High quality Laboratory Labware: PTFE, Glass, Plastics, Porcelain, and Condensers for Chemical Precision
Substance Homes and Core AttributesPTFE Labware
PTFE labware excels in Intense chemical resistance, managing HF, fuming nitric acid, and bases at 260°C repeatedly, with beakers (50-5000ml) and bottles showcasing non-stick surfaces decreasing cleansing time by 80% by using lower 0.05 friction coefficient. Virgin PTFE avoids contamination in Glass Condenser trace steel analysis (<0.1ppb leaching), autoclavable at 121°C indefinitely, opaque white aiding visibility in fluoropolymer reactions. Perfect for Pakistani analytical labs processing corrosives, machined tolerances ±0.02mm make sure vacuum-limited fittings without having grease.
Glass Labware
Glass labware uses borosilicate three.three for 166°C thermal shock tolerance, like volumetric flasks (10-10L) precise to ±0.05% at twenty°C and Erlenmeyer flasks (25-6000ml) for mixing less than stirring. Very clear transparency displays reactions, minimal alkali release fits pH-delicate titrations, dry-heat sterilizable to 180°C. Important for distillations and reflux, standard in university organic and natural chemistry with floor joints (10/18 to 34/35) for leak-absolutely free assemblies.
Glass Labware Assembly
Glass labware assembly connects via normal taper joints with PTFE sleeves for grease-absolutely free seals under 1 torr vacuum, forming distillation setups like flask-condenser-receiver with 24/forty sizing for 1L volumes. Clip assemblies reduce breakage, modular for Soxhlet extractors operating 48 hrs, lessening setup mistakes sixty% in instructing environments. Pre-assembled reflux kits include boiling chips, perfect for vital oil isolation.
Plastics Labware
Plastics labware employs PP for autoclavable racks (nearly 134°C, 100 cycles) and HDPE carboys (20L) resisting 80% HNO3, lightweight at 1/5th glass fat for Harmless transport. PS petri dishes (90mm) disposable for cultures, polycarbonate cylinders influence-proof against drops from 1m. Value 70% lessen than glass, perfect for high-throughput ELISA with 96-effectively plates minimizing cross-contamination.
Porcelain Labware
Porcelain labware withstands 1450°C peaks in crucibles (10-1000ml) for muffle furnace ashings, unglazed interiors absorbing molten salts in gravimetry, density 2.4g/cm³ avoiding flotation. Glazed mortars (100ml) grind samples abrasion-absolutely free, reusable five hundred+ situations post-firing cleanup. Used in cement labs for loss-on-ignition exams, brittle nature needs padded storage.
Glass Condenser
Glass condensers attribute Liebig straight-tube models (two hundred-600mm) with three hundred-1200cm² cooling place for PTFE Labware ethanol distillations at 100ml/hour, borosilicate jackets flowing 2L/min water. 19/38 joints match round bottoms, effective for simple reflux boiling beneath 150°C.
Lab Glass Condenser
Lab glass condensers contain coil Graham varieties (350mm) condensing minimal boilers like DCM with 1800cm² spot, minimizing maintain-approximately 8ml for quantitative yields. Allihn bulb versions advertise drip return, common for 500ml reactions yielding 98% purity.
