The explosion-proof Rotavapor115EX is Buchi/Brinkmann's inno-vative solution to the hazard posedby sparking electrical motors whenworking with highly-volatile materials.

The Rotavapor 115EX has noelectrical components whatsoever.Instead, its high-torque, variablespeed motor is powered bycompressed air. Simplyconnectthe 1 1 5EX to any air source of 20-1 00psiand evaporate in safety at speeds from15 to 270 rpm. Like the electrically-driven BOchi/Brinkmann standardmodels, the 115EX comes equippedwith 1 liter evaporating and receivingflasks and is available with V-stand, quick-action jack, heating bath and a wide selectionof other accessories.

BOchi/Brinkmann RotaryEvaporators are unsurpassed inversatility, durability, andsafety of operation. Inaddition to the115EX, there areeleven electrically-powered models to meet every concentratingneed, from 5ml to 50 liters or more (Pilot Plantmodels). Our new brochure describes them all.Just write: Buchi Division, Brinkmann Instruments,Inc., Cantiague Road, Westbury, N.Y. 1 1590.In Canada: 50 Galaxy Blvd., Rexdale, Ont. M9W 4Y5.

Affi-Gel® BluetRemoves albumin from serum.}f

Purifies enzymes.

Bio-Rad's Affi-Gel Blue, made bycoupling a blue dye to crosslinked Bio-GePt'agarose beads, is a highly effective affinitychromatography matrix -supplied ready-to-use! Affi-Gel Blue's strong biospecific affinityfor nucleotide-requiring enzymes makes itideal for purifying kinases, dehydrogenasesand more than 30 other nucleotide-bindingenzymes.

Another major application for Affi-GelBlue is the removal of albumin from plasmaand serum. Using a simple column tech-nique, Affi-Gel Blue will remove over 95%of the albumin from serum with little non-specific adsorption of other serum proteins.The two dimensional electrophoresis patternsbelow show this clearly. The pattern on theleft, with the large band of albumin, is humanserum. The pattern on the right is that sameserum pool after passage through an Affi-Gel Blue column.

Bio-Rad supplies Affi-Gel Blue in 50-100mesh for albumin removal and 100-200 meshfor enzyme purification. It costs only $49.50for a 100 ml bottle of either mesh size, readyto use.
