Description
Technical field
The utility model is related to volume weight tube, specifically a kind of centrifugation volume weight tube.
Background technology
According to GB/T12806-2011《Laboratory glassware list graticule volumetric flask》, current laboratory is often with volumetric flask
Specification have 1mL, 2mL, 5mL, 10mL, 20mL, 25mL, 50mL, 100mL, 200mL, 250mL, 500mL, 1000mL, 2000mL and
5000mL；With the reduction of volumetric flask capacity, its precision also reduces therewith, such as 1000mL, 100mL, 10mL and 1mL volumetric flask (A
Level) precision be respectively 0.04%, 0.10%, 0.20% and 1.00%.The precision of volumetric flask is improved, feasible method is to subtract
Low capacity bottle bottleneck internal diameter, but volumetric flask bottleneck internal diameter is too small, then liquid wall built-up, bubble and foam are easily produced during constant volume, and
And these phenomenons are all not easy to eliminate, and can cause larger experimental error.Therefore volumetric flask bottleneck internal diameter is minimum generally only at present
It is 7 ± 1mm.
Utility model content
The purpose of this utility model there is provided a kind of centrifugation volume weight tube, solve existing volumetric flask bottleneck internal diameter excessive and not
Suitable for the deficiency of micro liquid precise volume setting, using ultracentrifugal principle, solve liquid wall built-up, bubble, foam and cause
Error problem, improves the precision of volume weight tube.
The utility model now proposes following technical scheme：
One kind centrifugation volume weight tube, including centrifuge tube and sealing device, described centrifuge tube by the mouth of pipe, drainage lumens, neck tube chamber,
Outer wall, cavity volume composition, the mouth of pipe are provided with funnel-form drainage lumens, cylindrical neck tube are connected with below drainage lumens for cylinder lower section
Chamber, neck tube chamber periphery is provided with outer wall, there is containing mark line on outer wall, the lower section connection cavity volume in neck tube chamber, the described mouth of pipe, draws
Chamber, neck tube chamber, outer wall, cavity volume concentrically line are flowed, described sealing device is arranged on the mouth of pipe.
Described neck lumen diameter can be less than the 7 ± 1mm of minimum diameter of volumetric flask bottleneck.
Is there is wall built-up, bubble, the error phenomenon of foam and is solved by high speed centrifugation in described neck tube cavity wall.
Described sealing device is the one kind in the centrifugation pipe close with sealing property, centrifugation lid and centrifugation pipe cap.
Using above technical scheme of the present utility model, the beneficial effect that can be reached has：
Centrifugation volume weight tube of the present utility model utilizes ultracentrifugal principle, solves liquid wall built-up, bubble, foam and causes
Error problem, substantially reduces bottleneck internal diameter, is more suitable for the precise volume setting of micro liquid, improves the precision of volume weight tube.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to accompanying drawing 1, one kind centrifugation volume weight tube, including centrifuge tube 1 and sealing device 2, described centrifuge tube 1 is by the mouth of pipe
11st, drainage lumens 12, neck tube chamber 13, outer wall 16, cavity volume 14 are constituted, and the mouth of pipe 11 is provided with funnel-form drainage lumens for cylinder lower section
12, the lower section of drainage lumens 12 is connected with cylindrical neck tube chamber 13, and the periphery of neck tube chamber 13 is provided with outer wall 16, has capacity to carve on outer wall 16
Degree line 15, the lower section connection cavity volume 14 in neck tube chamber 13, the described mouth of pipe 11, drainage lumens 12, neck tube chamber 13, outer wall 16, volume
The concentrically line of chamber 14, the sealing device 2 is arranged on the mouth of pipe 11.
Micro liquid is entered by the mouth of pipe 11, by the collection of drainage lumens 12, neck tube chamber 13 is imported, finally by neck tube chamber 13
Into cavity volume 14, when liquid level reach containing mark line below 15 and very close to when, stop adding liquid, by the pipe of centrifuge tube 1
Mouthfuls 11 add sealing device 2, are put into centrifuge, after observed after high speed centrifugation neck tube chamber 13 liquid level whether with containing mark line 15
Concordantly, the constant volume of micro liquid is concordantly then completed；If liquid level is also under containing mark line 15, minimal amount of liquid is added with dropper
Body, places into centrifuge, so repeatedly, until liquid level is concordant with containing mark line 15.
Embodiment 1：5mL is centrifuged volume weight tube
Centrifugation volume weight tube volume is 5mL, and centrifuge tube 1 adapts to 10mL centrifuge rotors, and the internal diameter of neck tube chamber 13 is 2mm, close
Seal apparatus 2 are the centrifugation pipe close with sealing property.
Embodiment 2：1mL is centrifuged volume weight tube
Centrifugation volume weight tube volume is 1mL, and centrifuge tube 1 adapts to 2mL centrifuge rotors, and the internal diameter of neck tube chamber 13 is 1mm, sealing
Device 2 is the centrifugation lid with sealing property.
