The oblique light (which cannot glare into the eyes of the observer) illuminates the colonies so that they appear as brilliant spots or points on a subdued background. This principle increases the contrast between the colonies and the culture medium. It improves the visibility so that very small colonies can be seen. As a result the observer works efficiently and obtains accurate data quickly.
The 4¼ inch lens has the standard 1.5x magnification and is mounted on a sliding rod for focusing to suit any operator. The glass plate has the popular wolff-nuggle ruling. On the top of the case there is a circular opening which can accommodate Petri dishes of up to 100mm external dia. The Petri dish rests directly on the counting plate. The cover is removable so that the tube can be replaced or the plate removed for cleaning.
The front surface is inclined at an angle found comfortable for most technicians. The instrument is styled to confirm with the modern laboratory style and finished in silver ash.
Resistible electromagnetic counter provides instant, cumulative and accurate recording of colony counts, phase and bacterial genetics. The counter is energised by a switch in the pen. This micro current is then amplified through a solidstate circuit to operate the electromagnetic counter. It needs no warm-up, permits counting speeds of up to 12 counts per second without sputtering and eliminate drudgery and the change of error.
This marking pen necessary for the counter permits accurate counting of growths in colonies in closed petri dishes. It is especially valuable when working the pathogens or when a contamination free culture is desired.
The marking pen is replaceable and is commercially available. The ink used in the pens also available in variety of colours in the market if different markings are desired.
The marking pen also be used in conjunction with the disposable membranes. The wet membranes could be fixed at the back of the petri dish for counting. After counting, the sheets can be indexed, dried and stored for reference.
