Laboratory tongs and forceps: how can glassware, objects and samples be handled safely?

Indispensable on any bench, laboratory tweezers provide a reliable grip on samples, disposables and glassware—from sterile technique to transfers under a fume hood. Whether you need single-use tweezers to prevent contamination, precision tweezers to handle a delicate membrane, or heat-resistant glassware tongs, each design serves a specific task. Materials (316L stainless steel, PTFE, polymers), tip geometry, length, coatings and autoclave compatibility determine ergonomics, safety and longevity—for clean, reproducible and safe handling.

What types of laboratory tongs and forceps are there?

Several complementary families can be distinguished. The disposable forceps (PP or PS, often EO/?-sterile) prevent cross-contamination in microbiology and field sampling; smooth tips for delicate surfaces, serrated for a firm grip. The precision forceps (316L stainless steel, titanium) come with straight or curved, fine or bevelled tips, with antimagnetic and ESD-safe options for sensitive micromanipulation. The glassware tongs and clamps (test tubes, beakers, burettes) feature jaws lined with cork, fibre or silicone to secure hot glassware and minimise breakage; some mount on a retort stand. Finally, the membrane and slide forceps offer wide, perfectly smooth tips, sometimes PTFE-coated or fitted with PEEK ends, to handle 25–90 mm filters and microscope slides without marking.

In which fields are laboratory clamps used?

• Life sciences: sterile handling in Petri dishes, cell culture, tissue transfer, spotting onto membranes and microscope slides.
• Pharmaceutical/biotech: accurate weighing, sampling in ISO-classified areas, filter changes, particle monitoring.
• Food industry: HACCP sampling, filtration (47/90 mm), controlled contact with sensitive ingredients.
• Environment: field sampling, water/air filtration, handling in a fume cupboard or with gloves.
• Chemistry/cosmetics: picking up pellets/tablets, handling hot glassware, setting up burettes.
• Education/R&D: everyday versatility, safety and reproducibility of techniques.
Choose material, length and tips according to the sample matrix, required cleanliness level and operating temperature.

Frequently asked questions about lab clamps

How do I choose the right tweezer material?
316L stainless steel for durability and sterilisation, titanium for anti-magnetic use, PP/PS for sterile disposables, PTFE/PEEK tips for ultra-delicate surfaces.

Can single-use tweezers be autoclaved?
Most PS versions cannot withstand autoclaving. PP tolerates 121 °C, but the item remains 'single-use' to ensure asepsis and traceability.

Smooth or serrated tips: which should you choose?
Smooth for membranes/slides without marking; serrated for a firm grip on items or consumables. The choice depends on fragility and the clamping force required.

What length of tweezers should I choose?
11–15 cm for precision at the bench; 20–25 cm for deep bottles/flasks or work under a hood. The longer the tool, the less precise it is for the same applied force.

Anti-magnetic or ESD tweezers?
Useful near balances, sensors or ferromagnetic particles. Anti-magnetic prevents attraction; ESD protects against electrostatic discharge.

How do I care for stainless-steel tweezers?
Rinse after use, use a neutral detergent, dry thoroughly, sterilise if needed. Avoid prolonged exposure to concentrated chlorides; check tip alignment.

Which tongs for hot glassware?
Glassware tongs with silicone/cork-lined jaws, generous opening and a reliable spring. Always wear gloves/a face shield and check the grip before lifting.
