一般培養基用1．05kg /cm2，121．3℃15—30分鐘可達到*滅菌的目的。滅菌的溫度及維持的時間隨滅菌物品的性質和容量等具體情況而有所改變。例如含糖培養基用0．56kg/cm2（8磅/英寸2），112．6℃滅菌15分鐘，但為了保證效果，可將其他成分先行121．3℃，20分鐘滅菌，然后以無菌操作手續加入滅菌的糖溶液。又如盛于試管內的培養基以1．05kg/cm2，121．3℃滅菌20分鐘即可，而盛于大瓶內的培養基以1．05kg/cm2滅菌30分鐘。
蒸汽壓力所用單位為kg/cm2（千克/厘米2），它與lb/in2（磅/英寸2）和溫度的換算關系見表Ⅵ-5。
 實驗室中常用的高壓蒸汽滅菌鍋有立式、臥式和手提式等幾種，其構造如圖Ⅵ-4。本實驗介紹手提式高壓蒸汽滅菌鍋的使用方法。
實驗試劑
牛肉蛋白胨培養基
實驗設備
手提式高壓蒸汽菌鍋等
實驗材料
培養皿（6套一包）
實驗原理
蛙或蟾蜍等兩棲類動物的一些基本生命活動和生理功能與溫血動物相似，而其離體組織生活條件易于掌握，在任氏液的浸潤下，神經肌肉標本可較長時間保持生理活性，因此，在生理學實驗中常用蛙或蟾蜍坐骨神經腓腸肌離體標本來觀察神經肌肉的興奮性、興奮過程以及骨骼肌收縮特點等。

General medium with 1.05kg / cm2, 121.3 ° C for 15-30 minutes to achieve the goal of complete sterilization. The sterilization temperature and the duration of the sterilization will vary depending on the specifics such as the nature and capacity of the sterilized items. For example, the sugar-containing medium is sterilized at 0.56 kg / cm2 (8 psig) for 15 minutes at 112.6C. However, in order to ensure the effect, other components may be sterilized at 121.3C for 20 minutes, Aseptically add sterilized sugar solution. For another example, the culture medium contained in the test tube is sterilized at 1.05 kg / cm2 and 121.3C for 20 minutes. The medium in the large bottle is preferably sterilized at 1.05 kg / cm2 for 30 minutes.
The unit for steam pressure is kg / cm2 (kg / cm2) and is shown in Table VI-5 as a function of lb / in2 and temperature.
 High-pressure steam sterilizer commonly used in laboratories are vertical, horizontal and hand-held several, the structure shown in Figure VI-4. This experiment introduces the use of portable autoclaves.
Experimental reagents
Beef peptone medium
Laboratory equipment
Portable high-pressure steam bacteria pot and so on
Experimental Materials
Petri dish (6 sets of a pack)
Experimental principle
Some basic life and physiological functions of amphibians, such as frogs and toads, are similar to those of warm-blooded animals, and the living conditions of their isolated tissues are easy to grasp. Neurovascular specimens can retain their physiological activity for a longer period of time under the influence of Ringer's solution In physiology experiments commonly used frog or toad sciatic nerve gastrocnemius specimens to observe the excitability of neuromuscular, excitement and skeletal muscle contraction characteristics.
