Description
Technical field
The utility model relates to a kind of analytical and testing instrument technical fields, more particularly to a kind of colorimetric for placing cuvette
Ware slot.
Background technique
Cuvette is made by colorless and transparent, corrosion resistant glass or quartz, for containing detected solution and reference solution,
Cuvette is cylindrical body, and different depending on the application, thickness is also different, and cuvette is mounted in the cuvette slot of test equipment, is matched
Such as spectrophotometer in the spectrum analysis of set, the analysis of blood linear protein, Particle Size Analyzer etc. is quantitative through row to substance, and qualitative analysis is wide
General to be used for chemical industry, metallurgy, food is medical, the industries such as aquatic products, department and universities and colleges, and scientific research test is chemically examined practical.Entire mistake
It is photoelectricity input that journey is shone by lamp holder, and the fluid to be measured light transmittance that reagent is added changes, and the inductor of light-measuring hole is
Optical signal is switched to electric signal and recorded by photoelectric yield.Existing colorimetric slot device has the following problems, lamp holder and major trough body
Using bonding, light source not easy to overhaul；Major trough body does not have position limiting structure, and to guarantee that cuvette is placed steadily, detection, which can exist, to be missed
Difference；The more circular holes of light-measuring hole, and inductor be it is rectangular, carry tabula rasa segment space there are reflection source, exist to testing result and interfere,
There is no waterproof construction, is easy to make the load tabula rasa dampness where inductor.
Utility model content
In view of the deficiency of the prior art, it the purpose of this utility model is to provide a kind of new reaction, improves
Measuring accuracy and shorten the testing time, is easy to overhaul, the features such as waterproof.
The purpose is achieved through the following technical solutions:
Cuvette slot overall appearance is octagon, each side of octagon on the lower in the localities there are three hole,
The middle smaller obstructed hole in macropore two sides is screw thread hole, and when fixing circuit board is used, and there are two types of form, common features for intermediate macropore
It is all sunk-in through-opening, deep gouge is relatively large in diameter and deep hole is to place photronic, and deep gouge diameter is smaller and what depth was shallower is to put
Set electroluminescent lamp.
Eight sides of cuvette slot are separately installed with photocell and electroluminescent lamp, and all photocells and electroluminescent lamp are in same height
Degree, and the center of octagon solid is crossed in the axle center of photocell and electroluminescent lamp, and photocell and electroluminescent lamp are to correspond to close
System, it is A, B, C, D, E, F, G, H that eight faces numbers respectively, wherein be that photronic face numbers being B, C, D, G, H, remaining number is
Electroluminescent lamp, photocell and electroluminescent lamp corresponding relationship are as follows: A-E, B-F, C-G, D-H, totally four groups.
Electroluminescent lamp welds on circuit boards, and the light color of sending is sent out by process control according to different chemical elements are detected
Different light out, circuit board have screw to be fixed on eight sides.
Cuvette groove center is cylindrical body thin walled cavity, and there are two adjacent support bars in cylindrical body inside cavity side, with
The flexible buckle in the corresponding side of support bar, their collective effects reduce the contact area with cuvette, and play clamping colorimetric
The effect of ware.
There are four countersunk head screw holes for cuvette trench bottom, use when fixing other components.
The utility model has the advantage that
Cuvette slot can issue four kinds of different light simultaneously, and detection range is more；
Cuvette slot uses regular octahedron moulding, and space layout is compact.
