A Day in the Laboratory: Weighing Experiment(ENG/ESP)
Hello hivers, today I arrived at the laboratory where I work and I had to weigh tomorrow to melt.

 Weighing is a very important step in the laboratory and you have to take into account many features when weighing, and if it is with analytical balance, you have to be much more careful and better handling. If we want to achieve a special precision and accuracy, we must take into account several external factors before weighing, such as the temperature where the balance is located, humidity, and the container where you are going to weigh can not be plastic or aluminum because it could damage the balance.
 Also keep in mind that when you weigh, you have to put the container in the center so that the scale gives you the exact weight.

Well, today I weighed lithium metaborate. This is a flux that is used to melt the samples and adds viscosity and contributes to a better complete melting of the samples. In this technique you have to weigh 1.5 grams of lithium metaborate and 0.15 grams of the sample. This is poured into a porcelain crucible and labeled with the numbers of the samples to be measured.

 At the moment the power is out and I have not been able to weigh the samples, only the metaborate. Hopefully it will come soon, I will let you know jj.

Thanks and best regards hivers.

Hola hivers, hoy llegué al laboratorio donde trabajo y me tocaba a pesar de mañana fundir.

Pesar es un paso en el laboratorio muy importante y hay que tener en cuenta muchas características a la hora de pesar, y si es con balanza analítica, hay que tener mucho más cuidado y mejor manejo. Ya que si queremos alcanzar una precisión y exactitud especial, debemos tener en cuenta varios factores externos antes de pesar, como la temperatura donde está ubicada la balanza, la humedad, y el recipiente donde vas a pesar no puede ser plástico ni aluminio porque podría dañarse la balanza.
 También hay que tener en cuenta que cuando uno pesa, hay que poner el recipiente en el centro para que nos dé la balanza el peso exacto.

Bueno, en el día de hoy pesé metaborato de litio. Este es un fundente que se usa para fundir las muestras y le aporta viscosidad y contribuye a una mejor fundición completa de las muestras. En esta técnica se tiene que pesar 1.5 gramos de metaborato de litio y 0.15 gramos de la muestra. Esto se echa en un crisol de porcelana y se rotula con los números que tienen las muestras a medir.

 En estos momentos se fue la luz y no he podido pesar las muestras, solo el metaborato. Esperemos que venga pronto, ya les diré jj.

Gracias y saludos hivers.
