Early work with Peltier elements for knowing technology started in the early 80’s but it was not until when the first incubator finally hit the market as a world premiere, running only by Peltier elements. Furthermore, the possibility of creating a thermal flow directly from an electrical current makes the use of gases such as freon useless, as they are harmful to the ozone layer.

Bidirectional serial RS connection for temperature recording and digestion program edition with RAT connected to a computer. Sometimes distillation is required to be extended, which produces more water but this does not alter the results when making the titration. Safety door that prevents distillation with door open.


Digestion time should be determined depending on the amount of recovery by using known matrix samples. The digested mixture is neutralized with a base and distilled later.

To study the quantification limit, we work with ammonium sulphate standards, tritant reagent HCl 0. Boric acid reservoir capacity: This range includes the value Nowadays, any laboratory working in a quality environment must demonstrate reliability of the data generated. The Peltier effect is characterized by the occurrence of a temperature difference between two sides of a semiconductor when a current flows through it.


Calentamiento uniforme del bloque de aluminio. Prepare the solution of the following formula for 1 litre of fixative solution: The distillation speed varies with the condenser cooling capacity and with the capacity of generating heat from the heater.

Besides being totally quiet, they have a very small size and weight, and they can easily handle bumps and vibrations, they can be used in any position, vertical, horizontal, inclined and also, thanks to them, cooling capacity can be adjusted by simply varying the feed stream. Results obtained are shown in the following table: The equipment provides satisfactory results working with standards in the range between 0.

Deionised water milli-Q quality. It also has a very complete alarm system. Selecta has tried to be aware of the latest technologies and methodologies in the field of laboratory equipments. A wastewater sample has been tested from a comparison between laboratories.

These exist in a combination with carbohydrates or lipids, which may be physical or chemical. The method consists of three stages: La mezcla resultante se neutraliza con una base y se destila. Now the sample has the characteristics of a stable wine and this conductivity is the one which has to be taken into account. Initially, the evaluation end point was detected by means of an indicator colour potenciometrai later on, the automatic values were introduced with the detection of the evaluation end point by potentiometry.


In fact, quite boric can be added aplicaiones ensure the complete absorption of ammonia. Slowly dose 50 ml of distilled water in each sample tube be careful of the reaction violence.

Only for information, please find below a relation of the different programs used for the different materials to be sterilized:.

SELECTA offers a wide range of desktop, for dentistry and medicine, laboratory autoclaves being able to choose between manual purge, atmospheric or vacuum models, from which we highlight the following laboratory autoclaves: The low concentration level ad1 sample is daily prepared from acetanilide standard and milli-Q water.

Bidirectional RS serial connection for temperature recording and digestion program edition with RAT connected to a computer. It is an analytical essay consisting of a quick precipitation of tartrate crystals, potassium acid, which are supersaturated in the wine.

Specially designed to absorb and neutralize acid gases generated in Kjeldahl digestion processes.
