What is ISO 594 1?
ISO 594/1 specifies the general requirements of conical fittings with a 6% (Luer) taper for syringes, needles and certain other medical equipment.
What is ISO 594?
ISO 594 is a testing standard that defines and measures the general requirements for 6% taper conical fittings. The requirements tested in this method include gauging, liquid and air leakage, separation force, unscrewing torque, ease of assembly, resistance to overriding, and stress cracking.
Is ISO 594 obsolete?
ISO 594 is replaced with ISO 80369-7. ISO 594 was replaced with ISO 80369-7 in 2016. The old numbers: ISO 594/1 and ISO 594/2; have been replaced with: ISO80369-7.
What is the difference between ISO 594 and ISO 80369?
Unlike ISO 594-2, the new standard adds a flexural modulus of 700 MPa or higher – any softer material cannot be used for compliance to this standard. ISO 80369-7 also states that by using modern test equipment and methods, it is now practical to define the dimensions with greater precision.
What is a luer fitting?
At its most basic level, a Luer fitting is defined as a small-bore, friction based, leak-proof connector. Its prominent use is to connect tubing and equipment for the transfer of fluids and gases.
What is a luer lock connector?
“Luer-Lock” style connectors are often generically referred to as “Luer lock”, and “Luer-slip” style connectors may be generically referred to as “slip tip”. Luer lock fittings are securely joined by means of a tabbed hub on the female fitting which screws into threads in a sleeve on the male fitting.
What is 6% luer taper?
A luer is a standardized connection type based on a conical taper design. This taper is 6% or 1.72 degrees from the centerline. This taper is often referred to as the luer taper.
What size is Luer lock?
Luer-tip and Lock needles can be connected to PTFE tubing with an outer diameter of 3 mm or 1/8 inch. 3 mm or 1/8 inch. The Luer-lock syringes can be connected to PTFE tubing with an outer diameter of 3 mm or 1/8 inch.
Why is it called Luer lock?
The ‘luer slip’ is a universally agreed taper that ensures a leak-proof connections between a syringe (the male part of the taper) and a needle (the female part). The fitting is named after a German medical instrument maker called Hermann Wülfing Luer.
What is the meaning of Luer?
: a glass syringe with a glass piston that has the apposing surfaces ground and that is used especially for hypodermic injection.
Are luer lock needles universal?
Luer Lock is an industry standard tapered termination utilized by most syringe manufacturers including medical Hypodermic syringes. Luer Lock needles are common because their design is controlled by a series of universal standards which guarantees compatibility between manufacturers.
Can you use any needle with Luer lock syringe?
Can I use any of these luer-lock needles in any of my C-R Syringes? No, you cannot.
How many ml is 3 units of insulin?
How to Convert Insulin Units to Milliliters (ml) Using U-100 Insulin

How much is 3 mL in a syringe?
The red label on this syringe equals 0.47 ml. If you pet needs a larger amount of an oral medication, you may be given a three milliliter syringe. It may be called a “3 ml” syringe or “3 cc” syringe. Each small black mark equals 0.1 ml (i.e., one-tenth of a ml).
How many mg are in a 3ml syringe?
Additionally, there also was a statistically significant difference in the average ondansetron dose compounded using a 3-mL syringe (4.03 mg) and a 10-mL syringe (4.18 mg) (P=0.027). The accuracy and reproducibility of the 2-mL desired dose volume decreased as the compounding syringe size increased from 3 mL to 10 mL.
