Premium Laboratory Labware: PTFE, Glass, Plastics, Porcelain, and Condensers for Chemical Precision
Materials Properties and Core OptionsPTFE Labware
PTFE labware excels in Serious chemical resistance, handling HF, fuming nitric acid, and bases at 260°C consistently, with beakers (50-5000ml) and bottles showcasing non-stick surfaces lessening cleaning time by eighty% by way of small 0.05 friction coefficient. Virgin PTFE avoids contamination in Lab Glass Condenser trace steel 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 be certain vacuum-tight fittings devoid of grease.
Glass Labware
Glass labware utilizes borosilicate three.three for 166°C thermal shock tolerance, which includes volumetric flasks (ten-10L) accurate to ±0.05% at 20°C and Erlenmeyer flasks (twenty five-6000ml) for mixing under stirring. Obvious transparency displays reactions, minimal alkali launch satisfies pH-sensitive titrations, dry-heat sterilizable to a hundred and eighty°C. Essential for distillations and reflux, normal in College organic chemistry with ground joints (ten/eighteen to 34/35) for leak-totally free assemblies.
Glass Labware Assembly
Glass labware assembly connects through conventional taper joints with PTFE sleeves for grease-totally free seals underneath one torr vacuum, forming distillation setups like flask-condenser-receiver with 24/forty sizing for 1L volumes. Clip assemblies stop breakage, modular for Soxhlet extractors managing forty eight hours, lowering set up faults 60% in teaching environments. Pre-assembled reflux kits incorporate boiling chips, great for essential oil isolation.
Plastics Labware
Plastics labware employs PP for autoclavable racks (around 134°C, one hundred cycles) and HDPE carboys (20L) resisting eighty% HNO3, light-weight at one/5th glass excess weight for Risk-free transportation. PS petri dishes (90mm) disposable for cultures, polycarbonate cylinders effects-resistant to drops from 1m. Expense 70% decrease than glass, perfect for superior-throughput ELISA with 96-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-absolutely free, reusable five hundred+ situations publish-firing cleanup. Used in cement labs for loss-on-ignition exams, brittle character calls for padded storage.
Glass Condenser
Glass condensers element Liebig straight-tube layouts (two hundred-600mm) with 300-1200cm² cooling area for Glass Labware Assemby ethanol distillations at 100ml/hour, borosilicate jackets flowing 2L/min drinking water. 19/38 joints healthy spherical bottoms, successful for easy reflux boiling underneath a hundred and fifty°C.
Lab Glass Condenser
Lab glass condensers include things like coil Graham styles (350mm) condensing small boilers like DCM with 1800cm² space, decreasing hold-as much as 8ml for quantitative yields. Allihn bulb versions market drip return, regular for 500ml reactions yielding 98% purity.
