Molecular Devices introduces new Digidata 1550A

US-based Molecular Devices has introduced new Digidata 1550A, a digitizer with built-in adaptive noise cancellation technology HumSilencer.

The new low-noise data acquisition system has been developed for the analog-to-digital conversion of biological signals measured in electrophysiology experiments.

The cancellation technology is said to provide single-click elimination of the 50Hz and 60Hz line-frequency noise that can severely impair analysis of biological signals.

According to the company, the dysfunction of ion channels that regulate the flow of ions in and out of cells is implicated in numerous neurological and cardiovascular diseases.

Molecular Devices strategy and product marketing vice-president Martin Verhoef said: "Prepping patch clamp recordings is time consuming. The last thing one needs is to delay the experiment while hunting down the offensive electrical source that’s causing interference.

"The Digidata 1550A plus HumSilencer is an integrated system that eliminates this noise by a single-click, saving time and increasing the data quality of patch clamp recordings."

In addition, the HumSilencer technology in the system identifies local line-frequency noise and inhibits extraneous noise amplitude up to 20V peak to peak at the analog input in less than one second.

Molecular Devices provides bioanalytical measurement systems, software and consumables for life science research, pharmaceutical and biotherapeutic development.
