Description
Technical field
The invention belongs to clearer production technology fields, and in particular to and one kind is suitable for non-metering small-bore glassware,
The cleaning method of especially non-metering capillary glass catheter interior grease.
Background technique
Glassware is common a kind of vessel in laboratory, however in the use process of glassware, inner wall of utensil
According to the difference of its material contained, inner wall can be stained with different types of grease.It can be with for the biggish glassware of bore
Its inner wall is cleaned using test tube brush and other organic solvents, and glassware lesser for bore, such as chromatographic grade
Sample injection bottle, capillary glass conduit, small-bore test tube etc., the especially obstinate grease of the grease adhered on inner wall is can not to carry out clearly
It washes.Currently, being directed to such small-bore glassware, can only just be discarded after a single use, to cause resource
Waste, be unfavorable for clean manufacturing.
Summary of the invention
The present invention is to provide one kind in order to solve the deficiencies in the prior art and be suitable for not measuring small-bore glassware, especially
It is the cleaning method of non-metering capillary glass catheter interior grease.
The present invention is achieved by the following technical solution:
A kind of cleaning method not measuring small-bore glassware internal grease comprising the steps of:
(1) primary heating: glassware to be cleaned is placed in Muffle furnace, heats 20- under conditions of 290-310 DEG C
30min,
(2) reheating: the heating temperature in control Muffle furnace continues to heat at least 3h under the conditions of 480-520 DEG C,
(3) cooling: taking-up glassware, cooled to room temperature,
(4) clear water rinses: the ash content inside glassware is rinsed out with clear water,
(5) dry: the glassware that the glassware after flushing is cleaned up to obtain the final product after dry.
The glassware is the glassware that bore is less than 1cm.
Preferably, the heating temperature in step (1) is 300 DEG C, and the heating temperature in step (2) is 500 DEG C.
Compared with prior art, the present invention is using the method being heated at high temperature, so that the grease on glassivation inner wall of utensil
It is first carbonized and is ashed again, then rinse out remaining ash content with clear water, easy to operate, cleaning efficiency height and the glass after over cleaning
Vessel interior surface without grease residual.Method of the invention can be adapted for various non-metering small-bore glassware inner surface oil
The cleaning of rouge, use scope are wide.By means of the invention it is also possible to clean glassware especially capillary glass conduit well
Internal grease, recycles glassware, reduces the waste of resource, thus reduce production/test at
This, is conducive to clean manufacturing.
Detailed description of the invention
Fig. 1 is the state diagram before the cleaning of small-bore glassware,
Fig. 2 is the state diagram after the carbonization of small-bore glassware,
Fig. 3 is the state diagram after the completion of small-bore glassware cleans by means of the present invention.
Specific embodiment
Below with reference to embodiment and attached drawing, the present invention will be further described, but protection scope of the present invention is not by embodiment
It is limited.
Embodiment 1
A kind of cleaning method not measuring small-bore glassware internal grease comprising the steps of:
(1) primary heating: glassware (as shown in Figure 1) to be cleaned is placed in Muffle furnace, is heated under conditions of 290 DEG C
20min, this process are carbonisation, glassware after carbonization as shown in Fig. 2,
(2) reheating: the heating temperature in control Muffle furnace continues to heat 3h under the conditions of 480 DEG C, this process is to be ashed
Journey,
(3) cooling: taking-up glassware, cooled to room temperature,
(4) clear water rinses: the ash content inside glassware is rinsed out with clear water,
(5) dry: the glassware that the glassware after flushing is cleaned up to obtain the final product after dry.
The glassware is the capillary glass conduit that bore is 1mm, glassware such as Fig. 3 institute after the completion of drying
Show.
The method of the present embodiment is applied into Mr. Yu laboratory, is carried out for the capillary glass conduit for containing walnut oil clear
It washes, cleaning process time-consuming 4h, grease measurement is carried out to the capillary glass vessel after cleaning, result is without grease residual.
The measuring method of fat residue is as follows:
1, beaker is once weighed: being prepared the beaker of a clean dried, is weighed using the electronic balance by metering (accurate
To 0.0001g), record quality is m1;
2, residual grease is extracted: using 10ml petroleum ether (30 DEG C -60 DEG C of boiling range) to the inner wall of the capillary glass conduit after cleaning
It is rinsed, the petroleum ether after flushing is collected in weighed beaker, and being placed in heating on electric hot plate volatilizes petroleum ether；
3, beaker secondary weighing: being put into drier after it is cooled to room temperature for beaker and weighed and (be accurate to 0.0001g), remembers
Record quality is m2；
4, it calculates: oil residue: M=m2- m1=0.0002g, as M < 0.0050g, it is believed that basic without grease residual, it can
See in the capillary glass conduit through over cleaning without fat residue.
Embodiment 2
A kind of cleaning method not measuring small-bore glassware internal grease comprising the steps of:
(1) primary heating: glassware to be cleaned is placed in Muffle furnace, heats 30min under conditions of 310 DEG C,
(2) reheating: the heating temperature in control Muffle furnace continues to heat 3h under the conditions of 520 DEG C,
(3) cooling: taking-up glassware, cooled to room temperature,
(4) clear water rinses: the ash content inside glassware is rinsed out with clear water,
(5) dry: the glassware that the glassware after flushing is cleaned up to obtain the final product after dry.
The method of the present embodiment is applied into Mr. Yu laboratory, the grass tube for containing rapeseed oil is cleaned.Cleaning
Process time-consuming is 4h, is shown to the measurement of Muffle furnace, and the energy consumption in whole process is that (Muffle furnace is under nominal power for 12 degree of electricity
