The Hamilton Multi-Channel Gel Loading Syringe (MCGLS) easily and accurately transfers 8 or 12 DNA samples to sequencing gels for electrophoresis, to another microwell plate for duplicate analysis, or to nylon membranes for visualization. Samples can be easily transferred by microwell plate column using the 8-channel pipette, or by row using the 12-channel pipette. A single DNA Syringe is also available for individual transfers. Three different needle specifications allow either loading of samples into thin sequencing gel wells that are 0.2 mm (.008 in), 0.3 mm (.012 in) or 0.4 mm (.016 in) or larger, or directly onto the top of the sequencing gel. The standard needle spacing of 9 mm (.354 in) allows spotting between the gel plates using most square or sharkstooth combs with a microwell format. An adjustable stop collar on the MCGLS allows you to pre-set the volume anywhere between 0.2 to 10 µL.
