TTP Labtech mosquito HV liquid handler

Click2Contact

The mosquito HV from TTP Labtech has been developed to allow scientists to accurately handle low-volume serial dilutions and assay plate preparations across the 500 nL to 5 µL range. In addition, the product can rapidly perform serial dilutions in the 2-8 µL final volume range and can stamp from a mother plate directly to assay plates as part of the same protocol, saving laboratory time.

The device retains all the features of the company’s mosquito range of nanolitre liquid handlers, including its positive displacement pipetting technology for fast, accurate dispensing of sample volumes, regardless of viscosity. The product’s larger disposable micropipettes ensure zero cross-contamination and reach right to the bottom of wells, minimising dead volume to under 50 nL per well. The product also offers accuracy to within 2% of target volume. It is available in an HTS format for screening and an X1 format for hit picking applications.

The device offers flexibility in the low volume range for highly accurate sample dispensing and handling for a wide range of chemical- and biological-based applications beyond serial dilutions and plate reformatting. These include compound and small molecule screening, cell- or bead-based assays, enzyme kinetics assays, ELISAs, molecular biology applications such as PCR, RNAi screening and SNP genotyping.

The product’s accurate and precise pipetting and mixing capabilities ensure good quality, repeatable data with CVs of below 2.5% throughout its volume range, while minimising run times and reagent wastage.
