Abstract
The invention relates to a soaking cylinder for migration testing of food contact materials. The soaking cylinder comprises a cylinder body and a cover, wherein the upper end of the cylinder body is provided with an inner grinding opening, the cover is provided with an outer grinding opening, the cylinder body is provided with a glass tube, the upper end and the lower end of the glass tube are communicated with the cylinder body, scales for measuring the liquid level are formed on the glass tube, and the diameter of the glass tube is smaller than 0.5cm. The soaking cylinder designed by the invention can be used for directly reading the corresponding volumes at the beginning of the soaking and at the end of the soaking and accurately controlling the temperature and volume when the solution is heated, does not need to be transferred, wholly adopts a glass material, and has inertia to various soaking solutions, so that error cannot occur.
Description
Technical field
The present invention relates to a kind of immersion cylinder, particularly cylinder is soaked in a kind of food contact material migration test.
Background technology
During food contact material migration test, for complete immersion sample, glassware is adopted to soak sample, but, have following factor easily to cause larger metrical error when daily immersion:
1, test fluid often requires under 95 DEG C or 60 DEG C of conditions, this just needs to carry out preheat process to test fluid, if need to add fixing volume to after soak solution heating with traditional beaker, this just needs to shift with graduated cylinder etc., the temperature accurately controlling soak solution is difficult in transfer process, initial temperature disunity when causing each sample test, thus cause test error;
2, the experiment had will carry out 121 degree of high-temperature sterilizations, sometimes soaking conditions is 20% ethanol or 50% ethanolic solution, 60 DEG C are soaked 10 days, in immersion process, owing to adopting masking foil sealing, part solution easily volatilizees, last soak solution reduces more, even sample all cannot be flooded, cause result collimation poor, and test volume differs, easily introduce error;
3, soak and often adopt preservative film or masking foil sealing, these joint filling materials are easily dissolved by soak solution or corrode, and introduce error;
4, immersion will carry out stereometry to soak solution after terminating again, cannot shift clean completely, easily cause volumetric errors in transfer process.
Summary of the invention
The object of this invention is to provide and a kind ofly need not to shift, directly read the high food contact material migration test immersion cylinder of liquor capacity, accuracy.
The technical scheme realizing the object of the invention is as follows:
A kind of food contact material migration test is with soaking cylinder, comprise upper end and be provided with the cylinder body of interior ground and the lid with outer grinding port, described cylinder body arranges glass tube, described glass tube top and bottom are all communicated with cylinder body, described glass tube is provided with the scale measuring liquid level, described diameter glass tube is less than 0.5cm, and described glass tube exterior surface is provided with the plano-convex lens for amplifying reading.
After adopting said structure, the immersion cylinder of the present invention's design directly can read corresponding volume at the end of immersion starts and soaks, because diameter glass tube is less, concave meniscus can be seen clearly very accurately, thus reduce reading error, plano-convex lens is exaggerated scale registration, facilitate reading, the interior ground of cylinder body can be connected with the outer grinding port of lid is complete, prevents steam leakage, need not shift when solution heats, can accurately control temperature and volume, whole employing glass material, to the equal inertia of all kinds of soak solution, can not introduce error.
Preferably, conveniently uncap and identification lid, described lid is provided with the handle that can number.
Preferably, soak when cylinder is put together to prevent many covers and lid is mixed up, described handle is tied with line, and described handle is connected with glass tube by line.
Preferably, in order to pin-point reading, the diameter of described glass tube is 0.3cm.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
In figure: 1 is cylinder body, 2 is interior ground, and 3 is lid, and 4 is outer grinding port, and 5 is glass tube, and 6 is scale, and 7 is handle, and 8 is line, and 9 is plano-convex lens.
Embodiment
A kind of food contact material of the present invention migration test immersion cylinder comprises upper end and is provided with the cylinder body 1 of interior ground 2 and the lid 3 with outer grinding port 4 as shown in Figure 1, described cylinder body 1 arranges glass tube 5, described glass tube 5 top and bottom are all communicated with cylinder body 5, described glass tube 5 is provided with the scale 6 measuring liquid level, described glass tube 5 diameter is less than 0.5cm, described lid 3 is provided with the handle 7 that can number, described handle 7 is tied with line 8, described handle is connected with glass tube 5 by line 8, and described glass tube 5 outside surface is provided with the plano-convex lens 9 for amplifying reading.
Especially, as preferred value, the diameter of glass tube is 0.3cm.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize instructions of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
