Description

Technical Field

[0001] This utility model relates to the field of biological experimental equipment technology, specifically to a plant tuber sampler with a hole punch. Background Technology

[0002] In biological research, particularly in studies related to fruit and vegetable preservation, tuber sampling plays a crucial role. Traditionally, when conducting transgenic plant testing and measuring various physiological and biochemical indicators, tuber samples are typically taken using a knife. The sample is placed on a cutting board and manually cut with the knife. However, because the cutting board and knife cannot be guaranteed to be completely sterile, interference from external contamination is difficult to avoid during sampling. Furthermore, it is challenging to maintain consistency in sample size and weight. Additionally, disposable gloves must be worn during the process, and even slight carelessness can result in cuts, causing significant inconvenience. The entire sampling process is both time-consuming and labor-intensive, negatively impacting not only the quality and speed of sample collection but also the efficiency and accuracy of experimental results.

[0003] To address the shortcomings of manual sampling, most current patents concern perforated samplers for collecting samples from plant leaves, and some are for fruit and vegetable sampling devices. For example, patent publication CN 117030335 A discloses a batch sampling device for pesticide residue detection in fruits and vegetables. This device includes a sample positioning component, a rotary gradient sampling blade, a sample collection component, a main support, and an electric drive component. Through the cooperation of these components, and by using a cutting blade with decreasing blade length on the rotary gradient sampling blade, it achieves automatic batch and gradient sampling of fruits and vegetables. A sample positioning flange on the sample positioning component enables symmetrical sampling, improving sample representativeness and solving problems such as high labor intensity, low efficiency, sample placement, arbitrary sampling, and poor sample quality in current batch sampling methods. However, these devices have the following drawbacks: complex structure, heavy overall weight, inconvenient sampling operation, and difficulty in cleaning and disinfecting after sampling; sample contamination cannot be avoided during the sampling process, making them unsuitable for tuber sample sampling research in biological laboratories.

The device has a simple structure, is lightweight, convenient for sampling operation, and easy to clean, significantly improving the efficiency of sampling work.
