[0002] Mandelic acid is a compound that occurs naturally in some foods, especially in almonds, apricot kernels, cherries, apple seeds, and other stone fruits. It belongs to the class of hydroxy acids, which often have a bitter taste. In almonds, mandelic acid is a toxin, but it is not usually a problem when consumed in moderation. However, excessive intake of mandelic acid may cause symptoms of poisoning, such as dizziness, nausea, vomiting, and diarrhea. Therefore, when consuming foods containing mandelic acid, you should be careful to consume it in moderation to avoid adverse reactions.

[0033] Preferably, the width of the first slide groove 101a and the second slide groove 102a is slightly larger than the limiting rod 105, so that there is more adjustment space when adjusting the first clamping plate 101 and the second clamping plate 102, and it is suitable for test tubes of more shapes and sizes.

[0034] A limit rod 105 is disposed between the first slide groove 101 a and the second slide groove 102 a . A first spring 106 is disposed on an outer wall of the limit rod 105 . The first spring 106 is located between the first connecting plate 103 and the second connecting plate 104 .

[0035] Preferably, the first spring 106 is used for resetting the first clamping plate 101 and the second clamping plate 102 , so that the first clamping plate 101 slides along the direction of the limiting rod 105 toward one side of the second clamping plate 102 after the laboratory preparation is completed.

Pressing the operating block 205 again can make the top block 208b disengage from the positioning hole 202a. After moving the sliding block 204 to different heights, pressing the operating block 205 again can complete the fixing of the sliding block 204.
