIS/NIR (350-2500 nm) and one for UV/VIS/NIR (250-2500 nm), for best results below 240 nm, solarization-resistant fiber (-SR) is recommended. The probe features Avantes ME, chrome-plated brass, and jacketing.
The probe can optionally be configured with a longer stainless steel or Hastelloy® tip or other jacketing options (MS, BX, or PVC). The probe has two SMA connectors (FC/PC also available) for convenient coupling to the Avantes line of spectrometers and light sources.
