The transfer pipette protection device comprises a fixed outer ring (1), a sliding inner ring (3), an inner ring upper sliding rail (2), an inner ring lower sliding rail (11) and a transfer pipette arrangement table (7); when the inner ring (3) slides to a closed position, the inner ring (3) and the fixed outer ring (1) form a closed cylinder; the inner ring upper sliding rail (2) is arranged at the upper end of the inner surface of the fixed outer ring (1); the inner ring lower sliding rail (11) is arranged at the lower end of the inner surface of the fixed outer ring (11); the outer ring (1) is fixed on the tabletop of the transfer pipette arrangement table (7); a liquid flow guide hole (6) is formed in the tabletop; a detachable liquid collection basin (8) is arranged in the transfer pipette arrangement table (7); and seeping liquid is collected in the detachable liquid collection basin (8). The transfer pipette protection device is used for supplying various protection measures to a transfer pipette in the chemical laboratory, so that the problem that the transfer pipette is polluted by dust and various acids, organic matter gas and the like in the laboratory can be effectively solved; the phenomenon that the transfer pipette topples over and is crushed can be well avoided.
Description
Technical field
This application of installation, in chemical laboratory, specifically belongs to chemical experiment equipment protective device.
Background technology
Pipette belongs to conventional chemical experiment equipment, all indispensable in any chemical laboratory, but at present chemical laboratory does not have that special pipette is anti-pollution, anti-tipping apparatus, and multiplex gauze, common cloth etc. are interim to be covered, and does not have antipollution effect.Pipette is placed on pipet stand easily by dust and all kinds of gaseous contamination, easily topples over.
Therefore, be badly in need of a kind of good protector, in the good contaminated while of protection pipette, also can be convenient to the use of pipette.
Utility model content
This is tested novel object and is: a kind of pipette protector of special use is provided, avoids pipette contaminated and topple over, and safety easy to use.
This experiment is novel to be specially: a kind of chemical laboratory pipette protector, wherein, comprising:
Fixing outer ring, outer ring is strip, vertically places, its level cross-sectionn is semicircle;
The inner ring that can slide, identical with outer loop-shaped, inner ring is also vertically placed for strip, level cross-sectionn is semicircle, inner ring level cross-sectionn radius is less than level cross-sectionn, outer ring radius, when inner ring slides into closing position, forms a closed cylinder with fixing outer ring;
Slide rail on inner ring, is arranged on fixedly inner surface upper end;
Inner ring glidepath, is arranged on fixedly inner surface lower end;
Pipet stand mounting table, outer ring is fixed on the table top of pipet stand mounting table, is provided with liquid guide flow hole on table top;
Dismountable liquid collection bath is set in pipet stand mounting table, under the liquid collection that oozes at this, locate.
A kind of chemical laboratory pipette protector as above, wherein, also comprises:
Be arranged at the inner ring slide handle of inner ring outer surface, promote inner ring and slide;
Sealing strip, is arranged at the inner side, vertical edge of both sides, outer ring, when inner ring is closed, for the sealing gap between inner ring and outer ring;
Be arranged at the liquid collection bath switch handle of liquid collection bath;
The sponge arranging in liquid collection bath, the liquid oozing under described in spongy absorbing.
Effect of the present utility model is: the utility model can provide various protection for chemical laboratory pipette, can effectively solve the problem that pipette is polluted by all kinds of acid and organic gas in dust, laboratory etc., the situations such as pipette is toppled over, fragmentation that can prevent preferably occur.
Accompanying drawing explanation
Fig. 1 is pipet stand protective cover structural representation;
Fig. 2 is pipette protective cover cutaway view;
Fig. 3 is pipette protective cover base plane figure;
Fig. 4 is pipette protective cover base profile.
Wherein, 1, fixing outer ring, 2, slide rail on inner ring, 3, inner ring slidably, 4, inner ring slide handle, 5, sealing strip, 6, liquid guide flow hole, 7, pipet stand mounting table, 8, liquid collection bath, 9, liquid collection bath switch handle, 10, liquid absorption sponge, 11, inner ring glidepath.
The specific embodiment
Below, with the specific embodiment, the utility model is described further by reference to the accompanying drawings.
This device is to develop in conjunction with the actual conditions of laboratory pipette use, and material therefor is transparent organic glass.
As shown in Figure 1, device described in the present embodiment has 11 building blocks, specifically comprises with lower member.
Fixing outer ring 1, outer ring 1 is strip, vertically places, its level cross-sectionn is semicircle;
The inner ring 3 that can slide, identical with outer ring 1 shape, inner ring 3 is also vertically placed for strip, level cross-sectionn is semicircle, inner ring 3 level cross-sectionn radiuses are less than outer ring 1 level cross-sectionn radius, when inner ring 3 slides into closing position, form a closed cylinder with fixing outer ring 1, in Fig. 1, represented the state of inner ring 3 semi-closed;
On inner ring, slide rail 2, are arranged on fixedly outer ring 1 upper inner, facilitate inner ring 3 closures and switch;
Inner ring glidepath 11, is arranged on fixedly 1 inner surface lower end, outer ring, facilitates inner ring 3 closures and switch;
Inner ring slide handle 4, promotes inner ring 3 and slides;
Sealing strip 5, is arranged at the inner side, vertical edge of 1 both sides, outer ring, when inner ring 3 is closed, for the sealing gap between inner ring 3 and outer ring 1, prevents that dust etc. from entering;
Pipet stand mounting table 7, outer ring 1 is fixed on the table top of pipet stand mounting table 7, is provided with liquid guide flow hole 6 on table top, in the pipette after convenient cleaning, under residual liquid, oozes;
Liquid collection bath 8 is set in pipet stand mounting table 7, under the liquid collection that oozes at this, locate, this pond is demountable; Liquid collection bath switch handle 9, facilitates taking-up and the replacing of liquid collection bath 8; The sponge 10 that absorbs liquid is set in liquid collection bath 8, and sponge 10 is removable consumptive material.
So, when pipette is placed, first by inner ring slide handle 4 slip inner rings 3, arrive full open position, then pipette is put into, then by inner ring 3 closures; When taking out, otherwise.Both easy to use, can prevent again the pollution of pipette.
Above embodiment of the present utility model is explained in detail, above-mentioned embodiment is only optimum embodiment of the present utility model, but the utility model is not limited to above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
