The CHROMAFLEX Glass Reservoirs are ideal for packing gel slurries into columns ��nd as buffer reservoirs for simple gravity flow chromatography. Each reservoir has been designed for easy mounting on all CHROMAFLEX Columns. The reservoir capacities are matched by column ID to take the amount of slurry required to pack the longest standard column. The reservoir end fitting has 1/4-28 threads for simple flangeless connection to a pump. The Chromaflex Packing Reservoirs are ideal for packing gel slurries into columns. Each packing reservoir is designed for easy mounting on the Chromaflex Columns. The capacities are matched to take the amount of gel slurry required to pack the longest column. The packing reservoirs may also be used as a buffer reservoir for gravity flow chromatography.

���飺420836

CHROMAFLEX Flow Adapters allow easy adjustment of the column bed volume. They are ideal for concentration ��nd pH gradients, reverse flow separations, ��nd gravity flow separations that require a high level of resolution ��nd reproducibility. Flow adapters are available for all three standard ID columns. Flow Adapters improve chromatogram resolution by delivering the sample ��nd buffer directly to the top of the gel bed. This protects the gel bed from disruption during sample loading ��nd eliminates any dead volume above the gel bed. Flow adapters are recommended when using buffer gradients, during reverse flow applications, ��nd for high resolution gravity flow separations. Each flow adapter is supplied with a 20 µm porosity HDPE bed support, TFE/propylene o-ring seal, stainless steel adjusting rod, PTFE body ��nd 5 feet (1.5 meters) of FEP Teflon® tubing. Use of aggressive organic solvents requires the accessory PTFE bed supports ��nd Kalrez® o-rings listed.

���飺422530

The connection between the sprayer head ��nd the flask is made with a special screw thread ground joint, connecting cap ��nd loosening ring. If the joint ever "freezes" from reagent crystallization or residue formation, simply unscrew the connecting cap back onto the unique loosening ring ��nd the joint will easily come apart. These sprayers will operate on as little as 1 psi (0.07 kg/cm²) air pressure with optimal results at 3-5 psi (0.21-0.35 kg/cm²). The connecting cap, loosening ring ��nd o-ring should be removed before autoclaving.

TLC Spotting Capillaries, Borosilicate Glass, Microcaps®

��;������ɫ�V�á�

���飺764500

Microcaps® are ingeniously simple in concept ��nd in use. They are precision-bore glass capillary tubes, cut to predetermined lengths, so that each capillary tube will hold a known volume of fluid when filled. Microcaps are so inexpensive that it is not impractical to dispose of each tube after use. Filling is simple. Capillary action - not externally applied suction - draws the fluid into the tube. To dispense the fluid, simply squeeze the bulb. No unusual skills or training required. Immediate, professional results. Ideal for spotting preadsorbent TLC plates. Supplied in packages containing one bulb assembly ��nd one dispenser vial with 100 micropipets. Volumetric tolerance is ± 1%
