Description

A kind of homogenate pipe driver

Technical field

The utility model relates to a kind of homogenate pipe driver, belong to biological organization material is carried out fragmentation and homogenate equipment technical field, be widely used in fields such as biological medicine, environmental science, agriculture forest and husbandry, food hygiene, chemical, be particularly suitable for biology laboratory and use.

Background technology

The fragmentation of biological organization material and homogenate, be in specific solution, material to be carried out fragmentation, grinding by physical method, and make it to be dispersed into the method for fine particle shape suspending liquid, be one of important step of carrying out nucleic acid, protein and other trace element extractions, separate and detecting, be widely used in fields such as biological medicine, environmental science, agriculture forest and husbandry, food hygiene, the animal and plant quarantine, chemical.

Existing homogenate method has: homogenate pipe hand-ground, electronic homogenate, ultrasonication and mortar grinding etc., each method has the technological means that adapts, or device, equipment, but all has certain shortcoming.

1, homogenate pipe hand-ground: the homogenate pipe is generally glass material, is made up of through the tube core of frosted processing outer tube and outer wall that inwall is handled through frosted, constitutes movingly tight with minimum gap between outer tube and the tube core.During operation, one holds outer tube, and another is held tube core and does to grind relatively motion, utilizes the two cylindrical surface shearing force of inside and outside frosted that a small amount of or micro-biological sample is carried out fragmentation and homogenate.This method that is to say sheerly in manual operation, makes outer tube and tube core do that relative to grind what move be that people's two hands are finished.Because homogenate pipe low price, easy and simple to handle, the homogenate pipe of glass material also can adopt methods such as strong acid immersion, high-temperature baking, high pressure steam to carry out decontamination, sterilization, sterilization, and biology laboratory at present adopts this method to carry out the tissue homogenate operation.But this manual methods is not by any driven tool or equipment, and its application is restricted, and reason is: at first be because of manual operations, waste time and energy that labour intensity is bigger, particularly labour intensity is bigger for a long time for sample size, and inefficiency; In addition, the homogenate pipe of glass material is handled to increase shearing force through frosted, and manual operation was not fragile at that time to be split, and causes the final material of fragmentation and homogenate to scrap or quality can not get guaranteeing, also can cause security incidents such as staff is injured simultaneously.

2, electronic homogenate: be to realize grinding motion with electric homogenizer.Existing electric homogenizer has multiple different form and specification, but ultimate principle all is to adopt the blade of high speed rotating that sample is smashed.Its advantage is: electric homogenizer is easy and simple to handle, and what have can also handle a plurality of samples, high efficiency, safety simultaneously.But its shortcoming is also very outstanding: for addressing this problem, prior art is to adopt metal material to make special container and cutter head.At first be,, and adopt not easy cleaning of canister and cutter head, can not adopt the method decontamination of bubble acid, can not under the strong acid and strong base condition, use corrosion easily because of the homogenate pipe of glass material is not suitable for the blade apparatus of this kind high speed rotating; Next is, costs an arm and a leg, and all wearing details all need supporting, and versatility is poor.

3, ultrasonication: be to adopt the ultrasonic resonator principle that the sample of trace is carried out fragmentation with Ultrasonic Cell Disruptor.Because the restriction of principle and price is high, the Ultrasonic Cell Disruptor usable range is comparatively limited to.

4, mortar grinds: mortar grinds principle and approaches homogenate pipe hand-ground, and its homogenate pipe adopts ceramic material more, and advantage is: because of adding tissue abrasion under the liquid nitrogen cryogenics condition, can effectively suppress the degraded of RNA, so be applied to the extraction of RNA more.Its shortcoming and homogenate pipe hand-ground are basic identical.

Summary of the invention

The purpose of this utility model is, homogenate pipe hand-ground wastes time and energy in the prior art in order to overcome, inefficiency and misoperation be cracked problem easily, overcoming simultaneously electronic homogenate in the existing technology again can only adopt canister can not adopt glass homogenate pipe because of the structure of the blade of high speed rotating, thereby can not realize that strong acid soaks, high-temperature baking, methods such as high pressure steam are carried out decontamination, sterilization, the shortcoming of sterilization, a kind of advantage that had both had homogenate pipe hand-ground is provided, has electronic homogenate advantage in the prior art again, the homogenate pipe that is fit to all size, the non-rotary a kind of dynamic driver of homogenate pipes of interior tube core by the rotation of frictional force drives homogenate pipe outer tube.

The technical scheme of a kind of homogenate pipe of the utility model driver is: it comprises that housing, motor and one are used to drive the friction piece of the outer tube of homogenate pipe around the tube core rotation of homogenate pipe; Described friction piece and reduction gear are that the power output shaft of mechanical reduction gear or belt reduction unit is connected; Friction piece is an integrated member, and upper center is to be used for driving the up big and down small infundibulate pit of the outer tube of homogenate pipe around the tube core rotation of homogenate pipe with friction force.

Further technical scheme with additional technical feature is:

Described homogenate pipe driver, its friction piece is positioned at the outside of housing, and its material is a rubber.

Described good homogenate pipe driver is fixed the bracing frame of dead in line of the power output shaft of a tube core axis that is used to make the homogenate pipe and reduction gear on the housing.

Described homogenate pipe driver, its bracing frame have two columns and horizontal Beam or loam cake at least.

Described homogenate pipe driver, its horizontal Beam or on be stamped the center pit that is located by connecting with tube core upper end, a connecting hole that is connected with column in addition.

The utility model has following some beneficial effect: 1. this driver can provide machine power for the tissue homogenate operation of homogenate pipe, reduces user's labour intensity, increases work efficiency; 2. friction piece adopts high coefficient of friction material to make, and is designed to infundibulate with the surface of contact of homogenate pipe, can cooperate the homogenate pipe of different specification size and sufficient power is provided; 3. this driver utilizes mechanical force to drive the homogenate pipe, can obtain high rotational speed, reaches satisfied homogenate effect fast.Therefore, before the homogenate with homogenate pipe, lysate in precooling on ice, temperature can remain near zero degree in the relatively short time of homogenate finishing, and obtains the low-temperature homogenate effect, the degraded of RNA in the tissue in the time of effectively suppressing homogenate; 4. adopt this driver homogenate effect stability, the error of bringing because of operator's individual factor in the time of reducing homogenate pipe hand-manipulated improves repeatable; 5. the physical shock action when adopting this driver to eliminate manual operation between homogenate pipe outer tube and the tube core, the homogenate pipe is difficult for chipping in operation.In addition, this driver is separate with the homogenate pipe, and the homogenate pipe that does not influence glass material carries out operations such as pickling, high-temperature baking and high pressure steam sterilization, helps preventing that sample from polluting in the homogenate process; 6. accurate positioning when bracing frame being arranged, rotary resistance is little, further alleviates people's labour intensity.
