Jun 14, 2018 · Penetration Test. The penetration test is the measures of the depth to which a needle with a definite top load penetrates the wax sample. Where the conditions of test are not specifically mentioned, the load, time, and temperature are understood to be 100 g, 5 sec, 25° respectively, and the units of penetration to indicate tenths of a millimeter.
A simple method to determine the consistency of different products is by means of a penetrometer. A typical example of consistency determination is the penetration measurement of grease. A cone assembly of given weight (150 g) is allowed to sink into a grease sample for five seconds at a standard temperature of 25 °C (77 °F).
body contains a septum and reservoir, which is made of plastic, titanium, polysulfone, or a combination. 4 A slim tube or catheter is connected to the reservoir, which is covered by a disc 2 to 3 cm in width ( Figs. 84-1 and 84-2 ). Provided a noncoring needle is used to access the septum, the septum is capable of resealing when deac-cessed.
May 1, 2010 · A specimen of normal consistency fresh cement paste is prepared and placed in a 40 mm high container. The test consists in the measurement of the penetration depth of the needle which falls down under gravity. Initial setting time is considered in this paper as the time when the needle penetration is 39 mm ± 0.5 mm.
When the needle is inserted in the refill septum (i.e., into the induction coil of the needle penetration detector surrounding the refill septum) and the AC power is applied to the induction coil of the needle penetration detector the inductance in the induction coil may be a high inductance value as indicated by inductance measurement region 58.
Supplier: Cadence Science. The deflected needle features point positioning on the axis of the needle lumen. This improved point geometry provides easier penetration and minimizes coring and tracking (particularly with finer gauge needles) Ordering information: Non-sterile. Packaged 12 needles per box.

A septum that can be penetrated cleanly and easily by a syringe needle has a longer life. Moreover, consistent injections made through such a septum help ensure accurate results.

the mechanical valve. Although some split-septum de-vices will accept a needle, a needle should never be used in a needleless system. Internal characteristics. Although their exterior . appearance may be similar, needleless connectors have internal differences that affect the way they function. Simple versus complex. The majority of needleless
Bent needles • using the wrong size needle or insert • insert has burrs Plugged needles due to septum coring Lost peak shape • examine inlet end of column with a magnifier and flashlight, looking for discoloration or particles Injection volume too large
Long injection life, pre-pierced for minimal coring. Maximum temperature 400°C. Long injection life septum typically achieves 400 injections without failure, when used with a rounded-tip (Aijiren-style) needle and autosampler or needle guide. Ideal for standard manual-injection GC and GC/MS. 3 mm. Compare this item.
Some operators choose to stain the septum with contrast; however, the effect of this on future pressure measurements should also be considered as mentioned above. Following confirmation of needle tip location, with the right hand steadying the needle, the dilator and sheath assembly is advanced smoothly over the needle.
