IMPORTANT INFORMATION ABOUT GLOVES & FINGER COTS General Information 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. Powder free = cleanroom compatible? The term "powder free" has historically been poorly defined across our industry. There are only vague recommendations available and manufacturers have been able to use the term "powder free" on the packing without adherence to any minimum standards. But the manufacturers of disposable gloves make various efforts during the manufacturing and also during the cleaning process and packing in order to guarantee a certain "purity". Area of application for disposable or reusable gloves 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. We would be pleased to help you to make your choice and to put some test samples at your disposal. For our range of disposable gloves we work closely with international leading manufacturers such as for example Ansell, Kimberly & Clark, Mapa, Nitritex and Shield Scientific.

POWDER FREE LATEX GLOVES table of cleanroom classes see chapter 7.12 Latex gloves normally fit closely and offer an extremely good sense of touch. They are very flexible and therefore also tear resistant. For aseptic areas some items are offered in a sterile version, in pairs and hand specific (= left/right). For cleanroom applications a minimum length of 11"– 12" should be used, because the gloves then cover the knitted cuffs of the cleanroom garments. It is also important to have plastic packaging suitable for cleanrooms – in particular for the sterile versions. Using a paper packing for gloves,...

POWDER FREE NITRIL GLOVES GLOVES & FINGER COTS 7.3 7.3 table of cleanroom classes see chapter 7.12 This alternative is becoming increasingly commonplace because Nitrile gloves have many advantages. They offer the fit and therefore also the sense of touch of Latex gloves, they are conductive and do not hold the danger of a possible Latex allergy. In comparison with Latex and Vinyl gloves, Nitrile gloves are considered to be the most "clean" or "pure" gloves. Nitrile gloves should also have an appropriate minimum length. They are also available in sterile form packed in PE bags suitable for cleanrooms....

GLOVES & FINGER COTS 7.4 7.4 POWDER FREE VINYL GLOVES Co-Polymer gloves Vinyl do not have such a tight fit as Latex or Nitrile gloves. In contrast to the Latex gloves some of the Vinyl gloves are conductive. They should also have a minimum length of 11" – 12" and be packed in PE-bags suitable for cleanrooms. Vinyl gloves are much cheaper than Latex or Nitrile gloves, but generally not as pure. Some publications have already hinted at possible health risks. table of cleanroom classes see chapter 7.12 Article Conductive Sizes PU Art.-No. Co-Polymer Vinyl glove powder free, 12”, ambidextrous yes...

GLOVES FOR SPECIAL USAGE All materials to be used in a cleanroom have to be designed such that the products enjoy highest possible protection. Contamination, for example caused by personnel, has to be avoided by the usage of appropriate appliances. However, there are always applications where the safety of the human has to be guaranteed as much as that of the products. Beside the parameter of using cleanroom suitable gloves, one of course has to also look out that the chosen model has characteristics which give the user confidence of not being in any danger of contamination himself. When using...

GLOVES PACKED IN BOXES In the less sensitive area outside the cleanroom, the use of gloves packed in a box (light carton) becomes a possibility – and has the advantage of reduced costs. In general these gloves are shorter than the gloves suitable for cleanrooms and for health reasons also powder free. We offer Latex as well as Nitril versions. table of cleanroom classes see chapter 7.12 1 1 box packed gloves Kimtech Science Purple Xtra Article Manufacturer Sizes PU Latex glove, Kimtech Science Satinplus 9”, powder free, ambidextrous smooth surface Kimberly & Clark XS, S, M, L, XL 1000 pieces...
