High quality Laboratory Labware: PTFE, Glass, Plastics, Porcelain, and Condensers for Chemical Precision
Material Attributes and Main FunctionsPTFE Labware
PTFE labware excels in Intense chemical resistance, managing HF, fuming nitric acid, and bases at 260°C constantly, with beakers (fifty-5000ml) and bottles featuring non-adhere surfaces lowering cleansing time by 80% by means of reduced 0.05 friction coefficient. Virgin PTFE avoids contamination in Glass Labware Assemby trace metallic Evaluation (<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-restricted fittings without grease.
Glass Labware
Glass labware employs borosilicate three.3 for 166°C thermal shock tolerance, which include volumetric flasks (10-10L) correct to ±0.05% at twenty°C and Erlenmeyer flasks (25-6000ml) for mixing beneath stirring. Apparent transparency monitors reactions, very low alkali launch suits pH-delicate titrations, dry-warmth sterilizable to 180°C. Essential for distillations and reflux, typical in College natural chemistry with floor joints (ten/eighteen to 34/35) for leak-free of charge assemblies.
Glass Labware Assembly
Glass labware assembly connects by means of standard taper joints with PTFE sleeves for grease-cost-free seals less than 1 torr vacuum, forming distillation setups like flask-condenser-receiver with 24/40 sizing for 1L volumes. Clip assemblies avert breakage, modular for Soxhlet extractors functioning 48 hours, minimizing set up errors 60% in educating environments. Pre-assembled reflux kits include things like boiling chips, great for important oil isolation.
Plastics Labware
Plastics labware employs PP for autoclavable racks (approximately 134°C, a hundred cycles) and HDPE carboys (20L) resisting eighty% HNO3, light-weight at 1/5th glass bodyweight for Risk-free transportation. PS petri dishes (90mm) disposable for cultures, polycarbonate cylinders impact-resistant to drops from 1m. Expense 70% decrease than glass, perfect for superior-throughput ELISA with ninety six-nicely 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-cost-free, reusable five hundred+ situations post-firing cleanup. Used in cement labs for loss-on-ignition tests, brittle nature demands padded storage.
Glass Condenser
Glass condensers characteristic Liebig straight-tube types (two hundred-600mm) with three hundred-1200cm² cooling spot for Lab Glass Condenser ethanol distillations at 100ml/hour, borosilicate jackets flowing 2L/min h2o. 19/38 joints fit spherical bottoms, efficient for easy reflux boiling below 150°C.
Lab Glass Condenser
Lab glass condensers include coil Graham kinds (350mm) condensing reduced boilers like DCM with 1800cm² region, lowering hold-as much as 8ml for quantitative yields. Allihn bulb versions promote drip return, regular for 500ml reactions yielding 98% purity.
