BioTek Instruments, Innovatis

BioTek Instruments announced this week that it has launched the EL406 microplate washer dispenser. The EL406 offers microplate washing along with both peristaltic and microprocessor-controlled syringe drive reagent dispenser technologies to optimize liquid handling processes in microplate format, the company said.
The EL406 integrates both peristaltic and syringe drive dispensing, and up to three reagents may be dispensed at one time using either technology.
Washing is available with up to four buffers, and BioTek's Dual Action manifold provides independent control of aspirate and dispense functions. Integrated Ultrasonic Advantage provides automatic wash manifold maintenance to eliminate clogged manifold tubes, the manufacturer said.
The EL406 may be interfaced with the BioStack microplate stacker for automated processing of up to fifty standard height microplates.

Innovatis this week announced the introduction of CuBiAn, a fully automated, membrane-free chemical analyzer that measures parameters in cell culture media, including IgG.
All assays are prepared, incubated, and measured by the instrument. Pipetting, sample pre-dilution, and temperature control are all automated to provide assay ranges (IgG 10µg/ml - >20 g/L).
The CuBiAn technology is able to detect IgG concentrations along with 11 different metabolites in a single sample and sequence, the manufacturer said. IgG is detected by immuno-turbidimetry, while all other molecules are quantified by photometric enzyme assays.
The key parameters measured are IgG (human, humanized), glucose, lactate, ammonia, glutamine, glutamate, inorganic phosphate, LDH, total protein, and Na+, K+, and Cl-. CuBiAn requires low sample volumes, and is capable of providing 90 results per hour (and 360 results with an ISE unit).
