Cork piston pad, wooden circle tray, mat ring and round piston holder — functional cork and wood supports designed for laboratory use. Each piece protects equipment, increases stability and preserves shape under regular use. Key benefits Impact protection (Cork piston pad): soft cork cushions the piston, reducing shock and the risk of damage or breakage when a piston contacts a hard surface or during handling on a laboratory stand. Secure support (Wooden circle tray): provides a stable base for bottle corks and laboratory flasks; serves as a round floor holder for pistons and a compact tray for placing cork-mounted containers. Improved grip (Mat ring): grooved base design increases contact and friction with bench surfaces, helping bottles and flasks stay firmly in place during routine work. Durability (Round piston holder): cork’s inherent resilience keeps the holder in shape through repeated use, maintaining reliable support for laboratory supplies. Material and performance Materials: natural cork components and a wooden circular tray combine cushioning and structural support. Function: shock absorption for pistons, stable seating for cork-mounted bottles and flasks, and slip-resistant base performance from the grooved mat ring. Compatibility: intended for use with laboratory pistons, bottles, flasks and standard laboratory stands or benchtop setups where cork support and protection are required. Practical applications (use scenarios) Assembly and storage: place the cork piston pad or round piston holder under a piston on a laboratory stand to prevent direct hard-surface contact during assembly, adjustment or storage, reducing the chance of chipping or deformation. Sample preparation and titration: set flasks or reagent bottles on the wooden circle tray with the mat ring underneath to stabilize glassware during transfers, measurements or titrations, minimizing movement and spillage risk. Transport and handling within the lab: use the cork piston pad and tray to cushion and seat small glass vessels or piston assemblies during short moves between stations, protecting fragile parts and keeping components organized. Why choose these parts Purpose-built for lab use: designed to protect pistons and stabilize glassware without altering your existing equipment or workflows. Simple, passive protection: no installation required; components provide immediate cushioning and grip where needed. Long-lasting support: cork’s resilience and the wooden tray’s stable base deliver repeated use without rapid wear or loss of shape. Contents and typical placement Cork piston pad: fits beneath pistons or piston heads on laboratory stands to absorb impact. Wooden circle tray: accepts cork-mounted bottles and flasks as a flat, stable support. Mat ring: placed under bottles or trays to add grip via its grooved base. Round piston holder: used where a compact, durable cork support is needed to hold piston parts upright or isolated from hard surfaces. Notes for use Use as supplied on laboratory benches or stands to reduce direct contact between fragile components and hard surfaces. Combine pieces (tray + mat ring, piston pad + holder) for extra stability and protection when required. This set provides straightforward, reliable cushioning and support for pistons, bottles and flasks in laboratory environments, reducing damage risk and improving bench stability without complicated installation.
