It is a common task in the lab to periodically sample a reactor or a fermenter to obtain information about reaction kinetic, completion and have a tangible representation of intermediate states of a dynamic process. This usually done manually with pipettes or syringes, using stopwatch to measure time and requires to be in the lab during the entire process.
With Samplify it can be done in automated mode. When an automated sampling process is used it increases accuracy, safety, and productivity. It reduces potential samples cross contamination, and exposure of the reaction mixture to oxygen or moisture, when anaerobic or moisture free conditions are required.
Based on a proprietary alpha/beta mechanical configuration, Alltesta Miniature Autosampler and patent pending sample probe offers affordable and reliable automation for many analytical and liquid-handling applications.
Small controllable volume of sample can be programmed and precisely removed from the enclosed or open system. The sample will then be transferred to a vial with inert solvent with measured volume to create a controllable dilution factor.
A quench solution can be automatically preloaded in each vial to provide termination of reaction or biological process, and preserve sample content in the time of probing.
In order to effectively mix samples with diluents or quenching reagents a shaking capability of the autosampler tray can be initiated after each sample cycle.
PC based software allows quick, but flexible, setup of the sampling experiment. Several preloaded methods can be quickly adapted to a particular needs of the user.
For temperature sensitive samples the entire autosampler can be placed in the temperature controlled environment.
The device small size allow to place it close to the reactor and use short connection lines to minimize dispersion. Also a small cooler can be used to keep samples in cold conditions after they are collected.
