Modern life science research runs on laboratory plasticware. From PCR amplification to mammalian cell culture, the right tubes, plates, and flasks protect sample integrity and keep experiments sterile. This guide lists the plasticware every Pakistani research lab should stock — available from Bioworld Scientific (BWS).
Tubes and Microcentrifuge Ware
- Microcentrifuge tubes (0.5, 1.5, 2.0 mL) — DNA/RNA storage, enzyme reactions, sample aliquots
- PCR tubes (0.2 mL) — individual tubes or 8-strip format for thermal cyclers
- PCR plates (96-well, semi-skirted) — high-throughput amplification
- Centrifuge tubes (15 and 50 mL conical) — cell pelleting, medium preparation
- Microcentrifuge tube racks — organization and bench stability
Microplates for Assays
| Plate Type | Format | Application |
|---|---|---|
| 96-well flat-bottom TC-treated | Sterile, with lid | CCK-8, ELISA, cell seeding |
| 96-well U-bottom | Non-TC or TC | Cell mixing, hemagglutination |
| 384-well plates | Low volume | High-throughput screening |
| Deep-well plates (1–2 mL) | 96-well | Sample storage, bacterial culture |
| Black/clear-bottom plates | 96-well | Fluorescence assays |
Cell Culture Flasks and Dishes
Cell culture plasticware must be tissue-culture (TC) treated and sterile. Essential items for your cell culture lab:
- T25, T75, and T175 cell culture flasks — vented caps, angled neck
- 6-well, 12-well, and 24-well plates — transfection, imaging, dose-response
- 100 mm and 150 mm Petri dishes — bacterial and mammalian culture
- Cell scrapers and spreaders — harvesting adherent cells
- Reservoir troughs — multichannel pipette reagent dispensing
Cryogenic Storage
- Cryogenic vials (1–2 mL, internal or external thread) — cell line banking at −80 °C or liquid nitrogen
- Cryo boxes and dividers — organized freezer storage (81-place standard)
- Cryo labels — remain legible at ultra-low temperatures
- Freezing containers (Mr. Frosty type) — controlled-rate freezing to −80 °C
Serological and Transfer Pipettes
- Serological pipettes (1, 2, 5, 10, 25, 50 mL) — sterile, individually wrapped
- Pasteur pipettes (plastic) — transfer and dropper applications
- Pipette controller (pipet-aid) — battery-powered serological pipetting
- Reagent reservoirs — 25 mL and 100 mL for 8-/12-channel pipettes
Bottles and Storage Containers
- Media bottles (125 mL – 1 L) — autoclavable, GL45 caps
- Reagent bottles (HDPE and PP) — chemical storage where glass is impractical
- Sample storage boxes — microtube and cryo vial organization
- Sharps containers — safe disposal of needles and broken plastic
Choosing the Right Plastic Material
| Material | Properties | Best For |
|---|---|---|
| Polypropylene (PP) | Autoclavable, chemical resistant | Microcentrifuge tubes, plates |
| Polystyrene (PS) | Clear, rigid, TC-treatable | Cell culture flasks, assay plates |
| Polyethylene (PE) | Flexible, low extractables | Wash bottles, storage bags |
| PC (polycarbonate) | High clarity, durable | Centrifuge tubes (high-speed) |
Sterility and Contamination Prevention
- Always use sterile plasticware inside biosafety cabinets for cell work.
- Check lot certificates for endotoxin-free and DNase/RNase-free claims on molecular biology products.
- Never reuse single-use culture plates or PCR tubes.
- Store opened sleeves in clean, dry conditions away from UV exposure.
- Pair plasticware with sterile pipette tips and gloves.
