Humans are the biggest source of contamination in the cleanroom. This is the reason why high quality cleanroom garments are absolutely essential for protection of the product.
The following aspects should therefore be considered when choosing garments:
- technical features of the Cleanroom fabric
- wearing comfort and physiological characteristics
- garment construction, e.g. the quality of the seams, the fitting etc.
In order to have an optimal running “system of cleanroom garments” it is necessary that all the individual demands on the cleanroom garments be checked with the requirements of the user at their workstation. Only once this is done the filter between human and product can become effective.
Trust in our competence. Making a decision as to which system gives an optimal solution for your cleanroom is not always easy. For this reason we offer our extensive experience within the field. In order to provide the perfect solution for you, we have devised the following procedures to make the choice of appropriate products easier.
Amongst them are:
- Tests of fabrics under a standardised procedure
- Co-operation with independent institutes to prove our quality standards
- Assembly and continuous development of our own test cleanroom including the ability to test cleanroom products with the use of the Helmke Drum-Method or the modified ASTM F51-68 test methods
- Supply of technical data provided by the manufacturer
- Despatch of samples to our customers for in situ testing
- Complete technical back-up from our in house experts
- Links to a world-wide network of leading cleanroom product manufacturers
This grants our customers complete information for all quoted products, and a high level of confidence whenever an order is placed.
Disposable and Protective Clothing
Disposable clothing are often a necessary addition to textile cleanroom garments. Depending on the application, a variety of designs and quality have to be considered (e.g. antistatic). When using toxic or other dangerous materials disposable coveralls with seals are often required.
The practical usage of different components, possibly also with standard cleanroom garments can achieve contamination reduction. Disposable clothing can also be delivered sterile – singly or packaged as a set – on request. We would be pleased to help with any questions you might have regarding disposable clothing.
Gloves and Finger Cots
As cleanroom gloves are the only garments that commonly come into contact with the product, they have to meet particularly high requirements:
- the abrasion and particle permeability should be as low as possible
- the sense of touch should be kept as sensitive as possible
- the transmission of fingerprints due to sweat and grease must be prevented
Each product has different requirements for the type of glove used. Therefore one cannot assign a glove to all products or processes. So before choosing cleanroom gloves and finger cots, we recommend testing a selection to enable you to choose the glove for your particular requirements.
For the glove user there is often a question mark over the necessity of using disposable gloves, with their associated lower comfort level – if textile gloves would also satisfy the demands of the workplace.
Generally for usage in cleanroom conditions it is always better to choose a powder free, post cleaned glove made from Latex, Nitrile, Vinyl or other synthetic materials such as PE, Neoprene, etc. Only these skin-tight and AQL tested powder free disposable gloves guarantee the necessary protection for your products against contamination caused by human skin.
Where operations and processes require less stringent precautions within cleanrooms then textile gloves may provide the solution. Finally the user has to decide which gloves will meet his requirements.
In almost every cleanroom, special wipes are used for a variety of applications. When searching for an appropriate wipe you should define which requirements the wipes should fulfill:
- Is the wipe supposed to be for dry or for wet cleaning?
- Should the wipe be especially low in particle emission?
- Should it be a soft wipe, which does not scratch the product?
- Should the wipe be resistant against chemicals?
- Can the surface or the item to be cleaned damage the wipe?
As wipes have many different applications, we offer you a variety of cleanroom wipes made of a number of basic materials, which are produced by varying manufacturing methods. The most important base types are:
- Polyester/cellulose blend
- Micro fibre
- Polyurethane foam, etc.
- Saturated wipes mainly made of polypropylene
Within our standard product range we cover the most common requirements for cleanrooms. In addition, for special cases, we work closely with national and international wipe manufacturers with whom we develop individual customer specific solutions. Their full range is available through us.
Tacky mats prevent the unintentional importation of large quantities of particles into the cleanroom on the soles of people's shoes. The combination of a washable permanent adhesive mat and a strongly adhesive peel off tacky mat offers the optimum protection and reduces the running costs.
