The TopCountTM Microplate Scintillation Counter quantitates radioisotopes by liquid scintillation counting in standard microplate formats. Assays that previously had to be transferred from microplates to vials or to non-standard formats for counting can now be quantitated directly in microplates. TopCount can count up to 12 samples simultaneously with performance comparable to that of discrete ...

Parallel liquid handling systems are widely used in different applications of life sciences. In order to avoid false positive or negative results which lead to higher costs due to the replication of the experiments it is necessary to monitor the process and success of liquid delivery. An easy method for the determination of the liquid levels in microplates has been developed and evaluated. The ...

The purpose of this study is to investigate the effect ultrasound and/or organic acids against Escherichia coli and Listeria monocytogenes biofilms on microplates. In inactivation trials, pathogen formed microplates were exposed 2% acid (acetic, citric, malic lactic acid) for 10, 30 60 minutes. Biofilm detachment treatment with US was tested by microplate method based measuring optical density....

Glucose was used to synthesize high-quality Cu microplates which underwent in situ large-scale assembly into puzzle-like patterns. The micropuzzles were applied to nonenzymatic glucose sensors. The as-prepared Cu micropuzzle-modified electrode shows good linear dependence and high sensitivity and selectivity to glucose concentration change.
