High quality Laboratory Labware: PTFE, Glass, Plastics, Porcelain, and Condensers for Chemical Precision
Material Houses and Main CharacteristicsPTFE 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-adhere surfaces lessening cleansing time by 80% through lower 0.05 friction coefficient. Virgin PTFE avoids contamination in Glass Labware Assemby trace metal Assessment (<0.1ppb leaching), autoclavable at 121°C indefinitely, opaque white aiding visibility in fluoropolymer reactions. Ideal for Pakistani analytical labs processing corrosives, machined tolerances ±0.02mm make sure vacuum-limited fittings without having grease.
Glass Labware
Glass labware utilizes borosilicate three.three for 166°C thermal shock tolerance, such as volumetric flasks (10-10L) precise to ±0.05% at twenty°C and Erlenmeyer flasks (twenty five-6000ml) for mixing under stirring. Very clear transparency screens reactions, lower alkali launch fits pH-sensitive titrations, dry-heat sterilizable to 180°C. Essential for distillations and reflux, regular in university organic chemistry with floor joints (10/18 to 34/35) for leak-totally free assemblies.
Glass Labware Assembly
Glass labware assembly connects via standard taper joints with PTFE sleeves for grease-no cost seals underneath 1 torr vacuum, forming distillation setups like flask-condenser-receiver with 24/forty sizing for 1L volumes. Clip assemblies avoid breakage, modular for Soxhlet extractors running forty eight several hours, cutting down setup problems sixty% in teaching environments. Pre-assembled reflux kits include things like boiling chips, perfect for vital oil isolation.
Plastics Labware
Plastics labware employs PP for autoclavable racks (up to 134°C, 100 cycles) and HDPE carboys (20L) resisting 80% HNO3, lightweight at 1/5th glass bodyweight for Harmless transportation. PS petri dishes (90mm) disposable for cultures, polycarbonate cylinders impact-resistant to drops from 1m. Price 70% reduce than glass, ideal for higher-throughput ELISA with ninety six-perfectly plates reducing 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 blocking flotation. Glazed mortars (100ml) grind samples abrasion-absolutely free, reusable 500+ times write-up-firing cleanup. Utilized in cement labs for decline-on-ignition exams, brittle mother nature needs padded storage.
Glass Condenser
Glass condensers feature Liebig straight-tube types (two hundred-600mm) with 300-1200cm² cooling spot for Plastics Labware ethanol distillations at 100ml/hour, borosilicate jackets flowing 2L/min h2o. 19/38 joints match round bottoms, productive for easy reflux boiling underneath a hundred and fifty°C.
Lab Glass Condenser
Lab glass condensers include coil Graham kinds (350mm) condensing minimal boilers like DCM with 1800cm² location, minimizing maintain-approximately 8ml for quantitative yields. Allihn bulb versions market drip return, regular for 500ml reactions yielding ninety eight% purity.
