Cat No. Description Price Per FLM-150-050 Nichrome Wire with Loop 4.39 10pk FLM-150-100 Platinum Wire 0.25mm dia. 37.51 150mm 4 CHARCOAL BLOCK Compressed charcoal blocks, useful to help in identifying minerals and metal salts by flame testing samples in a cavity made in the block, and for oxidation & reduction experiments, often using a blowpipe to intensify the heat source. Also useful as a base when soldering (reflects the heat back into solder joint). Dimensions 100 x 25 x 25mm 2 NEEDLE/WIRE HOLDERS For holding inoculating loops and flame test wires. Length 150 mm, made from aluminium with jaw clamp to hold wire. Suitable for use with 27 to 24 swg wires or needles (0.42 to 0.56 mm diameter). On first use these needle holders require the collar tightening extremely hard to ensure a firm grip of the innoculating loops. Cat No. Description Price Per DIN-150-100 Needle Holder 2.06 ea. 5 WELDING FILTER LENS Shade 9, glass welding filter lenses, with ground edges, as recommended by CLEAPSS for viewing burning magnesium etc. Dimensions: 107 x 82mm. Supplied as a pack of 10 filters. Cat No. Description Price Per SEG-100-100 Welding Filter Lenses 8.40 10pk 6 SPECTROSCOPE - STANDARD For the rapid qualitative examination of composition of emission and absorption spectra. Comprises a plated brass pipe with adjustable slit, drawtube and multi-element prism. Supplied complete in a lined wooden case. Cat No. Description Price Per OPL-700-100 Spectroscope - Standard 45.12 ea. 7 SPECTROSCOPE - SUPERIOR A high quality diffraction grating spectroscope for the viewing of Fraunhofer lines, flame tests in chemical analysis, absorption spectra through liquids, bright line spectra from discharge tubes, etc. The spectroscope features a large diameter eyepiece aperture, to facilitate comfortable viewing of the single, large and bright spectrum which is centrally placed in the field of view. High quality optical components ensure that absorption bands show up clearly - even weak bands that are sometimes difficult to detect. The spectrum is generated by a particularly bright transmission diffraction grating of 600 lines/mm. This robust unit is of fixed construction, with no need for adjustment, and comes supplied in a protective box. Size: 105mm long x 25mm diameter. Weight: 115g. Cat No. Description Price Per OPL-750-100 Spectroscope - Superior 83.95 ea. 1 FLAME TEST GLASS Cobalt blue coated glass pieces, for safe viewing of bright flames e.g. when burning magnesium etc. Dimensions 75 x 50mm. Supplied individually. Cat No. Description Price Per FLM-100-050 Flame Test Glass 13.83 ea. approx. Cat No. Description Price Per FLM-050-100 Charcoal Block 2.10 ea.
