Our eks ® Hi Tech Oil has been developed for us for lubrication of reusable surgical and 

dental instruments. 

For the medical science there are counting highest requirements in reference of quality, 

ingredients and toxicologically harmlessness. The medical instruments have to be lubricated 

prior to sterilization. That is why medical oil has to be vapor permeable for autoclave 

(134°C/273°F) and heat resistant over 180°C (356°F) for heat sterilization. The premise for 

placing a medical product or medical equipment on the market (like our eks ® Hi Tech Oil) is 

the validation of these products. That means an inspection of the product by an approved


laboratory which proves the conformity to the European guideline 93/42/EEC for medical 

devices to achieve the admission as medical product. We have assigned the well-respected 

laboratory SGS Institut Fresenius to verify the eks ® Hi Tech Oil that we are allowed to 

register this product as medical product according to 93/42/EEC and to achieve the 

admission for a medical product with the CE-marking. 

The most available instrument oils are not appropriate for heat sterilization. Our oil is 

approved for autoclave and heat sterilization. 

Furthermore our eks ® Hi Tech Oil is physiologically harmless, odorless, vapor permeable and 

equates the requirements of DAB and LFBG as well as USDA and FDA (H1) and is heat 

resistant up to 260°C (500°F) and leaves no encrustations/residues on the surfaces. 

With this high quality standard the eks ® Hi Tech Oil is also applicable for the lubrication of: 

• Orthodontic and dental instruments 

• Veterinary instruments 

• Laboratory instruments 

• Chiropody-/podology instruments 

• Cosmetic and manicure instruments 

• Machines in food industry (food grade lubricant) 

Our eks ® Hi Tech Oil provides an excellent corrosion and oxidation protection and is 

odorless, transparent and free of silicone. 

For an order quantity of 300 pcs. private label is also available.

A world first: We proudly present our brand new product, the eks ® 

® which is registered as medical product according to the 

European guideline 93/42/EEC, for reconditioning of reusable instruments with satin 

finished surfaces and for removal of kondensides, stains and corrosion. Our world first is that 

we combined our eks Diamond Rubbel with monocrystalline diamonds in 20-30 µm (Micron). 

The diamonds as the hardest known material is able to treat any surface. Also handy for 

gently cleaning porcelain or just about any ceramic surface. As a matter of course the eks ® 

® 

is a product Made in Germany. 

The eks ® 

® is also the perfect tool for cleaning surgical and 

dental burs, sterilization container, stainless steel tables and operating rooms. It removes 

the fine metallic residue keeping the rod in like new condition. Over time the buildup will 

make the burs super smooth and it just won't do much. This will help restore its 

abrasiveness.

Part II: Remarks on preparation 

14. General principles on hygiene and preparation 

• Brand new instruments and instrument sent back after repair should be prepared for first time usage as if they had already been used. 

The protective packaging for transport, protective caps, etc, are not suitable for sterilisation. 

• Use only authorised agents (RKI, DGHM/ VHA, FDA, etc.). 

• Alkaline and pH-neutral cleaning agents may be used. 

• CAUTION: DO NOT USE ANY ALKALINE CLEANERS >PH/ ON INSTRUMENTS CONTAINING ALUMINIUM 

• Water quality conforming to DIN EN 285 Appendix B. 

• Sterilizers conforming to DIN EN 285 or DIN EN 13060. 

• Cleaning and disinfection devices conforming to DIN EN ISO 15883 Parts 1 and 2. 

• Use only procedures sufficiently validated for the particular device and product for cleaning/disinfection/sterilization. 

• Strictly observe all manufacturer's instructions and recommendations. 

• In addition, observe all legislative provisions and hygiene regulations in force in your country. This applies in particular to the various 

rules in relation to effective deactivation of prions. 

15. Preparation at the place of use and for cleaning/disinfection 

• Remove residues from the application immediately! 

• Do not use any metal brushes or steel wool! 

• Do NOT soak in salt (NaCl) solution! 

• Never leave instruments under stress loads, leave jointed instruments in open position, 

• Disassemble dismountable instruments, subject narrow-necked instruments and parts to special pretreatment! 

• Handle and store all instruments appropriately! 

• Wet disposal: Wait max. 1 hour before preparation! 

• Dry disposal: Wait max. 3 hours before preparation! 

16. Manual cleaning and disinfection 

• Machine cleaning/disinfection is always preferable to manual cleaning! 

• Manual cleaning should only be used where no machine is available and in exceptional cases. Even in such situations, additional 

validation processes appropriate to the product and process will be required and will be the responsibility of the user. 

• Do not use any metal brushes or steel wool! 

• Clean narrow necked instruments and parts with particular care! Page 2 of 3 


17. Ultrasonic cleaning 

• Maximum temperature: 50 ° C. 

• Frequency: 35 – 45 kHz 

• Required cleaning time: 4-5 minutes 

• Insert jointed instruments in open position! 

• Fill instruments containing lumina with fluid ensuring that no trapped bubbles are present, aligning them appropriately for the ultrasonic 

effect! 

18. Machine cleaning – thermal disinfection 

• Machine cleaning/thermal disinfection is the preferable method to be used! 

• Never leave instruments under stress loads, leave jointed instruments in open position, disassemble dismountable instruments, position 

narrow-necked instruments and parts with special care and/or use specialised rinsing equipment! 


• Temperature for disinfection max. 95°C 

• A0 –Value (duration/temperature) in accordance with the rating of the product according to the RKI 2 - guideline!


19. Control and maintenance 

• Instruments must be allowed cool to room temperature! 

• Reassemble instruments to check correct functioning! 

• Joints, threads and slide faces should be treated with, e.g. eks ® sterilizable Oil after cleaning/disinfection, but before checking for correct 

functioning and sterilization. Only use other treatments (paraffin or white oil based and silicon-free agents) only if they are approved and 

validated for steam and hot-air sterilization and have been checked for bio-compatibility. 

• Pick out damaged instruments, check that they have been cleaned/disinfected properly (and repeat if necessary), and send them back to 

us. 

20. Packing 

• No special requirements. 

• Packaging conforming to DIN EN 868/ ANSI AAMI ISO 11607 may be used. 

21. Sterilization 

• Heat and steam sterilization is permitted! 

• Other sterilization procedures and the flash sterilization procedure are not permitted. 

• The fractionated vacuum procedure (with sufficient drying of product, of at least 15 min). 

Autoclave/Steam sterilization: 

• Maximum sterilization temperature 138 °C (280 °F, plus tolerance in accordance with DIN EN ISO 17665-1 (and/or DIN EN 554)/ ANSI 

AAMI ISO 11134. 

• Sterilization time (Exposure time to sterilization temperature) min. 20 min (at 121 °C (250 °F) or 5 min at 132 °C (270°F)/134 °C. 

• Steam sterilizer conforming to DIN EN 13060 or DIN EN 285 

• validated as conforming to DIN EN ISO 17665-1 (or DIN EN 554)/ ANSI AAMI ISO 11134 (valid commissioning and product-specific 

performance assessment). 

Hot-air sterilization: 

• While hot-air sterilization in accordance with AKI 1 (red brochure, section 10.2) no longer represents the latest state of science, the 

procedure is still used in specific cases: As long as a hot-air sterilizer remains in operation, the following special observations apply: 

• At temperatures above 185°C paraffin oil resinifies and thus no longer provides a lubrication function, thus reducing the functional 

performance of affected instruments. A synthetic oil such as eks ® sterilizable Oil has also been validated for hot-air sterilization and does 

not resinify at high temperatures, and thus does not take on any brown discolouration. 

• Where the intended temperature is substantially exceeded, there is a danger that of a loss of hardness and thus of functional 

performance as well as a danger of corrosion. This may cause many instruments to lose their practical functional value. In addition, 

plastics (e.g. coloured rings on instruments) may be damaged or destroyed by high temperatures. 

• In order to guarantee an even distribution of heat in the sterilization chamber and thus in the objects being sterilized, the indication on 

load volumes contained in the instructions for usage of the sterilizer's manufacturer must be strictly observed. 

• MIC instruments and endoscopes should never under any circumstance be sterilized using hot air. 

STERILIZATION IS NO SUBSTITUTE FOR CLEANLINESS 

22. Storage 

• Dry, protected from dust, protected from exterior forces, not subject to large fluctuations in temperature and not in the immediate 

vicinity of aggressive agents. 

• Appropriately on trays, in containers and cabinets. 

• There are otherwise no particular additional requirements. 

23. Confirmation – Note 

The above instructions have been judged appropriate for the preparation 

of medical instruments intended for reuse. 

It is the responsibility of the user (person in charge of preparation) to ensure the preparation actually carried out, with the equipment, material and 

personnel employed in the preparation facility achieves the required results. For this reason, validation and monitoring of the procedure's routines 

are normally necessary. 

In addition, every deviation that the user (person in charge of preparation) may make from the instructions prepared by each relevant manufacture 

should be carefully assessed for its individual effectiveness and for any possible negative effects of such deviations.
