英国BURKARD PDE0012型POTTER喷雾塔生测喷雾塔采用国际标准的化学喷雾方法,用于有机生物接触实验的教学及科研工作。


英国BURKARD公司作为精密实验室POTTER喷雾塔的主要供应商,可以提供英国BURKARD PDE0012型POTTER喷雾塔生测喷雾塔,仪器设计用于 9cm 范围的循环喷雾。


英国BURKARD PDE0012型POTTER喷雾塔生测喷雾塔是一实验室喷雾设备,其设计功能为向一9cm直径范围内均匀喷雾。适合于化学物品的生测试验研究,可直接喷在生物体或形成残留膜(或残余膜),该设计融合了Rothmsted试验站,Harpenden, Herts, England等的研究成果,包括:喷雾器的快速拆装,气动喷雾台及所有的空气控制安装在控制面板上。喷雾塔安装有一个4英寸0-30lb/立方英寸的压力表。


在使用Potter喷雾塔时操作者通常会有一些危害,尤其在大量样品测试时。这时应该将喷雾塔放置于通风厨中。为了克服残留物质对皮肤的伤害,Burkard公司研究出 自动型Potter喷雾塔,装配有气动Petri培养皿送喂装置。Petri培养皿放置于喷雾台上的喷雾管喷雾范围区域内。通过脚踏开关或气栓开关样品被吸入到预先设定的喷雾点。在给喷嘴实施气压之前完成气动执行器的后续操作。喷雾完成,降低喷雾台向前移动保证顺利移出待测样品。


Burkard公司的Potter喷雾塔全部采用防腐蚀不锈钢制造,不仅更坚固,而且其构造使清理维护非常简单,表面不需要化学阳极?;?。压力计和作业控制系统安装在底部,在平台中心安装有水平仪,可以通过调节底部的四个支脚确保仪器处于严格的水平状态。

喷雾台在气动杆活塞内的高度可以调节,并有四个可锁定偏心定位盘定位不同直径的Petri 培养皿和其他容器,调节喷雾台水平,并调节气动杆和制动器支撑钳。


Potter喷雾塔配有两个喷嘴,可产生中等雾滴及极小雾滴。精密喷嘴出厂时通过预设,通过恒定的25-35psi (1.7-2.1bar)空气输入,保证均匀的雾滴分散。

用户需要在当地配置一台空气压缩机(一般试验室常用型, 0-15psi )。

Product Description

Suitable for studying the biological effects of chemicals both when applied as a direct spray on the organisms or as a residual film. This design incorporates more recent developments from Rothamsted Experimental Station, Harpenden, Herts, England, including the following: quickly detachable atomisers pneumatically operated spray table and all air controls mounted on attached instrument panels. A 0-2 kg/cm2 pressure gauge is fitted as standard equipment.

Construction and Equipment Details

  • Frame: Manufactured from extruded Aluminium Alloy section in pleasing self colour finish of light and durable construction.
  • Spray Table: Precision made Aluminium Alloy spinning with high finish internally and matt external surfaces, positioned centrally by three screws mounted on the intermediate platform.
  • Nozzles: Units supplied in pairs as standard equipment for Intermediate and Final spraying. Manufactured to close tolerance giving an accurate spray formation, with stainless steel jet and pick-up tube. Fully adjustable assembly for level and centralising over the spray tube.
  • Spray Table: Adjustable for height within the piston of the air cylinder and fitted with eccentrics to the test platform for positioning the specimen dish beneath the spray tube.
  • Air Pressure: Constant supply of 1.5 – 2 kg/cm2 through the input connection controlled by an on/off switch and exhaust valve. Fine adjustment is made by a sensitive needle valve on the left hand side of the instrument giving direct reading on the pressure gauge, or manometer (which is supplied as an extra). This pressure operates the air jack and nozzle head simultaneously.
  • Manometer: Provision is made at the rear of the instrument to accommodate the use of a manometer if required. Level Four screwed feet in the base of the instrument provides easy levelling in conjunction with the spirit level on the intermediate platform.

Extra Equipment

  • Manometer
  • Portable Air Compressor complete with couplings and pressure valves
