Improve the discharge accuracy with a temperature controller! What is the role of warmth in Dispenser?

The equipment that regulates the temperature of the liquid agent is expressed in various expressions such as heating system, temperature control system, temperature control system, heat control system, and heat control system. We will explain what role this temperature controller plays.

What can you do with a temperature controller?

First of all, our temperature controllers are broadly divided into "heat type temperature" and "Peltier type temperature".
"Heated temperature control" is used to increase the temperature of the liquid agent. On the other hand, "Peltier temperature control" can be both increased or lowered, so it is used to maintain liquids at the desired temperature.

Tips

The Peltier system

The Perche element has the property of cooling one side (heat absorption) and heating the other side (Perche effect) when the current flows. Taking advantage of this characteristic, the method of cooling and heating around the syringe is called the Peltier-type temperature tone. In particular, when cooling syringes, fans and air are used because the heat generated on the other side needs to be effectively dissipated.

Features of heating type temperature tone

The main purpose of using heated temperature control is the following two.

➀Reduces the viscosity of the liquid agent and improves the vomitability

When expelling liquids with high viscosity, it may take some time to discharge them as they are, or it may not be possible to apply with the desired amount or shape. Heated temperature tone can effectively reduce the viscosity by properly warming the liquid agent, making it easier to discharge.

It is also effective in reducing threading

In many cases, viscosity is also related to "treading" that is likely to occur when discharging liquids. If the viscosity is too high, the liquid agent is less likely to break when the discharge is finished, and it is more likely to occur that thin threads are pulled. By adjusting the viscosity appropriately by heating, this threading can be suppressed and the risk of defective occurrence in the post-process can be reduced.

②Eliminate discharge problems due to low environmental temperature

“We were able to discharge without problems in the test environment, but for some reason it doesn’t work at the actual manufacturing site.…"There are many cases in which environmental temperature has a significant effect on the background of such problems. In particular, when the environmental temperature at the site is low, such as in winter or cold regions, the viscosity of the liquid agent increases.
By introducing a heated temperature control system, it is possible to keep liquids at a constant temperature without being affected by the environmental temperature of the site. As a result, it maintains stable discharge performance regardless of season or place, leading to improved productivity and quality stabilization.

Features of Peltier-type temperature

The biggest advantage of the Peltier temperature control system is that it has both "warm" and "cool" functions.
The main purpose of using Peltier temperature control is the following two.

①Maintaining a constant temperature of the liquid agent improves the discharge accuracy.

The room temperature at the manufacturing site always changes depending on the season, time of day, and availability of air conditioning equipment. This change in room temperature affects the temperature of the liquid agent itself and causes fluctuations in viscosity. For example, if the room temperature rises, the viscosity decreases, and the discharge volume may increase. Conversely, if the room temperature drops, the viscosity will increase and the discharge volume may decrease. In response to such changes in the external environment, the Peltier system allows for precise temperature maintenance in an integrated manner of heating and cooling.
In addition to the effects from the external environment, it is also effective against heat generation inside the syringe (e.g. chemical reaction heat of adhesives, etc.) is a major feature of Peltier-type temperature control with cooling functions.

②Controls the temperature of the liquid agent lower than the environmental temperature and suppresses the change in the condition of the liquid agent.

If you want to minimize the impact of the change in viscosity of liquid agents

We propose a volumetric Dispenser MPP series.
The MPP series is Dispenser, which is characterized by "quantification" that is less susceptible to changes in liquid viscosity.
Even if the "viscosity" of the liquid agent changes, the "crush" (volume)" to be exhaled is always kept constant, so it is possible to provide a stable and accurate amount.
In order to control the amount of discharge according to the amount of movement of the plunger, a certain amount of discharge is performed regardless of the liquid viscosity.

Utilization of MPP series: Responding to factors other than viscosity changes due to temperature

The cause of dissipation is not always limited to changes in viscosity due to temperature. For example, whenever a lot of liquids (manufacturing number) changes, there may be slight variations in liquids viscosity.

Examples of variations between liquid lots

Even in cases where the discharge volume increases or decreases due to such "variability between liquid lots", the MPP series, which accurately measures the volume of liquid agents, will be effective. It is not affected by the difference in liquid viscosity of each lot, but always emits a fixed volume set, so it is possible to maintain a stable discharge volume.
