Laboratory Tongs and Forceps Singapore: Types, Materials & Selection Guide
Laboratory tongs and forceps are among the most fundamental hand tools in any working laboratory. Whether you are transferring a red-hot crucible from a muffle furnace, lifting a freshly autoclaved beaker, or placing a delicate coverslip under a microscope, the right gripping tool protects both the operator and the sample. For Singapore laboratories — from food testing facilities and pharmaceutical QC labs to academic research groups at NUS, NTU, and A*STAR — reliable tongs and forceps are an everyday necessity that directly affects safety and workflow efficiency.
At JW RESEARCH SUPPLY, we supply Singapore laboratories with a complete range of laboratory tongs, forceps, and tweezers in stainless steel, nickel-plated steel, PTFE, polypropylene, and ceramic-tipped designs. This guide explains the different types, materials, and selection criteria so you can choose the right tool for each application.
Why the Right Gripping Tool Matters
Using the wrong tongs or forceps is not just inconvenient — it is a safety and contamination risk. Standard laboratory tongs with PVC or rubber grips protect hands from heat but must never contact flames. Forceps made from the wrong material can scratch precision surfaces, leach metal ions into trace analysis samples, or lose their grip under repeated sterilisation. Selecting the correct tool for each task reduces burn injuries, sample loss, and cross-contamination.
Types of Laboratory Tongs and Forceps
| Type | Material | Heat Resistance | Typical Applications |
|---|---|---|---|
| Crucible Tongs | Stainless steel, nickel-plated steel | Up to 800 °C (with insulated handles) | Handling crucibles from muffle furnaces, drying ovens, and hot plates |
| Beaker / Utility Tongs | Stainless steel with PVC or rubber grips | Heat-resistant grips to ~150 °C | Lifting beakers, flasks, and bottles during heating and autoclaving |
| Test Tube Holder / Tongs | Steel wire or stainless steel, spring-loaded | Moderate (not for open flames) | Holding test tubes during heating, mixing, and water bath work |
| Utility Forceps (12–25 cm) | Stainless steel, serrated or plain tips | Autoclavable | General manipulation: weighing boats, membranes, filters, small parts |
| Precision Tweezers | Stainless steel, anti-magnetic, ESD-safe | Autoclavable | Microscope work, electronics, fine assembly, tissue handling |
| Plastic / PTFE Forceps | PTFE, polypropylene, nylon | PTFE up to 260 °C; PP up to 135 °C | Acid handling, cleanroom use, scratch-free and metal-free work |
Material Selection Guide
The material of your tongs or forceps determines chemical resistance, heat tolerance, and suitability for clean analytical work:
- Stainless steel (304/316) — The workhorse material for general labs: corrosion-resistant, autoclavable, and strong. 316 grade offers better resistance to chlorides and aggressive reagents.
- Nickel-plated steel — Economical choice for crucible and general-purpose tongs where moderate heat and chemical exposure are expected.
- PTFE (Teflon) — Chemically inert, ideal for strong acids and solvents, and safe for non-scratch contact with soft or polished surfaces.
- Polypropylene (PP) — Lightweight, economical, and chemical-resistant for routine aqueous work; autoclavable up to ~135 °C.
- Ceramic-tipped — Combines metal strength with non-reactive, non-scratch ceramic tips for high-temperature and contamination-sensitive handling.
Key Selection Criteria
- Match the tool to the object size — Large crucibles and beakers need full-size tongs; small parts and membranes need fine-tipped forceps or precision tweezers.
- Consider temperature exposure — For furnace and hot-plate work, choose metal tongs with insulated grips rated for the temperature; never use plastic-coated tools near heat.
- Avoid metal contamination — For trace metal analysis and cleanroom protocols, use PTFE or dedicated plastic forceps to eliminate metal ion leaching.
- Check sterilisation compatibility — If you autoclave routinely, confirm the tool is autoclavable and choose 316 stainless for long service life.
- Grip design — Serrated tips hold firmly on glassware; smooth, angled tips suit precision manipulation; spring-action handles reduce hand fatigue during repeated use.
Safe Handling Best Practices
- Inspect before use — Check for worn grips, bent tips, or loose hinges that could cause dropped hot glassware or samples.
- Keep hands clear — When lifting hot items, keep fingers behind the grips and use tongs long enough to keep a safe distance.
- Pre-position for hot transfers — Have your destination (heat block, rack, or desiccator) ready before lifting a hot crucible or beaker.
- Clean after use — Wipe forceps clean after contact with reagents; autoclave stainless steel tools between critical tasks.
- Store properly — Hang tongs or store them flat in drawers with tips protected to avoid bending and cross-contamination.

Frequently Asked Questions
Q: What is the difference between laboratory tongs and forceps?
Tongs are large, two-arm gripping tools used to handle bulky or hot objects such as crucibles, beakers, flasks, and evaporating dishes. Forceps (also called tweezers) are small, precision instruments used to grasp, manipulate, or transfer small objects such as coverslips, membranes, weighing papers, and tissue samples. Choose tongs for hot and heavy glassware, and forceps for fine manipulation work.
Q: Can stainless steel forceps be autoclaved?
Yes. High-quality stainless steel forceps (typically 304 or 316 grade) are autoclavable at 121–134 °C and can also be sterilised by dry heat, chemical sterilants, or flaming. Plastic forceps, including PTFE and polypropylene types, are generally not autoclavable unless specifically stated — always check the manufacturer's sterilisation instructions before reuse.
Q: Which tongs should I use for hot crucibles and muffle furnaces?
Use stainless steel crucible tongs with a firm scissor-style grip and curved, serrated tips that can securely hold the crucible body. For work at very high temperatures (above 300 °C), choose tongs with long insulated or heat-resistant handles to keep your hands away from the heat source. Never use plastic-coated tongs near flames or hot plates, as the coating will melt.
Q: How do I choose between plastic and stainless steel forceps?
Choose stainless steel forceps for chemical resistance, sterilisation, and durability — they suit most general lab work, including organic solvents and heat exposure. Choose plastic forceps (PTFE, PP, or nylon) when you need to avoid scratching soft surfaces, prevent metal contamination in trace analysis, or work with acids that would corrode steel. For cleanrooms and analytical work, single-use or dedicated material-matched forceps help avoid contamination.
