Spare parts that are needed are compression fittings and ferrules, plunger and injector rotor seals, an extra plunger and seals, column filters, and injector needle port seals. If you do not use pacification, you might want to keep a set of check valves on hand. I always have one coil each of 0.01- and 0.02-in tubing in addition to my column blank. A replacement solvent inlet line with a porous stone is useful in case of corrosion. If you filter solvents, you need cellulose, nylon, and Teflon filters. You also need a back-up lamp for your detector. 

A electrooptic polymer crosslinked film was formed by spin-coating a 25 wt% of the Step 12 product in cyclopentanone onto an ITO covered glass slide. The solution was filtered through a 0.2 pm nylon filter, spin-coated at 500 rpm for 6 seconds and 1000 rpm for 30 seconds, and then soft baked at 50°C overnight under vacuum to give a 3.2 pm thick film. The film was corona poled with a needle at 20 kVand heated to 220°C for 5 minutes for crosslinking. The film was then cooled to ambient temperature under the applied field to give an electro-optic film with an raa of 36 pm/V at 1.31 pm. 

According to the literature (see section S087 there) damage due to mineral acids can easily be recognized under the microscope by means of the irreversible swelling of the nylon fibres. Acid residues can also be detected microscopically by embedding the sample in 0.1% Methyl Orange solution (typical needle formation, see Section 8.5.2). 

Figure 4,17a The high-frequency [HF] capsule. When the capsule has reached the intended region, it is exposed to an HF field. This induces an increased temperature in a heating wire, which leads to melting of a nylon thread and release of a steel needle. The needle perforates a latex balloon which contains the drug solution, and the drug is released.

The spleens are disrupted with forceps or needles in lx PBS (PBS) and the cells dissociated by gentle teasing followed by filtering through a 100- and then a40-pm nylon cell strainer to remove connective tissue cells.

Because of its toughness, nylon fiber is suitable for nonwoven needle-punched floorcovering products. Nylon nonwoven fiber can be found in garment interlinings and wipes for its strength and resilience. It is also used Ni/H and Ni/Cd batteries as nonwoven separators in high performance wipes, synthetic suede, heat insulators, battery separators, and specialty papers and in automotive products, athletic wear, and conveyor belts. 

The consumption of polypropylene carpet in West Europe is about 0.5 MT, which is about 50% of all flooring materials for 2.6 billion sq.m. It is second to 3.6 billion sq.m, for nylon, whereas polyester is only used for bathroom rugs. Among the flooring materials used in West Europe, tufted carpet accounts for 60%. Among 500,000 tons of polypropylene carpet, tufted carpet accounts for 150 KT, machine woven, 130 KT, needle-punched, 100 KT, and carpet backing, 100 KT. 

Polypropylene fabric for furnishing has been produced primarily by machine weaving. The current trend is to produce furniture upholstery with polypropylene tufted fabric of medium-denier BCF, air-textured yarn, and draw-textured yarn. More than one fourth of polypropylene upholstery is produced by needle punch. Polypropylene upholstery is widely used for sofa covering. Although the air-textured yarn is most economical, it is also used in combination with the BCF yarn. About 40% of polypropylene fabric is used in furnishing, of which 14% is used in cars. Among the automotive fabrics consumed in West Europe in 2000, 41.7%) was polyester, 26.1% nylon, 13.9%i polypropylene, and 11.8% viscose. It is estimated that the consumption will increase from 259 KT in 2002 to 302.9 KT in 2006. 

For blind nuclear injections, oocytes are placed into a petri dish containing a 1.0-mm nylon mesh (Small Parts Inc., Miami Lakes, FL, cat. Q-CMN-1000). The mesh can be attached to the bottom of the dish with a few drops of chloroform. The grid wells of the mesh are similar in dimension to the diameter of the oocyte and serve to hold the oocytes in place. The petri dish is filled with MBSH media and the oocytes are oriented under a stereomicroscope with a pair of blunt forceps in the grid wells, with the pigmented animal hemisphere at the top. The injection needle is inserted at the center of the pigmented hemisphere and the needle tip is driven into the oocyte a depth of approximately one-fifth the diameter of the oocyte. The success rate of blind injections depends greatly on practice, but eventually a nuclear hit-rate of 70-90% is obtainable. The best way to practice nuclear injections is to inject oocytes with a 20 mg/ml solution of blue dextram and determine if the blue color is associated with the nuclear or cytoplasmic fractions after oocyte dissections. It should also be noted that RNA can be injected directly into isolated nuclei devoid of cytoplasm (Terns and Dahiberg, 1994). 

The bicomponent fibres are suitable for felts, needle-punched carpets and tiles and upholstery fabrics the appearance of these products is more pleasant than that of uncrimped fibres owing to the absence of gloss and they have a bulkier, softer handle. Continuous crimped yams could be suitable for certain types of stretch fabrics or knitted products but so far these products have not reached the commercial stage. Attempts to use the bicomponent fibres for tufted carpets have not been satisfactory so far for two reasons. One reason is that the resilience of the piles is less than that of wool or nylon. Another reason is that fibrillated fibres may show a tendency towards a further fibrillation under severe wear or abuse.

Genomic DNA was sheared by a passage through a fine syringe needle and subjected to CsCl centrifugation using conditions outlined by Rochaix (1982). Fractions were collected and absorbance at 260 nm was recorded. Ten ul of each fraction was treated with 0.5 ml 10 mM NaOH and the DNA bound to nylon membrane. These filters were hybridised to several gene probes. 

Two holes are made in the bottom of a 1.5-mL Eppendorf tube with a 19-gage needle, and the bottom is plugged with a small piece of nylon wool. The Eppendorf is then filled with 1 mL of swollen G25 Sepharose resin. 

Instead of the hard PE tube which may exert an untolerable stress on the pulsating soft carotid, the patency rate of PVA tubes which were not thermally treated and hence very soft have been studied. The obtained results are summerized in Table 6 The length and the outer and inner diameter of this tube are 1.8 cm, 0.8-0.9 mm, and 1.1-1.2 mm, respectively. Anastomosis was not carried out with the cyanoacrylate adhesive but with a suture of nylon 11-0 since the adhesive was biodegradable, leading to disconnection of the tube from the carotid. The cyanoacrylate adhesive was only used in the case where bleeding from needle holes of the PVA tube did not cease be-...
