Description
Technical field
The utility model is related to biochip dehydration technique field, especially a kind of devices for glass-chip dehydration.
Background technology
Protein chip, to ensure the low background of chip, needs to pass through cleaning before immune response, particularly last colour developing
Sample and reagent extra on chip are removed, but after cleaning, it is also necessary to remaining moisture on chip is removed, to ensure chip
Background homogeneity reduces noise, avoids influencing testing result.
The prior art is got rid of liquid or is done with wind using centrifugation technique rotation.Since air drying process leaves irregular washmarking
Cause background inhomogenous, influence testing result, in addition, it is a slow process to air-dry, albumen may be caused impacted, it is also possible to
It can lead to fluorescent quenching and then influence signal scheme, so that final detection result can be affected, so with wind dry doubling not
It is common.Research staff often gets rid of liquid with centrifugal device rotation, i.e., dries the water on slide by way of centrifugation.
At present, on the market there are two types of the common devices for slide centrifugation, one kind is with chip centrifuge tube, chip centrifugation
Pipe borrows the centrifuge tube of present 50mL specifications, and two opposite grooves of 180 degree are designed in centrifuge tube, and size is just inserted
Enter a glass matrix chip (750~786mm × 245~254mm × 11-16mm).Moisture during centrifugation on chip is from slide
On be thrown to chip centrifugation bottom of the tube.Can borrow in this way the centrifuge tube of existing 50mL specifications centrifugal device (centrifugal rotor and
Centrifuge), it does not need to additionally be designed.
Chip centrifuge tube has 3 shortcomings：(1) it is the centrifuge tube of a 50mL specification since centrifuge tube specification limits
A piece of chip can only be once packed into, flux is not high, and the number of chips centrifuged every time is limited；
(2) chip is to place vertically, and the moisture content on chip will get rid of, and needs the length that the distance flowed through is oblong chips
Spend 750~786mm, this, thus may be dry in midway apart from long, forms higher background, cause when detecting compared with
Big noise；
(3) heart is separated water into bottom of the tube is centrifuged by centrifugation, when taking out chip, moisture is easily contacted again chip,
Drying is caused to be not thorough, influences chip results.
Second for slide centrifugation device be centrifugal device design exclusively for chip, including special centrifuge with
Mating rotor, support chip place equipment.Its shortcoming includes：
(1) because special design, price is costly；
(2) although higher than the flux of chip centrifuge tube, flux is still not high enough, and such as brilliant core SlideWasher chips are washed
Dry instrument is once only capable of 8 sheet glass chips of centrifugation；
(3) chip is placed using vertical, and the moisture content on chip will get rid of, and it is oblong chips to need the distance flowed through
750~786mm of length, this, thus may be dry in midway apart from long, forms higher background, causes when detecting
Larger noise.
Utility model content
It, can be fast the purpose of the utility model is to overcome one kind is provided in place of above-mentioned the deficiencies in the prior art based on this
Speed, the device for thoroughly sloughing moisture on chip are dehydrated glass-chip using the device, and the advantage for having flux high takes off
Glass-chip noise after water is extremely low, even without noise.
To achieve the above object, the technical solution that the utility model is taken is：For glass-chip dehydration device, including
Glass-chip box body, the first box cover, blotting paper, filling block and the second box cover, second box cover is equipped with upward groove, described
Be equipped with blotting paper in groove, first box cover is equipped with window, and the blotting paper is close to the window, the box body and
First box cover matches, and gap is equipped between first box cover and second box cover, and the filling block is set on described
In gap.Box body is located at the top of the first box cover as a result, and box body is interior equipped with multiple glass-chips, on the glass-chip after cleaning
It is remaining it is water stain in centrifugal process to the first box cover flow, then absorbed by blotting paper, quickly can thoroughly slough glass
Moisture on chip；Filling block can ensure that box body will not be moved with the first box cover in the second box cover, and glass-chip is avoided to exist
Fragmentation in centrifugal process.
Preferably, the blotting paper is dry filter paper.
Preferably, the card slot of at least 15 glass-chips is equipped in the glass-chip box body.As a result, relative to existing
Chip centrifugal device, the centrifugation flux of the device of the application significantly improve, and can significantly improve the dehydration efficiency of glass-chip；Root
According to needs, the quantity of the card slot of glass-chip can be adjusted.Wherein, 25 glass-chips are equipped in more preferable glass-chip box body
Card slot.
Preferably, the filling block is silica gel block.Silica gel block has certain elasticity as a result, using the device of the application
Glass-chip is dehydrated, when centrifugal device breaks down, flexible silica gel block can play the role of buffering collision of closed, keep away
Exempt from glass-chip fragmentation.
Preferably, the overhead height of the filling block is identical with the bottom level of the box body.As a result, when the dress of the application
It puts when being centrifuged in ELISA Plate rotor, since the overhead height of filling block is identical with the bottom level of the box body, in rotor
Middle distribution of weight is uniform, also opposite to the operating on centrifugal force of glass-chip to mitigate, can be to avoid glass-chip due to unbalance stress
And fragmentation.
Preferably, the distance of 1~8mm is equipped between the edge of the edge of the window and first box cover.It should say
Bright, when distance is less than 1mm between the edge of the edge of window and first box cover, glass-chip is possible to centrifuging
In the process, deviate from from window；And when distance is more than 8mm between the edge of the edge of window and first box cover, part is remote
The moisture that chip from window is taken off may remain in chip bottom, it is impossible to it is absorbed immediately by blotting paper, it is larger so as to generate
Noise.
Preferably, the distance of 4mm is equipped between the edge of the edge of the window and first box cover.Work as window as a result,
Mouthful edge and first box cover edge between equipped with 4mm apart from when, glass-chip will not be in centrifugal process from window
Mouth abjection, blotting paper can also will be far from the moisture absorption that the chip of window is taken off immediately.
It is highly preferred that the height of the box body is 248~261mm.The chip in glass-chip box body is traverse as a result,
, then moisture generally moves in centrifugal process on the short side direction of rectangular chip, and the width of short side is 245~
254mm when the height of box body is 248~261mm, can accommodate the chip of traverse, meanwhile, it can be to avoid leaving larger sky
Between so that chip shakes in box body.
In conclusion the beneficial effects of the utility model are：
(1) the chip dehydration device of the application washes dry instrument compared to chip centrifuge tube, dedicated chip, can once centrifuge 50
Piece, flux significantly improve；In addition, since glass-chip box space is big, close-packed arrays are not needed between chip, are more advantageous to water
Divide and be detached from chip surface, reaching reduces background noise purpose；
(2) the box body chips of the application use traverse, and it is rectangular that the moisture on chip, which gets rid of the distance that needs flow through,
The width (i.e. 245~254mm) of shape chip, this distance are shorter than the distance of water flow on the chip placed vertically, can effectively drop
Low noise.
