Samples and standards are treated in an exactly identical manner as they travel the length of the fluidic pathway, eliminating the necessity of a steady state signal, however, since the presence of bubbles create an almost square wave profile, bringing the system to steady state does not significantly decrease throughput ( third generation CFA analyzers average 90 or more samples per hour) and is desirable in that steady state signals (chemical equilibrium) are more accurate and reproducible. The air bubbles also assist mixing by creating turbulent flow (bolus flow), and provide operators with a quick and easy check of the flow characteristics of the liquid. The air bubbles segment each sample into discrete packets and act as a barrier between packets to prevent cross contamination as they travel down the length of the glass tubing. An essential principle of SFA is the introduction of air bubbles. The tubing passes the samples from one apparatus to the other with each apparatus performing different functions, such as distillation, dialysis, extraction, ion exchange, heating, incubation, and subsequent recording of a signal. The continuous stream of liquid samples and reagents are combined and transported in tubing and mixing coils. In Segmented flow analysis, a continuous stream of material is divided by air bubbles into discrete segments in which chemical reactions occur.

Stepper motor ensures fast and accurate label application with only an inaccuracy of ?0.Continuous flow analysis (CFA) is a general term that encompasses both Segmented Flow Analysis (SFA) and Flow Injection Analysis (FIA).

Missing-label feature in-built to avoid unlabelled products.

Fully adjustable product sensor ensures all materials/shapes are recognised.

One-button teach label sensor makes for quick setup and product changeover.

Additionally, the conveyor and labelling heads are all automatically synchronised via the control panel to ensure perfect labelling time and time again, with minimal setup when changing between products. The PL-521 incorporates a high-quality LCD control panel featuring inbuilt trouble-shooting and training for operators to ensure minimal downtime on your production schedule. Manufactured in strict compliance with GMP standards the PL-521 is made from 304 grade stainless steel and high quality aluminium which ensures longevity even in the harshest of environments. It incorporates a single horizontally positioned labelling head and comes with an optional infeed system to reduce operator input.ĭesigned to be used as a continuous, reliable, high-speed labelling machine, it’s manoeuvrable and simple to change between production lines or to remove it for cleaning.

Used extensively by the pharmaceutical and cosmeceutical industries, this machine handles vials, test tubes, narrow containers and much more. This machine offers fully automated horizontal wrap-around labelling for all cylindrical containers regardless of shape, designed for use with those containers that refuse to stand up on a regular conveyor line or are prone to toppling. Pack Leader’s PL-521 Horizontal Wrap-Around Labeller is part of the extraordinary fleet of high-quality, versatile labelling machines on offer by Packserv.
