System Highlight
Efficiency: The Bio Dilutor streamlines serial dilutions and liquid handling by reducing times and labor required. When diluting, it avoids diluent contamination with an air bubble system that ensures handled samples won’t come in contact with diluents.
Precision: A precise stepper motor controls liquid dispensing in the Bio Dilutor.
Versatility: It can be programmed to match a large array of liquid dispensing and dilution needs. A commanding pedal is available to ease operation with the device.
Its liquid handling circuit can be easily disassembled for sterilization.
Aplication Scope
Both Bio Dilutor models are high precision liquid handling tools that can automate serial dilutions and small volume liquid dispensing (between 1µl and 10 ml). While highly recommended to perform serial dilutions, it can also be used to precisely fill containers with predefined solution volumes.
The Biodilutor Advanced enables labs to perform low volume gravimetric dilutions when connecting the device to balance. Once sample weight is measured, the instrument dispenses accurate amounts of liquid according to its weight. The advanced model also includes a controller keyboard that eases device programming.
Both models can connected to a printer in order to print records of the dilutions and liquid dispensing that take place.
How to continue procesing diluted samples
Initial sample dilution takes place inside sterile bags, samples are placed in Portabag holders while awaiting to be homogenized in Masticator blenders. Once homogenized, aliquots can be serially diluted using the Bio Dilutor. The Eddy Jet 2 spiral plater is used in order to reduce the amount of plates that are processed, offering a threefold decimal dilution counting range in a single plate. Following incubation, plates are automatically counted and fed with the Plate Handler or automatically counted and manually fed with the SphereFlash®.
