10ml Glass Vial Tray

Drop impact · side wall contact prevention

Each vial sits in a precision-clearanced cavity (0.25 mm per side). When the box is dropped laterally, the vial experiences deceleration force through the tray wall - not through direct glass-to-glass or glass-to-cardboard contact. The tray wall material absorbs the initial impact energy and distributes it across the full cavity circumference.

✓0.25 mm cavity gap - controlled deceleration

✓Glass never contacts box wall directly

✓Impact distributed across full cavity ring

≥ 3mm between cavities · zero glass contact

The inter-cavity wall between adjacent vials is a minimum 3.0 mm thick. This ensures that even if the tray deforms slightly under lateral impact, the glass of adjacent vials cannot contact each other. Glass-to-glass contact is the single most common mechanism for vial chipping and cracking during distribution - this separation eliminates the risk entirely.

✓≥ 3.0 mm plastic wall between all cavities

✓Zero glass-to-glass contact possible

✓Chipping / cracking mechanism eliminated

±0.3 mm tray-to-box · no cyclic rattle

The ±0.3 mm tray outer-to-box-interior clearance prevents the tray from rattling inside the box under road and air transport vibration. A loose tray creates cyclic glass-wall micro-impacts at vibration frequency - even at low energy per cycle, 10,000+ impacts during a long-haul shipment accumulate into fatigue cracks. The box-lock fit eliminates this by immobilising the tray.

✓±0.3 mm prevents cyclic rattle in transit

✓Tray immobilised at all shipping orientations

✓Vibration fatigue crack mechanism suppressed

Vials held upright · stopper stays dry

The tray cavity geometry maintains the vial cap-up at all times during storage and distribution. For peptide vials sealed with a rubber stopper and aluminium crimp, this orientation keeps the stopper dry - critical for lyophilised peptides where moisture ingress through the stopper is a degradation pathway. The vial base is cradled at the cavity floor; the cap protrudes 2 mm above the tray face.

✓Cap-up geometry maintained throughout

✓Stopper not immersed - lyophilised product safe

✓Cap protrudes 2mm - easy visual check

−20°C standard · −80°C PETG option

PVC and APET maintain impact resistance and dimensional stability from −20°C to +40°C - covering standard peptide cold-chain requirements (2–8°C refrigerated, −20°C frozen). For biologics requiring −80°C storage, PETG material is specified, which maintains flexibility and impact resistance at ultra-low temperatures where PVC and standard PET become brittle.

✓PVC/APET: −20°C to +40°C - peptide standard

✓PETG option: −80°C impact resistant

✓No dimensional change from −20°C to room temp

Label integrity throughout cold storage

Peptide vials are stored refrigerated for weeks to months before use. Without tray support, vials in a box contact adjacent vials and box walls with every minor vibration event, progressively abrading the label. The insert tray keeps each vial isolated in its cavity - no glass-label contact with adjacent vials, no label contact with cardboard. Label readability is maintained for the entire storage period.

✓No glass-to-label abrasion during storage

✓Label readable throughout refrigerated shelf life

✓Lot number / concentration visible at point of use
