But described lucite column jecket individual layer or bilayer.
Described upper and lower decorative cover is assembled to the two ends of described glass tube column, and by described tie-rod.
Described screw rod has 4-6 root, is positioned at described glass tube column peripheral, uniform assembling.
Described substrate portion comprises substrate, lower distributor, lower screen cloth, chromatography mouth, supporting leg etc.
Described substrate is greater than the maximum outside diameter of described upper and lower decorative cover.
Described lower distributor is on described substrate, and both connect by screw fastening.
Described lower screen cloth is positioned on lower distributor, and under glass tube column, three is by U-shaped sealing ring sealing.
Described foot-supporting frame has 4, and castor can be installed by foot, facilitates the movement of equipment.
This manual chromatographic column, comprises and can produce column cap part, glass tube column part and substrate portion.Described post head divides the column cap flange comprising and can produce, column cap support member, leading screw, lifting rod, and small rotary is taken turns, swiveling wheel, column cap hold-down ring, feed screw nut, upper chromatography mouth, distributor etc.; Described glass tube column part comprises lucite tube, upper and lower decorative cover, screw rod etc.; Described substrate portion comprises substrate, distributor, supporting leg etc.Described manual chromatographic column is characterized in that described column cap part can screw out by the rotary screw on the upper decorative cover of described column jecket part; Described column cap part also comprises the lifting rod in described leading screw inner chamber, and described lifting rod realizes promoting and declining by small rotary wheel; Especially, lifting and the decline of described lifting rod can impel the sealing hold-down ring of described column cap part realize the compression of sealing ring and unclamp, and then realize sealing and the depressurization of column cap.Described upper chromatography mouth passes from leading screw side, shortens stream, decreases corner or spot as yet untouched by a clean-up campaign.
Advantage of the present utility model is that described column cap can produce by the rotary screw on upper decorative cover; Small rotary can be relied on to take turns lifting for column cap sealing or decline lifting rod realizes; Upper chromatography pipeline passes from leading screw side, and stream is short, reduces corner or spot as yet untouched by a clean-up campaign.
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
