Consumables are the items labs burn through fastest — and the first to run out during a busy experiment week. From pipette tips to parafilm, keeping a well-stocked consumables cabinet prevents project delays. Here is the definitive checklist for Pakistani research labs, with bulk supply options from Bioworld Scientific (BWS).
PPE and Hand Protection
- Nitrile examination gloves — powder-free, S/M/L/XL (most versatile for chemistry and biology)
- Latex gloves — alternative where nitrile allergies are not a concern
- Heavy-duty chemical-resistant gloves — for solvent and acid handling
- Face masks and face shields — splash and aerosol protection
- Lab coats (disposable and reusable) — see our PPE guide
Pipette Tips
| Tip Type | Volume Range | Use Case |
|---|---|---|
| Universal tips (non-filter) | 10 µL – 1000 µL | General liquid handling |
| Filter tips (barrier) | 10 µL – 1000 µL | PCR, RNA work, contamination-sensitive assays |
| Low-retention tips | All sizes | Viscous samples, precious reagents |
| Extended-length tips | 200 µL, 1000 µL | Deep-well plates and tall tubes |
| Reload stacks / racks | 96-tip racks | High-throughput pipetting |
Filtration Consumables
- Syringe filters (0.22 µm and 0.45 µm) — sterile filtration of media and buffers
- Filter paper (Whatman grades) — gravity filtration, qualitative and quantitative
- Membrane filters (PVDF, nylon, cellulose) — HPLC sample prep, sterility testing
- Bottle-top filters (250 mL – 1 L) — bulk sterile media preparation
- Centrifugal filter units (Amicon-type) — protein concentration and desalting
Sealing, Wrapping, and Storage
- Parafilm M — universal sealing film for plates, flasks, and beakers
- Aluminium foil — light-sensitive reagent wrapping
- Microscope slide mailers and boxes — sample transport and storage
- Ziplock and sample bags — evidence and specimen handling
- Autoclave tape and indicator strips — sterilization verification
Cleaning and Surface Wipes
- Kimwipes / delicate task wipes — lint-free lens and cuvette cleaning
- Bench wipes (disinfectant) — daily decontamination of work surfaces
- Sponges and scrub pads — glassware washing
- Lab detergent (Alconox-type) — residue-free glassware cleaning
- 70% ethanol spray bottles — surface and BSC decontamination
Labels and Marking
- Cryo labels — remain adhesive at −80 °C and in liquid nitrogen
- Autoclave-resistant labels — for media bottles and waste bins
- Barcode labels — sample tracking and LIMS integration
- Permanent markers (fine tip) — writing on tubes, plates, and flasks
- Label tape and dispensers — colour-coded sample identification
Chromatography and Analytical Consumables
- TLC silica gel plates — thin-layer chromatography
- HPLC vials and caps (2 mL) — autosampler compatibility
- GC liners and septa — gas chromatography maintenance
- pH indicator strips — quick pH checks
- Cuvettes (quartz and plastic) — spectrophotometry
General Bench Consumables
- Weighing boats and paper — analytical balance use
- Spatulas (metal and plastic) — powder transfer
- Stirring rods and magnetic stir bars — mixing
- Timer and stopwatch — protocol timing
- Ice buckets and ice packs — cold reagent storage during experiments
- Sharps containers and biohazard bags — waste segregation
How Much to Stock?
A 10-person research lab typically consumes these monthly:
- 20–40 boxes of nitrile gloves
- 10–20 racks of 200 µL filter tips
- 5–10 rolls of parafilm
- 2–4 packs of syringe filters
- Multiple packs of Kimwipes and bench wipes
Bulk institutional pricing from BWS reduces per-unit cost significantly compared to ad-hoc purchasing.
