描述：

25 mm Glass Holder with glass frit or with PTFE-coated screen support for hybridisation tests, particle testing and clarification.The two devices differ only in the filter support, the glass frit or the PTFE-coated screen support. The device with glass frit ensures uniform distribution of particles and is therefore recommended, when the retained particles on the filter surface are of intrest. The device with the PTFE-coated screen support is, as it is easy to clean, more suitable, when the filtrate is required, or for radiochemical work. The PTFE ring which holds the glass frit or the screen support allows autoclaving the devices with a filter in position, without stickage of the filter to the support, and also protects the rim of the glass frit from breakage and from potential leakage. It has a rim araound the upper edge, which simplifies the positioning of the membrane filter when inserted, and a silicone ring on the underside for a reliable seal on the filtrate side. The funnel-shaped top part simplifies filling in the sample
