Background – Gram’s Staining Technique
The Gram staining method, named after Hans Christian Gram, the Danish bacteriologist who originally devised it in 1882, is one of the most important
staining techniques in microbiology. It is usually the first test performed for the presumptive identification of bacteria. The primary stain of the Gram’s method
consists of staining with crystal violet which is then fixed with iodine. The microorganisms that retain the crystal violet-iodine complex appear purple under
microscopic examination and are commonly classified as Gram positive. Others that are not stained by crystal violet, due to a decolorization, step are referred to
as Gram negative, and appear red as a result of counter-staining with safranin.
Gram staining is based on the ability of the bacteria cell wall to retain the crystal violet dye during treatment with acetone-alcohol. The cell wall for Gram positive
microorganisms have a higher peptidoglycan and lower lipid content than Gram negative bacteria. Bacteria cell walls are stained by the crystal violet. Iodine is then
added as a mordant to form the crystal violet-iodine complex so that the dye cannot be removed easily. Subsequent treatment with an acetone-alcohol decolorizer,
which is a solvent, dissolves the lipid layer from the Gram negative cells. The removal of the lipid layer enhances the leaching of the primary crystal violet stain
from the cells into the surrounding solvent. In contrast, the solvent dehydrates the thicker Gram positive cell walls, closing the pores as the cell wall shrinks during
dehydration. As a result, the diffusion of the violet-iodine complex is blocked, and the bacteria remain stained purple. The length of the decolorization step is
critical in differentiating the Gram positive bacteria from the Gram negative bacteria. A prolonged exposure to the decolorizing agent will remove all the stain
from both types of bacteria. Some Gram positive bacteria may lose the stain easily and, therefore, appear as a mixture of Gram positive and Gram negative bacteria
(Gram variable). Finally, a counter-stain of safranin is applied to the smear to give decolorized Gram negative bacteria a red or pink color.
The decolorization step is especially critical and must be timed correctly; the crystal violet stain is removed from both Gram positive and negative cells if the
decolorizing agent is left on too long. This can be particularly problematic for smears of varying thickness – thicker smears require longer exposure for proper
decolorization than thinner smears. This is the most sensitive and variable step of the procedure, and requires experience to know just how much to decolorize
manually. Many labs performing manual Gram stains have considerable quality control problems for this reason.

2.0 WORK AREA REQUIREMENTS
IMPORTANT!
The Single Slide Automated Gram Stainer unit requires a level counter top surface of a minimum of 12 inches wide by 13 inches deep with a height clearance of 16
inches. The Gram Stain Kit (Cat. No. CHB-AGS-SK) and a container filled with deionized water should be positioned at the same level as the instrument immediately
on the left side connected by the tubing coming out of the machine. Do not place reagents below the instrument.
The Single Slide Automated Gram Stainer has one tube that drains all of the waste fluids. The Single Slide Automated Gram Stainer unit drain line can be placed
down a drain or into another disposal container to accommodate the waste fluids according to your facility and local regulations.
The Single Slide Automated Gram Stainer consumes less than 400 watts of power and uses an external power supply module that is supplied with 47- 63 Hz,
100-240V, 8-4A line power. The unit requires power from a grounded outlet. The Single Slide Automated Gram Stainer overvoltage category is II, the transient
overvoltage is 1440 volts, and the pollution category is 2. The IP protection is IP20.
The Single Slide Automated Gram Stainer is installed with tubing sets to connect the instrument to the reagents. The reagent supply line is equipped with
a cannula (rigid tube) to immerse in the reagent supply container. Labels attached to those lines indicate which reagent is to be used with each line.
The line labeled as DI Water needs to be immersed in the water supply container to supply the machine with available water.
3.0 RECEIVING AND UNPACKING
Unpacking and set-up assistance for the Single Slide Automated Gram Stainer may be obtained by calling the Cardinal Health™ Technical Support Department
serviced by QuickSlide™ at [phone] (ext. 2) during the hours of 8a.m. – 5p.m, Pacific Time, Monday through Friday.
The external power supply is a Class I supply that must be connected to an earthed (grounded) main power outlet. Failure to connect the Single Slide Automated
Gram Stainer as specified will prevent the electrical safety protection features to function as designed.
The power supply is equipped with one attached power cord and one removable power cord. The attached power cord is equipped with a connector that
plugs into the Single Slide Automated Gram Stainer rear panel receptacle near the power switch. The removable power cord adapts the IEC style connector
on the power supply to the local standard AC outlet. The cord supplied by Cardinal Health™ is appropriate for the country of operation.

5.0 GRAM STAIN KITS
5.1 General Information
The Single Slide Automated Gram Stainer accomplishes automatic Gram staining by a systematically staining, rinsing, decolorizing, and counter-staining the
provided biological specimen. It is critical for the success of this automated process that the unit utilizes the Gram Stain Kit (Cat. No. CHB-AGS-SK)
from Cardinal Health™.
NOTE: For quality control purposes, Gram Stain Kits are labeled with a Kit Number, Lot Number, and Expiration Date. These values are used to track and identify the
Gram Stain Kit used in the unit, and are entered into the system as part of the Gram Stain Kit Registration procedure as explained in section 8.1.
5.2 Ordering Information
The Single Slide Automated Gram Stainer software monitors consumption of the Gram Stain Kit. When starting each Stain Cycle, the system displays a count of
the remaining number of stain cycles available in the current kit. This remaining count should be carefully monitored so that fresh reagents may be ordered and
available when needed.
5.3 Gram Stain Kit Installation
The Single Slide Automated Gram Stainer reagents are supplied to the unit through tubes connected to the individual reagent containers. Each tube is clearly
labeled with a color coded tag, and the tube cannula must be inserted into the correct reagent container. Tubes are also provided for connection to a deionized

6.0 OPERATION INSTRUCTIONS
6.1 Instrument Anatomy
The basic anatomy of the Single Slide Automated Gram Stainer consists of four parts as described below:
Display screen – the screen that prompts which buttons to select for procedure steps.
Key Pad – the twelve button key pad used to select process options on the instrument.
Cuvette – holds the slide during the staining process.
Front panel – covers the reagent supply pumps and waste drain pumps.
6.2 Specimen Slide Preparation
6.2.1 If the culture is to be taken from a Petri dish or a slant culture tube, first add a drop or a few loops full of water on the slide and aseptically transfer a
minute amount of a colony on the Petri dish. Transfer a drop of the suspended culture to be examined on a slide with an inoculation loop. Note that only a
very small amount of culture is needed; a visual detection of the culture on an inoculation loop already indicates that too much is taken. If staining a clinical
specimen, smear a very thin layer onto the slide, using a wooden stick. Do not use a cotton swab as the cotton fibers may appear as artifacts. The smear should
be thin enough to dry completely within a few seconds. The stains will not penetrate thickly applied specimens, making interpretation very difficult.
6.2.2 Spread the culture with an inoculation loop to an even thin film over a circle of 1.5 cm in diameter, approximately the size of a dime.
Position the smear at least 3/4” below the frosted area. Labels should not extend below the frosted area.
6.2.3 Fixing the specimen causes the cells to adhere to the glass slide to make possible the subsequent rinsing of the smear with water without a significant loss
of cells. This can be accomplished by methanol fixation. For best results, it is required that the methanol method be used, rather than heat, since it
is superior in preventing lysis, distortion, or damage to the cells in clinical material. Red and white cells will not be harmed, whereas heat will distort
or disrupt the cells. Passing the slide over a flame is also not recommended.
Methanol fixed slides have been shown to retain two to ten times as many cells than with heat fixation.(1) In addition, Gram positive bacteria are much less
likely to become over-decolorized when fixed with methanol rather than heat.(2)
Methanol Fixation Procedure: Air-dry the specimen. If a heat block must be used, do not set the temperature above 40°C, and do not leave the slides on the
block for over an hour. It is extremely important that the specimen does not get damaged by excessive heat. Once fully dried, fix by submerging the slide into a
Coplin jar filled with methanol. Please ensure that the methanol covers the whole smear. Drain off remaining methanol without rinsing by tapping the bottom
edge of the slide to paper towel and allow slide to air dry. Do not apply heat after the methanol dries.
NOTE: Because the slide preparation technique can vary from institution to institution and technique is not always controllable (i.e., differences in smear
thickness, fixation techniques, drying time, specimen adherence to different types and brands of slides, etc.) rare instances of carryover from slide to slide have
been reported. The chance of this can be minimized by carefully following the instructions in this manual.
NOTE: For best results with this instrument use glass slides that are positively charged such as Cardinal Health™ Microscope Slide Charged Adhesion Frosted
25mm x 75mm 1mm (Cat. No. M6143) to increase specimen adhesion to the glass slide. The adhesion of the specimen can be variable, depending on the
specimen type, volume and its thickness. Lack of adhesion is most notable in blood or bloody culture smears, so it is mandatory to use chemically treated slides
that produce a positive electrical charge in order to enhance the specimen’s attachment to the slide. Excessively thick smears can lead to a sloughing off of cells
from the slide. So it is important to prepare smears that are relatively thin with some transparency. Software and fluid flow design have been engineered to
minimize the occurrence, but rare occasions of carryover may still be possible depending on the differences in the user’s slide and slide preparation techniques.
It is recommended to reconfirm the presence of low numbers of bacteria in traditionally sterile specimens (such as spinal or joint fluid) with manual staining and
culture results.

6.4.7 Press any key on the key pad, except [ *], to commence the Automated Gram staining. The unit may now be left unattended as the slide is stained.
When the final rinse step has finished, the machine will make an audible alert to notify the operator that the stain is complete and the slide can be removed.
NOTE: Pressing the [ *] key will abort the Gram stain process and return immediately to the Run Menu.
7.0 QUALITY CONTROL
7.1 Quality Control Checks
The quality and validity of the Gram stain process of the Single Slide Automated Gram Stainer may be periodically verified by staining a slide prepared with any
known sample material. This slide may be stained using exactly the same procedures used for any specimen slide. The processed specimen slide may then be
viewed to confirm proper Gram stain technique and results. Quality Control slides may be purchased from Cardinal Health™ under catalog number CHB-GS-QC.
7.2 Self Calibration Errors
The Single Slide Automated Gram Stainer employs a “self-calibration” test during every staining cycle to verify proper system operation. This test confirms that the
optical sensor response is within a valid specified range. Out-of-Range measurements automatically cause interruption of a staining cycle and operator notification
of the error condition. After problem resolution, staining operations will resume from the point of interruption. This self-check provides additional assurance of
accurate system performance.

9.4 Cuvette Swabbing
The cuvette may build up stain residue over time. To clean it, use a foam cleaning swab (Cat. No. CHB-GS-CS) soaked in alcohol to scrub the walls of the cuvettes.
This should be done while the instrument is not in Run Mode, but while a Scrub Cycle is in process. Scrub the cuvette walls with a clean foam swab while
decolorizer and water is rinsing the chamber. Note: Be careful not to accidentally overflow the cuvette with the submerged swab when performing the wash cycle.
9.5 Deionized Water Disinfectant
In order to prevent contamination, the deionized water must have stabilized gram’s iodine disinfectant (Cat. No. CHB-GS-DI) added to the container following this
schedule, whichever comes first:
1. Every time the water container is refilled with deionized water.
2. Every 20 days of operation.
This is completed by adding 10 drops of disinfectant per gallon of deionized water into the water container.
9.6 Refilling the Water Supply
The water can be refilled at any time before the staining process has begun if the water supply is getting low.
NOTE: The new water supply must be disinfected using iodine before continuing use, refer to section 9.5 above.
To refill the water supply, do the following:
9.6.1 Remove the water cannula from the water container and place it onto a fresh paper towel or alcohol swab.
9.6.2 Fill the water container with fresh deionized water and mix in the drops of Gram’s Iodine.
9.6.3 Sanitize the water cannula using an alcohol swab and place it back into the water container and screw the lid on tightly.
Note: When removing the water cannula, if a column of air is sucked into the cannula, an error message can occur. In order to avoid possible sensor errors caused
by air entering into the water cannula, replace the water in the water container before staining a slide.
Note: If a separate sterile water container is available, it can be used to pour more deionized water into the original water container without removing the cannula.
Be sure to add the drops of Gram’s Iodine into the separate sterile water container full of deionized water, before pouring it into the original water container.
9.7 Maintenance Summary
Frequency Maintenance Procedures
Every time the deionized water is refilled (or every 20 days) • Supplement the fresh deionized water with drops of

10.0 IDLE DELAYS
The Single Slide Automated Gram Stainer contains an internal clock that is used to monitor system operations and start a timer to manage the instruments “sleep”
time to conserve energy. The software monitors the idle time by observing the elapsed time since the last key on the key pad was pressed. To set a sleep time
that works best for your lab, refer to Section 10.1 below. When the machine enters into Sleep Mode the LCD display will turn off and the pump motors will be
de-energized.
To exit the Sleep Mode press any key twice on the key pad. This will illuminate the LCD screen and display the Main Menu within 10 minutes as the pump motors
are re-energized and the operating system is activated.
The Stir operation helps maintain the integrity of the machines cuvette. While the machine is in Sleep Mode or while it is idling, the stir function rotates the pump
motors and processes a small amount of decolorizing reagent into and out of the cuvette.
The Auto-Prime feature includes a purge of all reagents, followed by a complete prime of the reagent lines. This prevents reagent evaporation in the supply lines
and maintains the unit in a ready state without wasting reagents, as each of the reagents is expelled back into the respective reagent container.
