WAEMING TABLE, Electrically Heated and Regulated, for warming slides in mounting paraf- 

 fine sections. Can also be used in fixing and hot staining. Constructed of a block of transite 

 24 inches long and 6 inches wide, mounted on a metal frame 3 inches high. A series of 

 resistance coils embedded in the transite furnishes the heat, the degree of which is controlled 

 by a thermo-regulator adjusted by a small knurled head at the side. A pilot lamp indicates 

 when the current is on and off. Any temperature can be obtained from 30 to 70C. Ship- 

 ping weight, 33 pounds. Complete with metal hood to protect slides from dust, thermometer, 

 connecting cord and plug for attachment to any 110-volt lamp socket $35.00 



MICROTOMES AND ACCESSORIES 



MICROTOME, Hand, intended for rapid class work or where expense is the chief considera- 

 tion. The object is placed in a clamp in the upper end of the tube, and is raised through the 

 hole in the glass plate by an accurately cut screw, which is entirely enclosed and protected 

 from dust and injury. The feed ia accurate and finely graduated. Each division represents 

 10 microns. The plate at the top over which the knife is drawn is 3 inches in diameter, mak- 

 ing a firm support for the knife without knife 7.50 



MICROTOME, Table, for all kinds of sectioning, including the freezing method. The object 

 clamp is placed in a vertically movable socket, held by hardened steel pivot screws in two 

 vertically swinging arms which are similarly attached to the main frame. The movement 

 thus provided for is regulated by a micrometer screw, with graduated disk and index plate. 

 The finest feed is 2^ microns. The knife travels on glass plates set in grooves in the metal. 

 These plates are extra long, so that the microtome knife will not be drawn off from the ends, 

 thereby endangering its edge. When equipped with a freezing attachment, it makes a very 

 satisfactory microtome for frozen section work. (See Nos. 8885 and 8886.) Without knife 15.00 



MICROTOME, Table, same as No. 8884, but with No. 8940 Freezing Attachment for Carbon 

 Dioxide 25.00 



MICROTOME, Table, same as No. 8884, but with No. 8942 Freezing Attachment for Ether 22.50 



MICROTOME KNITE, chisel blade form, with 88 mm cutting edge, for use especially on Nos. 

 >**4 to 8S86 4.00 



MICROTOME, Clinical and Diagnostic, for Hand Teed, provided with micrometer screw with 

 graduated or toothed head, each division representing 5 microns of feed. The hinged arm 

 carrying the knife is held rigidly in line by the solid metal frame preventing an uneven or 

 inaccurate cut. Complete with object clamp to take paraffine blocks up to 30x22 mm, but 

 without knife 19.50 



MICROTOME, Clinical and Diagnostic, for Hand Feed, same as No. 8892, but with freezing 

 chamber for carbon dioxide with needle valve to control the flow of gas. Will take objects 

 up to 30 mm in diameter without knife or object clamp 24.50 



MICROTOME, Clinical and Diagnostic, for Hand Feed, same as No. 8894, but with both paraf- 

 fine clamp and freezing chamber for carbon dioxide without knife 26.50
