Description
Technical field
The utility model belongs to metering device, relates to a kind of metering sampler, particularly relates to a kind of fermentation with aseptic metering sampler, goes for various liquid taken amount, be particularly useful for the aseptic taken amount sample that ferments.
Background technology
Biological fermentation is the direction that research is awfully hot at present, during the fermentation, the sample fermenting is needed to carry out index determining, need from bottom or top sample during general mensuration, this sampling mode causes a large amount of sample waste, impact is caused on cost keeping and sample concentration simultaneously, be unfavorable for continuing fermentation and optimizing.There is various taken amount device on the market at present, mostly may be used to the taken amount of the liquid such as medicine and reagent, but not yet there is the taken amount device for fermentation industry at present, most employing directly pulls the mode reducing air pressure and suck with piston, direct contact or need vessel be opened, require stricter fermentation industry to aseptic technique, this mode can cause microbiological contamination or mix impurity.Therefore, a kind of fermentation of development, with aseptic metering sampler, can address this problem.
Summary of the invention
The purpose of this utility model is to provide the aseptic metering sampler of a kind of fermentation, be made up of sealing cover 1, first conduit 2, graduated cylinder 4, second conduit 5, first switch 6, second switch 7, the 3rd conduit 8, piston 10 and syringe 11, first conduit 2 connects sealing cover 1 and graduated cylinder 4, between the first switch 6 is set, second conduit 5 connects graduated cylinder 4 and syringe 11, connects the 3rd conduit 8, and arrange second switch 7 below graduated cylinder 4, graduated cylinder 4 with a scale 3, piston 10 is placed in syringe 11 the other end.
Sealing cover 1 is fitted mutually with fermentor tank upper feeding equipment mouth.
Shaking hands to pull up and down by piston 10 to make the change of the air pressure inside syringe 1 diminish greatly, with this, liquid is sucked sucking-off.
During use, existing by after this gauger switch Close All, at being positioned over 121 DEG C, high pressure moist heat sterilization 15-20 minute, is connected to the apparatus for feeding mouth on fermentor tank, fixes cylindrical shell 4 by sealing cover 1 after taking-up, uses after fermentation ullage disappears real disappearing.When needing sampling, open switch 6, closing switch 7, pull piston 10 up and down, stop to the sampling amount scale marks 9 needed, sample liquid enters cylindrical shell 4 along with conduit 2, to corresponding scale marks 3, then closing switch 6, open switch 7, promote piston 10, sampling liquid flows out to corresponding container from conduit 8, is used in reference to target mensuration etc.
The mode that the gauger that the utility model provides adopts graduated cylinder and piston to be separated, simultaneously trip switch, isolated tank and extraneous contact, draw the liquid sample of corresponding measurement.The utility model is simple to operate, practical, is applicable to various liquid taken amount, is particularly useful for the aseptic taken amount sample that ferments.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is further described in conjunction with the accompanying drawings and embodiments.
embodiment 1
The purpose of this utility model is to provide the aseptic metering sampler of a kind of fermentation, be made up of sealing cover 1, first conduit 2, graduated cylinder 4, second conduit 5, first switch 6, second switch 7, the 3rd conduit 8, piston 10 and syringe 11, first conduit 2 connects sealing cover 1 and graduated cylinder 4, between the first switch 6 is set, second conduit 5 connects graduated cylinder 4 and syringe 11, connects the 3rd conduit 8, and arrange second switch 7 below graduated cylinder 4, graduated cylinder 4 with a scale 3, piston 10 is placed in syringe 11 the other end.Sealing cover 1 is fitted mutually with fermentor tank upper feeding equipment mouth.
Shaking hands to pull up and down by piston 10 to make the change of the air pressure inside syringe 1 diminish greatly, with this, liquid is sucked sucking-off.
During use, existing by after this gauger switch Close All, at being positioned over 121 DEG C, high pressure moist heat sterilization 15-20 minute, is connected to the apparatus for feeding mouth on fermentor tank, fixes cylindrical shell 4 by sealing cover 1 after taking-up, uses after fermentation ullage disappears real disappearing.When needing sampling, open switch 6, closing switch 7, pull piston 10 up and down, stop to the sampling amount scale marks 9 needed, sample liquid enters cylindrical shell 4 along with conduit 2, to corresponding scale marks 3, then closing switch 6, open switch 7, promote piston 10, sampling liquid flows out to corresponding container from conduit 8, is used in reference to target mensuration etc.
embodiment 2
The demarcation of sampling scale.Open switch 6, closing switch 7, pull piston 10 to corresponding scale, record scale marks 9, adjust the position of switch 7, with the good cylinder scale line 3 of tense marker, make it consistent.Closing switch 6 again, opens switch 7, promotes piston 10, and sampling liquid flows out to corresponding container from conduit 8, and consumption tolerance gets liquid actual volume, goes out to have marked volume digital at piston 10 and graduated cylinder 4 scale marks 3 simultaneously.Every sub-sampling, only needs to be sampled to scale marks place.
embodiment 3
Cellulase 50L liquid fermenting experiment sampling.Before upper tank, after this gauger switch Close All, at being positioned over 121 DEG C, high pressure moist heat sterilization 15-20 minute, after taking-up, sealing cover 1 is connected to the reserved opening position on fermentor tank, cylindrical shell 4 is fixed, and uses after fermentation ullage disappears real disappearing.Every day samples twice, and primary sample 50ml is used for enzyme and lives, and the index determinings such as pH, during use, directly open switch 6, closing switch 7, stops after pulling the scale filling in 10 to 50ml while still alive.Closing switch 6 again, opens switch 7, and promote piston 10, enzyme liquid flows out to beaker from conduit 8, is used in reference to target mensuration etc.
