Description

A multi-purpose sample box

technical field

The utility model relates to a commonly used experimental sampling tool for biochemical laboratories, molecular laboratories and hospital laboratories, in particular to a sample loading box mainly used for four-channel, eight-channel and twelve-channel samplers.

Background technique

Chinese patent publication number is CN202049157U on November 23rd, 2011, discloses a kind of multi-purpose sampling tank. The interior of the sampling tank is designed as a conjoined V-shaped groove, the grooves are twelve, and the interval is the interval between four and eight sample injector tips. The sample tank with this structure is only convenient for taking large and medium doses of liquid. For many biochemical or molecular tests, the amount of reagents is very small and the price is expensive. When there is only a small amount of liquid reagent in the V-shaped groove, the liquid reagent will appear broken flow and uneven distribution at the bottom of the V-shaped groove. The amount of liquid reagent absorbed by the gun tip is not the same, which will cause the error of the experiment. Even part of the liquid reagent cannot be sucked and poured out, causing unnecessary waste.

Contents of the invention

The technical problem to be solved by the utility model is to provide a multi-purpose sample adding box which can be absorbed evenly by the sample injector even in a small dose, thereby saving reagents and reducing test errors.

The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a multi-purpose sample loading box, including a frame and a first V-shaped groove, the first V-shaped groove is arranged in the frame, and it is characterized in that the first The bottom of the V-shaped groove is provided with a plurality of concave holes, and the distance between the bottoms of adjacent concave holes is the distance between adjacent tips of the multi-channel sampler. The diameter of the concave holes is 2 mm to 11 mm. The depth of the concave hole is 2mm-7mm.

A confluence channel is provided at the bottom of the first V-shaped groove, the bottom of the confluence channel is arc-shaped, and the concave hole is arranged at the bottom of the confluence channel.

It also includes a frame, the frame includes four sides, the opening of the first V-shaped groove faces upwards, and the reverse side of the frame forms two second V-shaped grooves, the opening of the second V-shaped groove faces downwards, and the opening of the first V-shaped groove faces downwards. The V-shaped groove is located between the two second V-shaped grooves.

The frame is a trapezoidal platform, the width of the lower side of the frame is L1, the width of the upper side of the frame is L2, and L1=2L2.

The second V-shaped groove is provided with a partition, which is divided into two sample slots, one is the sample slot for the tip of the eight-channel sampler, and the other is the sample slot for the tip of the four-channel sampler. .

The upper edges between the adjacent concave holes are directly connected. Avoid leaving excess liquid reagents at the lands of adjacent wells.

Conducting holes are provided on the partition walls between the adjacent recessed holes, and the diameter of the conducting holes is 0.8mm-1.2mm.

The setting of the conduction hole enables the reagents between the concave holes to flow, further ensuring the uniformity of sampling by the pipette tip of the sample injector.

The diameter of the concave hole is 9 mm, the depth of the concave hole is 3.5 mm, and the diameter of the through hole is 1 mm. According to a large number of experiments, the uniformity of sampling is the best when the above size is adopted. the

A waterproof membrane is arranged in the first V-shaped groove and the second V-shaped groove. When a drop of liquid reagent is in the shape of a ball on the waterproof membrane, when a small amount of liquid reagent is in the V-shaped groove, the liquid is intermittent and will not be connected into one piece. At this time, it is difficult for the nozzles of the sampler to absorb evenly.

Compared with the prior art, the utility model has the advantage that when the V-shaped groove only has a micro-dosage of liquid, it can prevent the reagent from being dispersed everywhere at the bottom of the V-shaped groove, and the liquid reagent will be concentrated in each concave hole. The gun head of the sample injector corresponds to the concave hole, thereby saving reagents and reducing experimental errors.

The confluence channel facilitates the concentration of liquid reagents into each concave hole.

There is a first V-shaped groove on the front side of the frame, and two second V-shaped grooves are formed on the reverse side of the frame, increasing the usage of the sample box.
