Detection of bacterial endotoxins using the PYROSTAR™ ES-F/Plate LAL assay
Perform the PYROSTAR ES-F/Plate LAL test your way— BMG LABTECH readers support both turbidimetric and nephelometric evaluation for maximum flexibility.
O primeiro e único nefelômetro de microplacas baseadas em laser do mundo foi desenvolvido para atender às demandas de alto rendimento para telas de solubilidade de compostos rápidos. O NEPHELOstar® Plus detecta partículas insolúveis em amostras líquidas através da medição da luz dispersa para frente e pode ser usado para medições de turbidez, triagem de solubilidade de drogas, cinética de ligação de proteína, crescimento microbiano e controle de processo de petróleo.

O NEPHELOstar Plus é um nefelômetro de microplacas com um diodo laser de alta intensidade. Pode ser até trinta vezes mais sensível do que os leitores de densidade óptica de transmissão tradicionais que medem a redução na luz direta que passa por um poço de amostra. Graças à sua velocidade, flexibilidade e desempenho, o NEPHELOstar Plus permite que mais aplicações sejam adaptadas à nefelometria laser baseada em microplacas do que nunca.
O NEPHELOstar Plus é apenas para uso em pesquisa.

Nephelometric turbidity units (NTUs) refer to the concentration of particles to describe the quality of water. Read how the NEPHELOstar® Plus microplate nephelometer determines NTUs in low sample volume.
Laser nephelometry was used for the rapid determination of the solubility of potential antimycotic drug compounds and for the measurement of fungal growth in the microplate format.
An alternative method to test Rheumatoid Factors by microplate nephelometry provides an inexpensive assay that can be used in medium- to high-throughput labs. Read more here!
