Bacterial Enumeration
The Don Whitley Scientific spiral plater eliminates the need for serial dilutions and plates out your samples so that bacterial enumeration is easy, consistent and effective. A wide range of deposition profiles is available. Bacterial Enumeration applications include dental research, food microbiology, calculating antimicrobial concentration (MICs) or studying the microbiome.

Don Whitley Scientific and Mason Technology
Mason Technology is the exclusive distributor of Don Whitley Scientific (DWS) products in Ireland. Established in 1976, DWS designs and manufactures specialist laboratory equipment for a wide range of microbiology and cell culture applications. Whitley workstations allow the precise control of levels of oxygen, carbon dioxide, hydrogen, temperature, and humidity as appropriate to the individual research application.
Mason Technology can supply, install, and commission any solution from the complete range of Don Whitley Scientific products including anaerobic workstations, GMP compliant workstations, hypoxic workstations, spiral platers, and jar and gassing systems. Our sales and service teams have been factory trained at the Don Whitley Scientific Headquarters in West Yorkshire, UK guaranteeing exceptional support for your installation, training, application, and validation/service needs.
We recognised the importance of Quality Assurance to our customers and we have held continuous certification to ISO standards since 1994. We are committed to continuous improvement, and this is backed up by our investment in an Integrated Management System (IMS). This meets, at a minimum, the requirements of the International Standards ISO 9001, ISO 14001, ISO 45001, and ISO 17025 (INAB).

More About Whitley WASP Touch®
Whitley WASP Touch® 
The Don Whitley Scientific WASP Touch ® is a precision laboratory instrument designed to deposit accurate volumes of liquid sample in an Archimedes spiral onto the surface of a rotating agar plate. Spiral plating is well documented and validated as an effective method for the enumeration of microorganisms.
Designed for the needs of modern microbiology laboratories, the WASP Touch® is a fundamentally different spiral plater with no need for a separate vacuum source. With touchscreen operation the system is extremely simple to use and provides real cost savings and process improvements.
Whether you are working in the field of dental research, food microbiology, calculating antimicrobial concentration (MICs) or studying the microbiome, this robust, reliable device could really save time and money in your laboratory.
WASP Touch® provides Automated Intelligent Monitoring Software (AIMS) to guide you through set-up and daily check routines – ensures consistent trouble-free plating. Precise quantities of sanitising fluids are dispensed automatically to maintain optimum levels. This ensures effective and efficient sanitisation takes place.
The deposition profiles possible with WASP Touch® allow bacterial and fungal colonies to be enumerated over a 100,000-fold (5 log10) range, from a minimum of 20 cfu/ml in 1000 μl pour plate mode to a maximum of 2 x 106 cfu/ml in 10 μl logarithmic mode. An optional Extended Volume Package is available, however, to allow for a greater number of replicates plates, linear deposition profile and a wider range of deposition profiles.
Spiral plating techniques are recognised in ISO 4833-2 & 7218 as well as the AOAC 977.27 standard.
Optional fully comprehensive maintenance and breakdown contracts are available to prolong the life of your investment. (Note: different arrangements apply in different countries).
WASP Touch ® Features:
- Patented automatic sanitising system automatically maintains correct liquid levels in sanitising solutions.
- Illuminated, covered working area.
- Easy serviceability.
- The sample may be aspirated from beakers, bottles and tubes – providing maximum flexibility in use.
- Automatically log date, time, deposition, user name, and number of plates produced – a powerful diagnostic tool.
- Flowsense – detects the movement of liquid through the WASP Touch®.
- Sanitising system reservoirs are available in two sizes and can contain sufficient fluid for hundreds of wash cycles – perfect for busy laboratories.
- Fully integrated vacuum waste system – occupies the smallest amount of bench width.
- Side connectors for ease of access.

More About Vacuum Source 602
Vacuum Source 602
The Whitley Vacuum Source 602 (VS602) is an electronic laboratory vacuum pump. It was specifically designed for use with the Don Whitley Scietific Automated Spiral Plater and enables liquids to be suctioned away prior to a new sample being taken for the next plating.
- Automatic electronic vacuum control, programmable from 0 to -20”Hg
- Coloured high intensity LED display
- Built-in liquid sensor that prevents operation when the reservoir is full
- 3 x 1 litre chemically-resistant, durable, polypropylene, injection-moulded flasks are supplied with each unit
- Universal voltage.
- Simple Operation
The Whitley Vacuum Source 602 is ideal for use with spiral players. It enables waste liquids to be suctioned away prior to a new sample being taken for the next plating. It also acts as a dispensing system to sanitise between samples by the vacuum-suction of Hypochlorite and distilled water. It has been specifically designed as an accessory for the Don Whitley Scientific spiral plater (the WASP Touch®).
Acting as a miniature vacuum cleaner, the Vacuum Source prevents sample contamination and contributes to the efficacy of your results. It offers flexibility and performance to suit a range of laboratory applications and is robust and simple to operate, incorporating advanced technical features for improved control.
