The Process Of Precision Dispensing

Dispensing is the act of transferring liquid or gas from a vessel or container to a receiving substrate. Chemical reagents, medicines, sterile and distilled water and liquefied gas are some of the materials that require precision dispensing. Precision during dispensing refers to the ability of ensuring that only the required volume of the liquid or gas is transferred from the source to the receiver. Such precision must be observed even to the tenth of decimal value. Below are several considerations for the process of precision dispensing.

Personnel competence. Fulfilment of the requirements of precision dispensing is crucial in the medical field, manufacturing industries, laboratory experimentation and pharmaceutical procedures. Accordingly, these scientific areas rely largely on the skills of the employees who will execute the dispensing procedures. Such aptitude must have been a product of the personnel’s education, experience and continuous exposure to dispensing instrumentation seminars and trainings. Without this factor, any machine or instrument for precision dispensing won’t be appropriately utilized.

Abbreviations and zeroes. In delivering required volumes of reagents or fluids, the personnel must be fully aware of the interpretation of units and related numerical values. For example, if a nurse will fail to notice one decimal value from a given medicine dosage, this would mean that the patient would receive ten times stronger dosage of the antibiotics than what is required. Along with this, laboratory analysts who will transfer less volume of reagent to a mixture due to missed out zero values might incur erroneous results. Hence, precision dispensing involves accurate interpretation and observation of analytical entries.

Instrument suitability. Nowadays, a wide range of dispensing instruments is made available for businesses and laboratories to choose from. Selecting from these instruments must be made by the supervisors while keeping in mind the nature of their business and needs of the production processes. Also, the accessories that will be bought along with the dispensing instrument must be considered. This may include sample reservoir, valves, lubrication system, and metering systems.

Dispensing tips. Tips with various volume capacities are equally important during precision dispensing. This is because the instruments must be partnered with efficient tips that would not allow fluid dripping during transfer. Experts also advise the usage of tips with lot numbers in order to easily track and control dispensing tasks.

Environmental conditions. Scientists, analysts and consultants are aware that certain fluids, reagents and gases alter their physical and chemical properties at varying ambient pressure, temperature and humidity. Therefore, execution of precision dispensing activities must be done during optimal environmental conditions for the liquid or fluid of interest. Proper documentation and observation of these considerations will lessen errors during the transfer.

Precision dispensing is truly an important task in the manufacturing and scientific fields. To accomplish this, certain instruments and conditions must be observed both the by the stakeholders and the personnel.
