The utility model discloses a design of needle tubing formula utilizes the piston pressurization to make filtrating discharge smoothly, and the double -stranded chou that saves among the original mounting constructs.

Description

A kind of device measured for content of starch in tobacco and tobacco product

Technical field

The utility model belongs to composition measurement field in tobacco and tobacco product, is specifically related to one and grows tobacco and the ultrasonic extraction device of content of starch in tobacco product.

Background technology

At present, in tobacco, Starch Assay Procedure has acid hydrolyzation, enzymatic isolation method and colourimetry.Front 2 kinds of methods are all the glucose measuring hydrolysis generation, and operation steps is many, and analysis efficiency is low, and acid hydrolyzation can, by the polysaccharide hydrolysis outside starch, cause measurement result higher; Colourimetry is the absorbance of the complex compound using Spectrophotometric Determination of Iodine and starch, although easy and simple to handle, each mensuration all needs manual operations; And continuous flow method is by photometry robotization, the method for having generally acknowledged at present is YC/T216-2013, and the method detection speed is fast, and efficiency is high, is applicable to conventional analysis.But its device needs double-strand ball to give air pressure, by filtrate filtering (going out), cause the inconvenience such as time-consuming, effort.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model adopts needle tube type design, utilizes piston pressurization that filtrate is discharged smoothly, saves the double-strand spherical structure in original device.

The technical scheme that the utility model adopts is: a kind of device measured for content of starch in tobacco and tobacco product, it is characterized in that: comprise glass urceolus, the effect of described glass urceolus tobacco sample and reagent can be put into wherein to carry out the steps such as ultrasonic extraction filtration; Be positioned at the G3 core of glass urceolus, described G3 core aperture is 4.5 ~ 9 μm, filtration; Be positioned at the through type cock of glass urceolus bottom, the circular cone cock body that described through type cock comprises valve rod and rotates with valve rod, described circular cone cock body is provided with clear opening, to realize the effect that when valve rod rotates, control filtrate flow goes out, described through type cock has the advantages such as structure is simple, switch rapid, good airproof performance; The core bar corresponding with glass urceolus internal diameter, described core bar lower end is connected with silica piston, and upper end is hand-pushing handle, it act as and drives piston to move in urceolus, and described silica piston, in glass urceolus, moves downward with the motion of core bar, give filtrate pressure, make it discharge smoothly.

Embodiment

Be further described originally novel below in conjunction with accompanying drawing.

As Figure 1-3, the technical scheme that the utility model adopts is: a kind of device measured for content of starch in tobacco and tobacco product, it is characterized in that: comprise glass urceolus 1, described glass urceolus 1 effect tobacco sample and reagent can be put into wherein to carry out the steps such as ultrasonic extraction filtration; Be positioned at the G3 core 2 of glass urceolus 1, described G3 core 2 aperture is 4.5 ~ 9 μm, filtration; Be positioned at the through type cock 3 of glass urceolus 1 bottom, the circular cone cock body that described through type cock comprises valve rod and rotates with valve rod, described circular cone cock body is provided with clear opening, to realize the effect that when valve rod rotates, control filtrate flow goes out, described through type cock 3 has the advantages such as structure is simple, switch rapid, good airproof performance; The core bar 4 corresponding with glass urceolus 1 internal diameter: described core bar 4 lower end is connected with silica piston 5, and upper end is hand-pushing handle, it act as and drives piston to move in urceolus, described silica piston 5 is in glass urceolus 1, move downward with the motion of core bar 4, give filtrate pressure, make it discharge smoothly.

This novel method of operating is:

1. accurately take 0.25g sample in glass urceolus, add 25mL80% ethanol-saturated nacl aqueous solution, room temperature ultrasonic extraction 30min;

2. take out funnel, open cock, promote core bar, give extract pressure by piston, make it be flowed out by G3 core.Again with sample residue in 2mL80% ethanol-saturated nacl aqueous solution washing funnel, discard cleansing solution, cut-out tap with core bar pressurization;

3. in urceolus, add 15mL40% perchloric acid solution, room temperature ultrasonic extraction 10min, then add 15mL water in funnel, after mixing, open cock, promote core bar, make starch isolation liquid flow in 50mL triangular flask by G3 core, for subsequent use.
