低溫試驗箱結構特點:
該儀器選用上翻蓋，內置推拉玻璃，加厚保溫層,對低溫保持效果好，實驗方便，恒溫槽采用防腐性較強的合金板，外用優質鋼板制作，中間充聚胺脂保溫材料。
Structural characteristics of low temperature test chamber:
The instrument uses a flip cover, built-in push-pull glass, thickened thermal insulation layer, which has a good effect on low temperature retention and convenient experiments. The thermostatic bath is made of high-quality steel plate with external corrosion resistance, and is made of polyurethane thermal insulation material in the middle.

低溫試驗箱冷凍須知：
★放置試樣時，試樣與試樣、試樣與冷凍箱內膽要留一定的間隙，以保證冷氣流動，降溫均勻。
★在試驗濕度較高物件和易失水份的物件，請用密封膠好的食品袋或保鮮紙包好放入，以防水份跑出，在工作室內結霜，影響制冷。
★嚴禁在冷凍箱內存放易揮發、燃燒的氣體、液體，如強堿、強酸、汽油、酒精等物品。
★一次放入的試樣不能多，否則會使壓縮機長時間不停機而且箱內溫度下降緩慢，反而達不到要求。
★工作完畢后，切斷電源，取出已冷凍樣品，打開冷凍箱門讓其自然升溫，化霜層融化，將水放出用軟布吸干擦凈
Instructions for freezing in low temperature test chamber:
★ When placing the sample, leave a certain gap between the sample and the sample, and the freezer container to ensure that the cold air flows and the temperature is uniformly reduced.
★ In the test with high humidity and volatile materials, please put them in a food bag or plastic wrap with good sealant, run out with waterproofing, frost in the working room, and affect refrigeration.
★ It is strictly prohibited to store volatile and flammable gases and liquids in the freezer, such as strong alkali, strong acid, gasoline, alcohol and other items.
★ Do not put more samples at one time, otherwise the compressor will not stop for a long time and the temperature in the box will drop slowly, but it will not meet the requirements.
★ After the work is completed, cut off the power supply, take out the frozen samples, open the freezer door to allow it to warm up naturally, the defrost layer will melt, and drain the water with a soft cloth and wipe clean
