Description
Technical field
The utility model relates to a kind of slipstream filter column combination purification devices of plural serial stage.
Background technology
In existing purification technique, slipstream filter post based on membrane separation technique utilizes the different filter membrane retaining aperture, realize the ultrafiltration to multiple solution and micro-filtration, be mainly used in: cell harvesting or washing, protein concentration, desalination, abstraction and purification, viral concentration or removal, the life science such as thalline or cell harvesting.Existing purification devices adopts single slipstream filter post to carry out sample treatment in compression pump pressurised driving mode usually, but this processing mode exists following drawback:
(1) when sample needs carry out gradient centrifugation or filter to collect different component, use single slipstream filter post purification devices process operability poor, need repeated collection, sample introduction, filtration, cause sample loss amount large;
(2) when collecting different component, due to complex operation step, the operating time is long, causes some easy degradable component loss, thus brings impact difficult to the appraisal to the accuracy of subsequent detection.
Utility model content
For above-mentioned deficiency, the utility model provides a kind of slipstream filter column combination purification devices of plural serial stage, this device leads to the filtration group that film retains the slipstream filter post formation that aperture reduces step by step, purifying filtered sample step by step, then different much filtrate is collected as required, realize single injected sampling, multistagely to leach, sample loss amount is little, and can continuous operation, effectively improve the treatment effeciency that single concentrates or filters, reduce the operating time, thus reduce the loss of the easy degradable component of sample, increase subsequent detection accuracy.
The utility model is realized by such technical scheme: a kind of slipstream filter column combination purification devices of plural serial stage, comprise at least two-stage slipstream filter post purification devices, every one-level slipstream filter post purification devices all comprises fluid reservoir, tube connector A, compression pump, tube connector B, doughnut membrane filtration post, concentrate return duct, filter liquor discharge pipe.The bottom of described fluid reservoir arranges a concentrate outlet, described fluid reservoir lower end is communicated with described compression pump entrance by described tube connector A, described compression pump outlet is communicated with the lower end of described doughnut membrane filtration post by described tube connector B, the upper end of described doughnut membrane filtration post is communicated with fluid reservoir by described concentrate return duct, described doughnut membrane filtration post upper end sidewall arranges a filtrate outlet, and this filtrate outlet is communicated with the fluid reservoir of next stage slipstream filter post purification devices by described filter liquor discharge pipe.
Further that the film of described doughnut membrane filtration post retains aperture and reduces step by step.
Be further that the concentrate outlet bottom described fluid reservoir connects a concentrate discharge pipe, it arranged an on-off valve A.
Further that described tube connector B arranges an on-off valve B.
Further that described concentrate return duct arranges a back pressure valve C.
Be further described tube connector B on-off valve B above sidewall on a pressure monitoring opening is set, pressure monitoring opening is arranged a Pressure gauge.
Owing to have employed said structure, the slipstream filter column combination purification devices of a kind of plural serial stage that the utility model provides, single injected sampling in the fluid reservoir of the first order, every one-level has the circulatory system of drive, can control separately, the film of doughnut membrane filtration post retains aperture and reduces step by step, arrange according to actual needs after film at different levels retains aperture and collect concentrate from concentrate discharge pipe at different levels, without the need to repeated collection, sample introduction and filtration, sample loss amount is little, and can continuous operation, the treatment effeciency that effective raising single concentrates or filters, reduce the operating time, thus reduce sample component loss, increase subsequent detection accuracy.
