The handle for being fixedly arranged on the sieve of circumferential wall bottom and being fixedly arranged on circumferential wall；The internal diameter of circumferential wall is from circumferential wall
Upper end is gradually reduced to lower end；Two hand baskets are arranged with upper and lower stacked system；The bottom for the hand basket being located above is under being located at
In the circumferential wall of the hand basket of side；The sieve of the sieve for the hand basket being located above and underlying hand basket does not contact, and is located at upper
The space for accommodating sample is formed between the sieve of hand basket and the sieve of underlying hand basket of side；Underlying hand basket
Bottom be connected to the inner wall of tube body.
The outer diameter of underlying hand basket bottom is less than the internal diameter at the top of tube body and is greater than the internal diameter of bottom.
The bottom for the hand basket being located above is connected to the inner wall of the circumferential wall of underlying hand basket.
Handle and circumferential wall are integrally formed.
The material of handle and circumferential wall is transparent plastic.
The top of tube body is equipped with lid.
The material of tube body is transparent material.
The positive effect of the utility model is: the freezing substitution sample funnel of the utility model can use existing
The common equipment in laboratory --- liquid transfer gun head is made (pipette tips can make two hand baskets), have production it is simple,
The advantages of easy to make, manufacturing speed is fast, low manufacture cost.The freezing substitution sample funnel of the utility model has structure letter
It is single, easy to operate.The freezing substitution sample funnel of the utility model can make biological sample both can be in cold liquid environment
Dehydration is completed, and not easy to lose, has the advantages that extraction sample is convenient and not easy to lose.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model preferred embodiment.
Fig. 2 is the structural schematic diagram of the underlying hand basket of the utility model preferred embodiment.
Specific embodiment
A preferred embodiment is named, and completely illustrates the utility model in conjunction with attached drawing to become apparent from.
As shown in Figure 1, a kind of freezing substitution sample funnel comprising tube body 10, the top of tube body 10 are open end, tube body
10 bottom is closed end.The internal diameter of tube body 10 is gradually reduced from the top of tube body to bottom.
Hand basket there are two being set in tube body 10.Two hand baskets are arranged with upper and lower stacked system, the hand basket being specially located above
30 and underlying hand basket 20.
For two hand baskets in addition to size is different, structure is all the same.
As shown in Fig. 2, underlying hand basket 20 include circumferential wall 21, be fixedly arranged on the sieve 22 of circumferential wall bottom with
And it is fixedly arranged on the handle 23 on circumferential wall.The internal diameter of circumferential wall 21 is gradually reduced from the upper end of circumferential wall to lower end.Hand
Handle 23 and circumferential wall 21 are integrally formed.The material of handle 23 and circumferential wall 21 is plastics.
The structure for the hand basket 30 being located above is identical with the structure of underlying hand basket 20, and details are not described herein again.
The bottom for the hand basket 30 being located above is set in the circumferential wall of underlying hand basket 20.The hand basket being located above
The sieve of 30 sieve and underlying hand basket 20 does not contact；The sieve for the hand basket being located above and underlying hand basket
The space for accommodating sample is formed between sieve.
The bottom of underlying hand basket 20 is connected to the inner wall of tube body 10.The outer diameter of underlying 20 bottom of hand basket is small
Internal diameter at the top of tube body 10 and the internal diameter greater than 10 bottom of tube body.
The bottom for the hand basket 30 being located above is connected to the inner wall of the circumferential wall of underlying hand basket 20.
The top of tube body 10 is equipped with lid 40.The material of tube body 10 is transparent material.
The freezing substitution sample funnel of the utility model can be carried out using the common equipment liquid transfer gun head in existing laboratory
Production.Manufacturing process step specifically: 1, liquid transfer gun head is cut, produce the circumferential wall and handle of hand basket；2, exist
The bottom bonded metal sieve of circumferential wall；3, step 1 and step 2 are repeated, another hand basket is made；And one of hand basket
Size be greater than another hand basket；4, the hand basket that the small hand basket insertion size of size is big, forms the hand basket being located above and position
Hand basket in lower section；5, two hand baskets are put into small test tube.Through the above steps, the freezing substitution of cost of manufacture utility model
Sample funnel.One liquid transfer gun head can make two hand baskets.
Simple, easy to make, manufacturing speed is fast, cost of manufacture with making for the freezing substitution sample funnel of the utility model
