Foreword 



IN presenting this catalog for your consideration, we wish to call your attention to 

 some of its most distinctive features. No attempt has been made to prepare a 

 complete list of scientific laboratory apparatus and equipment as there are many 

 highly specialized forms of equipment to which only occasional reference is necessary. 

 This special apparatus is covered by separate pamphlets which are available at all 

 times. We have attempted to list all forms of standard equipment as well as those of 

 special design, for which there is a moderately general demand. 



THIS CATALOG IS A COMPILATION OF EXCLUSIVELY AMERICAN MADE 



GOODS AND IS A TRIBUTE TO THE PROGRESS MADE BY 



AMERICAN MANUFACTURERS 



We have elected to prepare a fairly complete catalog of convenient size, rather 

 than an encyclopedia of scientific apparatus, which would of necessity be so bulky as 

 to be unwieldy. 



In the selection and arrangement of .descriptive data and illustrations, we have 

 been guided by the requirements of those who may have occasion to use the catalog. 

 We have made an attempt to simplify the work of ordering our merchandise, wherever 

 it has been possible to do so, without sacrificing accuracy or necessary information. 



Each illustration shows either a standard type of apparatus or a characteristic 

 feature which may be adapted to your requirements. 



As a general rule, the articles described in this catalog are carried in stock for 

 immediate delivery. Other apparatus can be promptly secured or made up at a 

 reasonable cost. 



Reference to other catalogs will be understood by us and the specifications cor- 

 rectly interpreted. 



The utmost care is observed in checking and packing goods for shipment, and 

 every effort is made to avoid breakage in transit. All claims for loss, damage or 

 breakage in transit should be promptly filed against the carrier. We will assist in 

 every way possible, the adjustment of such claims. Any complaints will be promptly 

 and cheerfully investigated and complete satisfaction is assured. 



All prices are based upon actual market conditions and are subject to change 

 without notice. Fluctuations may be expected, but our prices will be consistent with 

 existing conditions over which we have no control. 



The cost of containers and packing will be charged at cost. Acid bottles, cases, 

 ^carboys and some drums are extra and returnable for full credit at our store or 

 warehouse. 



Our terms of payment are NET CASH 30 days, F. O. B. Chicago. 



Where no definite shipping instructions are furnished with order, we will use our 

 own judgment, and ship by shortest and cheapest route. All shipments are made in 

 compliance with Interstate Commerce Commission regulations. Parcel-post shipments 

 will be made wherever possible, with a small charge for insurance. 



Conditions arising out of the war require our customers to obtain licenses for 

 the purchase of ethyl alcohol and certain chemicals classified as explosives. Whenever 

 such materials are ordered, it is imperative that certified copies of license accompany 

 the order, as shipments cannot be made until such certificates are received. 



Our GLASS BLOWING DEPARTMENT is adequately equipped to repair and 

 make up all kinds of standard and special apparatus, either plain, graduated or ground. 



Our BALANCE and INSTRUMENT REPAIR DEPARTMENT has been or- 

 ganized to inspect and repair any imported or domestic balances and instruments. 

 We take great pride in our ability to render this service and guarantee all work of this 

 nature. 



We wish to thank our friends and customers for their past consideration and hope 

 that it will continue. We solicit all inquiries, and no order is too small to receive ur 

 most careful attention. 



Our organization has been planned for SERVICE. It is at your disposal. 



Faithfully yours, 



A. DAIGGER & COMPANY. 

 Chicago, January. Nineteen-Nineteen.
