VEE GEE 6168-4721 is the replacement borosilicate glass support base body designed to receive the stainless steel screen in SIBATA 6168 series filter systems, sold individually. This glass base body is the lower glass housing component used in the stainless steel screen filter configurations — the 6168-0002 (300 mL SS screen kit) and 6168-0004 (100 mL SS screen kit). It pairs with the separate stainless steel screen (6168-4731) and PTFE gasket (6168-4741) to form the complete removable SS screen base assembly. Autoclavable at 121°C. Glass body only — screen, gasket, funnel, stopper, and clamp sold separately.
Features & Benefits
- Glass Body for SS Screen Assembly: This is the borosilicate glass lower body that houses the removable stainless steel screen in the 6168 SS screen filter configurations. It differs from the fritted glass support base (6168-4722), which has a fused coarse-frit glass filter support built in. This base has a smooth glass seat that accepts the removable stainless steel screen (6168-4731) and PTFE gasket (6168-4741).
- Borosilicate Glass — Chemical Resistance: Resistant to acids, bases, solvents, and biological reagents; transparent for observation of the filtration path; durable and cleanable with standard lab procedures.
- Autoclavable at 121°C: Sterilizable at 121°C (250°F) for 20 minutes — consistent with full 6168 kit autoclavability requirements.
- 47 mm Filter Compatibility: Designed for the 47 mm filter format used throughout the 6168 series — accepts the standard stainless steel screen and PTFE gasket sub-assembly for the 47 mm filter diameter.
- SIBATA Precision Manufacturing: Manufactured by SIBATA Scientific Technology Ltd. to Japanese precision standards.
- 1-Year Warranty: Backed by VEE GEE Scientific's standard accessory warranty.

Frequently Asked Questions
What is the difference between 6168-4721 and 6168-4722?
The 6168-4721 is the glass body designed to receive the removable stainless steel screen (6168-4731) and PTFE gasket (6168-4741) — it has a smooth glass seat and no built-in filter support. The 6168-4722 is the fritted glass support base, which has a fused coarse-frit glass disk permanently built into the body to support the filter membrane directly. Use the 6168-4721 in stainless steel screen configurations; use the 6168-4722 in fritted glass configurations.
Do I need to order the stainless steel screen and PTFE gasket separately?
Yes. This listing is for the glass base body only. To assemble a complete SS screen base, you also need the stainless steel screen (6168-4731) and the PTFE gasket (6168-4741). If you also need a funnel, stopper, and clamp, the complete 6168-0002 (300 mL) or 6168-0004 (100 mL) kit includes all components.
