Top quality Laboratory Labware: PTFE, Glass, Plastics, Porcelain, and Condensers for Chemical Precision
Product Properties and Core CapabilitiesPTFE Labware
PTFE labware excels in extreme chemical resistance, handling HF, fuming nitric acid, and bases at 260°C constantly, with beakers (50-5000ml) and bottles featuring non-stick surfaces decreasing cleaning time by eighty% by means of small 0.05 friction coefficient. Virgin PTFE avoids contamination in Glass Labware Assemby trace metal 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 certain vacuum-tight fittings devoid of grease.
Glass Labware
Glass labware employs borosilicate 3.3 for 166°C thermal shock tolerance, including volumetric flasks (10-10L) exact to ±0.05% at 20°C and Erlenmeyer flasks (25-6000ml) for mixing less than stirring. Very clear transparency displays reactions, reduced alkali release fits pH-delicate titrations, dry-heat sterilizable to 180°C. Important for distillations and reflux, conventional in university natural chemistry with ground joints (10/18 to 34/35) for leak-cost-free assemblies.
Glass Labware Assembly
Glass labware assembly connects by using standard taper joints with PTFE sleeves for grease-totally free seals below 1 torr vacuum, forming distillation setups like flask-condenser-receiver with 24/40 sizing for 1L volumes. Clip assemblies prevent breakage, modular for Soxhlet extractors operating forty eight several hours, cutting down set up mistakes 60% in training environments. Pre-assembled reflux kits include things like boiling chips, ideal for important oil isolation.
Plastics Labware
Plastics labware employs PP for autoclavable racks (up to 134°C, a hundred cycles) and HDPE carboys (20L) resisting 80% HNO3, light-weight at 1/fifth glass excess weight for Harmless transport. PS petri dishes (90mm) disposable for cultures, polycarbonate cylinders impact-proof against drops from 1m. Price tag 70% reduced than glass, perfect for large-throughput ELISA with ninety six-nicely plates minimizing cross-contamination.
Porcelain Labware
Porcelain labware withstands 1450°C peaks in crucibles (ten-1000ml) for muffle furnace ashings, unglazed interiors absorbing molten salts in gravimetry, density two.4g/cm³ preventing flotation. Glazed mortars (100ml) grind samples abrasion-cost-free, reusable five hundred+ situations post-firing cleanup. Used in cement labs for loss-on-ignition exams, brittle character needs padded storage.
Glass Condenser
Glass condensers attribute Liebig straight-tube models (two hundred-600mm) with 300-1200cm² cooling location for Glass Condenser ethanol distillations at 100ml/hour, borosilicate jackets flowing 2L/min h2o. 19/38 joints healthy round bottoms, effective for simple reflux boiling down below one hundred fifty°C.
Lab Glass Condenser
Lab glass condensers contain coil Graham types (350mm) condensing small boilers like DCM with 1800cm² place, minimizing hold-nearly 8ml for quantitative yields. Allihn bulb versions promote drip return, common for 500ml reactions yielding ninety eight% purity.
