A manual workflow for nucleic acid extraction is a heavy burden for laboratory, the capability of a labor would work for two or three hours and be tired after that, meanwhile the manual errors might happen unconsciously until the missed results are defined after exhaustedly several repeats, an automatic extractor is a good solution to replace labor, but the process of nucleic acid extraction contains a lot of tedious steps, most of the automatic extractor cannot have enough functions to meet the tedious steps of the nucleic acid extraction, they still need labor to learn and complement the shortages of automation such as for liquid handling, pre-thermolysis, or/and tedious worktable preparation, those labor-intensive extractors are not good choice.

Nothing is left for labor, LabTurbo is a perfect automatic extractor, its functions cover all of the tedious steps of nucleic acid extraction from sample lysis to product elution, labor is not needed at all, and meanwhile, LabTurbo offers a lot of additionally automatic functions for pre- and post-extraction to save labor. The transfer of sample to the tube for automation starting or storage backup is a labor-intensive work; LabTurbo can do this work by its smart liquid handling function. The tedious preparation of worktable, e.g. putting consumables one by one, is not needed for LabTurbo; it is simplified with strip or plate consumables, and moreover, LabTurbo has a reagent auto-vending system; it is not needed to prepare the reagents run by run. LabTurbo will do auto-clean and auto-recovery after extraction. LabTurbo is a truly perfect automatic nucleic acid extractor, all procedures are executed automatically and self-monitored by its own self, and it is also easy to learn and easy to operate, it will not cause a problem for laboratory even if staff handover happen.

The nucleic acid extraction is one of the steps for sample assay and it is a very time-consuming work, most of the laboratories hope to finish it in one or two hours or less. An experienced staff can speed it up in the expected time for 20 to 30 samples per day, but the manual errors, limited-capacity, and staff administrations are under black. There are a lot of automatic extractors in the market, but most of the extractors are jammed-machines that contain one or two or three or all of problems: 1. the capacity of an extractor is not enough, most of the low throughput extractors work 12 - 32 samples per run, it will take two or three or more runs to process all of the sample if the samples over 32, the transition between run and run is a time-consuming and staff have to stand-by; The second problem is the tedious worktable preparation, most of the low throughput extractors are designed to prepare worktable with plastic consumables one by one, e.g. a 12 capacity extractor, the staff have to put 12 samples, 12 elution tubes, 12 or 24 tips (plungers), 12 reagent cartridges¡Ketc. it take 48 actions and 20 minutes at least for worktable preparation for 12 samples, so it will take 40 minutes for 24 samples and 80 minutes for 48 samples, the time for worktable preparation is more than for extraction; The third problem is the slow extraction; some of extractors work 12 samples taking 90 minutes.

LabTurbo is a perfect automatic extractor; it has several models with different capacities to meet the demand of different throughputs, meanwhile, it speed up all of the procedures for nucleic acid extraction and takes as less as 10 minutes for worktable preparation by using strip or plate consumables and reagent auto-vending system, and the worktable is cleaned and recovered by itself after extraction. For some laboratories, it also can be used for sample transfer directly from primary tube to starting tube in 10 minutes or less, it also can be used for reaction (PCR) setup in 10 minutes or less. The summary of the run capacity and time of different models are as below:

• LabTurbo 48 compact system processes 1 up to 48 samples in 90 minutes.
• LabTurbo 96 standard system processes 12 up to 96 samples in 60 minutes.
• LabTurbo 496 system processes 96 up to 384 samples in 150 minutes.
• LabTurbo reaction setup system prepares 96 reactions in 10 minutes.

You can choose the proper model to match with the sample number to minimize the run number and meet the timing that you want.

One of the most challenges for nucleic acid extraction is to get the accurate result. Nucleic acid extraction contains many tedious steps in the process of nucleic acid extraction; meanwhile, the chemistry will dramatically affect the extraction performances, so it often happen the problems such as low yield, less sensitivity, and cross contamination. In order to get the best quality of extraction, an experienced staff or perfect extractor is absolutely necessary. Unfortunately, it is difficult to keep an experienced staff for bored extraction; the handover of staff is often, and most of the extractors are not reliable; they do not act its actions elegantly to meet the demand of the tedious steps in the process of extraction, their performances cannot meet the quality demand.

LabTurbo is a perfect automatic extractor for accuracy nucleic acid extraction; it has been optimized between hardware, protocol, and chemistry to completely match with the demands of tedious steps in the nucleic acid extraction. LabTurbo, by using innovative vacuum membrane column chemistry and technology, can effectively remove the impurities in the sample and get the maximum yield of nucleic acid and ultra-sensitivity on assay, this enable LabTurbo can work for wide-range of sample types including dirty and sticky samples. The precise operation of liquid handling of LabTurbo can avoid happening cross contamination. LabTurbo is flexible for starting material, the sensitivity can be effectively increased by increasing the sample volume and decreasing the elution volume to get higher concentration of target nucleic acid, LabTurbo can be loaded up to 1 ml or 100 mg of samples and elution volume reduced down to 60 µl or less. LabTurbo is the perfect automatic extractor in the world to offer an unparallel accuracy of nucleic acid extraction.
