(IT'S AIR-COOLED!)

By using ordinary air for cooling in-stead of costly conditioned water, BlueM's unique HUMIDAIRE Temperature!Humidity Chambers save thousands ofgallons of water (and hundreds ofdollars) a year.Yet, they're the most accurate andreliable units ever developed for long-term high temperature/humidity test-ing. Ideal for such steady state re-quirements as MIL-202C, Method 103B,Condition D - continuous operationfor 56 days. Control humidity from40O% to 98% (4 1/2%), temperaturefrom +120C. above ambient to- 930C. (-4-120C.).

Key to their performance is the in-herent reliability of independent wetand dry bulb POWER-O-MATIC 60®RProportioning Control Systems. Thispatented control assures straight-lineperformance, operates continuouslywithout attention almost indefinitely.If you want to save money, but needa quality, reliable temperature /humid-ity cabinet, remember the Blue MHUMIDIARE.

Digitize it!Now you can digitize signals at high speed, withhigh accuracy and high temperature stability-but at low cost. The BIOMATION/DATALAB Series700 Analog-to-Digital Converters use the succes-sive approximation conversion method and aredesigned to interface easily with all computersystems.The 710 is a 10 bit converter with a conversionrate, including sample and hold, of 200 kHz. The712 is a 12 bit converter with a conversion rateof 125 kHz. Multiplex inputs of either 2, 4, 8 oradditional increments of 8 up to a maximum of 64inputs are available as an option.The sample-and-hold circuit, with an aperturetime of only 20 nsec, ensures that the units meetthe accuracy requirement for high frequency in-put waveforms. During sampling, the circuit tracksthe input continuously until the hold command isreceived. At this time the conversion process isinitiated. This technique provides superior resolu-tion for high frequency inputs.Outstanding temperature stability of the con-verter is achieved by utilizing matched semicon-ductors and high stability passive componentsand power supplies. This method of temperaturestabilization ends the need for control ovens anddoes not depend on a uniform temperature acrossthe entire converter.The Series 700 offers additional features, too;such as: ± 1 V input; input impedance, 10 MQmin.; common mode rejection, 60 db min.; andlinearity, with low temperature coefficients overa 0-600C operating temperature range.All models are completely self-contained, fea-turing precision stabilized power supplies, dif-ferential input stage, sample-and-hold circuit,digital logic control, and neon binary displays.Prices are low: only $1650.00 for Model 710, and$2250.00 for Model 712.For complete technical information, write: Bio-mation Corporation, 1076 East Meadow Circle,Palo Alto, California 94303.

Any Fraction CollectorlThe Fractophorator, for gel electrophoresis, is designed for the separation of proteins, hemoglobin,albumin, enzymes and other compounds, using polyacrylamide or any other supporting medium. Itautomatically elutes in pre-determined amounts of buffer solution, individual bands emerging from theelectrophoretic column and delivers the fractions to a collector. The complete unit can be attached toany electrically driven fraction collector and is activated by the collector's timing system. Load capacityis from a few micrograms to 25 mgm in a 13mm diameter by 130mm long column. Price $570.00

Measurements in scientific and educational lab-oratories involving impedance magnitude, Z,and phase angle, 0, no longer require tedioustest procedures. These measurements are nowas easy to make as voltage readings. No nulling. . . no balancing . no calculations to make.The wizardry of these HP instruments providesdirect readout in terms of z (in ohms) and 0(in degrees) over a continuous frequency range.HP 4800A Vector Impedance Meter covers the5 Hz to 500 kHz range. You set the frequency,select the impedance range and read: z from1 ohm to 10 Megohms, and () from -90 to+90°. $1650.HP 4815A RF Vector Impedance Meter covers500 kHz to 108 MHz. Measures, via a probe,active or passive circuits directly in their nor-mal operating environment. 7Z from 1 ohm to100 K ohms; o from 0° to 360°. $2650.Application Note 86 describes many applicationsof the 4800A and the 4815A Vector ImpedanceMeters including the measurement of z.

New Worthingtoncatalog lists enzymes

for researchOur newly published catalog listsmore than 230 high purity enzymesand related biochemicals forresearch. Several are producedthrough the use of such advancedtechniques as column chromatog-raphy, disc gel and free-flow elec-trophoresis.The catalog provides essential

information on enzyme source,activity, purity, assay, packaging,and price for each biochemical.Also listed is a group of enzymaticreagents for clinical diagnosis.

At Worthington we insist on pre-paring all our own enzyme products,carrying them from raw materialthrough processing, purification, andpackaging. With complete controlover each step, we can give impor-tant guarantees of enzyme quality.Other suppliers - re-sale housesoffering something made by some-body else - can't do it.Use the attached coupon to request

Here's an Instrumentthat can makethe Gradient.

FORCHROMATOGRAPHIC ELUTIONOR FILLING ZONAL ROTORS

With a capacity of 3200 ml/hr, theModel 380 DIALAGRAD ProgrammedGradient Pump is especially suitedforfilling zonal rotors as well as form-ing liquid chromatographic elutiongradients and similar applications.Almost any two component gradientcan be formed by simply setting aseries of dials. There are no cams tocut or multiple solutions to mix atestimated concentrations. The shapeof the curve is determined by settingeleven 0 to 100% dials which repre-sent the initial, final, and nine evenlyspaced intermediate ratios.Thisgives10 program intervals, each of whichare automatically subdivided by fivelinear interpolations to produce asmooth gradient.

Calibrated flow rates from 1 to3200 ml/hr and program durationsfrom 5 minutes to 16 days are setwith positive stop switches. TheDIALAGRAD will produce linear orcurved gradients with equalaccuracy and the program will beperfectly reproducible run after run.The instrument takes but a fewminutes to program and requires noattention during a program run.
