The Countess 3 Automated Cell Counter uses advanced machine-learning image analysis algorithms to deliver accurate cell counts and viability in seconds with the convenience of fully automated lighting, focus, capturing, counting, and saving thereby reducing the time and variability associated with manual cell counting.

The Qubit dsDNA broad range assay kit is designed specifically for use with the Qubit Fluorometer. The assay is highly selective for double-stranded DNA (dsDNA) over RNA and is designed to be accurate for initial sample concentration from 100 pg/µl–1,000 ng/µl.

Simply add your sample (between 1 µL and 20 µL) to the ready-to-use solution and read the dsDNA concentration (10 pg/µL to 100 ng/µL) on the Qubit Fluorometer

Accurate and sensitive quantification of DNA, RNA, and protein with flexible throughput

The TOPO™ XL-2 Complete PCR Cloning Kit provides all the necessary elements for efficient cloning of extra-long PCR products (up to 13 kb).

Absolute characterization of protein-protein and other macromolecular interactions with composition-gradient multi-angle light scattering.

Automated characterization of protein/nanoparticle size, stability and molecular weight in industry-standard microwell plates

Use with any standard male luer end SPE cartridges. Inert, PTFE sample guides reduce cross-contamination and carryover. Flexible sample collection rack will accommodate a variety of receiving vessels. Quick vacuum-release valve for better system control. Individual valves allow vacuum control for each cartridge, improving reproducibility.
