Description

Constant volume bottle for experiments

Technical Field

The utility model belongs to the experimental device field, concretely relates to constant volume bottle for experiments.

Background

The washing bottle is basically configured in a laboratory, has a structure of an elbow tubule inserted on a plastic bottle, and has wide application, but the existing washing bottle only has specification selection and no functional selection; in the experimental process, the bottle washing has multiple purposes including solution constant volume and the like, but cannot meet the requirement of accurate operation of the experiment.

In the process of the constant volume experiment, other instruments (such as a rubber head dropper and the like) are required to be matched for operation besides bottle washing, so that the steps are multiple and mistakes are easy to make.

Disclosure of Invention

The utility model aims at providing a constant volume bottle for experiments, the constant volume experiment can be accomplished to the exclusive use, need not other equipment and assists, and has the advantage that the precision is high.

The utility model adopts the technical proposal that:

the utility model provides a constant volume bottle for experiments, is including the bottle that has the bottle lid, inserts on the bottle lid and is equipped with the tubule that leads to the bottle bottom, and the part that this tubule exposes the bottle lid is curved form, and the within range from flexion to tubule tip delivery port distributes in proper order has several bulb type pipe, does benefit to the backward flow and the storage of trace liquid, can accurate control liquid outflow in the bottle.

Furthermore, the diameter of the water outlet is 0.5-1 mm, which is smaller than the diameter of the water outlet of a common wash bottle, so that the outflow can be well controlled.

Furthermore, the bending part is a folded pipe, and the curvature of the bending part is conveniently adjusted by adopting a folded principle so as to adjust the angle of the water outlet.

Furthermore, the number of the spherical pipes is five, and the diameter of each spherical pipe is 1-5 cm.

The utility model has the advantages that:

1. in the process of a constant volume experiment, the spherical pipe is beneficial to the backflow and storage of trace liquid, the flow speed and flow rate of the liquid in the bottle can be well controlled when the liquid flows out, and the accurate constant volume is realized; and to the ordinary outlet pipe that does not have the bulb type pipe, when the extrusion bottle, the uncontrollable play of liquid in the bottle, flow control needs the operator to control the size of extrusion force with the hand, is difficult to control comparatively accurate flow.

2. The flexion adopts the fold principle, conveniently controls the direction of delivery port, simultaneously, in the constant volume experiment, except this constant volume bottle, need not the collocation use of other instruments, reduces the error rate.

Drawings

FIG. 1 is a sectional view of the overall structure of the present invention;

in the figure, 1, a water outlet, 2, a spherical pipe, 3, a bending part, 4, a bottle cap, 5, a bottle body, 6 and a thin pipe.

Detailed Description

As shown in figure 1, the constant volume bottle for experiments comprises a bottle body 5 with a bottle cap 4, a thin tube 6 communicated with the bottom of the bottle is inserted into the bottle cap 4, the part of the thin tube 6 exposed out of the bottle cap 4 is in a bent shape, five spherical tubes 2 with the diameter of 3cm are sequentially distributed in the range from a bent part 3 to a water outlet 1 at the end part of the thin tube, backflow and storage of trace liquid are facilitated, and the liquid outflow in the bottle can be accurately controlled.

The diameter of the water outlet 1 is 0.5-1 mm, and is smaller than the diameter of the water outlet of a common wash bottle, so that the outflow quantity can be well controlled.

The bending part 3 is a folded pipe, and the curvature of the bending part is conveniently adjusted by adopting a folded principle so as to adjust the angle of the water outlet.

Claims (4)
