Analytical Balance

Analytical Chainomatic Balance No. 15

A most efficient and serviceable balance for routine laboratory work.

 

Capacity 200 grams.
Sensitiveness 1/20 mg. with 100 gram load, (1/10 mg. with full load.)
Column Graduated, column and vernier, reading from 1/10 mg. to 100 mg. No riders or small weights required.
Beam 15 cm. (6") long, sawed from hard rolled special aluminum alloy, having great tensile strength and uniform density. Will sustain full load without flexure and maintain adjustment through varying temperature changes.
Knife Edges Agate
Bearings Agate planes. All edges are entirely freed from the bearings, when the balance is arrested.
Releasing Mechanism Fall away type, a simple and effective arrestment for beam and agate edges.
Pans Nickel silver, 6 cm. (2 3/8") diam.
Bows Nickel silver, 10 1/4 cm. wide by 20 cm. high inside. (4 1/8" x 8".)
Pan Arrest Independent arrest for pans with stop.
Case Dimensions over all 16 1/2" long, 9 1/4" deep, 18 1/2" high. Polished mahogany, with glass sides and top, front sliding door counterpoised, rear door removable. Mounted on black plate glass. With vial levels and leveling screws.
Measurements 30" x 16" x 25".
Net Weight 23 lb.
Shipping Weight Domestic, 70 lb.; Export, 72 lb.
Code Word ANNOUNCE.
Code Word Balance with Movable Index, "Auto-Dex" ANNODEX.

Analytical chainomatic balance No. 9

RIDERS AND FRACTIONAL WEIGHTS UP TO 100 MG. ELIMINATED
WEIGHING IN ANALYTICAL CHEMISTRY COMPLETELY REVOLUTIONIZED
RELEASING MECHANISM  (BEAM ARREST)   (Patented)

The special construction of the beam arrest not only insures the positive alignment  of the agate edges with their respective bearings, but is so designed that the center agate knife edge is directly over the center of the column. This is of great importance when the balance is loaded to full capacity and where the greatest precision is required. The beam arrest arms and the beam being pivoted about a common axis, the supporting points of the arrest arms move through the same arc as the supporting points of the beam, so that contact between edge and bearing always remains the same, thus the acme of balance construction is reached, the shifting of the beam with the consequent dulling of the agate edges rubbing over their respective bearings being entirely precluded.


Combined assay and analitycal balance No.B

Details

COMBINED ASSAY AND ANALYTICAL BALANCE No. 1-B

Specifications same as No. 1A (see page 5) but in addition to the assay hangers, also provided
with 1 pair of aluminum bows and loose aluminum pans, for analytical work.

 

Capacity 25 grammes
Sensitiveness 1/50 mg
Speed Indicator swings 20 index divisions, each 1 mm. wide, in 10 seconds. An excellent balance for silver assaying, carbon weighing in iron and steel analysis; also used as a precision analytical balance.
Beam Sawed from hard rolled aluminum, great tensile strength and uniform density. Will retain adjustment through various temperature changes. 8 in. long, graduated on the right-hand side in 50 divisions, 0 in the center to 50 directly over the end knife edge. Riders weigh 1 mg., each division corresponding to 1/50 mg.
Knife Edges Agate
Bearings Agate
Hangers Nickel silver, skeleton type
Pans 1 1/8 in. diam., oxidized black, so that the smallest particle can be easily seen
Bows 2 in. wide
Pans Aluminum, removable, with handles, 1 13/16 in. diam., 1/2 in. deep.
Case Polished mahogany, with counterpoised sliding sash. Glass top, sides and back. Leveling screws and level. Dimensions: 15 1/2 in. long, 8 1/4 in. wide, 13 in. high.
Shipping Weight Domestic, 45 lb.; export, 50 lb.
