Starna Scientific Development department has designed and patented a new ultra-micro volume fluorescence lens cell to perform UV/Visible spectrofluorometer analysis on smaller volume samples of typically five microlitres or less.
The ultra-micro cell provides a practical solution for customers where samples cannot be prepared in or diluted to larger volumes.
Starna’s Type 19FL ultra-micro cell, which avoids the need for dilution, thereby minimizing reagents costs, is well suited to providing analysis in volumes typically handled in molecular biology and forensics applications.
By offering high sensitivity, even in very small volumes, the Type 19FL ultra-micro cell is also suited to proteomics applications, where the sensitivity of the cell is sufficiently high to measure native fluorescence of proteins prepared in microlitre quantities. The cell design also allows the majority of the sample to be recovered.
The type 19FL ultra-micro lens cell is designed to enable ultra low volume fluorescence measurements in the 5 ul sample volume range.
The cell allows good quality fluorescence measurements to be achieved using a conventional spectrofluorometer at sample volumes.
Using Far UV non-fluorescence quartz, the Type 19FL Ultra-micro volume fluorescence lens cell, 5 mm path length, can be supplied with a ‘Z’ height of 8.5, 15, and 20mm, and has been designed to make loading and flushing simple, with minimum dead volume.
