Premium Laboratory Labware: PTFE, Glass, Plastics, Porcelain, and Condensers for Chemical Precision
Substance Houses and Core CharacteristicsPTFE Labware
PTFE labware excels in Severe chemical resistance, handling HF, fuming nitric acid, and bases at 260°C consistently, with beakers (50-5000ml) and bottles showcasing non-adhere surfaces lowering cleansing time by 80% via very low 0.05 friction coefficient. Virgin PTFE avoids contamination in PTFE Labware 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 certain vacuum-limited fittings with no grease.
Glass Labware
Glass labware utilizes borosilicate three.3 for 166°C thermal shock tolerance, like volumetric flasks (10-10L) precise to ±0.05% at 20°C and Erlenmeyer flasks (twenty five-6000ml) for mixing under stirring. Very clear transparency displays reactions, reduced alkali launch satisfies pH-sensitive titrations, dry-heat sterilizable to one hundred eighty°C. Important for distillations and reflux, normal in College natural and organic chemistry with ground joints (10/eighteen to 34/35) for leak-free assemblies.
Glass Labware Assembly
Glass labware assembly connects through conventional taper joints with PTFE sleeves for grease-totally free seals beneath 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 setup glitches sixty% in teaching environments. Pre-assembled reflux kits contain boiling chips, ideal for critical oil isolation.
Plastics Labware
Plastics labware employs PP for autoclavable racks (as much as 134°C, one hundred cycles) and HDPE carboys (20L) resisting eighty% HNO3, light-weight at one/fifth glass weight for Protected transport. PS petri dishes (90mm) disposable for cultures, polycarbonate cylinders impression-immune to drops from 1m. Cost 70% reduced than glass, ideal for substantial-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 stopping flotation. Glazed mortars (100ml) grind samples abrasion-free of charge, reusable 500+ moments article-firing cleanup. Employed in cement labs for decline-on-ignition checks, brittle nature demands padded storage.
Glass Condenser
Glass condensers function Liebig straight-tube patterns (200-600mm) with 300-1200cm² cooling location for Porcelain Labware ethanol distillations at 100ml/hour, borosilicate jackets flowing 2L/min h2o. 19/38 joints in good shape spherical bottoms, economical for easy reflux boiling down below a hundred and fifty°C.
Lab Glass Condenser
Lab glass condensers involve coil Graham types (350mm) condensing low boilers like DCM with 1800cm² area, decreasing hold-as much as 8ml for quantitative yields. Allihn bulb versions promote drip return, standard for 500ml reactions yielding ninety eight% purity.
