Staining machines for the injection process
Automatic staining machines for the injection process offer enormous advantages: they reliably prevent cross-contamination and carryover, and do so with reliable, uniform staining results. Dagatron’s innovative, fully automatic staining machines all operate according to the injection process. Among other things, the staining machines are ideally suited for staining methods according to Gram, Ziehl-Neelsen, Kinyoun, staining in hematology or for fluorescence staining.
The injection process
Common to all innovative, fully automatic staining devices from Dagatron is the injection method. The injection method reliably prevents sample carry-over and cross-contamination due to the horizontal, individually stored arrangement of the preparations in the device.
The consistent, uniform staining result for the complete preparation is achieved by evenly applying the staining solution in the required reagent quantity through the injection heads by means of microprocessor control. In contrast to staining based on the spray method, standardized, repeatable results can be achieved without loss of sample material due to insufficient wetting with the staining solution.
By using a separate injector head for each reagent, the contamination of different reagents can also be excluded.
The AT series from Dagatron
Single Stainer – Single staining devices for the following staining methods
Multi Stainer – Combination staining devices for the following staining methods
INDIVIDUAL Stainer – Combination stainer as desired
The patented heating system
The WHO-compliant staining for acid-resistant bacteria (Acid fast bacilli, AFB, Mycobacteria) for preparations from body fluids, culture materials or exudates can be performed with the single stainer AT-2000K AFB Auto Stainer and the combination stainer AT-3001 AFB Multi Stainer as cold staining according to Kinyoun.
Due to the patented, innovative heating system, the single stainer AT-2000Z AFB Auto Stainer and the combined TB stainer warm according to Ziehl-Neelsen and fluorescent staining AT-3001 AFB Multi Stainer or TB warm staining according to Ziehl-Neelsen and Gram staining AT-3002 GRAM/AFB Dual Stainer even automated hot staining according to Ziehl-Neelsen at approx. 55 °C is possible. To switch between warm and cold staining methods in the same unit, the supplementary preparation carousel is inserted or removed as required.
The AFB staining with fluorescent dyes can be performed with the single stainer AT-2000F AFB as well as the combination machines AT-3001 AFB Multi Stainer and AT-3003 GRAM/AFB Dual Stainer.
The corresponding staining solutions
Of course, corresponding staining solutions which are optimally matched to Dagatron instruments are also available for specific instruments.
For the Gram stainer AT-2000G suitable for Gram staining of bacteria from human samples or cell culture and the slide stainer AT-3002/3 with multiple staining function, optimum results can be achieved with the Gram staining kit with 4 corresponding solutions.
Also for TB staining warm according to Ziehl-Neelsen as well as fluorescence staining for identification of acid-resistant bacteria, staining sets with 3 staining solutions each, optimally adapted to the TB staining machines, are available.
The stains for haematology
The hematological stainer AT-2000H, which has been specially adapted for blood testing is optimally suited for use in the hematological laboratory.
This staining device is suitable to perform the May Grünwald Giemsa (MGG) or Pappenheim staining of blood smears in a standardized, fast and economical way with constant staining quality for counting leukocytes (WBC) and erythrocytes (RBC) and for assessing the morphology of leukocytes, erythrocytes and thrombocytes (blood platelets). The BIOMED Hemafix®Staining Solutions is ideally suited for this purpose.
The self-cleaning system
After successful staining, the self-cleaning program of the staining devices can be used. The staining tables for each preparation are rinsed and centrifuged to remove liquids.
Due to the size of the injection heads with a nozzles opening of 2.0 mm, the frequent clogging of the injection nozzle by staining solutions, which occurs during the spraying process, can be excluded. The injection nozzles are designed and mounted in such a way that they are easily accessible for cleaning and can be easily cleaned together with the pump and valve.
The warning system for insufficient residual reagent volume
The function for monitoring the reagent level ensures that irregular or incorrect staining of the preparations due to insufficient residual reagent volume is avoided.
If the reagent level is too low, a warning signal sounds and staining cannot be started by mistake.
