The film sample, pellet or optic is held in place by a magnetized rubber plate. These holders fit in the universal 2” x 3” slide mount in all spectrophotometers. Use of paper inserts facilitates mounting small samples and pressing KBr pellets. Paper inserts are used to make KBr pellets by dropping them into the bore of a 13mm die set.
Transfer all buffers and samples into vials, and place them in proper trays. Hold buffers H and D at 25 °C (tray 25 °C); on the other hand, hold the samples and quenching buffer at 0 - 2 °C (tray 0 °C). Place the samples in 150-µL glass inserts (see the Table of Materials) first, and then transfer them into vials. Preparation of the instrument
inserts have practically no dead volume. The syringe needle can strike the bottom of the insert without being damaged. The polymer feet act as a shock absorber. This allows all of the sample to be withdrawn. These inserts are self-aligning and stand straight. Conical Glass Inserts (2714S15)
Screw-top vials also come in different sizes, with vial caps made of either aluminum for crimp seals or plastic. Amber glass vials are available in 2-60 ml volume with a screw top. Inserts work in conjunction with any autosampler and fit either standard or wide openings vials.
MS®sample vials provide advantages over the standard straight glass sample vials. The flared end of the vial makes loading a liquid sample much easier since the flare helps guide the syringe needle into the vial. The flared end also makes the vial much stronger so that vials can easily be inserted and removed from the end of the probe using

Samples were then dissolved in HPLC-grade tetrahydrofuran (THF), filtered through 0.2 μm filter, and loaded into vials with a septum for GPC. Molecular weight was measured by GPC (THF, 20°C, 1.0 mL/min) against polystyrene standards on a Hewlett-Packard instrument (series HPLC) equipped with Polymer Laboratories 5 μm mixed-C columns and

Microvolume inserts are sold in both glass and polyproylene materials. Polypropylene inserts are recommended for pH-sensitive samples, greater solvent compatibility, biological samples, and ionic samples becasue of the material′s inertness.
Several styles are offered including flat bottom, concial inserts with a top spring or a bottom spring, and concial without springs.
