Flow control adapter comes with 0-4mm high vacuum PTFE valve with metering tip to adjust the air flow. The O-rings are completely enclosed with thin layer of PTFE around the high vacuum valve. This new design makes it inert to most chemicals/solvents used in column chromatography. Adapter has standard taper inner joint of 24/40.
General purpose column has solvent reservoir of 250 mL, Teflon stopcock and a top 24/40 outer joint. Fritted disc with coarse porosity to support Column packing, such as silica gel, Effective length: 10 in, ID: 20 mm, OD: 26mm.
This convenience pack includes 4mL clear vials and black polypropylene 13-425 screw-thread caps with septa. Vials are manufactured from Type 1 borosilicate glass. Vial kits are tested and guaranteed to meet or exceed critical performance parameters. Ideal for use with Agilent, Shimadzu, Beckman, Gerstel, as well as other 15x45mm vial format autosampler...
Three-neck round bottom flask with standard taper outer joints of 14/20 on both the center neck and angled side necks. Heavy wall design increases mechanical strength.
The upper vapor tube prevents the film or form migrating directly into the condenser. Top Outer Joint: 24/40; Bottom Inner Joint: 24/40. Capacity: 250mL.
Two-neck round bottom flask with standard taper outer joints of 24/40 on both the center neck and angled side neck. Heavy wall design increases mechanical strength.
