it's the most in pre-coated T•L•Cplates

MANY PEOPLE IN LABORATORIES THE WORLD OVER USE THIS T-L-C PLATE TO IDENTIFY AND SEPARATE COMPOUNDS IN A VERY SIMPLE, EFFICIENT WAY!

9 Yes, because a new era in Thin Layer Chromatography is start­ ing. Until now pre-coated TLC plates offered convenience, only. MANNOGRAM offers convenience AND accuracy. And repro­ ducibility, too. So that you can use it everywhere. In the research laboratory, in clinical laboratories and in Quality Control. To separate complicated, closely related mixtures. # The absorbent thickness of each MANNOGRAM plate is 250 microns. Always. Because it is electronically controlled. And it arrives highly activated in your laboratory. Because each plate is packed hermetically after activation. Just peel-off the plastic cover, and yoir have your high resolution plate ready to use. Our spot­ ting guide is supplied for additional convenience. • MANNOGRAM is available in sizes of 5 χ 20 and 20 χ 20 cm and with three absorbents: Silicagel (with inert polymer binder), Alumina and Microcrystalline Cellulose. With or without fluorescent indicator. Try our plate and you will never want to use anything else. And we have something nice for your Purchasing Depart­ ment too: Our low prices.

KLETT PRODUCTS

KLETT COLONY MARKER AND TALLY. For the rapid and accurate counting of colonies. Marks and records at the same time, leaving per­ manent record for rechecking. When all of the colonies in an area or dish have been marked, the tally is read and then is reset to zero with the reset knob. Plates that would be considered too crowded for counting by the usual method can be counted easily with this instrument. The counting opera­ tion can be interrupted at any point without caus­ ing errors. Complete with pen and extension cord. For operation on 115 volt, A.C., 60 cycle.

KLETT BIO-COLORIMETER T h e visual color­ imeter illustrated presents a num­ ber of outstand­ ing features mak­ ing it ideal for c l i n i c a l or r e ­ search work. Built on the most modern mechanical and op­ tical principles it is widely accepted for accuracy and dur­ ability.
