Description

A kind of sample injection bottle improving the rate of recovery

Technical field

The utility model relates to sample injection bottle fields, more specifically, it relates to a kind of sample injection bottle for improving the rate of recovery.

Background technique

Sample injection bottle is usually for carrying out the instrument that chromatography experiment fashionable dress takes sample to be tested to substance.Sample injection bottle generally by Glass hydrolytic or borosilicate are made.Sample injection bottle used in laboratory is usually flat sample injection bottle.

Flat sample introduction bottle structure offers bottleneck on body 1 as shown in Figure 1, generally comprise body 1, bottleneck 2 and bottle cap 6 2.Screw thread is provided on the lateral wall of bottleneck 2, bottle cap 6 and threaded connection are engaging in bottleneck 2.Body 1 is usually flat cylindric. Flat sample injection bottle can be put after dress takes sample to be tested it is spare on the table, do not need place sample injection bottle shelf.

But flat sample injection bottle bottom is plane or cambered surface, remaining sample can be laid on sample injection bottle bottom in sample injection bottle Portion, laying area is big, so that liquid level is lower, can not submerge the syringe needle of sample introduction needle, remaining sample can not pass through sample introduction needle It takes out, causes the waste of reagent.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of sample introductions for improving the rate of recovery Bottle flows back into groove by concentrating the sample for being retained in sample injection bottle bottom in body bottom setting groove and rounded corner In can be drawn by sample introduction needle, solve the problems, such as that remaining sample can not take out wasting in sample injection bottle.

To achieve the above object, the utility model provides following technical solution:

A kind of sample injection bottle improving the rate of recovery, including body offer bottleneck on the body, and the body includes bottom of bottle And bottle wall, the bottle wall inner sidewall and bottom of bottle inner sidewall junction are set as arc round-corner transition, the bottom of bottle inner sidewall Center opens up fluted, and the recess sidewall and the bottom of bottle junction are set as rounded corner.

By using above-mentioned technical proposal, when the sample in sample injection bottle remains in bottom, sample is flowed by rounded corner In groove, bottle wall inner sidewall and bottom of bottle inner sidewall junction will not be remained in, so that the residual sample of sample injection bottle bottom is ok It flows into groove, groove setting is at bottom of bottle center, and ruler diameter is less than the diameter of body, and groove has certain depth, sample introduction needle When being sampled, the syringe needle of sample introduction needle can submerge sample liquid level in a groove hereinafter, sample introduction needle can be by the examination in groove Sample is drawn out.

Further, firm layer is provided on the bottom of bottle lateral wall, the firm layer and the body are integrally manufactured.

By using above-mentioned technical proposal, after sample is largely used, sample injection bottle quality itself lightens, and firm layer can To increase the weight of sample injection bottle bottom, so that sample bottle is not easy to be toppled over by external force.

Further, the firm layer is provided with the striped being parallel to each other far from the side inside the body.

By using above-mentioned technical proposal, striped can increase the coefficient of friction of firm layer, increase firm layer and desktop it Between friction so that sample injection bottle is not easy to slide on the table, increase stability.

Further, the bottleneck is provided with retainer plate, and the retainer plate inner sidewall is provided with internal screw thread, the retainer plate It is threadedly coupled fixation with the external screw thread on the bottleneck lateral wall, convex block, the length of the convex block are provided on the retainer plate Direction is vertical with the body axis.

By using above-mentioned technical proposal, convex block is fastened on bottleneck two sides by retainer plate and whorl of bottleneck, when making It can be by crawl convex block come sample injection bottle of taking with operator when sample injection bottle；The vertical body axis of convex block length direction can increase convex The contact area of block and hand, so that it is more convenient when making to take and stable to increase friction；When sample injection bottle when not in use, then lead to It crosses rotation retainer plate and removes retainer plate from bottleneck, then rotate sample injection bottle bottle cap, be threaded in bottleneck, it is easy to operate Fast.

Further, one layer of rubber layer is provided on the lug surface.

By using above-mentioned technical proposal, rubber layer can increase the coefficient of friction of lug surface, when operator take it is convex When block, the friction between hand and convex block is bigger, gets more surely, does not fall off.

Further, the bottle wall is set as inner layer wall and outer wall, and the inner layer wall of smooth abrasion-proof glass by being made Inner layer wall, the outer wall outer wall made of hard plastic, the inner layer wall is fixedly connected with the outer wall, described Storage inner cavity is formed between inner layer wall and the outer wall, is stored in inner cavity and is provided with water layer.

By using above-mentioned technical proposal, inner layer wall is made of smooth abrasion-proof glass, can reduce sample introduction needle and protrudes into sample introduction Friction when bottle to sample injection bottle inner layer wall pollutes sample so that the syringe needle of sample introduction needle be avoided to scratch inner layer wall；Outer wall is by hard Matter plastics are made, can to avoid when sample injection bottle occur slight impact when and it is broken, keep sample injection bottle safer.Inner layer wall and outer Layer wall is separated by and is provided between inner layer wall and outer wall water layer, and when operator's hand is brought into sample bottle, the temperature of hand will not It is directly conducted into bottle by bottle wall, the specific heat capacity of water is big, can slow down the disengaging of heat, is more conducive to maintaining in sample injection bottle Portion's temperature is not greatly changed and influences chromatography.

Further, one layer of plastic sunscreen layer is coated on the outer wall.

By using above-mentioned technical proposal, there is light-exposed easy reaction or labile spy when filling the sample taken in sample injection bottle Property when, light shield layer can effectively stop light transmission to enter in sample injection bottle, so influence sample.

Further, the cell wall in the bottom of bottle along the groove offers spherical cavity, and water is full of in the spherical cavity.

Pass through ball when the syringe needle of sample introduction needle, which will be inserted into, carries out extraction sample in groove by using above-mentioned technical proposal Shape chamber observes the relative position of syringe needle and groove, and sample is carried out in groove to be more easier for the syringe needle of sample introduction needle to be inserted into It draws.

Compared with prior art, the utility model has the advantages that:

1, groove is opened up in sample injection bottle bottom of bottle by setting and sets rounding for sample injection bottle bottle wall and bottom of bottle junction Angle is concentrated remaining sample and is flowed back into groove, then taken out with sample introduction needle, and the waste of sample is reduced, Improve the rate of recovery；

2, by setting retainer plate and the convex block being connected on retainer plate, operator is led to when using sample injection bottle Crawl convex block is crossed to be brought into sample bottle, increases stability when taking sample injection bottle, prevents from sliding；

It 3, can be effectively by the water layer set body between inner layer wall, outer wall and inner layer wall and outer wall The temperature conduction of hand enters in sample injection bottle when hand being avoided to be brought into sample bottle, influences on the sample in sample injection bottle.
