Consumables for Laboratory

Laboratory consumables are the single-use or limited-use items required to run daily tests, maintain accuracy, and prevent cross-contamination. Because they are used up or worn down during procedures, they require steady replenishment.

The essential laboratory consumables can be broken down into five primary categories:

1. Liquid Handling Supplies

Precise fluid transfer is critical to keeping testing reproducible.

• Pipette Tips: Disposable plastic tips (standard, filtered/barrier, or low-retention) designed to prevent cross-contamination between fluid samples.
• Syringes & Needles: Used for precise sample injection or drawing fluids.
• Reagent Reservoirs: Shallow troughs designed for multi-channel pipetting.

2. General Labware & Sample Containers

These are the vessels that hold, mix, spin, or store samples.

• Tubes & Microtubes: Includes microcentrifuge tubes (e.g., Eppendorf tubes), PCR strips, and conical centrifuge tubes (typically 15mL or 50mL) built to withstand high gravitational forces.
• Vials & Closures: Autosampler vials, cryovials for ultra-low temperature storage, and sample collection bottles.
• Cuvettes: Small, transparent tubes (plastic or quartz) used for holding samples during spectrophotometric analysis.
• Disposable Plastics: Plastic beakers, flasks, and graduated cylinders used when washing glassware isn’t practical or to avoid chemical interactions.

3. Life Science & Culture Supplies

Essential for microbiology, molecular biology, and clinical diagnostic labs.

• Petri Dishes & Culture Plates: Multi-well plates (96-well, 384-well) used for high-throughput screening, ELISA assays, or cell growth.
• Cell Culture Flasks: Specialized treated plastic vessels designed to promote cellular attachment and propagation.
• Swabs & Transport Media: Used to collect and preserve microbial or viral samples (like DNA/RNA) safely prior to extraction.

4. Filtration & Analytical Consumables

Used to purify solutions, separate components, or calibrate instruments.

• Filter Papers & Syringe Filters: Membrane filters (e.g., Nylon, PTFE, PVDF) used to remove particulates from samples before running them through delicate analytical equipment.
• pH Buffers & Standards: Chemical solutions used to calibrate pH meters, conductivity meters, and refractometers to guarantee testing accuracy.
• Chromatography Consumables: Septa, liners, and solid-phase extraction (SPE) cartridges.

5. Lab Safety & Personal Protective Equipment (PPE)

The first line of defense against chemical spills, biohazards, and minor workplace accidents.

• Gloves: Nitrile (most common for chemical resistance), latex, or vinyl.
• Face Protection: Safety goggles, face shields, and fluid-resistant surgical masks.
• Apparel: Disposable lab coats, shoe covers, and bouffant caps for cleanroom or sterile environments.
