  和蕴丰国际贸易（上海）有限公司 产品名称:YCP-200二氧化碳培养箱 采用国际先进的超声传感器和数码显示、宽温度带控制等多项技术，具有操作简便、可靠性高、稳定性好、使用寿命长等优点，广泛应用于YL、食品、生物工程和科研教学等领域。 技术性能及参数 工作温度范围：室温+3℃-60℃ 恒温控制精度：±0.2℃ CO2浓度控制范围：0%-20% CO2浓度控制精度：5%时±0.2% 工作室有效容积：200L CO2浓度正常上升至预置值小于10分钟(5%时) 产品名称:二氧化碳培养箱 CO2培养箱主要由箱体结构件、温度控制系统和CO2浓度控制系统三部分组成。 1、箱体结构件由外壳、保温材料和不锈钢水套组成。工作室的设计是关键。采用水套方式，即除正面玻璃门外，其余五面均为充满水的不锈钢夹层，通过热水的循环，使工作室处于等温水的夹层包围中，因此受热均匀、恒定，升温快，降温慢，即使停电5～6小时，也保证细胞存活。采用双层门设计，内面的玻璃门便 于观察细胞生长，又对环境干扰较小；外门内侧设有自动控温的衬板，使玻璃门不结露、不受环境温度变化的影响。工作室内的风扇使气体循环，使工作室的温度和CO2 浓度均匀。水套顶层采用台阶状设计（该设计获得国家ZL），既保证了培养箱顶部的水层均匀，又避免了风扇电机的高温和环境变化对工作室温度均匀性的影响。制造工艺也能保证体形变减少。 2、温度控制系统采用三路检测、三级控制的电路，而且还有防止温度过部电路。（而有些进口培养箱是单路检测、二级控制电路）温度传感器是先进的电压型集成电路温度传感器，而不是常用的热敏电阴、半导体、热电偶等传感器。 3、CO2浓度控制采用超声波传感器，具有性能稳定、检测速度快、能适应潮湿的箱内环境、寿命长不易损坏、线性好等优点（此技术已获得国家ZL）。而国内外同类产品多数采用热导式和红外线式。热导式传感器结构热导式传感器结构简单、成本低廉，但过于灵敏，受环境影响大，容易产生零点漂移。红外线式传感器不能在潮湿的培养箱内工作，便采用外置传感器方式，将培养箱内的气体用气泵抽出并冷凝去湿后再检测，然后将气返送回箱内。这种方式管路复杂，机械耗损大，检测结果滞后，故障率也高。 自动控制CO2浓度 只要给定一个设定值，仪器便自动控制CO2浓度，比较流量计方式，操作更简单，省气精度高，稳定性好。 ◆采用ZL技术水套结构 采用ZL技术水套结构使培养室Z大限度的被水的夹层包容，增大水套容量，帮有极高的可靠性和稳定性；无缝焊技术，使细菌难以生长。 ◆精密控制温度 采用三路集成温度传感器，精密控制水温、门温、室温，使培养箱温度极少受环境温度变化的影响；超温双层保护，有极高的安全性。 ◆采用ZL技术超声波方式测定CO2浓度 采用超声波传感器，无机械磨损，使用寿命长，稳定性好，高湿度不受影响。 ◆一机二用 温度和CO2浓度分别控制，关闭CO2控制系统，可单独做高精度培养箱使用。 ◆操作方便，显示直观 数字显示温度、CO2浓度，门加温、水加温、水位变化都有LED显示。 ◆双玻璃门 200升的大型箱采用上下两扇双玻璃门设计，可以极大的减少开门对培养室的影响，便于快速恢复培养环境。 ◆小型化 50升小型箱可作桌面培养箱使用；因为体积小，温度和CO2浓度恢复快，特别省气。 CARBON BIOXIDE INCUBATOR Carbon dioxide incubator is composed by box configuration ， temperature control system and CO2 thickness control system. ◆ Box configuration is composed by crust ， heat preservation material ， stainless steel water jacket . The design of the workroom is linchpin . It is adopted the water jacket technology ， namely ， except the front glass door ， other 5 surfaces are all stainless steel interlayer full with water . With hot water circulation ， water interlayer in same temperature surrounds the workroom . Heated equably ， temperature invariableness ， the fast rising temperature and the slow falling temperature are the advantages of this workroom . Though power cut for 5-6 hours ， it can also make the cell alive . Adopt the design of double door ， the glass door inside is convenient for observation of dew and other influence . The air in the workroom can be circulated by fans for uniformity of the temperature and CO2 thickness in workroom . The top of the water jacket is step shape (declared the nationality patent) ， for uniformity of the mater tier in incubator and prevention of high temperature in workroom . The manufacturing technical can also guarantee the shape of the incubator . ◆The circuit of 3-route check ， 3-step control and high temperature prevention is adopted in temperature control system . (some import incubator circuits are single route check ，2 step control) Temperature sensor is unusually adopted the voltage concentration circuit . ◆CO2 thickness control is adopted the ultrasonic sensor with stable capability ， fast checking speed for adaptation of the wet environment ， long service life and good linearity . (Declared the nationality patent) . But the same kind of this products in the world are adopted the heat conduction and infrared . The sensor configuration of the heat conduction is simpleness and low expedition ， but it is sensitive by environment influence and easy to zero drift . The infrared sensor can’t work in wet incubator ， so it is adopted with the outlay sensor by pump the air inside and check after freezing ， and then it will send the air back to the incubator . This system has disadvantages of complex duct ， high mechanical waste ， hysteresis checking result and high fault rate . Auto-control of CO2 thickness and comparison of flow are worked when a value is set ， so it has the advantages of easily operation ， high gas save ， high precision and good stabilization . ◆The configuration of water jacket with the patent technology makes the incubator surrounded by water interlayer for high capacity of the water jacket . ◆Adopt the sensor of 3-route integrated circuit for precise control of water temperature ， door temperature ， room temperature and prevention influence of environment temperature . Over temperature with the protection of double layers for safety . ◆Adopt the ultrasonic sensor ， low mechanical waste ， long service life ， good stabilization ， no influence by high humidity . ◆Temperature and CO2 thickness can be controlled separately . Work alone with high precise . ◆The digital display of temperature and CO2 thickness ， the LED display of door rising temperature ， water rising temperature and water level variety . ◆The large incubator(200L) is adopted with double glass doors for prevention influence of door opening and fast recover of the environment . ◆The small incubator (50L) can be used as table-type for fast recover of the temperature and CO2 thickness .
