These 25mm diameter PYREX® coarse porosity (40 to 60 µm) fritted thimbles are designed for use in PYREX® Soxhlet extractors when it is desirable to weigh the material extracted or where paper thimbles may be attacked by the chemicals used. These short length thimbles are only 85mm long. For PYREX® extractors and extraction apparatus, see Nos. 3740 through 3880. For more information on fritted products, please check the Guide t…

These microfiltration components are designed for the filtration of aqueous liquids. They may be used for the filtration of cell culture media, buffers or for particulate analysis of water samples. Units have coarse porosity frits, and accommodate 47mm filters. The components are interchangeable with competitive product offerings. Apparatus includes: 300 mL funnel, 47mm fritted glass support base, aluminum clamp and #8 silicon…

This 300 mL graduated funnel, 47mm is designed for assembly with the fritted glass support base, Cat. No. 33972-B.

This 47mm fritted glass support base is designed for assembly with either the 300 mL graduated glass funnel, Cat. No. 33971-300 or 1000 mL graduated glass funnel, Cat. No. 33971-1L.

This 1000 mL PYREX® Erlenmeyer flasks have 40/35 Standard Taper joints. Their uniform wall thickness provides the proper balance between mechanical strength and thermal shock resistance. For convenience, these flasks are graduated to show approximate capacity. An extra large marking space is also provided. Reference: ASTME-123.
