Using the advanced Czerny- Turnermonochromator design with optimization of the optical sys tem, baseline change due to refrac tive index is minimized.Baseline fluctuation from changes in environmental temperature is reduced with a temperature - controlled cell, baseline drift caused by temperature fluctuation in the light source is also reduced with a temperature controlled light source. The result is excellent stability with…

The FP-8500 spectrofluorometer has an optimized optical design for very low stray light and a dynamic range of up to 6.5 orders of magnitude. It is exceptionally sensitive with a Raman S/N ratio of 5,000:1 (RMS), which allows for fast measurements of samples with low level fluorescence. The high spectral resolution of 1.0 nm, automatic band-pass filters for exclusion of higher-order diffraction, and accurate spectral correctio…

Elegant and simple to use, the BV-10 offers precision beveling of micropipette tips between 0.1 and 100µm. The unique abrasive plate drive system is vibration free for greater control of the beveling process. Beveling can be accomplished very rapidly and produces consistent tip diameters using the techniques as described by Brown and Flaming, Science, August 1974, Vol. 185. Intracellular recording electrodes can benefit from…

The 902 Titrando expands the Titrando system by adding the modes pH STAT titration and controlled dosing. STAT titration The determination of the activity of an enzyme or the monitoring of the release kinetics of antacid drugs requires a titrator that rapidly adjusts a predefined pH value and keeps it constant over a long time period. The 902 Titrando's controller has been optimized for this task and is among the best avai…
