New Kjeldahl

New from Tecator, and available inthe USA and Canada exclusively fromFisher: a fully automatic distilling unit.The Tecator 1026 Kjeltec distilling unitis microprocessor-controlled. Simplypress one button, and the built-in steamgenerator automatically starts up, fullyready in two minutes.

The unit handles macro and microtubes with equal ease. The tube's con­tents are automatically diluted at thestart of the cycle by the built-in waterpump. Before distillation stops, thereceiver vessel is automatically lowered,the condenser outlet is thoroughlyrinsed, and any back-suction of distil­late into condenser is prevented.

The unit is designed to give accuratereproducible results in safe, convenient,unattended operation. Alkali-resistantmaterials are used throughout, tominimize maintenance.

"Wireless" Monitor System

A new "wireless" monitor systemconsisting of one Central Receiver unitand up to 99 Remote Transmitter units,can monitor all types of refrigeration,air conditioning, heating, and process­ing equipment, as well as doors, win­dows, safety devices by transmittingcoded signals through a building'sexisting power wiring.

Called the PCI Sentry Monitor, thesystem enables the user to plug oneCentral Receiver unit into any standard110 volt AC wall receptacle and fromthat location, monitor up to 99 itemsthroughout the building including coldrooms, roof compressors, boilers, con­veyor lines, and bin levels.

The system operates by detecting theclosure of virtually any type of switch

(such as a pressure sensor, temperaturesensor, or level sensor) which is eitherexisting or installed on the item to bemonitored. Small Remote Transmittersare wired to these switches with twoleads, then plugged into any standardwall outlet. The Remote Transmittersends a coded Signal to the CentralReceiver which flashes a number ofidentifying the item, enabling the userto correct a potentially critical problem.

Automated Microassay System

A new automated microassay systemfrom HP Genenchem delivers reprodu­cibility at every step of the microassayprocess, from sample introduction tofinal report.

All system modules are orchestratedthrough the HP Vectra personal com­puter to ensure the accurate, repeata­ble execution of a microassay method.

According to HP Genenchem, thesystem will be used by biotechnology,pharmaceutical, and food and beveragelaboratories that need to automate exist­ing ELISA methods. Installation of thesystem takes only one day.

Automation of the microassayprocess allows the system to controlmany of the random inaccuracies com­monly involved in biochemical assays.

Stir Cooker

Two years of development hasproduced a small stir cooker that dupli­cates the action of large steam kettlecookers. The one quart capacity allowslaboratory technicians to mix sample, orsmall test batch quantities, therebyincreasing efficiency and reducingmaterial waste. By eliminating constantattention of the technician, productivityis increased and labor savings of 60%have been reached. This equipment hasbeen service tested in a professionalfood laboratory.

Features include stainless steel con­struction and simplified operation. Theremoveable double boiler and self­adjusting agitator snap out for easycleaning. The high-reliability motor hastwo speed ranges with infinite variabil-
