Das Elektrische Reagenzglas-Kochgerät (Elektrischer Reagenzglas-Sieder) - transportables Gerät und Laborgerät ■The electric test tube cooker (electric test tube boiler) - portable device and laboratory device ■

ist ein mittels elektrischen Stromes gespeistes Kochgerät für Beagenzgläser, das sich aus einer feuerfesten Tonmasse mit Isolierschicht nach außen einschl. Sockel, den auswechselbaren Heizkörpern - ebenfalls aus feuerfester Tonmasse - mit ca· 6 cm tiefen Hohlräumen entsprechend dem Durchmesser resp· des Umfanges der handelsüblichen Reagenzgläser und Heizwicklung einschl. Buchsenkontakt, dem Anschluß für die iTetzstromquelle, der Heizstufenschaltung und einer Schaltung für jede einzelne Heizquelle zusammensetzt·is an electric current-fed cooking device for Beagen glasses, which is made from a refractory clay mass with an insulating layer on the outside including the base, the exchangeable radiators - also made of fireproof Clay mass - with approx. 6 cm deep cavities corresponding to the diameter or the circumference of the commercially available ones Test tubes and heating coil including socket contact, the connection for the mains power source, the heating stage switch and a circuit for each individual heating source

Gegenüber den bisher gebräuchlichen Kochstellen für Reagenzgläser (mittels elektrischen Stromes, Gas oder Spiritus u.a.) stellt dieses Gerät infolge der leichten Handhabung, der lediglich von einer Uetzstromquelle abhängigen Beweglichkeit ( - transportables Gerät^ und der Unabhängigkeit von einer Gas- resp. Spiritus flamme o.a. eine neuartige Konstruktion dar, die eine offensichtliche und darüber hinaus eindeutig zeitersparende Erleichterung und Vereinfachung des Kochvorganges in mehreren Reagenzgläsern zur gleichen Zeit ( - Laborgerät - ) bedingt.Compared to the previously common hotplates for test tubes (by means of electricity, gas or Spiritus, etc.) represents this device due to the easy handling, the mobility only dependent on a power source (- transportable device ^ and the Independence from a gas resp. Spirit flame o.a. a new type of construction, which is an obvious and, moreover, clearly time-saving relief and simplification of the cooking process in several test tubes at the same time (- laboratory device -) conditionally.

Claims

13/01.

Security claim

1 ·) The test tube och {: erut (electric beagent glass boiler) at the top is in a commercially available cooking device for test tubes powered by electricity from a Stroraes ₉ which consists of a fire-proof clay mass with an insulating layer on the outside including the base, the exchangeable heating elements - also axis refractory clay - with co · 6 cm deep cavities corresponding to the diameter res? · the circumference of the test tubes with heating coil and socket contact »the connection for the UotsstromcruGlle (Ho and 22o V ·)» the HeizstufonGchfiltung and a circuit for 3od, single Eoisquello

2) It is characterized by the fact that, due to its extremely simple handling and independence from a gas or alcohol source or similar, the Uetsotron source (Ho and 22o V), which is only dependent on Ginor (Ho and 22o V), is dependent on Boweglieh & eit (- the portable device in Zloinformnt s · 3 · for the doctor when visiting the sick with an exchangeable hot rod so and a clirnubbaren cover closure with test tube ·) for a * obviousea and one time-

sporendö Facilitation and simplification of the cooking process in very large test tubes at the same time (- that Itobor ^ erät -) z. B · in series examinations in medical and choral laboratories.
