Thank you for your inquiry.

For the 250 ml Soxhlet extractor, it is necessary to use an extraction cartridge large enough to accommodate the sponge in its entirety without compromising the extraction process efficiency. Since the sponge has a radius of 10 cm (100 mm) and a height of at least 10 cm, here’s the information:

• The 33×100 mm extraction cartridges may be suitable for housing only part of the sponge, but they will not be enough to accommodate it completely due to the mentioned dimensions.
• The largest available cartridge, 41×123 mm, would also not accommodate the entire sponge, as its dimensions are still insufficient to house it fully.

Unfortunately, none of the available cartridges for this 250 ml Soxhlet extractor will be large enough to accommodate the entire sponge.
