This Micro-Flow Pump is battery oper­ ated and has a capacity of 1 ml. Flow rates can be varied from 1 m l . / half hour to 1 m l . / 20 hours, with the rate determined by the resistor capsule used. The pump operates by electrolysis, generating a gas that moves a piston which drives fluid at a generally uniform rate. Extra bat­ tery packs and electrolyte are avail­ able and the pump can be re-used repeatedly. Model 085. Sage In­ struments, Inc., 2 Spring St., White Plains, Ν. Υ. 426

Gaussmeter

A new transistorized direct reading gaussmeter provides magnetic field measurements in eight ranges covering all fields from 0 to 100,000 gauss. The standard model, AL100G has a pre­ cision of 1%. The principle of opera­ tion involves the rotation of an ac­ curately wound wire coil at high speed by a synchronous motor. The output signal is directly proportional to the magnetic field and is read directly from a calibrated meter. Homogeneous or inhomogeneous fields may be measured, and temperature compensation is in­ corporated in the design. Alpha Scien­ tific Laboratories, Inc., P.O. Box 333, Berkeley 1, Calif. 427

DELTATHERM THERMOBALANCE The new Deltatherm Thermo­ balance, an accessory unit for the Model D 2000 Deltatherm, offers maximum convenience and versa­ tility for Thermogravimetric Anal­ ysis in chemistry, geology, metal­ lurgy, ceramics, and allied fields. The Thermobalance is the latest in a series of related instruments for use with the basic Deltatherm ther­ mal analysis system. The heart of the instrument is a precision balance of the null-type, which minimizes the effects of vibration. Enclosed in a gas-tight glass chamber, the balance may be operated in a vacu­ um or controlled atmosphere. Maximum recorder sensitivity is 2 micrograms per inch. This high sensitivity permits detection of low percentage changes in small samples.

This ability to analyze small samples provides : Maximum freedom from thermal lag. Maximum gas evolution in minimum time. Maximum freedom from thermal gradients in the sample. Standard with the Thermobalance is a 1250° C furnace, with a 1600° C furnace optional. The furnace is weight counterbalanced for operator convenience. Functionally designed, carefully tested, and ruggedly constructed for lasting accuracy by those expe­ rienced in the field of thermal anal­ ysis instrumentation, the Delta­ therm Thermobalance will prove a valuable addition to your laboratory.
