Lifestyle Visions quartz cuvettes are made out of clear rich purity quartz materials to adapt to the needs of a variety of spectrophotometer laboratory studies. The cuvettes are acid and alkali resistant. Each quartz cuvette holds 3,500 of microliters. The cuvettes are Type 1 with two sides frosted and two sides polish. The heat resistant are able to withstand high temperature up to 600 ℃. .
These cuvettes have a standard 12.5 mm square outside dimension and a 10 mm light path through the sample. The es quartz cuvettes transmittance of light is above 83%. The Cuvette design allows the light beam to come through the front window and exit the back window of the cuvettes..
The highly transparent UV cuvettes require as little as a sample for accurate and precise quantitation of DNA, RNA, and proteins..
UV-transparent cuvettes that are suitable for most UV and visible spectroscopic assays.
supplement to their use when working with precious DNA or RNA samples..
Standard spectrometer cuvette comes in a pack of four with the outer dimension: 45 mm x 12.5 mm x 12.5 mm..
