What is Purging? Purging refers to the removal of air/gas from a closed system, such as lab equipment by using pressure, purging gas or a vacuum. An air purging component eliminates air/bubbles from the equipment, which not only reduces the risk of contamination but also prevents loss of the liquid reagent. For this purpose, manufacturers […]
What are Heterogeneous Samples? A mixture is defined as a combination of two or more substances, which may or may not be chemically combined. A mixture can be either heterogeneous or homogeneous depending on the extent to which the substances are combined, as well as the uniformity of composition. A homogeneous mixture has a uniform […]
What is Dispensing? The term ‘dispensing’ in Bottle Top Dispensers refers to discharging of defined quantities of a liquid substance. In order to facilitate easier, quicker and more accurate dispensing of chemical reagents, researchers are widely using bottle top dispensers. This instrument has essentially replaced the method of pouring liquids into graduated measuring cylinders. Bottle […]
Using a Pipette filler Back in the day, the glass pipette used to be filled by sucking through the mouth, a phenomenon known as ‘Mouth pipetting’. However, mouth pipetting has been prohibited since long for the obvious safety reasons. Manual pipettes are usually filled using a manual pipette filler. On the other hand, we also […]
What are the Different Types of Burettes? Burettes are long, calibrated glass tubes that are used to dispense and quantify a wide variety of chemical solutions. The instrument has a stopcock on its lower end with a stopcock valve attached to it. The valve is used to control the amount of liquid flowing through the […]
