New*— ECONO-COLUMNS -«
from BIO-RAD Laboratories
ft SHUR
In this day and age of high prices Bio-Rad happily announces a bargain —quality chromatographic columns for as little as 98 cents each in quantities of 200. Even our most expensive 50 cm ECONO-COLUMN™ (non-jacketed) costs only $5.93 in that quantity. Now more good news. The performance characteristics of ECONO-COLUMNS—flow rates, band broadening, reuseability—equal or exceed those of competing col-umns costing more than twice as much. Proof of that? Request our Bulletin 1029.

ECONO-COLUMNS come in 4 diameters (0.5, 0.7, 1.0 and 1.5 cm ID) and in lengths up to 50 cm. They are constructed of borosilicate glass with polypropylene end pieces. A complete series of jacketed ECONO-COLUMNS is also avail able at competitive prices. Bio-Rad recommends ECONOCOLUMNS for a wide range of laboratory separation techniques in cluding ion exchange, gel filtration, adsorption and affinity chromatog raphy. All columns operate by gravity flow; they function from cold room to well above ambient temperatures.
For your convenience in working with ECONO-COLUMNS, Bio-Rad offers a number of useful low-cost acces sories. These include a 3-way nylon stopcock that fits all column sizes (economy again); one filling funnel fits all columns; 2-way stopcock with Tef lon metering valve and flangeless fittings for use wtih Teflon eluant and effluent tubing. Many are standard with jacketed columns. Bulletin 1029 gives complete descriptions, documentation of performance, and prices. Call or write Bio-Rad or circle the reader service number.
