Introduction According to Chambers Dictionary , a syringe is A medical instrument for injecting or drawing off liquid, consisting of a hollow cylinder with a plunger inside and a thin hollow needle attached; or A similar device used in gardening, cooking, etc. Syringes Syringes are available in several different designs and varieties. Syringes are available in many sizes, with volumes ranging from 0.5 ml to 60 ml. Graduation marks on the syringes represent different increments depending on the size of the syringe. There are 5 basic types of syringe tips. To maximize the measuring accuracy, the smallest syringe that can hold the desired amount of volume should be used; however, it should not be drawn up to the maximum capacity because the plunger could easily dislodge. Needles Similarly, needles are available in many sizes, which are described by gauge and length. The gauge of the needle corresponds to the diameter of its bore. The smallest needles have a gauge of 27, and the largest n...

Introduction Aseptic technique is a skill in the compounding of sterile preparations that is independent of equipment [e.g. primary engineering control (PEC) and secondary engineering controls (i.e. cleanroom) ] and environment. Proper use of Laminar Airflow Workbench (LAFW) An LAFW should operate continuously when in use. Before use, all interior working surfaces of the LAFW must be cleaned from the cleanest part of the LAFW to dirtiest part with sterile 70% isopropyl alcohol (IPA) or another disinfecting agent and a clean, nonshedding, lint-free wipe. The LAFW should be cleaned and disinfected frequently, including at the beginning of the wok shift, before the start of each batch, every 30 minutes during continuous compounding periods, when there are spills, and when there is known or suspected contamination from a lapse in the aseptic technique process. Nothing should touch the HEPA filter. Nothing should disrupt or block the unidirectional airflow between the high-efficiency pa...
