一般培养基用1．05kg /cm2，121．3℃15—30分钟可达到*灭菌的目的。灭菌的温度及维持的时间随灭菌物品的性质和容量等具体情况而有所改变。例如含糖培养基用0．56kg/cm2（8磅/英寸2），112．6℃灭菌15分钟，但为了保证效果，可将其他成分先行121．3℃，20分钟灭菌，然后以无菌操作手续加入灭菌的糖溶液。又如盛于试管内的培养基以1．05kg/cm2，121．3℃灭菌20分钟即可，而盛于大瓶内的培养基以1．05kg/cm2灭菌30分钟。
蒸汽压力所用单位为kg/cm2（千克/厘米2），它与lb/in2（磅/英寸2）和温度的换算关系见表Ⅵ-5。
 实验室中常用的高压蒸汽灭菌锅有立式、卧式和手提式等几种，其构造如图Ⅵ-4。本实验介绍手提式高压蒸汽灭菌锅的使用方法。
实验试剂
牛肉蛋白胨培养基

实验材料
培养皿（6套一包）
实验原理
蛙或蟾蜍等两栖类动物的一些基本生命活动和生理功能与温血动物相似，而其离体组织生活条件易于掌握，在任氏液的浸润下，神经肌肉标本可较长时间保持生理活性，因此，在生理学实验中常用蛙或蟾蜍坐骨神经腓肠肌离体标本来观察神经肌肉的兴奋性、兴奋过程以及骨骼肌收缩特点等。

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.
