FI45XX – Sealing rings for different foaming methods and liquids

The available sealing rings (the figure to the left shows a selection) are required respectively for foaming using gas flow or a stirrer or for manual foaming-up. You can also prepare your measuring instrument for analyses of different types of liquid samples with the choice of the sealing material.

FL4501 ~ FL4504 – 不同孔径的玻璃滤板(直径50 mm)

不同孔径的50mm玻璃滤板组使您可以影响泡沫的气泡尺寸,并优化根据不同发泡性和泡沫稳定性范围进行的分析。该材质与几乎所有的液体接触都是呈化学中性的。 可选的TO4501清洁组确保延长其使用寿命。滤板与SH4501量柱支架和所有内径为40 mm的量柱兼容。

以下孔径的滤板支持单独订购:

  • FL4501:100至60 μm
  • FL4502:40至100 μm
  • FL4503:16至40 μm
  • FL4504:10至16 μm

FL45XX – Glass filter plates in stainless steel sockets with different pore sizes and diameters and for different liquids

FL45XX – Glass filter plates in stainless steel sockets

You can use a large variety of filter plates (figure to the left shows a selection) for foaming-up your samples by sparging. All of them have a glass filter, which is embedded in a stainless steel socket that makes inserting the filter into the sample holder very easy. With different defined pore sizes ranging from large to extremely small it is possible to create different bubble sizes depending on the foaming process to be investigated or adapted to the foamability of your sample. The diameter of the filter plate is either 30 mm for the standard-sized measuring columns or 14 mm for columns that are used for small sample volumes. Depending on materials used for embedding the filters, they are appropriate for different kinds of liquid.

The following filters are available1:

FL4511 ~ FL4514 – 不同孔径的玻璃滤板(直径24 mm)

对于内径为20 mm的量柱,我们提供直径为24 mm的各种玻璃滤板,其中大多数是化学中性的,用于小量样品发泡。您可以利用滤板孔径影响气泡尺寸,并根据不同的起泡性和泡沫稳定性范围进行分析。使用滤板时,需要配备PA4504适配器。


以下孔径的滤板支持单独订购:

  • FL4511:100至160 μm
  • FL4512:40至100 μm
  • FL4513:16至40 μm
  • FL4514:10至16 μm

FL4520 – 滤纸(100片)

在严重污染样品的情况下,特别推荐使用FL4520滤纸进行发泡。滤纸的包装内含100片。该滤纸由化学纯纤维素制成,与内径为40 mm的量柱兼容,无需切割,可与大多数液体一起使用。孔径为12至15µm,与玻璃滤板FL4504的孔隙度大致相同。

使用滤纸需要两个FI4501密封环和一个额外的FI4504密封环。

FL4551 – Paper filters (1,000 pieces)

FL4551 – Paper filters (1,000 pieces)

The use of a FL4551 filter paper is particularly recommended for foaming in the case of severely soiling samples. The filters are available in pack sizes of 1,000 pieces. The paper is made of chemically pure cellulose, is compatible with our measuring columns with an inner diameter of 40 mm without having to be cut to size and can be used with most liquids. The pore size is 12 to 15 µm, about the same porosity as our FL4534/FL4538 glass filters.

The use of a paper filter requires a filter holder FL4550.

HC10 – 湿度箱

表面的润湿性受气候环境条件的影响。湿度箱HC10与温控箱TC30 / TC40结合使用使您能够在精确控制的湿度和温度下测量接触角。

在温度高于50°C,湿度高于65%时,建议使用配选的绝缘罩TC3200(底图)。该罩有助于更快达到目标湿度,并以更高的稳定性保持目标湿度。

     

  • 相对湿度(无绝缘罩):22°C时为15 - 85%,在10 - 15°C时高达89%,在70 - 90°C时高达5%
  • 达到目标值的时间:20 - 300秒
  • 需要外部压缩空气供应(3-6 bar,非常干燥的空气),可以提供适用压缩机。
  • 温度范围介于5至90°C(提供适用温控器)
  •  

IL10 – 附加冷光源

在某些情况下(如非反射或不均匀的样品),滴液的图像不能从背景中充分显现出来。在这种情况下,为了改进分析,借助于冷光源IL10可以对样品增加照明。灯的灵活曲线设计和光强度微调功能能够调整光照方向、入射角度和亮度,以适应特定情况。
