Microstar Benchtop Laboratory
The Microstar Mobile Laboratories are suitcase-sized and are easily set-up on a benchtop in the client’s winery or lab. They provide our technicians with the capacity to demonstrate to the actual results that can be obtained with the full-scale units, by applying the technology to a small five-litre sample of the client’s wine to be treated.
Our wine technician and the client’s winemaking team can evaluate the results of a range of treatment options and confidently decide on the best option for use at full-scale.
While providing a reliable method to prove the effectiveness of a remediation or quality enhancement strategy, these units, along with our skilled technicians can provide our clients with a powerful tool in the creation of new and innovative products.
For example, lower-alcohol products can be quickly, efficiently and cost effectively developed and demonstrated on a small scale, tested and approved, prior to committing to full-scale production.
With the use of the Microstar Mobile Laboratories and our skilled wine technicians, risk can be effectively eliminated. There is simply no other tool for quality improvement or product development that offers so much versatility and surety of result so quickly and inexpensively.
